Frovatriptan succinate hydrate ((R)-Frovatriptan succinate hydrate) is a potent, high affinity, selective and orally active5-HT_1B(pK₅₀of 8.2) and5-HT_1Dreceptoragonist. Frovatriptan succinate hydrate exhibits >10-fold selectivity for5-HT_1Band5-HT_1Dover 5-HT_1A, 5-HT_1F, and 5-HT₇and >1000-fold selectivity over other 5-HT, dopamine, histamine H₁, and α1-adrenoceptor. Frovatriptan succinate hydrate has the potential for migraine research^[1][2].

Cerebral vasodilatation and neurogenic inflammation are considered to be prime movers in the pathogenesis of migraine. Activation of 5-HT_1Breverses cerebral vasodilatation and activation of 5-HT_1Dprevents neurogenic inflammation. Frovatriptan has a high affinity for 5-HT_1Band 5-HT_1Dreceptors and a moderate affinity for the 5-HT_1Aand 5-HT_1Freceptors subtypes. Frovatriptan has a moderate affinity for the 5-HT₇receptors, an action associated with coronary artery relaxation in the dog^[1].

Oral bioavailability of Frovatriptan is 22%-30% and is not affected by food. Although the maximum concentration in the plasma is achieved in 2-3 hours, 60%-70% of this is achieved in 1 hour. A steady state is achieved in 4-5 days. Plasma protein binding is low at 15%. The most unique feature is the relative terminal long half-life of about 26 hours. Frovatriptan is chiefly metabolized by CYP1A2 and is cleared by the kidney and liver making moderate failure of either organ not a limiting factor in treatment^[1].
Frovatriptan (0.1, 0.2, and 0.3 mg/kg; a single bolus intraduodenal administration) treatment produces an increase in carotid vascular resistance, which is sustained for at least 5 hours in dogs^[2].
