Silica gel powder has many applications in the pharmaceutical field, mainly including the following aspects:
Drug carrier: Silica gel powder can be used as a carrier for drugs to make sustained-release and controlled-release drugs, helping the drug to be released stably in the body and prolong the duration of drug effect.
Adsorbent: Silica gel powder is widely used in the purification and separation of drugs due to its good adsorption properties. For example, in the process of drug extraction, silica gel can adsorb impurities and help purify the active ingredients.
Anti-caking agent: In some powder dosage forms of drugs, silica gel powder is used as an anti-caking agent to prevent the drug ingredients from agglomerating during storage and use, and maintain the fluidity and uniformity of the drug.
Filler: Silica gel powder is sometimes also used as a filler for drugs, used to prepare solid preparations such as tablets and capsules, to help form a suitable dosage form.
Moisture adsorption: Silica gel has hygroscopic properties, which can effectively prevent drugs from deteriorating due to moisture, and is widely used in the packaging and storage of drugs.
In general, silica gel powder plays a role in improving the quality of drugs, extending the shelf life of drugs and improving the performance of drugs during drug preparation, storage and transportation.
