Whether a company is manufacturing pharmaceutical dosage forms or cosmetics, empty capsule shells are increasingly being used for clinical research. The demand for these capsule shells is also increasing.
Gelatin is a commonly used substance for capsule making. Usually, gelatin capsules are made from pork or beef. Gelatin capsules are easy to manufacture and can be produced in a cost effective manner. However, gelatin capsules can be prone to bacterial contamination. Therefore, it is important to store them in a cool, ventilated place.
Vegetarian capsules are available. They may be made from a variety of materials. Some capsules are made from modified starches, hypromellose, or other plant gums. Others are made from lac resin, honey, or heparin.
Capsules may be coated with gelatin, glycerin, or sugars. Glycerin is often used as a processing aid, and may be derived from vegetable sources. Other chemicals, such as fat-derived chemicals, may be derived from animal sources.
Capsules are mainly used for oral consumption. They can be stored for several months. However, the capsule should be sterile and sealed before use. They should also be stored away from sunlight and heat.
Capsules are used to deliver drugs at a much earlier time than tablets. They are also more effective because they are more compact.
Therefore, they can be used as a substitute for tablets.
Gelatin is also used in liquid supplements. In these products, a mixture of propylene glycol and water is often used as an alternative to ethyl alcohol.
