• Binder can be a sugar and polymer.
• Natural polymers binder: starch, gum (Acacia, tragacanth, gelatin)
• Synthetic polymers binder: PVP, methylcellulose, ethylcellulosa, hidroxypropylcellulosa\
• Can be used in dry or wet granulation. Wet method requires less material.\
• The amount of binder solution required for the 3 kg of filler are listed in the table

1. Starch (Amylum)
• Can be used as a filler, binder, and the disintegrant
• In the form of starch amili 5-10%
• Preparation :suspend starch 1:1 / 2-1 in cold water, add boiling water 2-4 times with constant stirring until the starch that can expand into a transparent diluted
• Another way: a suspension of starch in water heated
• Contains 11-14% water content, will cause the tablet disintegrated quickly - The making must be careful in order to obtain a good starch, is not hydrolyzed, and not making
• Best Use of a maximum of 30%. If a large dose of active ingredient, starch was replaced with a better disintegrant, namely Avicel.
• Tablets containing a high concentration of starch tablets showed a fragile and difficult to be dried
• Unmodified starch does not have good compressibility properties and have a great friability, and the occurrence of capping in tablets if used in large quantities

As disintegrant:
• Usage: 1-20%, is the most commonly used disintegrant
• Mechanism of action by forming hydrogen bonds during compression and rupture or expand when water entered Mell pore (capillary)
• Use is tailored to the type of starch, compression pressure, and water content of the mass
• Caution: before use, starch must be dried at a temperature of 80-90C to remove absorbed water

2. Starch 1500
• Can be used as a binder in wet & dry granulation, and disintegrant
• Starch 1500 containing 20% maximum water-soluble fraction that functions as a binder while the rest are as disintegrant
• Starch 1500 takes ± 3-4 times as much starch amylum to produce tablets with the same hardness
• Should not be used as a filler in wet granulation because it will produce a gel that serves as a powerful binder
• As disintegrant, can be added in dry state, in the outer phase.
• The good flow is directly compressible starch
• Can be compressed own, but if mixed with 5-10% of drugs requires additional lubricant (eg, 0.25% colloidal silicon dioxide)
• Containing 10% moisture and cause the tablets become soft when combined with magnesium stearate> 0.5%, stearic acid used as a substitute

As disintegrant:
• Represents good disintegrant and added to the dry mixture (in inner phase or outer phase in dry granulation or direct compression, or in the external phase on the wet granulation method)
• Caution: should not be given to the wet mass

3. Pregelatinized Starch
• It is a starch that has been cooked and dried again. Can be used as a substitute for starch paste is more easily soluble in warm water without heating
• Can be added to dry into a powder and then moistened with water to form moist mass


Is an inert substance that is added in tablet formula intended to create a tablet weight as expected.
Usually tablets containing the active substance with a small dose requires a lot of filler material. If the tablet has big dose of active substance, the filler slightly or not at all.

1. Avicel (Microcrystalline Cellulose)
• Avicel 103 has the advantage compared with 101, 102 because of small specific volume, better flow and a shorter disintegration time.
• Insoluble, non-reactive, the flow is not good, hold 50% capacity.
• Generate a hard tablet with a small pressure (compressibility good) and low friability tablets, long-time stability.
• Generate a fast wetting and thus distribute the liquid evenly to the entire mass of powder; produce drug distribution and a uniform color.
• Acting as an auxiliary binding, resulting in a hard granules with minimal fines.
• Can be act as dry binder, disintegrant, lubricant and glidan.
• Its use requires a lubricant; its use can be combined with lactose, mannitol, starch, calcium sulfate.
• Helps overcome substances that if overwetting (too wet) to something like "clay" is difficult and when dry granulated , the granule becomes hard and resistant to disintegration. Example: kaolin, calcium carbonate.
• Avicel in wet granulation improve ties in the compression, reducing the capping and friability of tablets.
• Avicel assist with water-soluble drugs for homogeneous, preventing migration of water soluble dyes and helps for quick evaporation and uniform.
• For drugs with small doses, Avicel used as a filler and binder addition.
• 60% Avicel PH 101 and 40% amylum as 10% starch as a paste made easy moist granulated mass, forming a strong granules on drying with less fine than that just paste made from starch.
• Form PH 101: powder, PH 102: granule, PH 103: powder

As disintegrant:
- It is a very good disintegrant, especially at concentrations of 10% or higher.
- In wet granulation method, Avicel don’t have disintegrant properties.
- Attention: at high concentrations, Avicel can cause sticky on the tongue.

