Pharmacology
Valproate is a generic term used to describe valproic acid, its salts and derivatives. It is available in various forms including the sodium salts (valproate semisodium and sodium valproate), the amide derivative (valpromide), or as valproic acid. Valproate is a carboxylic acid anticonvulsant. It has been suggested that its antiepileptic activity is related to increased brain levels of γ-aminobutyric acid (GABA).
Dosage & Administration
Soduim Valproate & Valproic Acid is a prolong release formulation of sodium Valproate, thus Soduim Valproate & Valproic Acid may be given once or twice daily.

Children Initially 20 mg/kg daily in divided doses, may be increased (up to 20 kg) provided plasma concentrations monitored (above 40 mg/kg daily also monitor clinical chemistry and hematological parameters).
Children Initially 400 mg daily in divided doses increased until control (0ver 20 kg) (usually in the range of 20-30 mg/kg daily); Maximum 35 mg/kg daily. Febrile convulsion 20-30 mg/kg/day in 3 divided doses.

Interaction
Valex CR 200- Sodium Valproate 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
Valex CR 200- Sodium Valproate is contraindicated to patients who have known hypersensitivity to the drug and liver dysfunction. Care should be exercised when prescribing Sodium Valproate in women of child bearing age.

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. Sodium Valproate 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 Sodium Valproate.

Pregnancy & Lactation
Valex CR 200- Sodium Valproate 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 Soduim Valproate & Valproic Acid should be offered to estimate serum a-fetoprotein. This is excreted in breast milk. However, breast-feeding by a mother taking Soduim Valproate & Valproic Acid probably causes no risk to the child.

Precautions
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. Sodium Valproate 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.

Storage Conditions
Store in a cool and dry place, below 30° C and keep away from light.
