Convules CR 300 is used to treat all types of epilepsy, including partial seizures, absence seizures (petit mal), generalized tonic-clonic seizures (grand mal), myoclonic seizures, atonic seizures, and mixed seizures with absence attacks.

Pharmacology
Convules CR 300 contains Sodium Valproate, which has anti-epileptic effects against different types of seizures. The exact way Convules CR 300 works is not fully understood, but Convules CR 300 is believed to increase the brain levels of gamma-aminobutyric acid (GABA), which helps in controlling seizures.

Acute pancreatitis and high ammonia levels are also linked with its use.