2. Calcium sulfate trihydrate
• Used as a filler for granulation with the amount of active ingredient 20-30%.
- Synonym: terra alba, snow white filler.
- Insoluble, non-hygroscopic.
- The higher the grade, increasingly white, most inexpensive filler, the active substance can be used for acidic, neutral, alkaline, have high absorban capacity for oil.
- Binder suggested: PVP, Croscarmellose, starch paste.

3. Calcium phosphate dibasic
• Used as a filler and binder for direct compression with the smallest in size, not expensive, can not be used with acid compounds or acid salt
• If you use a liquid binder that is too much then so sticky and hard, can not be granulated so that the solution combined with the starch / Avicel

Properties of Some Tablet Ingredients

1. Fines
The maximum amount of fines is 30% of the weight of the tablet, including the outer phase. If the total amount of fines more than 30% big possibility capping will occur. Different amounts, different distributions can be resolved by Hoover that does not vibrate and / or a add stirrer on the compression machine.

2. Eksplotab
Eksplotab is not an acid-resistant ingredient and only use as disintegrant in the outer phase, can not be able to be used for wet granulation. Use 3-5%, maximum 25%.

3. Starch 1500
Filler for direct compression tablets. If there is water, it going into gel so that the active substances are blocked, power expands less so disintegrant time will be long. Use as tablet filler : no more than 30%.

4. Avicel pH 101,102,103 good for direct compression tablet

Tablets Effervecent Ingredients

It should be noted that the ingredients used in tablet effervescent should have the contents moist very low and when the manufacture of this preparation must be done in a dry place.

Characteristic of Effervescent tablet ingredients:

1. In many ways, the principles used in producing Effervescent tablets similar to those used for conventional tablets. Many of the processes and tools the same process. Likewise, the general nature of granules required for obtaining tablets according to the requirements such as:
  • Particle Size
  • Particle shape
  • Granulometri
  • Uniformity of distribution
  • Free flow of granules
  • Granules must be compressed

2. The nature of raw materials selected for use in Effervescent Tablets that more important than tablets conventional is the moisture content, which means the raw materials used must be dry.
If the raw material used is not dry (containing moisture), then acid reaction will occur the carbonate will cause the product to be physically unstable and decompose. Once started the reaction it will continue much faster because the byproducts reaction is water added.

CH2COOH + 3NaHCO3 CHCOONa + 3 CO2 + 3 H2O

Therefore, the raw materials used must be in anhydrous (dry) with a few levels humid absorbed. The water molecule is still there but very little because it takes a little water to bind the granules because if the granules too dry, granules can not be compressed.

Effervescent Tablet : Developing and Method of Manufacturing

Effervecent tablets made by some method, that is by wet granulation, dry granulation, and the method of fluidization. Fluidization method wurster method, using a special spray equipment complete with channels spray binder and air duct heating.

Effervescent Tablet requires require special conditions and methods for its production because there are two ingredients that can not be united which is salt sodium bicarbonate and organic acid as a producer of carbon dioxide. The second reaction, this material will be accelerated by the presence of water, therefore Effervescent tablet during its journey from the end of production into the hands of patients should not be the slightest contact with water. In addition, high temperatures can also accelerate the

Effervescent tablet-making process requires special conditions, humidity should be relatively low and the temperature must be cold to prevent the granules or tablets attached to the machine because of the effect of moisture from the air.

