Ritza: Introduction

Ritza (Maxalt, Maxalt-MLT) is a serotonin 5-HT1B/1D receptor agonist and antimigraine drug. It is used to treat acute migraine attacks, with or without aura (temporary visual disturbances or other symptoms), in adults. Ritza relieves migraine pain and associated symptoms such as nausea and sensitivity to sound and light.

Uses For

Ritza is used to treat the symptoms of migraine headaches (severe, throbbing headaches that sometimes are accompanied by nausea and sensitivity to sound and light). Ritza will not prevent the occurrence of migraine headaches.

Mechanism of Action

Ritza is a serotonin 5-HT1B/1D receptor agonist with antimigraine activity. It binds selectively and with high affinity to 5-HT1B and 5-HT1D receptors, resulting in serotonin-mediated constriction of arteriolar blood vessels in the brain, relief from pain, and a decrease in inflammation. It is also thought to inhibit release of neuropeptides such as CGRP (calcitonin gene-related peptide), which is associated with migraine.

How Long Does it Take to Work?

Ritza usually begins to work within 30 minutes of taking the tablet, and reaches its peak effect within two hours.

Absorption

Ritza is rapidly and well-absorbed from the gastrointestinal tract. The absolute bioavailability is 25%, because of presystemic metabolism. Peak plasma concentrations occur 1-2 hours after oral administration. The bioavailability of Maxalt-MLT (a lyophilized orally disintegrating tablet) is comparable to that of Maxalt.

Route of Elimination

Ritza is eliminted primarily by hepatic metabolism and biliary excretion of metabolites. The drug has a plasma terminal elimination half-life of about 2 to 3 hours.

Dosage

The usual recommended adult dose of rizatriptan is 5 to 10 mg. Dose can be increased to a maximum of 30 mg in a 24-hour period.

Administration

Ritza tablets should be taken whole. They should not be chewed, split, or dissolved. Maxalt-MLT orally disintegrating tablets should be placed on the tongue and allowed to dissolve without being chewed or swallowed.
