Ever since their inception, capsules have been considered by most consumers to the most effective method of taking medication. Over the years, many drug-manufacturers such as Over-The-Counter analgesics developed the "capsule-shaped tablet" or "Caplet" to emphasize the effectiveness of their product, as well as to portray a positive association with more efficiently manufactured tablet pills.

Encapsulation refers to the technique of inserting certain drugs into capsules that allow them to be taken orally. Visit tesequipmentsupplier to find the best encapsulator machines.

Encapsulation is useful when a prescribed drug needs to be mixed with oil or other fluids to aid absorption into the body. Because of this, many users prefer capsules – easier to swallow and more effective.


There are two main categories of capsules:

Hard capsule: The most common hard capsule consists of a hard shell of two parts that are stuck together and filled with a prescribed medication. This formulation is usually more suitable for dry and powdered drugs.

Soft capsules: Soft capsules are made whole and are mainly intended for active ingredients that are soluble in oil or other liquids.


The capsules contain the drug, usually in a small gelatin container that is easily digested by the body. Many drug manufacturers use capsules because of the nature of some drugs that make them difficult to produce in tablet form. Tablet manufacturing requires a suitable binder which allows the drug to form a solid without, however, adversely affecting its properties or bioavailability.
