Abstract

Insights

Perindopril arginine may enhance levetiracetam (LEV) anticonvulsant effects, while other cardiovascular drugs show neutral interactions. This study investigated drug interactions between antiepileptics and cardiovascular medications in mice.

Area of Science:

  • Pharmacology
  • Neuroscience
  • Clinical Pharmacy

Background:

  • Epilepsy frequently co-occurs with hypertension and heart failure, increasing the risk of drug interactions between antiepileptics and cardiovascular medications.
  • Understanding these interactions is crucial for safe and effective patient management.

Purpose of the Study:

  • To evaluate the impact of specific cardiovascular drugs on the anticonvulsant activity of levetiracetam (LEV) in a mouse model.
  • To assess potential adverse effects of combined drug treatments.

Main Methods:

  • The anticonvulsant effects of LEV were assessed using the maximal electroshock seizure threshold test in mice.
  • Cardiovascular drugs (angiotensin AT1 receptor antagonists, ACE inhibitors, diuretics) were administered intraperitoneally, alone and in combination with LEV.
  • Safety was evaluated through passive avoidance and chimney tests.

Main Results:

  • Perindopril arginine significantly enhanced the anticonvulsant activity of LEV at tested doses.
  • Losartan potassium, candesartan cilexetil, captopril, hydrochlorothiazide, and ethacrynic acid did not alter LEV's anticonvulsant efficacy.
  • No adverse effects were observed in combined treatments, suggesting a pharmacodynamic interaction with perindopril arginine.

Conclusions:

  • Perindopril arginine may offer a beneficial interaction, potentially enhancing anticonvulsant effects of LEV in epileptic patients.
  • Other tested cardiovascular agents (losartan, candesartan, captopril, hydrochlorothiazide, ethacrynic acid) appear to have neutral effects on LEV's anticonvulsant activity.
  • Further clinical studies are warranted to confirm these findings in human patients.

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Electroconvulsive Therapy01:30

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

Antiepileptic Drugs: GABAergic Pathway Potentiators

γ-aminobutyric acid or GABA, plays a pivotal role as an inhibitory neurotransmitter in the brain. GABA pathway potentiators, also known as GABAergic drugs, are a class of pharmaceutical agents designed to enhance the functioning of the GABAergic system. These medications primarily treat epilepsy, a neurological disorder characterized by recurrent seizures.
The key GABA pathway potentiators used in epilepsy management are as follows.
Benzodiazepines are a well-known class of drugs used for...

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Antiepileptic Drugs: Potassium Channel Activators

Ezocgabine or retigabine, an antiepileptic drug of remarkable efficacy, has revolutionized the management of seizures. It is a potassium channel activator, explicitly targeting the family of Q subtype potassium channels. It enhances the transmembrane potassium currents, regulating neuronal excitability. This action stabilizes the resting membrane potential, a pivotal factor in mitigating the hyperexcitability that characterizes epilepsy.
Ezogabine has gained approval as an adjunctive treatment...

Antiepileptic Drugs: Glutamate Antagonists

Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...