Problems On Some Active Compounds in Formulating Tablet

• Papaverine HCl,
if used water in formulating, this drug will dissolve, then use solvents that do not dissolve the active ingredient

•Hydrophobic substance (phenylbutazone, Vioform, Paracetamol, and chloramphenicol esther)
In formulatin g hydrophobic substances, you can add Tween 80 0.01% or saponin 5% of weight of the tablet (add mucilago amyli as much as 0.03%)

• Diazepam
if made granule, Diazepam will become rough granules, therefore, should be smoothed first.

•Vitamin C and Paracetamol
In preparing combination of vitamin C and paracetamol, you should use a non-water solvent, and dry with a dehumidifier.

Vitamin C Effervescent Tablet : Formula, Manufacturing and Consideration of Material and Method of Manufacture Selection

One effervescent tablet made with weights 1.5 grams (1500 mg).
Formula for 1 piece of Vitamin C effervescent tablets:

  • Vitamin C 500 mg

  4. Filter off the microcapsules and dry them.

The above mentioned microcapsules of Rifampicin may be blended with other anti-tubercular drugs and suitable excipients to formulate into tablets, capsules or suspension.

Special Problem in Compressing Tablet Process

1. Sticky on Die

  • Inherent in the die and difficult to remove
  • Loud noise in engine
  • Tablet brittle, ugly, rough side of the tablet, sometimes black

  • Antidherent less
  • lack of or improper lubricant
  • Example: Tablet aspirin sticky with Magnesium stearate, stearic acid should be used (which micronize because the function of lubricant between the particles are so fine that will be covered by the lubricant).
  • Water content is high will cause the attachment or sticky on the die, while low water levels can cause the laminating or capping.
  • The possibility of chemical or physical interaction, example :physical interaction between etoxy benzamin with caffeine, glyceryl guaiacolate with promethazine HCl, which are melting so high adhesives and eventually become sticky.
  • Raw materials with very low melting point. Example: Ibuprofen, glyceryl guaiacolate, Ciprofloxacin (antibiotic imidazole derivatives).

Settlement Issues/Problem Solution:
  • Improve antiadherent and lubricants
  • Replacement of a suitable lubricant
  • Reduce the number of coarse granules
  • Reduce the amount of water but do not get under the optimum, because the tablet becomes less good. If you already know the amount of wetting agent, carried out by adding the wetting agent to a binder solution, ie materials that do not evaporate but wet, for example : Propylene glycol or glycerin.
  • If there is sticky because of the punch and die may be damaged, because if defects in the punch, it will be attached so that the smooth punch and die.
  • If possible compressing at low temperature and low humidity due specifically to the active ingredient with a low melting point or eutectic mixture occurs, the eutectic mixture of substances more easily absorb water. Example: The combination of ampicillin with Clavulanic acid, where clavulanic acid easily destroyed by high humidity and temperature. Therefore, the manufacturing is done in a low temperature and RH.
  • Change of filler, filler material with high melting point and can adsorbing, such as SiO2 and Aerosil (adsorbent). Aerosil Addition in tablet tablets will cause the appearance of good, clear and shiny, but the longer the disintegration time.

Problems In Preparation Tablets

Problems that may arise is with regard to how to make good preparations and in accordance with their intended use.

To make good preparations needed pre-formulation data covering stability, organoleptic, physicochemical properties, and other data that can be expected to support the raw materials that are suitable for the formation of a preparation is good and the achievement of the intended use.

As for the problems that may occur:

1. Incompatible active substance (melting, change color, decompose, and so on).

Rifampicin and Isoniazid Fixed Dose Combination Tablet (Rifampicin-Isoniazid FDC Tablet) Pre-Formulation

Fixed dose combination (FDC) formulations became popular in the treatment of tuberculosis (TB) because of the better patient compliance, reduced risk of monotherapy and emergence of drug resistance in contrast to treatment with separate formulations of two to four first-line drugs.
It has been reported that the poor absorption of rifampicin from combination products may be due to decomposition of the drug in acidic stomach conditions, which is accelerated in the presence of isoniazid The mechanism of this degradation was proposed by Singh et al.

