[11] Several types of dessicants are available; the type and quantity need to be matched to the particular drug and package.
PEGylation, by increasing the molecular weight of a molecule, can impart several significant pharmacological advantages over the unmodified form, such as improved drug solubility, reduced dosage frequency with potentially reduced toxicity and without diminished efficacy, extended circulating life, increased drug stability, and enhanced ...
