Topamax is the brand name for the generic drug Topiramate. The drug has been marketed as an anticonvulsant. The chemical structure is a little unusual for anticonvulsants. Topiramate is related to fructose – it is a monosaccharide with a sulfamate group substitution. The drug is used orally and is absorbed very fast. 0% of it is eliminated from the body through urine in an unchanged condition. The mechanism of action of this medicine has not been discovered. It has been suggested that four properties of the drug may contribute to its effectiveness in antimigraine and antiepileptic medication. These include its ability to block voltage gated sodium ion channels in the cell membranes, action at different signal transduction receptors and inhibition of the enzyme carbonic anhydrase.
Conditions Treated by Topamax
Topamax is used in children affected with Lennox-Gastaut syndrome, a disorders that causes delay in development and symptoms include seizures.

Investigations have been conducted for assessing the efficacy of the drug in the treatment of alcoholism and obesity, especially for reducing binge eating. Clinical trials have been made with this drug to test if it can be used to treat posttraumatic stress disorder.
Topamax Dosage Information
a.) Typical Dosage Recommendations
The diagnosis determines the dosage. Initially the dosage is kept to low, typically 25 to 50 mg per day in 2 unit doses, to prevent early side-effects like cognitive dysfunction. The dosage is increased slowly in gradual steps. Maintenance treatment dosage is commonly kept at 100 to 200 mg daily. Recommended highest dosage is 400 mg per day in divided doses. But patients using Topamax as the primary drug for the treatment of seizures have well tolerated higher dosages up to 1600 mg daily.
b.) Missing a Dose
Just in case you forget a dose take it as soon as you remember. If the time is close to that for your next dose, say within 6 hours of the next dose, skip the missed dose and start with the next dose at the regular scheduled time. Do not take double doses to make up for the missed dose. Ask your doctor for advice in case you forget to take more than a single dose.
If you accidentally take an overdose contact your local emergency room or poison control centre as soon as possible.
If you experience sudden alteration in vision or pain around or behind your eyes, seek medical help immediately because these can be early signs of a serious side effect of Topamax. Do not alter the dosage or stop taking the drug without first consulting your doctor, even if you feel your condition has improved. This may result in increased occurrence of seizures. The dosage should be gradually deceased before stopping it entirely. Contact your doctor as soon as you can if you feel worsening of symptoms or any new symptom comes up, like changes in behavior, mood swings, depression, anxiety, feelings of agitation, restlessness, suicidal tendencies and the like. Do not get involved in activities requiring mental alertness and coordination until possible side effects are ruled out. Remember that efficacy of oral contraceptives containing estrogen may be reduced by Topamax. Consider carrying an ID card or wearing medical alert bracelets stating that you are under topiramate medication, which may come in useful in medical emergencies. Doctors treating you should know that you take medications for seizure. Avoid high protein diets as these can increase the risk of kidney stone formation.
