Diclofenac is effective for relief from migraine. It is a very common drug used in day-to-day routine by migraine patients. It is also available widely across the entire country and around the world.
Diclofenac is a phenylacetic acid derivative that has anti-inflammatory, antipyretic, and analgesic properties through inhibition of COX-1 and COX-2 activity and prostaglandin synthesis. Diclofenac is a potent COX inhibitor, with activity 3–1000 times greater than other NSAIDs. These actions relieve migraine (Gan, T.J., 2010. Diclofenac: an update on its mechanism of action).
Scientific study for Treatment of Acute Migraine Attack With Diclofenac
In a double-blind placebo-controlled experiment comprising 86 migraine patients, the efficacy of diclofenac sodium, a powerful prostaglandin inhibitor, was examined in patients with acute migraine attacks.
Forty-six patients with acute migraine attacks were given a 75 mg diclofenac sodium intramuscular injection, while another forty individuals were given a paracetamol intramuscular injection.
The diclofenac sodium group experienced partial or complete relief of pain and other symptoms of an acute migraine episode within 10 minutes of treatment, while the paracetamol group experienced relief within 32 minutes.
In 40 patients (88 percent), complete alleviation of the attack was achieved within 30 minutes after diclofenac sodium, compared to 7 patients (17.5 percent) in the paracetamol group. Side effects were uncommon and minor.
In conclusion, diclofenac sodium given intramuscularly is a highly effective treatment for acute migraine attacks (McNeely, W. and Goa, K.L., 1999. Diclofenac-potassium in migraine).