Problems in Formulating TBC Drug FDC (Rifampicin and Isonazid Tablet)

Studies revealed that the decomposition of rifampicin in acidic conditions in the absence of isoniazid stopped at the formation of 3-formylrifamycin, while the reaction in the presence of isoniazid proceeded to form a hydrazone between 3-formylrifamycin and isoniazid. Further, it was suggested that once 3-formylrifamycin is formed, it interacts with isoniazid to form the hydrazone, through a fast second order reaction. As hydrazone are unstable in acid conditions, 3-formylrifamycin and isoniazid are regenerated in areversible manner through a slower first order reaction. In this complex reaction process, rifampicin is further degraded, while isoniazid is recovered.

Combination products of rifampicin and isoniazid form isonicotinyl hydrazone (HYD) as a result of the interaction of the imine group of rifampicin and the amino group of isoniazid. While this reaction is slow in a solid state, it increases exponentially in the presence of acid and other tubercular drugs, such as ethambutol hydrochloride and pyrazinamide. The interaction between rifampicin and isoniazid came to light after a pharmacokinetic study of rifampicin in combination products the gastric acid led to a significant degradation of rifampicin, resulting in a 32% reduction in bioavailability Preformulation studies and a forced degradation study can detect such interactions much earlier.

Tablet Weight Variation: What Causes It and How to Deal Weight Variations

In the process of compressing a tablet, of course there are problems, one of them is the weight variation. Usually, the range is still tolerable for large-sized tablets (diameter> 10 mm) was 3%, while for small tablet (diameter <7mm) is 5%. However, this specification ranges vary depending on the respective industry and the active ingredient of the drug. If the active ingredient is an extremely potent drug, in terms of the number of doses are very small (microgram scale) has a large effect, then the range specifications for tablet weight variation would be minimized.

Tablet weight variation in compressing process is not a trivial thing. Moreover, when affecting the uniformity of dosage units.

Tablet weight variation may be caused by:
  • Distribution at Hoover caused the vibration. So, small granule pushed, large granules will come out first, because there is a process of consolidation. Therefore, needs to be put a uniform granule size. So, before the compressing process begins, better evaluation the particle size distribution first.
  • The flow of granules is not good / not free-flowing granules
  • particle distribution is not normal, because the specific gravity is different, so that the flow is bad.
  • Keep the uniform of particle size distribution. Not too many fines and not too many granules. Granules with a large particle diameter which causes the resultant tablet has a variety of unsightly weight, while too fine granules which causes unsightly flow time.
  • lubricant or glidant less or not mixed evenly. 

Special Problems That Exist When Formulating Some Tablets

1. Eutectic Mixture
Weigh both the active substance in proportion, put in a mortar and crushed. If it’s melting means eutectic.
Another way is, after both active ingredient mixed, add starch (musilago) with water, if it’s not dry not, mean eutectic, or you can replace starch with PVP alcohol.

2. Ethambutol Tablet Preparation and Formulation
Must be coat with the coating solution that alcohol-soluble and fatty acids soluble but not water soluble, preferably coated with Cetosel. Ethambutol if granulated with PVP / alcohol will be more cake. So, direct compression or dry granulation / slugging more prefer ble. With slugging, compactness will go down, but friability will be up. The technique of PVP addition : add PVP first into the mass then add alcohol until homogenous, so, the total amount is right.

3. Vitamin C
Do not use Avicel, this speed up the oxidation of vitamin C. Can be used in PVP, but the result is not good. Put starch in the vacuum or could also be used Cetosel in alcohol / eksplotab / starch. Do not use with wet granulation because of the disintegration time would be bad.

Avicel is a good use if not compatible with the active substance. Avicel could be used in direct compression, or wet granulation as a filler. If Avicel not water soluble, it can act as in the outer phase and inner phase.
If Avicel used in external phase, dry starch should be removed. So, the composition of outer phase is:

R /
Avicel 6%
Talk 1% (net)
Mg stearate 1%

Likewise, if used Aerosil in outer phase, talk was reduce because it has functioned well as glidant.

