A capsule is a small container or envelope, typically made of gelatin, used for storing or administering drugs or other substances. Capsules are commonly used in the pharmaceutical industry as a means of delivering medication in a convenient and easily digestible form.


The use of capsules for medicinal purposes dates back to ancient times. The ancient Greeks and Egyptians were known to have used capsules made from animal hides to store and administer various substances. However, it wasn't until the 19th century that the modern gelatin capsule was developed, revolutionizing the way medications were delivered.

Types of Capsules

There are two main types of capsules: hard capsules and soft capsules. Hard capsules are typically made from two pieces that fit together to enclose the medication, while soft capsules are made from a single piece of gelatin that is filled with liquid or semi-solid medication. Both types of capsules have their own advantages and are used for different purposes depending on the medication being delivered.


Capsules are commonly used in the pharmaceutical industry for a variety of purposes. They are often used to deliver medications that are sensitive to light or air, as the gelatin casing provides a protective barrier. Capsules are also used to deliver medications that have a strong or unpleasant taste, as the casing helps to mask the flavor. Additionally, capsules are often used to deliver medications that need to be released slowly over time, as the gelatin casing can be designed to dissolve at a specific rate.


In conclusion, capsules are a versatile and convenient means of delivering medication. Whether in the form of hard capsules or soft capsules, these small containers play a crucial role in the pharmaceutical industry and have revolutionized the way medications are administered. With their ability to protect sensitive medications, mask unpleasant tastes, and control the release of drugs, capsules will continue to be an important tool in the field of medicine for years to come.
