Lametec Kid Dt

Lametec Kid Dt Uses, Dosage, Side Effects, Food Interaction and all others data.

Lametec Kid Dt controls epileptic seizures by inhibiting voltage-sensitive sodium channels, thereby stabilizes neuronal membranes and consequently inhibits presynaptic excitatory neurotransmitter (e.g., glutamate and aspartate) release.

Lametec Kid Dt likely prevents seizures and prevents mood symptoms via stabilizing presynaptic neuronal membranes and preventing the release of excitatory neurotransmitters such as glutamate, which contribute to seizure activity.

A note on cardiovascular effects

The metabolite of lamotrigine, 2-N-methyl metabolite (formed by glucuronidation), is reported to cause dose-dependent prolongations of the PR interval, widening of the QRS complex, and at higher doses, complete AV block. Although this harmful metabolite is only found in trace amounts in humans, plasma concentrations may increase in conditions that cause decreased drug glucuronidation, such as liver disease.

Uses

Lametec Kid Dt is an antiepileptic drug (AED) used for:

Epilepsy (adjunctive therapy in patients aged 2 years and older):

  • Partial: Onset seizures.
  • Primary generalized tonic: Clonic seizures.
  • Generalized seizures of Lennox: Gastaut syndrome.

Epilepsy (monotherapy in patients aged 16 years and older).Bipolar disorder in patients aged 18 years and older.

Lametec Kid Dt is also used to associated treatment for these conditions: Bipolar 1 Disorder, Grand mal Generalized tonic-clonic seizure, Partial-Onset Seizures, Generalized seizure, Conversion to monotherapy

How Lametec Kid Dt works

The exact mechanism of action of lamotrigine is not fully elucidated, as it may exert cellular activities that contribute to its efficacy in a range of conditions. Although chemically unrelated, lamotrigine actions resemble those of phenytoin and carbamazepine, inhibiting voltage-sensitive sodium channels, stabilizing neuronal membranes, thereby modulating the release of presynaptic excitatory neurotransmitters.

Lametec Kid Dt likely acts by inhibiting sodium currents by selective binding to the inactive sodium channel, suppressing the release of the excitatory amino acid, glutamate. The mechanism of action of lamotrigine in reducing anticonvulsant activity is likely the same in managing bipolar disorder. Studies on lamotrigine have identified its binding to sodium channels in a fashion similar to local anesthetics, which could explain the demonstrated clinical benefit of lamotrigine in some neuropathic pain states.

Lametec Kid Dt displays binding properties to several different receptors. In laboratory binding assays, it demonstrates weak inhibitory effect on the serotonin 5-HT3 receptor. Lametec Kid Dt also weakly binds to Adenosine A1/A2 receptors, α1/α2/β adrenergic receptors, dopamine D1/D2 receptors, GABA A/B receptors, histamine H1 receptors, κ-opioid receptor (KOR), mACh receptors and serotonin 5-HT2 receptors with an IC50>100 µM. Weak inhibitory effects were observed at sigma opioid receptors. An in vivo study revealed evidence that lamotrigine inhibits Cav2.3 (R-type) calcium currents, which may also contribute to its anticonvulsant effects.

Side Effects

Adult: Dizziness, headache, diplopia, ataxia, nausea, blurred vision, somnolence, rhinitis, pharyngitis, and rash.

Children: Vomiting, diarrhea, infection, fever, abdominal pain, and tremor.

Toxicity

The oral LD50 in mouse and rat is 205 mg/kg and 245 mg/kg, respectively.

Fatal cases of overdose of up to 15g of lamotrigine have been reported. Overdose with lamotrigine has been manifested by ataxia, nystagmus, increased seizures, decreased level of consciousness, coma, and intraventricular conduction delay. Though no known antidote exists for lamotrigine, hospitalization and general supportive measures should be employed in the case of a suspected lamotrigine overdose. Gastric lavage and emesis may be warranted with simultaneous protection of the airway. It is uncertain at this time whether hemodialysis is an effective means of removing lamotrigine from the sytemic circulation.

Precaution

  • Discontinue at the first sign of rash.
  • Blood dyscrasias (e.g., neutropenia, thrombocytopenia, pancytopenia): May occur, either with or without an associated hypersensitivity syndrome. Monitor for signs of anemia, unexpected infection, or bleeding.
  • Suicidal behavior and ideation: Monitor for suicidal thoughts or behaviors.
  • Aseptic meningitis: Monitor for signs of meningitis.

Interaction

  • Valproate increases lamotrigine concentrations more than 2-fold.
  • Carbamazepine, phenytoin, phenobarbital, primidone, and rifampin decrease lamotrigine concentrations by approximately 40%.
  • Estrogen-containing oral contraceptives decrease lamotrigine concentrations by approximately 50%.
  • Protease inhibitors lopinavir/ritonavir and atazanavir/lopinavir decrease lamotrigine exposure by approximately 50% and 32%, respectively.

Food Interaction

  • Take with or without food. The absorption is unaffected by food.

[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 mean apparent volume of distribution (Vd/F) of lamotrigine following oral administration ranges from 0.9 to 1.3 L/kg and is independent of dose administered. Lametec Kid Dt accumulated in the kidney of the male rat, and likely behaves in a similar fashion in humans. Lametec Kid Dt also binds to tissues containing melanin, such as the eyes and pigmented skin.

Elimination Route

Lametec Kid Dt is rapidly and entirely absorbed with minimal first-pass metabolism effects, with a bioavailability estimated at 98%. Cmax is reached in the range of 1.4 to 4.8 hours post-dose, but this depends on the dose administered, concomitant medications, and epileptic status. The rate and extent of lamictal absorption is considered equivalent between the compressed tablet form taken with water to that of the chewable dispersible tablets, taken with or without water.

Half Life

The average elimination half-life of lamotrigine ranges from approximately 14-59 hours. The value is dependent on the dose administered, concomitant drug therapy, as well as disease status. One pharmacokinetic study revealed a half-life of 22.8 to 37.4 hours in healthy volunteers. It also reported that enzyme-inducing antiepileptic drugs such as pheobarbital, phenytoin, or carbamazepine decrease the half-life of lamotrigine. On the other hand, valproic acid increases the half-life of lamotrigine (in the range of 48-59 hours).

Clearance

The mean apparent plasma clearance (Cl/F) ranges from 0.18 to 1.21 mL/min/kg. The values vary depending on dosing regimen, concomitant antiepileptic medications, and disease state of the individual. In one study, healthy volunteers on lamictal monotherapy showed a clearance of about 0.44 mL/min/kg after a single dose.

Elimination Route

Lametec Kid Dt is excreted in both the urine and feces. Following oral administration of 240 mg radiolabelled lamotrigine, about 94% of total drug and its metabolites administered is recovered in the urine and 2% is recovered in the feces. One pharmacokinetic study recovered 43 to 87% of a lamotrigine dose in the urine mainly as glucuronidated metabolites. 2-N-glucuronide is mainly excreted in the urine.

Pregnancy & Breastfeeding use

Either studies in animals have revealed adverse effects on the fetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the fetus.
