What is Rizatriptan?
|
|
Rizatriptan
is used to relieve migraine headache symptoms.
However, it will not prevent migraine headaches or
reduce the number of headaches that you have.

How does Rizatriptan work?
|
|
Rizatriptan
belongs to a group of medicines known as serotonin
(or 5HT) agonists. It is used in the treatment of
migraines. Although the cause of migraine attacks is
not fully understood, it is thought that the
widening of blood vessels in the brain causes the
pain associated with migraine attacks. It is also
believed that a chemical called serotonin (5HT) is
released in the brain at the beginning of an attack.
Serotonin causes the release of other chemicals,
which cause blood vessels in the brain to widen.
Serotonin itself causes blood vessels in the brain
to narrow. Rizatriptan binds to serotonin receptors
in the brain, which causes the blood vessels to
narrow. By decreasing the width of blood vessels in
the brain rizatriptan relieves the pain of migraine
headaches.

Rizatriptan
mode of action
|
|
Rizatriptan
comes as a tablet and an orally disintegrating
tablet to take by mouth. It should be taken at the
first sign of a migraine headache. If you are at
risk for heart disease and you have never taken
rizatriptan before, you may need to take the first
dose in your doctor's office. Usually only one dose
is needed. If pain is not relieved with the first
dose, your doctor may prescribe a second dose to be
taken 2 hours after the first dose. Do not take more
than 30 mg of rizatriptan in any 24-hour period. If
you are also taking propranolol (Inderal), you
should not take more than 15 mg of rizatriptan in
any 24-hour period.
