To improve physico-chemical properties of an active pharmaceutical ingredient (API) at its preformulation stage, myriad of excipients having defined functional roles like solubility enhancement by co-solvent, micells formation and complexation, intestinal permeability enhancement through the inhibition of efflux transport mechanisms, stability-improvement using pH adjustment, cryo-and lyo-protectants, etc are incorporated into a dosage form containing the API. Although considered primarily as inactive materials, the excipient(s) may react with the API resulting in the development of a…mehr

Produktbeschreibung
To improve physico-chemical properties of an active pharmaceutical ingredient (API) at its preformulation stage, myriad of excipients having defined functional roles like solubility enhancement by co-solvent, micells formation and complexation, intestinal permeability enhancement through the inhibition of efflux transport mechanisms, stability-improvement using pH adjustment, cryo-and lyo-protectants, etc are incorporated into a dosage form containing the API. Although considered primarily as inactive materials, the excipient(s) may react with the API resulting in the development of a detrimental or beneficial substance within the API-loaded dosage form itself. If detrimental substances are formed, then, the issue of API-excipient incompatibility will come up and demand the reformulation of the API, which is costly and time-consuming. This book surveys a comprehensive list of published examples of API-excipient incompatibility relevant to currently or previously marketed drugs. With this coverage, this book also provides first-hand information on the multicomponent nature and complexity of the excipients to the formulation scientist.
Autorenporträt
Prof. (Dr.) Tamilvanan and Mrs. Syed Nazrin Ruhina Rahman are working on the development of single or dual drug-loaded colloidal dispersion eyedrops for managing dry eye syndrome. They have also created a bi-compartmental structure within the dispersed phase of colloidal dispersion eyedrops to entrap two different drugs.