4. Starch
Starch is a good amount of 30%. If the amount is high, added substance Starch 1500 30%, then weight of the tablet will be even greater, while that have to be added is a lubricant, glidant, then starch added should be less than 30% which makes the flow to be poor. To overcome this, use Avicel which can act as a filler also disintegrant.
The combination of Starch 1500 and Eksplotab is good for the manufacture of tablets by direct compression as a disintegrant, should not be used as filler.

5. Dry Granulation Manufacturing
ARC 591 do not use alcohol-containing water (use alcohol that is not watery). If containingwater, it can be difficult to reconstituted.

6. Use of Pharmacot, Etocel, PVP
Only for active substances that must not hit the water (because it will decompose). The combination of starch 1500 and Avicel only for directcompression, the amount of Avicel should be reduced and the amount of Starch is 30%. Starch 1500 is not allowed to wet granulation with starch as a filler because the water will form a gel that can serve as a strong binder. But, as the crusher to SL can be used with wet granulation technique.

7. Extracts for Tablet
Condensed extract was dissolved in 70% ethanol and then dried with SL (Saccharum Lactis). For Belladona extract the composition is 1:3.

Pre-Formulation, Formulation and Manufacturing of Aspirin Chewable Tablet for Children

Acetylsalicylic Acid, also known by trade name Aspirin, is an acetyl derivative of salicylic acid that is a white, crystalline, weakly acidic substance, with melting point 137°C. It is useful in the relief of headache and muscle and joint aches. Aspirin is also effective in reducing fever, inflammation, and swelling and thus has been used for treatment of rheumatoid arthritis, rheumatic fever, and mild infection. Large doses cause acid-base imbalance and respiratory disturbances and can be fatal, especially in children. Acetaminophen (known by trade name Tylenol), which does not cause gastric irritation but does lower fever and relieve pain, is often substituted for Aspirin.

Chewing chewable tablets of aspirin produces the most rapid and biggest absorption compared to swallowing solid tablets or chewing and then swallowing solid tablets.

ANTI-MOSQUITO LOTION : Formula, Preparation and Evaluation

According to WHO, Indonesia is a country of endemic dengue fever mosquito. Approximately 2-5% of the world population is in danger of dengue fever disease. It is necessary to make an action for this outbreak is not widespread, and one way is by controlling disease vectors and self protection.

Lots of synthetic insecticides that can cause side effects and resistance, make people switch to products derived from natural materials. One is a plant that can be used is lemongrass (Cymbopogon nardus), which has a volatile oil content of which geraniol, methyl heptenon, and especially is citronellal. Content of these are toxic and can cause death due to fluid loss mosquito constantly so it will lack body fluids.

Some dosage forms have been tried to create a formula anti mosquito, one of the most popular dosage form lotions. This is due to ease of use and practical. Lotion is an emulsion, so we need a proper surfactant. Some things to consider in making preparations lotion is stability. Lotion would be damaged if disturbed system alloys mainly due to changes in temperature and composition are not sesai with prescribed dose.

Gardenia blue has been found stable at pH 3.5 and water solubility 7. Pikosianin does not dissolve in acid solubility (pH 3) and denatured at temperatures above 450C at pH 5 and 7. Which leads to discoloration. Exposed to visible light from 3x105 lux for 24 hours in water solubility at pH 5 and 7 caused 80% degraded.

To top of gardenia blue absorption is not dependent on pH (at pH 3, 5 and 7), with a maximum wavelength (╬╗maks) 596 nm. But its maximum absorption is determined by the amino acids used to form the blue color of the gardenia, in the range of wavelengths between 580 nm to 597 nm

The spectrum of pikosianin influenced by pH and maximum wavelength at 616 nm and 620 nm, especially for pH 5 and 7. Variations of pikosianin ╬╗maks value depends on the pH and the ratio 620 nm/280 nm for states that pikosianin is an unstable compound and composition variations may depend on sources, production methods and materials - material enhancements.

