Documented Uses

• Animal Drugs -> FDA Approved Animal Drug Products (Green Book) -> Active Ingredients
• Breast Feeding; Lactation; Milk, Human; Analgesic Agents; Anti-inflammatory Agents, Nonsteroidal
• Dipyrone (Class: Analgesics, Added Date: 10-1998)
• 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.
• Drugs that are used to reduce body temperature in fever.
• N02B - Other analgesics and antipyretics
