Abstract
The disclosed invention is drawn to pharmaceutical tablets that provide delivery of active agents having at least three oxygen-containing groups, as well as a second active ingredient. Non-limiting examples of three oxygen-containing group active agents include guaifenesin, codeine, hydrocodone, and their pharmaceutically acceptable salts. In one embodiment, a pharmaceutical tablet for oral administration once every 12 hours is provided. The tablet includes a first active agent that is a tri-oxy active agent, a second active agent, and a release rate controlling non-ionic oxyl-containing hydrophilic polymer. The total oxyl content of the hydrophilic polymer in the tablet is about 4×10moles to about 2.0×10moles.
