Abstract:
Disclosed herein is a novel process for preparation of ophthalmic suspensions of Carbonic anhydrase inhibitor such as Brinzolamide. Said process is characterized in that it does not involve autoclaving of the active ingredient Brinzolamide. The invention further discloses ophthalmic suspensions comprising Brinzolamide and combination of Brinzolamide and beta-blocker prepared by the novel process.

Abstract:
The present invention discloses a novel process for purification of trans-4-methyl cyclohexylamine HC1 and 4-[2-(3-Ethyl-4-methyl-2-carbonyl pyrrolidine amido) ethyl] benzene sulfonamide used in the synthesis of 3-Ethyl-2,5-dihydro-4-methyl-N-[2-[4-[[[[(trans-4-methyl cyclohexyl)amino]carbonyl]amino]sulfonyl]phenyl]ethyl]-2-oxo-1H-pyrrole-1-carboxamide(I), popularly known as Glimepiride. The present invention also discloses a novel purification of Glimepiride Form I (I), having the undesired cis isomer below 0.15%. Glimepiride (I) is useful in the treatment of diabetes mellitus.
Abstract:
The present invention relates to a commercial process for purification of human Growth hormone obtained by DNA recombinant technique using hydrophobic interactive chromatography, efficient to separate clipped molecules of human growth hormone present as an impurity arising due to clipping positions present on the megamolecule of human growth hormone from the target human growth hormone molecule using a phenyl column, mixture of aqueous buffers and organic solvents as an eluant, followed by desalting, lypholization and the invention also relates to the process wherein the elution of clipped molecules of human growth hormone precedes the elution of target human growth hormone to obtain hGH of purity > 99.5%.
