Neurocet 500 mg/5 ml Oral Solution
Neurocet 500 mg/5 ml Oral Solution Uses, Dosage, Side Effects, Food Interaction and all others data.
The exact mechanism of anticonvulsant effect is unknown but does not involve inhibitory and excitatory neurotransmission. Stereo-selective binding of Neurocet 500 mg/5 ml Oral Solution was confined to synaptic plasma membranes in the central nervous system with no binding occurring in peripheral tissue.
Studies show that levetiracetam affects intraneuronal Ca levels by partial inhibition of N-type Ca currents and by reducing the release of Ca from intraneuronal stores; facilitates GABA-ergic inhibitory transmission through displacement of negative modulators; reduces delayed rectifier K current; and/or binds to synaptic proteins which modulate neurotransmitter release.
Neurocet 500 mg/5 ml Oral Solution 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.

How Neurocet 500 mg/5 ml Oral Solution works
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. Neurocet 500 mg/5 ml Oral Solution 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.
Neurocet 500 mg/5 ml Oral Solution 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.

Side Effects
Dizziness, drowsiness, irritability, sore throat, tiredness, weakness are some common adverse effects. In rare cases severe allergic reaction may happen.
Toxicity
The oral TDLO of levetiracetam in humans is 10 mg/kg. Symptoms of levetiracetam overdose are consistent with its adverse effect profile and may include agitation, aggression, somnolence, decreased level of consciousness, respiratory depression, or coma. There is no antidote for levetiracetam overdose, therefore management should involve general supportive measures and symptomatic treatment. Hemodialysis results in significant clearance of plasma levetiracetam (approximately 50% within 4 hours) and should be considered in cases of overdose as indicated by the patient's status.
Precaution
Severe allergic reactions, abnormal thoughts; dark urine; decreased coordination; extreme dizziness, drowsiness, tiredness, or weakness; fever, chills, or persistent sore throat; hallucinations; memory loss; mouth sores; muscle or neck pain; new or worsening mental problem; mood or behavior changes; new or worsening seizures; pain, itching or redness at the injection site;suicidal thoughts or attempts; unusual bruising or bleeding; vision changes; yellowing of the skin or eyes.
Interaction
No potential drug interaction has been reported
Food Interaction
- Take with or without food. Co-administration with food slightly alters pharmacokinetics, but not to a clinically significant extent.
[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents.
Use in combination may result in additive central nervous system depression and
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol.
Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Volume of Distribution
The volume of distribution of levetiracetam is approximately 0.5 to 0.7 L/kg.
Elimination Route
Neurocet 500 mg/5 ml Oral Solution is rapidly and nearly completely absorbed following oral administration, with a reported absolute oral bioavailability of essentially 100%. Tmax is approximately 1.3 hours after dosing, and Cmax is 31 μg/mL following a single 1000mg dose and 43 μg/mL following repeated dosing. Co-administration of levetiracetam with food delays Tmax by approximately 1.5 hours and decreases Cmax by 20%.
Half Life
The plasma half-life of levetiracetam is 6-8 hours and is not affected by dose or repeat administration. Half-life is increased in the elderly (by about 40%) and those with renal impairment.
Clearance
The total plasma clearance of levetiracetam is 0.96 mL/min/kg, with renal clearance comprising 0.6 mL/min/kg. The primary inactive metabolite of levetiracetam, L057, has a renal clearance of 4 mL/min/kg. Given the relatively high proportion of drug undergoing renal clearance, overall clearance of levetiracetam is reduced in patients with renal impairment.
Elimination Route
Approximately 66% of the administered dose of levetiracetam is excreted in the urine as unchanged drug, while only 0.3% of the total dose is excreted via the feces. The primary inactive metabolite of levetiracetam, L057, is also found in the urine as approximately 24% of the administered dose.
