Parenteral drug products are sterile formulations intended for injection, infusion, or implantation. They must be free from pyrogens and particulates, stable, and isotonic. These preparations include injections, infusions, powders, and implants, formulated using aqueous or non-aqueous vehicles with suitable additives like buffers, antioxidants, and antimicrobial agents.
Pharmaceutical liquid dosage forms contain active drugs dissolved or suspended in solvents, offering flexible dosing and rapid absorption. They are ideal for patients who struggle with solids. Classified into monophasic (solutions) and biphasic forms (suspensions, emulsions), they ensure effective drug delivery and easy administration across various routes.
Organoleptic agents like colouring, flavouring, and sweetening substances are added to pharmaceutical products to improve their sensory appeal and patient acceptability without affecting therapeutic efficacy
