Cyclosporins are cyclic polypeptide macrolides that were originally derived from the soil fungus Tolypocladium inflatum. Cyclosporine (also known as cyclosporine A) was discovered by Sandoz and developed for the tretment of immune disorders. The drug was approved by FDA for such diseases as Rheumatoid Arthritis, Psoriasis (Neoral), Keratoconjunctivitis sicca (Restasis) and prevention of transplant rejections (Neoral and Sandimmune). Cyclosporine’s primary immunosuppressive mechanism of action is inhibition of T-lymphocyte function. Upon administration cyclosporine binds to cyclophilin A and thus inhibits calcineurin, leading to immune system suppression.
Zinc monocarbonate (Zinc Carbonate) is an inorganic salt. In the United States, Zinc Carbonate may be used as an active ingredient in OTC drug products. When used as an active drug ingredient, the established name is Zinc Carbonate. Zinc monocarbonate is generally recognized as safe by FDA. It is used as skin protectant active ingredient. Zinc carbonate was found to retard the degradation of some poly(lactide-co-glycolide) (PLG) microspheres in vivo and in vitro. Adding Zinc Carbonate is essential during the preparation of PLGA microspheres. It can remarkably improve the stability of drugs in the acid microenvironment inside PLGA microspheres.
