Comparison of drug forms: characteristics of tablets and capsules.

Drug Forms: Difference Between Tablets and Capsules

When we are talking about drugs, they are often either in the form of tablets or in capsules. The purpose of both is the same — that is, to use drugs in the body — but their composition and use differ.

What is a tablet?

A tablet is a solid form in which a drug is made by pressing it.

It is usually inexpensive, and has the ability to hold a large amount.

A tablet can be made with different coatings to make it easy to swallow or to give a delayed effect.

What is a capsule?

A capsule is an open, hollow, or shaped substance.

Inside it, the drug is found in powder, or granular form.

The main benefit of a capsule is that it hides the smell and taste of the drug, and preserves the drug.

Why use capsules?

1. To hide the taste and smell

Some drugs are very dry or smelly. If they are given in the form of tablets, it becomes difficult for the patient. The capsule closes the medicine in the opening, which makes it tasteless.

2. Liquid or powder medicines

Some medicines are in the form of powder, it is not possible to put them exactly in a tablet. For this, they are closed so that they can be used easily.

3. To affect a specific place

Some medicines get damaged or do not give effect if they are opened. The capsule is made in such a way that they open in the intestines, so that the medicine affects the right place.

4. To absorb slowly

Some medicines should be absorbed slowly in the body so that their effect lasts for a long time. For this purpose, the use of slow capsules is indicated.

Conclusion

Both tablets and capsules are important in their own right. Pharmaceutical companies decide whether to make a tablet or capsule by looking at the definition, quantity, and effect of the medicine.

If the medicine is viscous or smelly → capsules are better.

If the medicine is in high quantity → tablets are more

If the medicine is to be used in a specific place → capsules are used.

If the medicine is to have a long-lasting effect → slow capsules are best.

Finally, the choice of the form of the medicine is made by keeping in mind the patient's condition and the effect of the medicine. The reason is that some medicines come in tablets and some in capsules.