Stability of Natural Dyes on Light Blue : Gardenia blue, Phycocyanin, and Indigo

Three blue (Gardenia blue, phycocyanin, and indigo) has a maximum wavelength of 313 nm and 600 nm.

A. Blue Gardenia
Gardenia blue has been found stable at temperatures up to 800C in water solubility pH 3.5 and 7. When exposed to visible light from 3x105 lux for 24 hours resulted in approximately 50% degraded in water solubility.

Number of gardenia degraded by light with high intensity will depend on the number of amino acids used to prepare the blue color of the gardenia. In general, blue gardenia can remain stable even if exposed to light exposure is lower than like the ones in supermarkets (approximately 1500 Lux).

B. Phycocianin
Phycocianin known to be unstable on heating and lighting in the water solubility. When exposed to visible light from 3x105 lux for 24 hours in water solubility at pH 5 and 7 caused 80% portion degraded.


Consumer attention to the security dye synthesis increased use of natural dyes. Blue dye can be used in the long term, lead to an increased use of natural blue color, especially in food and beverage industry. Use food coloring to note the stability in the knowledge of degradation processes, the optimization of production, packaging and storage. Such as to heat and light of a natural dye that is blue and gardenia blue, and indigo pycocianin recently conducted a study to staining solutions

Mosquito Repellent Aerosol Formula and Manufacturing

Choosing The active ingredient
For a material to be valuable as a mosquito repellent, it must meet certain criteria :
  • effectively discourage insect attack on the treated area for hours and on different types of surfaces.
  • work under a variety of different environmental conditions.
  • not toxic or cause irritation when applied to human or animal skin.
  • it must be cosmetically acceptable, having a pleasant odor, taste, and feel.
  • harmless to clothing.
  • relatively low cost and effective against other common types of insects, such as flies.
The active ingredients contained in the mosquito repellents generally make up 5-30% of the final products. DEET (n, n-diethyl-m-toluamide) has been used more than any other. DEET is the compound which results from a reaction of m- toluic acid with thionyl chloride followed by a reaction with diethyl amine.

Other repellent ingredients used include citronella oil, dimethyl phthalate, lavender, lemon-grass oil, and peppermint oil. It has been found that mixtures of various repellent compounds often provide greater effectiveness than any one compound alone.

Rosuvastatin Tablet Formulation and Manufacturing

Manufacturing of stable tablet containing rosuvastatin can not be accomplished only by using pH adjuvant compounds. Presence of inorganic salts of multivalent metals is also required to prevent the formation of lactone and oxidation decomposition products. Stability of statin also can be obtained by adding amino sugars (e.g. N-methyl-glucoseamine). The advantage of the amino sugars versus inorganic alkali-earth metal salts is that they do not irritate the mucosa in the intestines, but of course tht prize is higher.

In the pharmaceutical composition inorganic salts of multivalent metals (Ca, Mg, Zn, Al, Fe and the combinations thereof) are used as stabilizing additives such as aluminum, magnesium metasilicate, tribasic calcium phosphate, tribasic magnesium phosphate and tribasic aluminum phosphate. The marketed (under Crestor trade name) pharmaceutical composition contains tribasic calcium phosphate as stabilizing agent.

It is known from the literature that from among HMG-CoA reductase inhibitor, lipid-lowering drugs several compounds are sensitive to the properties of the micro-environment of the composition, in fact to light, to heat and humidity.

Pregelatinized starches have been used for a long time in the food industry, so does in Pharmaceutical industries. Starch 1500 is a unique pharmaceutical excipient combining several properties in a single product.
Starch 1500 had multiple functions, such as binder, disintegrant, and flow-aid while having lubricant properties. It is extremely versatile, being effective in a variety of processing methods for solid oral dosage forms, such as direct compression, wet granulation, dry granulation/roller compaction and encapsulation. Starch 1500 is particularly effective with moisture sensitive actives and low dose applications and exhibits synergy, enhancing the functionality of other commonly used excipients in formulations.

The Advantages of Pregelatinized Starch (Starch 1500)
Starch 1500 also has self-lubricating properties, which reduces the need for high levels of lubricants, thus improving mechanical strength and dissolution of the product.

