ABSTRACT:
Embodiments of the invention generally provide pharmaceutical drug compositions, methods of preparing oral drug compositions, such as extended release dosage compositions, and methods for treating infection. More particularly, the invention relates to formulations containing a drug and a carrier material. In one aspect, the invention provides a pharmaceutical formulation including a therapeutically active agent, from about 0.1% to about 4.9% by weight of a pharmaceutically acceptable polymer, and from about 0.1% to about 30% by weight of a pharmaceutically acceptable acid, wherein the pharmaceutical composition have a zero order release profile of the therapeutically active agent. In another aspect, the invention provides methods for preparing and administering a pharmaceutical antibiotic composition in oral dosage form, such as a tablet.
