Patent Claims:	1. A pharmaceutical composition comprising a capsule filled with a composition comprising one or more pharmaceutically active agent wherein said pharmaceutically active agent is selected from the group consisting of said agents wherein at least one of said agents having at least one acid moiety, and at least one of said agents having at least one ester group or other chemically active moiety in which the terminal moiety to said ester group or other chemically active moiety is hydrolyzed or otherwise removed in situ or in vivo forming at least one acid moiety; and wherein said pharmaceutically active agent is soluble in acid at a ratio of about 3:1 (acid to solute) to about 10,000:1 (acid to solute) or a pharmaceutically acceptable salt thereof; at least one dispersing agent selected from the group consisting of polymer-based dispersing agents and carbohydrate-based dispersing agents, wherein the ratio of said one or more pharmaceutically active agent to said at least one polymer-based dispersing agent is from about 3:1 (w/w) to about 1:50 (w/w) and wherein the ratio of said one or more pharmaceutically active agent to said at least one carbohydrate-based dispersing agent is from about 3:1 (w/w) to about 1:20 (w/w); and at least one solubilizing agent; and, optionally, at least one surfactant; and further optionally, at least one plasticizing agent; and wherein said capsule is optionally coated. 2. A pharmaceutical composition according to claim 1 wherein said capsule is selected from the group consisting of soft gelatin capsules and hard gelatin capsules. 3. A pharmaceutical composition comprising a capsule filled with a composition according to claim 1, wherein: said at least one dispersing agent is said at least one polymer-based dispersing agent; said at least one solubilizing agent has a concentration ranging from about zero percent to about 99 percent (w/w) of the total composition; and, optionally, said at least one optional surfactant has a concentration ranging from about zero percent to about 10 percent (w/w) of the total composition; said at least one optional plasticizing agent has a concentration ranging from about zero percent to about 25 percent (w/w) of the total composition; and wherein said capsule is optionally coated. 4. A pharmaceutical composition according to claim 3 wherein said capsule is selected from the group consisting of soft gelatin capsules and hard gelatin capsules. 5. A pharmaceutical composition comprising a capsule filled with a composition according to claim 1, wherein: said at least one dispersing agent is said at least one carbohydrate-based dispersing agent; said at least one solubilizing agent has a concentration ranging from about zero percent to about 99 percent (w/w) of the total composition; and, optionally, said at least one optional surfactant has a concentration ranging from about zero percent to about 10 percent (w/w) of the total composition; said at least one optional plasticizing agent has a concentration ranging from about zero percent to about 25 percent (w/w) of the total composition; and wherein said capsule is optionally coated. 6. A pharmaceutical composition according to claim 5 wherein said capsule is selected from the group consisting of soft gelatin capsules and hard gelatin capsules. 7. A pharmaceutical composition according to claim 3 wherein said one or more pharmaceutically active agent is selected from the group consisting of non-steroidal anti-inflammatory drugs, quinapril, fluvastatin, lovastatin, pravastatin, cervistatin, atorvastin, simvastatin, fexofenadine, cromolyn, omeprazole, gemfibrozil, ciprofibrate, ciprofloxacin, lomefloxacin, ofloxacin, carbidopa, levodopa, retinoic acid, carboprost, penicillins, beta lactams, cephalosporins, liothryonine and probenecid. 8. A pharmaceutical composition according to claim 5 wherein said one or more pharmaceutically active agent is selected from the group consisting of non-steroidal anti-inflammatory drugs, quinapril, fluvastatin, lovastatin, pravastatin, cervistatin, atorvastin, simvastatin, fexofenadine, cromolyn, omeprazole, gemfibrozil, ciprofibrate, ciprofloxacin, lomefloxacin, ofloxacin, carbidopa, levodopa, retinoic acid, carboprost, penicillins, beta lactams, cephalosporins, liothryonine and probenecid.
