Capsule (pharmacy)
A Capsule (pronounced: /ˈkæpsjuːl/, from Latin capsula, a small box) is a type of dosage form used in pharmacy for the delivery of medications.
Definition
A capsule is a small, cylindrical container made from gelatin or a similar substance, which is digestible and contains a dose of medication. The medication can be in the form of a powder, a liquid, or a granule.
Types of Capsules
There are two main types of capsules used in pharmacy: hard capsules and soft capsules.
- Hard Capsules: These are made from two pieces that fit together. They are typically filled with dry, powdered ingredients.
- Soft Capsules: These are a single piece and are usually filled with liquids or oils.
Advantages of Capsules
Capsules have several advantages as a dosage form. They can mask the taste and smell of unpleasant drugs, they are easy to swallow, and they can deliver a precise dose of medication.
Disadvantages of Capsules
The main disadvantage of capsules is that they can be difficult to swallow for some people, particularly children and the elderly. They also cannot be used for drugs that are unstable in the presence of moisture, as the gelatin shell can absorb moisture from the air.
