Abstract

The present application relates to a method of orally administering once daily tablet of minocycline to a subject in need thereof, wherein said tablet is substantially free of lactose. The present application also relates to processes for preparing said once daily tablet of minocycline that provides reduced stock keeping units with improved inventory by supplying multiple doses of minocycline in single tablet.

Description

RELATED APPLICATIONS[0001]This application claims priority from U.S. patent application Ser. No. 15 / 093,673, filed Apr. 7, 2016 and Indian Provisional Application No. 1815 / CHE / 2015, filed Apr. 7, 2015.TECHNICAL FIELD[0002]The present invention relates to a composition comprising minocycline, a method of orally administering a once daily tablet of minocycline to a subject in need thereof, and a processes for preparing the tablet thereof.BACKGROUND[0003]Minocycline is a semi synthetic derivative of tetracycline, [4S-(4α,4aα,5aα,12aα)]-4,7-Bis(dimethylamino)-1,4,4a,5,5a,6,11,12a-octahydro-3,10,12,12a-tetrahydroxy-1,11-dioxo-2-naphthacenecarboxamide. The Orange Book of USFDA lists various dosage forms of minocycline hydrochloride such as immediate release (IR) tablets, capsules, and extended release (ER) tablets, indicated for the treatment of only inflammatory lesions of non-nodular moderate to severe acne vulgaris in subjects 12 years of age and older. Intravenous injection is availab...
