Clinical monograph: Levetiracetam

BNF-referenced

Levetiracetam is an antiepileptic drug primarily used in the management of epilepsy and other seizure disorders. It is recognized for its unique mechanism of action, which distinguishes it from other antiepileptic medications. Levetiracetam is typically well tolerated and has a wide therapeutic index, making it a preferred choice in various clinical settings. Its ability to modulate synaptic transmission without affecting normal neuronal activity contributes to its efficacy in seizure control.

Indications

  • Epilepsy
  • Focal seizures
  • Generalized tonic-clonic seizures
  • Myoclonic seizures in juvenile myoclonic epilepsy

Mechanism of action

Levetiracetam exerts its antiepileptic effects by binding to synaptic vesicle protein 2A (SV2A), a protein found on synaptic vesicles within the central nervous system. This binding is thought to play a crucial role in vesicle exocytosis and the modulation of synaptic transmission. By stimulating pre-synaptic SV2A, levetiracetam may inhibit the release of neurotransmitters during pathological conditions without interfering with normal neurotransmission. Additionally, it has been shown to indirectly affect GABAergic transmission and may inhibit N-type calcium channels, although the implications of these actions for its antiepileptic effects remain to be fully understood.

Pharmacodynamics

Levetiracetam prevents seizure activity primarily by selectively inhibiting hypersynchronized epileptiform burst firing, while preserving normal neuronal transmission. It has a wide therapeutic index, which implies a lower risk of toxicity compared to other antiepileptic drugs. However, it is important to monitor patients for potential emergence or worsening of depressive symptoms, suicidal ideation, and behavioral changes, as there is an associated increased risk of such effects with the use of antiepileptic medications, including levetiracetam.

Pharmacokinetics

Levetiracetam is rapidly absorbed after oral administration, with peak plasma concentrations typically achieved within 1 to 1.5 hours. It is primarily eliminated by the kidneys, with approximately 66% of an administered dose excreted unchanged in the urine. The half-life of levetiracetam is approximately 7 to 8 hours in adults, and it does not undergo significant metabolism, which limits drug-drug interactions. Dose adjustments may be necessary in patients with renal impairment.

Adverse effects

  • Drowsiness
  • Fatigue
  • Irritability
  • Dizziness
  • Nausea
  • Vomiting
  • Aseptic meningitis
  • Suicidal behaviour

Clinical monograph: acetic

Acetic acid, commonly known as vinegar when diluted, is a colorless organic compound with a pungent smell and sour taste. It is primarily used in various applications including food preservation, flavoring, and as a chemical reagent. In medicine, it has antiseptic properties and is utilized in various formulations for its therapeutic effects, particularly in treating infections and as an astringent.

Indications

  • Infections (topical treatment)
  • Wound care (as an antiseptic)
  • Ear infections (as an ear drop solution)
  • Acid-base balance in metabolic acidosis

Dosage

Children: Refer to established guidelines as dosage may vary based on the formulation and indication.

Adults: Refer to established guidelines as dosage may vary based on the formulation and indication.

Mechanism of action

Acetic acid exerts its effects primarily through its ability to lower pH levels, creating an acidic environment which is inhospitable to many pathogens. It can disrupt the integrity of microbial cell membranes, leading to cell lysis and death. Additionally, acetic acid can promote the healing of wounds and enhance the absorption of certain medications when used as a solvent.

Pharmacodynamics

The pharmacodynamics of acetic acid involve its interaction with biological systems, leading to changes in cellular functions. Its acidic nature helps in the denaturation of proteins and disruption of microbial metabolism. This contributes to its antibacterial and antifungal activities, making it effective against a range of pathogens.

Pharmacokinetics

Acetic acid is rapidly absorbed in the gastrointestinal tract when ingested. It is metabolized primarily in the liver, converting to acetyl CoA and subsequently entering various metabolic pathways including the citric acid cycle. The elimination half-life varies but is generally short, with excretion occurring mainly via urine. When applied topically, absorption is minimal, and local effects are predominant.

Pregnancy

The safety of acetic acid during pregnancy has not been established. Use only if the potential benefit justifies the potential risk to the fetus.

Breast-feeding

There is no specific information available regarding the use of acetic acid during breastfeeding. Caution is advised.

