🔹 Pharmacology
Sodium Valproate, the active ingredient of this preparation is endowed with anti-epileptic activity against a variety of seizures. The mechanism by which Sodium Valproate exerts its anti-epileptic effects has not been established. However, it has been suggested that its activity is related to increase brain levels of gamma-aminobutyric acid (GABA).
🔹 Dosage & Administration
Oral: Sodium Valproate tablets may be given once or twice daily and syrup should be given in divided doses.
Epilepsy:
Bipolar disorder: Initially 600 mg daily (20-30 mg/kg/day) in 2-3 divided doses. The maintenance dosage is 1000-2000 mg daily.
Prophylaxis of migraine: 400-600 mg daily, although some may require 1000-1500 mg daily.
Injection:
Epilepsy:
- Adult: Initially, 600 mg daily is given in 2 divided doses, preferably after food, increasing by 200 mg/day at 3-day intervals to a maximum of 2.5 g daily in divided doses until control of seizure is achieved. Usual maintenance dose is 1-2 g daily (20-30 mg/kg daily).

Injection:
- Adults- May be given a slow intravenous injection over 3-5 minutes, usually 400-800 mg depending on body weight (up to 10 mg/kg) followed by continuous or repeated infusion up to a maximum of 2500 mg/day.

🔹 Interaction
Valex CR Vaiproate appears to act as a non specific inhibitor of drug metabolism. Drugs to which it interacts most significantly are Phenobarbital, Phenytoin, Warfarin, Aspirin etc.
🔹 Contraindications
Sodium Valproate is contraindicated to patients who have known hypersensitivity to the drug and liver dysfunction. Use of Sodium Valproate is restricted during pregnancy and in women of childbearing potential.
🔹 Side Effects
The most common side effects are anorexia, nausea and vomiting. However, these side effects are minimized with the use of enteric coated tablets. Effects on the CNS include sedation, ataxia and tremor. These symptoms occur infrequently and usually respond to a decrease in doses. Rash, alopecia and stimulation of appetite have been observed occasionally. Valex CR Vaiproate has several effects on hepatic function of which elevation of liver enzymes in plasma is observed in up to 40% of patients and often occurs asymptomatically during the first few months of therapy. Rarely a fulminate hepatitis that may be fatal may develop. Children below 2 years of age with other medical conditions and those being treated with multiple antiepileptic agents are specially prone to suffer from hepatic injury, acute pancreatitis and hyperammonemia have also been frequently associated with the use of Valex CR.
🔹 Pregnancy & Lactation
Sodium Vaiproate crosses the placenta and in humans, exposure to valproate in the first trimester has been associated with neural tube defects such as anencephaly and spina bifida in newborn. Pregnant women treated with Sodium Vaiproate should be offered to estimate serum a-fetoprotein. Sodium Valproate is excreted in breast miik. However, breast-feeding by a mother taking Sodium Valproate probably causes no risk to the child.
🔹 Precautions & Warnings
Liver functions should be monitored before therapy and during first 6 months especially in patients most at risk, No undue potential for bleeding before starting and before major surgery must be ensured, Care should be taken in renal impairment, pregnancy, breast-feeding and systemic lupus erythematosus. Valex CR is partially eliminated in the urine as a ketone metabolite, which may lead to a false interpretation of the urine ketone test. Sudden withdrawal of therapy should be avoided. Valex CR should not be used during pregnancy and in women of childbearing potential.
🔹 Storage Conditions
Do not store above 30°C. Keep away from light and out of the reach of children.
