Pharmaceutical excipientsRefers to excipients and additives used in the production of medicines and the preparation of prescriptions; pharmaceutical excipients are substances, other than the active ingredient, that have undergone reasonable safety assessments and are included in drug formulations. In addition to shaping, acting as carriers, and improving stability, pharmaceutical excipients also have important functions such as solubilization, cosolvency, and controlled release. Pharmaceutical excipients are important components that may affect the quality, safety, and effectiveness of drugs.

　　Classification of pharmaceutical excipients:

　　Pharmaceutical excipientsThere are 66 categories based on their functions in formulations. They can be classified by source, function and use, and route of administration.

　　Pharmaceutical excipients by source

　　They can be divided into natural products, semi-natural products, and fully synthetic products.

　　Pharmaceutical excipients by function and use

　　They can be divided into solvents, propellants, solubilizers, cosolvents, emulsifiers, colorants, binders, disintegrants, fillers, lubricants, wetting agents, osmotic pressure regulators, stabilizers, glidants, flavoring agents, preservatives, suspending agents, coating materials, fragrances, anti-caking agents, integrators, penetration enhancers, pH adjusters, buffers, plasticizers, surfactants, foaming agents, antifoaming agents, thickeners, inclusion compounds, humectants, absorbents, diluents, flocculants and anti-flocculants, filter aids, and release retardants.

Pharmaceutical dextrin is a glucose polymer used as a binder and hardener in surgical dressings. Sodium carboxymethyl starch is an etherified starch with properties similar to sodium carboxymethyl cellulose. Sodium carboxymethyl starch is a white or yellow powder, odorless, tasteless, harmless, and hygroscopic. Microcrystalline cellulose is commonly used as an adsorbent, suspending agent, diluent, and disintegrant. Magnesium stearate is a metal derivative, a white, loose powder formed by the combination of magnesium and stearic acid, odorless and tasteless, fine and free of grit, with a faint characteristic aroma. Magnesium stearate is widely used in food, medicine, coatings, plastics, rubber, textiles, etc. Magnesium stearate is a new type of pharmaceutical excipient that can be used as a film-coating material for solid preparations, a thickener for colloidal liquid preparations, and a suspending agent.
