A hard capsule is a type of pharmaceutical dosage form that consists of two pieces: a body and a cap. These capsules are typically made from gelatin, which allows them to dissolve easily in the stomach. Hard capsules are commonly used to contain powdered or granular substances, making them a popular choice for delivering medications and dietary supplements. The primary advantage of hard capsules is their ability to mask the taste of the contents and provide a convenient way to swallow medication. They can also be filled with a variety of substances, including herbal extracts, vitamins, and prescription drugs, making them versatile for different applications in the healthcare industry.
