Excipients Are Almost Always Used in Drugs

What are excipients? For example, the manual of a certain brand of ibuprofen sustained-release capsules shows that in addition to ibuprofen, its ingredients also include excipients such as lactose, starch, ethyl cellulose, and 95% ethanol; For example, the manual of a certain brand of loratadine tablets shows that in addition to loratadine, its ingredients also include corn starch, sucrose, microcrystalline cellulose, hydroxypropyl methylcellulose, sodium carboxymethyl starch, magnesium stearate, and other auxiliary materials.

These auxiliary materials are not used to "adulterate and deceive", let alone to "deceive and deceive". Its function is not just to shape, package, or improve taste, on the contrary, medicinal excipients are an important guarantee of the effectiveness of raw materials. Excellent medicinal excipients can not only enhance the stability of active ingredients, extend the shelf life of drugs, but also better regulate the dissolution or release behavior of active ingredients in vitro and in vivo. It is no exaggeration to say that the importance of medicinal excipients is no less than the effective ingredients of drugs.