Storage

Store in a cool, dry place away from direct sunlight. Keep tightly closed in a well-ventilated area.

Molecular reference: Levetiracetam

PubChem CID 5284583

Molecular formula: C8H14N2O2

Mechanism of action

The exact mechanism through which levetiracetam exerts its anti-epileptic effects is unclear, but is thought to be unique amongst other anti-epileptic medications. Current knowledge suggests that levetiracetam’s binding to synaptic vesicle protein 2A (SV2A) is a key driver of its action. SV2A is a membrane-bound protein that is found on synaptic vesicles and is ubiquitous throughout the CNS - it appears to play a role in vesicle exocytosis and in the modulation of synaptic transmission by increasing the available amount of secretory vesicles available for neurotransmission. Stimulation of pre-synaptic SV2A by levetiracetam may inhibit neurotransmitter release, but this action does not appear to affect normal neurotransmission. This has led to the suggestion that levetiracetam exclusively modulates the function of SV2A only under pathophysiological conditions. Levetiracetam and related analogues showed a correlation between affinity for SV2A and anti-epileptic potency, further suggesting that action at this site contributes to the anti-epileptic activity of the drug. Levetiracetam has also been shown to indirectly affect GABAergic neurotransmission (despite having no direct effect on GABAergic or glutamatergic receptors) and modulate ionic currents. Similarly, levetiracetam has been shown in vitro to inhibit N-type calcium channels. How, or even if, these actions are implicated in its anti-epileptic action have yet to be elucidated. The precise mechanism by which levetiracetam exerts its antiepileptic effect is unknown. The antiepileptic activity of levetiracetam was assessed in a number of animal models of epileptic seizures. Levetiracetam did not inhibit single seizures induced by maximal stimulation with electrical current or different chemoconvulsants and showed only minimal activity in submaximal stimulation and in threshold tests. Protection was observed, however, against secondarily generalized activity from focal seizures induced by pilocarpine and kainic acid, two chemoconvulsants that induce seizures that mimic some features of human complex partial seizures with secondary generalization. Levetiracetam also displayed inhibitory properties in the kindling model in rats, another model of human complex partial seizures, both during kindling development and in the fully kindled state. The predictive value of these animal models for specific types of human epilepsy is uncertain. In vitro and in vivo recordings of epileptiform activity from the hippocampus have shown that levetiracetam inhibits burst firing without affecting normal neuronal excitability, suggesting that levetiracetam may selectively prevent hypersynchronization of epileptiform burst firing and propagation of seizure activity. Levetiracetam at concentrations of up to 10 muM did not demonstrate binding affinity for a variety of known receptors, such as those associated with benzodiazepines, GABA (gammaaminobutyric acid), glycine, NMDA (N-methyl-D-aspartate), re-uptake sites, and second messenger systems. Furthermore, in vitro studies have failed to find an effect of levetiracetam on neuronal voltage-gated sodium or T-type calcium currents and levetiracetam does not appear to directly facilitate GABAergic neurotransmission. However, in vitro studies have demonstrated that levetiractem opposes the activity of negative modulators of GABA- and glycine-gated currents and partially inhibits N-type calcium currents in neuronal cells. A saturable and stereoselective neuronal binding site in rat brain tissue has been described for levetiracetam. Experimental data indicate that this binding site is the synaptic vesicle protein SV2A, thought to be involved in the regulation of vesicle exocytosis. Although the molecular significance of levetiracetam binding to synaptic vesicle protein SV2A is not understood, levetiracetam and related analogs showed a rank order of affinity for SV2A which correlated with the potency of their antiseizure activity in audiogenic seizure-pro

Pharmacodynamics

Levetiracetam appears to prevent seizure activity via the selective inhibition of hypersynchronized epileptiform burst firing without affecting normal neuronal transmission, though the exact mechanism through which this occurs is unclear. The therapeutic index of levetiracetam is wide, making it relatively unique amongst other anti-epileptic medications. Anti-epileptic drugs, including levetiracetam, may increase the risk of suicidal ideation or behaviour - patients taking levetiracetam should be monitored for the emergence or worsening of depressive symptoms, suicidal ideation, and behavioural abnormalities.
