Concurrently, the harmful metabolites of microorganisms and several pathogenic microorganisms may cause adverse reactions or secondary bacterial infections to sufferers. For that reason, microbial limit testing for non-sterile drug products has become the critical measures to make sure the quality, basic safety and performance of medication.

For drug commodities, the two security and effectiveness are very important. To the one hand, drug protection is set by whether the chemical composition and written content with the drug are Protected, and Conversely, drug basic safety is decided by whether or not the drug is contaminated by microorganisms. There are many types of microorganisms. Right after contaminating drugs, they may decompose the powerful ingredients of prescription drugs, resulting in decreased or dropped efficacy.