Pregelatinized starches had ability to thicken or gel promptly without the application of a substantial amount of heat necessary with normal starches. However, this ability to rapidly thicken or gel creates problems when these materials are used in dry products to be reconstituted in small portions by the ultimate consumer.

Method to Increase Dissolution Tablet : Pre-formulation and Batch Production Rework

Many factors affected the dissolution tablet :
  • Type, Concentration and solubility of Active Ingredient
  • Type and Concentration of Binder Used
  • Type and Concentration of Fillers Used (soluble vs. insoluble)
  • Type and Concentration of Lubricant Used
  • Type of Dissolution testing Used (Apparatus, Speed, Media)
  • Manufacturing Process (wet granulation vs. compaction vs. direct compression)
  • Hardness of tablet
  • Disintegration time of tablet
  • and many others factors.
Before tablet starts to dissolve, tablet should disintegrate first. So, where tablet begins to disintegrate? Ordinary tablet (immediate release tablet) starts to disintegrate in gastrointestinal tract. GI tract provides sufficient fluid to facilitate disintegration of the dosage form and dissolution of the drug.

Type and Mechanism of Tablet Disintegrant

Disintegrant is an excipient which is added to a tablet or capsule blend to aid in the break up of the compacted mass when it is put into a fluid environment. This is especially important for immediate release products where rapid release of drug substance is required.Disintegrant can be used with products that are wet granulated, dry granulated and direct compression. In wet granulation formulations, the disintegrant is normally effective when incorporated into the granule (intragranularly). It may be more effective if added 50% intragranularly, and 50% extra-granularly.

The simplest way to achieve quick disintegration is to use a superdisintegrant in concert with suitable diluents. Superdisintegrants such as croscarmellose sodium, crospovidone, and sodium starch glycolate are frequently used in tablet formulations to improve the rate and extent of tablet disintegration and thereby increase the rate of drug dissolution.

Paracetamol/Acetaminophen Tablet Formulation Using Cheap and Simple Ingredients with Wet Granulation Method

How to make paracetamol/Acetaminophen tablet commercially?
Paracetamol or also known as Acetaminophen has been very well known as analgesic and antipyretic drug. Actually, this tablets were sold as OTC drug or even prescribed by doctors with high value of prize. Don’t you know, it’s easy to make and all ingredients were easy and cheap to purchased.

It is well known that paracetamol exhibits poor compressibility during compaction, often resulting in weak and unacceptable tablets with a high tendency to cracking and sticking.

The active ingredients, paracetamol, is easy to purchased, so does the other ingredients. The ingredients used to produced paracetamol tablets are:
  1. Paracetamol/Acetaminophen ( Active ingredients)
  2. Maize Starch (Binder)
  3. Croscarmellose (Desintegrant)
  4. Nipagin/Methyl Paraben (Preservative)
  5. Nipasol/Propyl Paraben (Preservative)
  6. Purified Water
  7. Talc (antisticking)
  8. Silicon Dioxide Colloidal (antiadherent)
  9. Magnesium Stearate (Lubricants)

Effervescent Tablet Formulation and Manufacture

What you should know about effervescent forms before formulate and manufacture it? As per revised definition proposed to US FDA, Effervescent tablet is a tablet intended to be dissolved or dispersed in water before administration. Effervescent tablets are uncoated tablets that generally contain acid substances and carbonates or bicarbonates and which react rapidly in the presence of water by releasing carbon dioxide. They are intended to be dissolved or dispersed in water before use. You will find the process of Effervescent Tablet Formulation and Manufacture here.

Many studies have demonstrated that effervescent tablets and powders enhance absorption of a number of active ingredients, such as disulfiram and caffeine. That’s because the carbon dioxide created by the effervescent reaction can induce enhanced active-ingredient permeability due to an alteration of the paracellular pathway. It is theorized that the carbon dioxide alters (widens) the intercellular space between cells, which leads to greater absorption of active ingredients (both hydrophobic and hydrophilic).
