Background of Capsule Excipients

Capsules have a very long history. The first capsules were created in Egypt as early as 1500 BC. Capsules are normally divided into hard capsules and soft capsules. Hard capsules, also known as hollow capsules, are composed of two halves: a cap and a body, while the soft capsules are processed into products from film-forming materials and contents at the same time, which is primarily used for oils and for active ingredients that are dissolved or suspended in oil. Besides, according to raw materials, hollow capsules generally include: gelatin hollow capsules and plant-derived hollow capsules (hydroxypropyl methylcellulose capsule, HPMC capsule).

Diluents, lubricants, glidants, disintegrants, wetting agents, adhesives, etc. are the principal excipients for capsules. The capsule can achieve the desired pharmacokinetic parameters and lower manufacturing costs with the help of the right excipients. It makes pharmaceutical product manufacturing easier and ultimately helps the drug's physiological absorption.

Classification of Capsule Excipients

(1) Diluents: Improve the physical properties of the contents and increase the volume, with certain compressibility. Commonly used diluents are mannitol, microcrystalline cellulose, lactose, pregelatinized starch 1500, corn starch, etc.

(2) Lubricants: Prevent the adhesion of powder to metal materials. Common materials include magnesium stearate, glyceryl monostearate, stearic acid, talc, etc.

(3) Glidants: Improve the fluidity of the contents. Commonly used glidants are micro-silica gel and talcum powder.

(4) Disintegrants: Ensure the disintegration of the contents. Common disintegrants include crosslinked cellulose, corn starch, crospovidone, pregelatinized starch 1500, etc.

(5) Wetting agents: Increase the wettability of the drug and the dissolution medium to ensure the efficacy of the preparation. Polysorbate 80, sodium lauryl sulfate, etc.

(6) Adhesives: The adhesive binds the drug powder together at the time of granulation, such as starch slurry, CMC-Na, etc.
