What is Maxalt-MLT used for?
Maxalt-MLT is a prescription medicine that is used to treat migraine headaches.
MAXALT contains rizatriptan benzoate, a selective 5-hydroxytryptamine1B/1D (5-HT1B/1D) receptor agonist.
Rizatriptan benzoate is described chemically as: N,N-dimethyl-5-(1H-1,2,4-triazol-1-ylmethyl)-1H-indole-3-ethanamine monobenzoate and its structural formula is:
Its empirical formula is C15H19N5•C7H6O2, representing a molecular weight of the free base of 269.4. Rizatriptan benzoate is a white to off-white, crystalline solid that is soluble in water at about 42 mg per mL (expressed as free base) at 25°C.
MAXALT Tablets and MAXALT-MLT Orally Disintegrating Tablets are available for oral administration in a strength of 10 mg (corresponding to 14.53 mg of the benzoate salt). Each compressed tablet contains the following inactive ingredients: lactose monohydrate, microcrystalline cellulose, pregelatinized starch, ferric oxide (red), and magnesium stearate.
Each lyophilized orally disintegrating tablet contains the following inactive ingredients: gelatin, mannitol, glycine, aspartame, and peppermint flavor.
Mechanism of Action
Rizatriptan binds with high affinity to human cloned 5-HT1B/1D receptors. MAXALT presumably exerts its therapeutic effects in the treatment of migraine headache by binding to 5-HT1B/1D receptors located on intracranial blood vessels and sensory nerves of the trigeminal system.
