black triangle Frovatriptan, a new serotonin receptor agonist developed for the acute treatment of migraine, has high affinity for serotonin 5-HT1B and 5-HT1D receptor subtypes and is a potent stimulator of contraction in human basilar arteries. black triangle A long terminal elimination half-life (approximately 26 hours) is a distinctive pharmacokinetic feature of frovatriptan which appears to be independent of dose, age, gender and renal function. black triangle A single oral dose of frovatriptan 2.5mg was effective in the acute treatment of migraine providing meaningful relief within 2 hours to approximately twice as many recipients as placebo in clinical trials. black triangle Consistent relief of migraine symptoms was achieved in patients who treated a number of consecutive attacks with frovatriptan and the incidence of 24-hour migraine recurrence was reduced. black triangle Frovatriptan was well tolerated in clinical trials, with the overall incidence of adverse events occurring with frovatriptan 2.5mg only slightly higher than that reported with placebo. Mild to moderate fatigue, nausea and paraesthesia were the most commonly reported drug-related adverse events.

Frovatriptan is a 5-HT(1B/1D) agonist demonstrating consistently effective headache relief at a low dose of 2.5 mg. A striking pharmacokinetic characteristic is its long half-life of 25 h. This is balanced by an average Tmax of 2-3 h, a low degree of lipophilicity and a low oral bioavailability of 24-30%. Fifty per cent of the drug is renally excreted and the rest is partially metabolized by P450 CYP 1A2. In three short-term multicentre, double-blind, placebo-controlled phase III trials, the 2 h headache response for 2.5 mg frovatriptan varied from 36 to 46% (placebo 21-27%). The 4 h headache responses were considerably higher--up to 65%. Thirty-five per cent of patients were consistent rapid responders. The recurrence rate was 10-25%. In addition to effective and prolonged relief of head pain, frovatriptan reduced associated migraine symptoms such as nausea, photophobia and phonophobia. There was an excellent tolerability profile with the incidence of adverse events for frovatriptan only slightly higher than placebo. The most commonly reported adverse events for both frovatriptan and placebo were dizziness, nausea, headache and fatigue.

Frovatriptan belongs to an innovative family of compounds aimed at breaking through the long-standing barrier of migraine headache understanding and treatment. While a typology of headaches has been recognized for some time, and a number of therapies have been introduced for reduction of headache pain and duration, the causes of migraine remain a subject of debate. Those prone to attacks continue to endure them and suffer the related symptoms such as nausea and disorientation. Frovatriptan, like all the triptans, acts by inducing vasoconstriction of the meningeal arteries. It has been shown in pharmacological tests to act selectively as a potent agonist of serotonin 5-HT1B/1D receptors. Frovatriptan has been well tolerated in humans and efficacious in reducing headache pain and duration in clinical trials, which have also indicated that dose adjustments for age or gender are not necessary for the drug. Patients have found the use of frovatriptan acceptable over the long-term, and overall a low-incidence of adverse effects has been reported. Though not a prophylactic, frovatriptan has demonstrated the potential to significantly improve the therapeutic approaches to the treatment of migraine.
