Abstract: The invention provides pharmaceutical compositions containing omega-3 oil and a non-hydrophilic co-solvent that have an increased absorption rate. The pharmaceutical compositions may further contain one or more pharmaceutical organic molecules. The invention further provides kits containing these pharmaceutical compositions, methods for formulating pharmaceutical compositions containing omega-3 oil, and methods for decreasing the likelihood of developing cardiovascular disease, decreasing triglyceride or LDL cholesterol levels, decreasing pain or inflammation, treating diabetes, chronic pulmonary diseases, or irritable bowel syndrome, decreasing symptoms of an autoimmune disease or allergic conditions.

Abstract: The invention provides compositions containing omega-3 oil and at least one anti-inflammatory agent and/or at least one gastrotoxic, nephrotoxic, or hepatotoxic pharmaceutical agent. The invention further provides kits containing these compositions and methods for decreasing pain or inflammation, decreasing the symptoms of an allergic condition, and/or the gastrotoxicity, nephrotoxicity, and hepatotoxicity of a pharmaceutical agent in a subject (e.g., a human) or companion animal requiring the administration of at least one composition containing omega-3 oil. The invention also provides methods for formulating an anti-inflammatory agent to increase its absorption rate requiring the mixing of omega-3 oil with the anti-inflammatory agent and methods of concentrating an omega-3 oil.
