Abstract
The invention relates to a topical suspension formulation that includes a tetracycline, a liquid medium and a polymeric gelling agent. The tetracycline may be in the form of its pharmaceutically acceptable salts, hydrates, or polymorphs and is in a suspended form within the formulation. The liquid medium is selected such that it does not dissolve or substantially minimally dissolves the tetracycline. The gelling agent is a polymeric hydrocarbon gelling agent. Preferably, the tetracycline has a particle size of less than or equal to about 20 microns.
