Types Of Tablets
Compressed Tablet
The compressed tablets are prepared by the compression method. This is the simplest method to prepare the tablet. These tablets are prepared with granules or powdered materials. These tablets are either compressed directly in the compression machine or combined with additives or diluents, binders, disintegrants, colorants, lubricants, and flavoring agents if any. There is not required any special type of coating in the manufacturing of compressed tablets.Sugar-Coated Tablets
Sugar-coated tablets are also a type of compressed tablet with a coating surrounding the tablet called a sugar-coated tablet. These coatings can be or can not be colored to mask (reduce) the unpleasant (bitter) taste and odor (bad smell) of the tablets. Sugar-coated tablets are very popular due to the patient's acceptance because of their sweet taste.Film-Coated Tablets
The film-coated tablets are also a type of compressed tablets that are covered with a thin layer of water-soluble materials. Many film-forming substances are used like different types of polymers. The film coating has some characteristics over film coating as it reduces the time of the coating process.Enteric-Coated Tablet
The Enteric-coated tablet is also a compressed tablet. These tablets are having the property that when a patient takes an enteric-coated tablet then it's coting dissolved in the stomach where gastric acid is present and disintegrates into the intestine to produce the desired action. The enteric-coated tablets are used when there is a delayed release of medicaments required.Multiple Compressed Tablets
Multiple compressed tablets are the type of compressed tablets prepared by more than one compression method. The requirements of these types of tablets occur when two or more active ingredients are used in one tablet and they are not compatible with each other means due to the stability of active ingredients.Effervescent Tablets
Effervescent tablets are the types of tablets that contain sodium bicarbonate which acts as a disintegrating agent by reacting with water to produce the carbon dioxide gases called effervescent. Effervescent tablets contains the sodium bicarbonate and tartaric acid or citric acid.Buccal and Sublingual Tablets
The Buccal and Sublingual tablets are prepared for inserting the drug into the space between the lip and gum which is the Buccal cavity in the mouth. The size of these tablets is small, flat, and oval. These types of tablets are prepared by hard compression so, these tablets dissolve in the buccal cavity very slowly.Molded Tablets or Tablet Triturates
These tablets are prepared with the help of triturate mold which gives the desired shape of cut sections of a cylinder. Generally, these tablets are prepared from moist materials. The molded tablets are completely and very rapidly soluble. The main problem that occurs while preparing these tablets is that it is very difficult to find completely water-soluble lubricant for these types of tablets.Dispensing Tablets
Dispensing tablets provide a sufficient amount of potent drugs that can be mixed easily into powders and liquids.Hypodermic Tablets
Hypodermic tablets are soft, readily soluble tablets and were originally used for the preparation of solutions to be injected.Conclusion
