Abstract

The present invention relates to extended or controlled release pharmaceutical compositions of 7-dimethylamino-6-deoxy-6-demethyltetracycline (minocycline) or non-toxic acid addition salts thereof. More particularly, it relates to a once-a-day delivery system for minocycline that maintains its therapeutic plasma concentrations in a patient for twenty-four hours. The extended release pharmaceutical composition includes a mixture of 7-dimethylamino-6-deoxy-6-demethyltetracycline (minocycline), or a non-toxic acid addition salt thereof, and two or more hydrophilic matrix forming polymers configured to form a matrix upon administration. Each hydrophilic matrix forming polymer differs at least in viscosity.
