Documented Uses

• Pharmaceuticals -> Animal Drugs -> Approved in Taiwan
• In the information for tolfenamic acid, it is stated that this drug, being an NSAID, is effective in treating the pain associated with the acute attack of migraines in adults.
• Compounds capable of relieving pain without the loss of CONSCIOUSNESS.
• Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.
• A class of drugs that act by selective inhibition of calcium influx through cellular membranes.
• Compounds that inhibit the action of prostaglandins.
