Therapeutic Indication

Avidro Tablet 0.5 mg is indicated for:

• Prophylactic treatment of migraine

• Prevention of recurrent migraine attacks

It is not effective for the relief of an acute migraine attack and should be used only for preventive purposes as directed by a physician.

Mechanism of Action

Pizotifen acts mainly by blocking serotonin (5-HT₂) receptors, which play an important role in migraine pathophysiology. By inhibiting serotonin-mediated vascular and neurological changes, Avidro:

• Lowers the likelihood of migraine attacks

Its mild antihistaminic and anticholinergic effects may further support its preventive action.
