Sumtan
Sumtan Uses, Dosage, Side Effects, Food Interaction and all others data.
Sumtan binds with high affinity to human cloned 5-HT1B/1D receptors. Sumtan presumably exerts its therapeutic effects in the treatment of migraine and cluster headaches through agonist effects at the 5-HT1B/1D receptors on intracranial blood vessels and sensory nerves of the trigeminal system, which result in cranial vessel constriction and inhibition of pro-inflammatory neuropeptide release.
Sumtan constricts cranial blood vessels and prevents the release of vasoactive peptides. The dose of sumatriptan varies widely by route of administration and in most cases, no more than 2 doses should be given daily. Medication overuse headaches may occur in patients who use sumatriptan frequently.

Uses
Sumtan Succinate is used for adults for the acute treatment of migraine (with or without aura), and the acute treatment of cluster headache.
Sumtan is also used to associated treatment for these conditions: Acute Migraine, Acute Cluster headaches
How Sumtan works
Sumtan is an agonist of 5-HT1B and 5-HT1D. This agonism leads to constriction of cranial blood vessels and inhibits the release of pro-inflammatory neuropeptides. Sumtan decreases carotid arterial blood flow, but increases blood flow velocity in the internal carotid artery and middle cerebral artery.
Dosage
Sumtan dosage
Migraine: 50-100 mg repeated at 2-hr intervals if migraine recurs. Max: 300 mg/24 hr.
Take thismedicationbymouthwith or without food as directed by your doctor, at the first sign of amigraine. The dosage is based on your medical condition and response to treatment. If there is no improvement in your symptoms, do not take more doses of this medication before talking to your doctor. If your symptoms are only partly relieved, or if yourheadachecomes back, you may take another dose at least two hours after the first dose. Do not take more than 200 milligrams in a 24-hour period.
If you are using drugs formigraineattacks on 10 or more days each month, the drugs may actually make yourheadachesworse (medication overuseheadache). Do not usemedicationsmore often or for longer than directed. Tell your doctor if you need to use this medication more often, or if the medication is not working as well, or if yourheadachesget worse.
Side Effects
Transient hypertension, hypotension, dizziness, flushing, fatigue, drowsiness, weakness, seizures, nausea and vomiting, heat, tightness in any part of body, paraesthesia, seizures, inj site reactions, irritation of nasal mucosa and epistaxis. Rebound headache with frequent use.
Toxicity
Symptoms of overdose include convulsions, tremor, paralysis, inactivity, ptosis, erythema of the extremities, abnormal respiration, cyanosis, ataxia, mydriasis, salivation, and lacrimation. Overdoses may be fatal and patients should be monitored for 3-5 half lives or while symptoms persist.
Precaution
Conditions predisposing to seizures, presence of coronary risk factors, cardiac arrhythmias, renal or hepatic impairment, elderly, pregnancy, lactation.
Interaction
Concurrent use increased risk of vasospastic reaction with ergotamine and related compounds.
Food Interaction
- Avoid excessive or chronic alcohol consumption. Alcohol increased the risk of GI bleeding, ulcer, and perforation when taken with sumatriptan.
- Take with or without food.
Sumtan Cholesterol interaction
[Major] The group of drugs known as 5-hydroxytryptamine1 receptor (5-HT1) agonists can cause vasospastic reactions, including coronary vasospasm, peripheral vascular ischemia, and colonic ischemia.
Rarely, serious adverse cardiac events including acute myocardial infarction, arrhythmia, cardiac arrest, and death have been reported within a few hours following the administration of 5-HT1 agonists, in some cases even in patients with no prior history or findings of coronary artery disease (CAD).
Significant elevation in blood pressure, including hypertensive crisis, has also been reported on rare occasions in patients with and without a history of hypertension, as have transient increases in blood pressure and peripheral vascular resistance.
In general, patients with potentially unrecognized CAD as predicted by the presence of risk factors (e.g., hypertension, hypercholesterolemia, tobacco use, obesity, diabetes, strong family history of CAD, female with surgical or physiological menopause, or male over 40 years of age) should not be administered 5-HT1 agonists unless a cardiovascular evaluation provides satisfactory clinical evidence indicating the lack of CAD, ischemic heart disease, or other significant underlying cardiovascular disease.
As a precaution, the manufacturers recommend that the first dose be administered under medical surveillance in such patients, and that electrocardiographic monitoring be considered during the interval immediately following administration to help detect any asymptomatic cardiac ischemia that may occur.
Periodic cardiovascular evaluations should be performed during intermittent, long-term use.
