Abstract: A stable pharmaceutical composition comprising about 1 wt. % to about 80 wt. % of an ACE inhibitor or a pharmaceutical acceptable salt thereof, about 1 wt. % to about 70 wt. % of an alkali or alkaline earth metal carbonate, and about 1 wt. % to about 80 wt. % of hydroxypropyl cellulose, wherein the ACE inhibitor is selected from the group consisting of quinapril, enalapril, spirapril, ramipril, perindopril, indolapril, lisinopril, alacepril, trandolapril, benazapril, libenzapril, delapril, cilazapril and combinations thereof; wherein the formation of an internal cyclization product, and/or ester hydrolysis product, and/or oxidation product, has been reduced or eliminated, and the weight percents are based on the total weight of the pharmaceutical composition.

Abstract: The present invention is a method of achieving fast onset of pain relief for acute pain in a patient in need thereof comprising orally administering a unitary formulation (or oral dosage form) containing an effective analgesic amount of (a) oxycodone or a pharmaceutically acceptable salt thereof and (b) ibuprofen or a pharmaceutically acceptable salt thereof. Preferably, the unitary formulation contains (a) oxycodone or a pharmaceutically acceptable salt thereof and (b) ibuprofen or a pharmaceutically acceptable salt thereof at a weight ratio of from about 1:20 to about 1:100 and more preferably about 1:40 to about 1:80, based on the weights of molar equivalents of oxycodone hydrochloride and ibuprofen, respectively. Preferably, an amount of oxycodone and ibuprofen effective to provide partial or complete pain relief within 30 minutes is administered. More preferably, the amount is sufficient to provide partial or complete pain relief within 25 minutes.

Abstract: The present invention provides a pharmaceutical composition having enhanced solubility comprising a drug and polyethylene glycol, wherein the ratio of polyethylene glycol to drug by weight is from about 0.2:1 to about 10:1, and the polyethylene glycol has a melting point of at least 37° C. The pharmaceutical compositions exhibit rapid dissolution upon contact with physiological solvents, such as water, saliva or gastrointestinal fluids.
