Decreasing the drinking water content has Traditionally been a effortless technique to shield foods from microbial spoilage. Illustrations in which the obtainable dampness is reduced are dried fruits, syrups, and pickled meats and vegetables. Low water activity will likely avoid microbial advancement inside pharmaceutical preparations, see also Sect.
Simultaneously, the harmful metabolites of microorganisms plus some pathogenic microorganisms might also trigger adverse reactions or secondary bacterial infections to people. Therefore, microbial limit testing for non-sterile drug products is among the critical measures to ensure the standard, safety and effectiveness of medication.
Mould spores could induce significant concerns inside the production of pharmaceutical preparations due to the fact they survive desiccation and may be transported by means of air, staff or content movement into products.
Quite a few procedures are getting used or in enhancement to scale back infectivity of blood products, including solvent-detergent processing of plasma and nucleic acid cross-linking by using photochemical reactions with methylene blue, riboflavin, psoralen and alkylating brokers. Numerous options exist to further more strengthen blood security via advancements in infectious condition screening and pathogen inactivation solutions [21, 22].
