Oxcarbazepine/Trileptal is not really a “new” medication. Extended release oxcarbazepine vs Immediate release oxcarbazepine. Significant hyponatremia (sodium < 125 mmol/L) may develop during treatment with oxcarbazepine. MHD is a potent inducer for CYP2C19 (as is CBZ) - at higher doses, oxcarbazepine probably does cause significant inhibition of CYP2C19, with consequent elevations of serum concentrations of phenobarbital and phenytoin. Page Information Overall, 48% of patients had symptoms related to hyponatremia, and in 3% it led to hospital admission. A major advantage of oxcarbazepine is that monitoring of drug plasma levels and hematologic profiles is generally not necessary. Some seniors may be more sensitive to side effects like these. The hyponatremia generally resolves once oxcarbazepine has been discontinued. In a smaller cohort, developing hyponatremia on oxcarbazepine was a risk factor for developing it on carbamazepine. Similar to carbamazepine, oxcarbazepine blocks sodium channels; it does not affect gamma-aminobutyric acid (GABA) receptors. Oxcarbazepine may cause low sodium levels (hyponatremia), usually during the first three months of therapy, although hyponatremia may occur at any time. 1999].This molecular variation results in a different stereoselective metabolism: (1) ESL is not metabolized to carbamazepine-10,11-epoxide (the active metabolite …

Ann. Pharmacology. 2007 Nov;48(11):2116-20.Hyponatremia usually occurs within the fi rst 3 months of therapy, but may happen later if the dose is increased.

Neurology These data suggest, that ESL might share similar efficacy compared to OXC, but with less AEs. For dosing algorithms see Albani F, Bisulli F, Barzaghi M, Because of their differing effects on the CYP enzyme systems, conversion to OXC from CBZ may result in de-induction and an increase in the serum concentration of inducible AEDs.Not routinely done. Side effects considerably worse for adults treated with 1800--2400 mg/day.Overnight conversion is usually well tolerated, especially for patients taking carbamazepine doses of 800 mg/day or less, but many physicians favour a more gradual approach. Eur. OXC and MHD block voltage-gated sodium channels - similar to that of phenytoin and carbamazepine, but MHD has a greater affinity for the inactivated state of the channel2. These medications are not usually taken together. Elderly patients are more susceptible, children less. No fatal cases of CBZ- or OXC-induced hyponatremia have been reported. MHD blocks N- and P-type calcium channels, unlike carbamazepine, which has a greater effect on L-type channels.3. Page History Epilepsia, 35(1), 181--188. Like carbamazepine and oxcarbazepine, ESL has the basic chemical structure of a dibenzazepine nucleus with the 5-carboxamide substituent, but is structurally different at the 10,11-position [Benes et al.

Epilepsia JAMA Neurol It has not been cleared or approved by the Food and Drug Administration. Hyponatremia (sodium < 125 mmol/L) occurred in 2.5% of patients in premarketing clinical trials; however, this generally occurred in patients receiving sodium-depleting diuretics. It’s just an old one, carbamazepine/Tegretol with an oxygen stuck on it. JAMA See, for example, Vendrame M, "Aggravation of seizures and/or EEG features in children treated with oxcarbazepine mono therapy", Epilepsia. If asymptomatic, I prefer NA to be 130 or higher. Resolved comments In patients who have had allergic reactions to carbamazepine, there is a 25 to 30% cross reactivity with oxcarbazepine.
