Product Name:

Tegrital 400mg
Generic Name: Carbamazepine
Strength: 400mg
Form: Oral Tablet
Therapeutic Class: Anticonvulsant / Mood Stabilizer

Product Description:

Tegrital 400mg contains Carbamazepine, which is an anticonvulsant medication and mood stabilizer mostly utilized to treat epilepsy and specific mood disorders. Carbamazepine has been a fundamental treatment for neurological and psychiatric conditions since the 1960s.

The medication reduces the high electrical activity of the brain, which triggers seizures, as well as stabilizes the mood swings that occur in bipolar disorder. Tegrital can also be used in treating certain kinds of nerve pains, such as trigeminal neuralgia.

Uses and Indications:

Tegrital 400mg is prescribed for:

1. Epilepsy:
   • Focal (partial) seizures, with or without secondary generalization.
   • Generalized tonic-clonic seizures.
   • Mixed seizure types.
2. Bipolar Disorder:
   • Stabilization of moods, especially in the manic or mixed episode.
3. Neuropathic Pain:
   • Trigeminal neuralgia (severe facial nerve pain).
   • Off-label use is often used for conditions of the nerve.
4. Other Indications:
   • Sometimes, it is used for specific psychiatric disorders as an additional treatment.

Mechanism of Action:

Carbamazepine is a drug that blocks the sodium-gated voltage channels that are present in neurons’ membranes. It stabilizes nerve cells that are hyperexcited and reduces the frequency of firing and slows down the progression of seizures in the brain. Also, it regulates neurotransmitter release, which contributes to mood stability.

Dosage and Administration:

• Starting Dose: The usual dosage is 200 mg twice a day; the dosage can be gradually increased.
• Maintenance Dose: The typical dose is between 400mg and 1200mg in divided doses, based on the patient’s condition and responses.
• Maximum Dose: Up to 1600mg/day in some cases.
• Route: Oral administration in conjunction with food intake helps reduce stomach upset.
• Extended-Release Formulations: Most often, it is recommended to have stable blood levels.

Important: The dosage should be individualized and monitored by a healthcare professional, and blood levels should be monitored as required.
