This doc discusses techniques for injectable managed release formulations. It begins by defining controlled launch as the supply of the drug at a predetermined level to maintain optimum concentrations over a prolonged period. It then discusses various methods such as dissolution controlled, adsorption variety depots, encapsulation techniques, and esterification type depots.
This doc delivers an summary of sterile dosage sorts for parenteral and ophthalmic drug administration. It discusses various routes of parenteral administration and important components of parenteral goods, together with vehicles, stabilizers, buffers, and antimicrobial agents.
