Effects of deprenyl or propargylamine compounds (MAO inhibitors) and novel compositions comprising at least one MAO inhibitor and at least one antiinflammatory agent such as nonsteroidal antiinflammatory drugs (NSAIDS), steroids, acetaminophen (COX-3 inhibitors), 5-lipoxygenase inhibitors, leukotriene receptor antagonists, leukotriene A4 hydrolase inhibitors, antihistaminics, histamine 2 receptor antagonists, phosphodiesterase-4 antagonists, cytokine antagonists, CD44 antagonists, antineoplastic agents, 3-hydroxy-3-methylglutaryl coenzyme A inhibitors (statins), estrogens, androgens, antiplatelet agents, antidepressants, Helicobacter pylori inhibitors, proton pump inhibitors, thiazolidinediones, dual-action compounds, combinations of these drugs with other agents, derivatives and metabolites of synthetic and natural antiinflammatory agents. The compounds and compositions protect against gastrointestinal, renal and other toxicities induced by antiinflammatory agents, and enhance the beneficial effects of these drugs. Effects of MAO inhibitors such as 1-deprenyl co-administered with antiinflammatory drugs or chemically attached to antniinflammatory drugs are disclosed. Therapeutic methods of using MAO inhibitors and antiinflammatory drugs for the prevention and treatment of inflammatory disorders, pain, fever, cancer, gastrointestinal lesions, and a variety of cardiac, cerebral and peripheral disorders are disclosed.
