Mechanism of Action
Carmapine Oral Suspension 100 mg/5 ml acts on ligand-gated ion channels in the brain, modulating the influx of sodium and calcium and modulating the release of certain neurotransmitters. The mechanism of action is not fully understood, but it is thought that carbamazepine binds to certain binding sites on the sodium and calcium channels, causing a decrease in the frequency of their opening. This leads to a decrease in the influx of sodium and calcium, which leads to a decrease in the release of certain neurotransmitters.
How Long Does it Take to Work?
The effects of carbamazepine can be felt within 1 to 2 weeks of starting treatment. The general rule of thumb is that it takes at least two weeks for the drug to reach its full potential, so patients should not expect to see complete improvement within the first two weeks.

Epilepsy:- Adults and children over 12 years of age- Initial: Either 200 mg b.i.d. for tablets and controlled release tablets, or 1 teaspoon q.i.d. for suspension (400 mg/day). Increase at weekly intervals by adding up to 200 mg/day using a b.i.d or a t.i.d. or q.i.d. regimen of the either formulations until the optimal response is obtained.
- Children 12-15 years of age- Dosage generally should not exceed 1000 mg daily, and 1200 mg daily in patients above 15 years of age. Doses up to 1600 mg daily have been used in adults in rare instances. Maintenance: usually 800-1200 mg daily.
- Children 6-12 years of age- Initial: Either 100 mg b.i.d. for tablets or controlled release tablets, or 1/2 teaspoon q.i.d. for suspension (200 mg/day). Increase at weekly intervals by adding up to 100 mg/day using a b.i.d. or a t.i.d.or q.i.d. regimen of the either formulations until the optimal response is obtained.

- Children under 6 years of age- Initial: 10-20 mg/kg/day b.i.d.or t.i.d. as tablets, or q.i.d. as suspension. Increase weekly to achieve optimal clinical response administered t.i.d. or q.i.d. Maintenance: Ordinarily, optimal clinical response is achieved at daily doses below 35 mg/kg. If satisfactory clinical response has not been achieved, plasma levels should be measured to determine whether or not they are in the therapeutic range. No recommendation regarding the safety of Carbamazepine for use at doses above 35 mg/kg/24 hours can be made.
Trigeminal Neuralgia: Initial: On the first day,either 100 mg b.i.d. for tablets or controlled release tablets, or 1/2 teaspoon q.i.d. for suspension, for a total daily dose of 200 mg. This daily dose may be increased by up to 200 mg/day using increments of 100 mg every 12 hours for tablets or controlled release tablets, or 50 mg (1/2 teaspoon) q.i.d. for suspension, only as needed to achieve freedom from pain. A total dose of 1200 mg daily shouldn't be exceeded. Maintenance: Control of pain can be maintained in most patients with 400-800 mg daily. However, some patients may be maintained on as little as 200 mg daily, while others may require as much as 1200 mg daily. At least once every 3 months throughout the treatment period, attempts should be made to reduce the dose to the minimum effective level or even to discontinue the drug. The tablets or syrup can be taken without regards to meal.
