Pharmacological properties

Ipnopan contains Levetiracetam, an antiepileptic, belonging to a new group of drugs derived from pyrrolidone. (α-ethyl-2-oxo-1-pyrrolidone acetamide s-enantiomer), without chemical relationship with existing antiepileptic active ingredients.

Its site of action is the SV2A protein in the brain synaptic vesicle. This protein plays a substantial role in the release of neurotransmitters essential for normal neuronal activity in the brain and spinal cord.

Therapeutic indications

Ipnopan is indicated as monotherapy in the treatment of epileptic seizures, either focal or generalized: juvenile myoclonic epilepsy, in the treatment of primary generalized tonic-clonic seizures in adults and adolescents over 12 years of age with Idiopathic Generalized Epilepsy.


Hypersensitivity reactions to Levetiracetam or other derivatives of pyrrolidone or any of its excipients.

Side Effects


They are infrequent at the recommended doses; Drowsiness and asthenia have been described in some patients. Other very rare side effects are dizziness, emotional lability, insomnia, tremors, ataxia, digestive disturbances, and skin rash. Headache and chest pain have also been described.

Drug interactions

Studies have shown that Levetiracetam does not influence plasma levels of Carbamazepine, Phenytoin, Primidone, Valproate, Digoxin or Warfarin. The total absorption of Levetiracetam is not reduced by food, but it slows down. There are no studies on the interaction of Levetiracetam with alcohol.


In patients with renal failure, the daily dose should be adjusted according to the creatinine index. Moderate liver failure requires no adjustment. According to current clinical practice, if it is necessary to discontinue therapy with Levetiracetam, it is recommended to withdraw it gradually. (in adults: 500 mg reductions 2 times a day every 2 to 4 weeks; in children: the dose decrease should not exceed 10 mg / kg 2 times a day every 2 weeks.

Use in children younger than 4 years: Ipnopan is not recommended for use in children younger than 4 years, due to a paucity of data on safety and efficacy in this age group.

Use during pregnancy and lactation:

There are no adequate data on the use of Levetiracetam in pregnant women. Animal studies have shown reproductive toxicity. The potential risk to humans is unknown. Levetiracetam should not be used during pregnancy unless clearly necessary.

Levetiracetam is excreted in human breast milk. Therefore breastfeeding is not recommended. However, if you need treatment with Levetiracetam while breastfeeding, the risk / benefit of treatment should be evaluated considering the importance of breastfeeding.

Effects on ability to drive vehicles and operate machinery

No studies on the effects on the ability to drive vehicles and operate machinery have been performed. Due to possible differences in individual sensitivities, some patients may experience drowsiness or other symptoms related to the central nervous system, at the start of treatment or after an increase in dose. Therefore, caution is recommended in such patients when performing delicate tasks, driving vehicles or operating machinery.
