Capsules are solid dosage forms with hard or soft shells. They come in a variety of shapes and sizes and contain a single dose of one or more active ingredients. They are used for oral administration.

    Capsules can be divided into solid drugs and liquid drugs according to the physical state (phase) of the filled drug. Capsules can be divided into hard gelatin capsules, soft gelatin capsules, HPMC capsules, pullulan capsules, starch capsules, enteric-coated capsules, metal capsules, etc.

    A hard gelatin capsule is a capsule mainly composed of gelatin and purified water. Some colored hard gelatin capsules also contain small amounts of titanium dioxide and colorants.

    The main component of gelatin hard capsules is gelatin, which is harmless, inexpensive, edible, degradable, and easy-to-store and use protein product.

    The composition of soft gelatin capsules is similar to that of hard gelatin capsules, but the water ratio is different. Plasticizers are often added to maintain capsule elasticity and stability, including glycerin, sorbitol, and the like. Can be filled with liquid. Most of the features of soft capsules are similar to hard capsules.

    HPMC Capsule is mainly composed of HPMC and purified water. HPMC is the abbreviation of hydroxypropyl methylcellulose, which is a kind of cellulose obtained by hydrolysis of plants. It is obtained by etherification.

    The main components of amylopectin capsules are amylopectin and purified water. Pullulan is a water-soluble mucopolysaccharide, a well-established food additive, also included in JECFA. It has become an ideal raw material for capsule production due to its excellent film-forming properties and can replace animal gelatin to make pure natural vegetarian hollow capsules. In addition, it has extremely low moisture content and good toughness. Pullulan capsules can be filled with water-sensitive medications.

    To be precise, enteric-coated capsules do not belong to a certain category of capsules. They are made by applying an enteric coating to other common capsules or other processing methods. The main characteristics of enteric-coated capsules are related to the raw capsules used. Enteric-coated capsules are mainly to meet the needs for the intestinal release of drugs. Because some drugs may have a strong irritating effect on the stomach, some drugs may be destroyed by stomach acid, or some drugs may work better in the intestines.
