Tolfi tablet: Each tablet contains Tolfenamic acid BP 200 mg.
Tolfenamic acid (N-(2-methyl-3-chlorophenyl) anthranilic acid) belongs to the fenamate group and is a potent inhibitor of cyclo-oxygenase enzyme, thus inhibits the synthesis of important inflammatory mediators such as thromboxane (Tx) B2 and prostaglandin (PG) E2. Prostaglandins are responsible for causing swelling, pain and inflammation associated with these conditions. It acts not only by inhibiting prostaglandin synthesis, but it also has a direct antagonistic action on its receptors.
Tolfi is used specifically for relieving the pain of migraine headaches and also recommended for use as an analgesic in post-operative pain, and fever.
