Therapeutic drug levels are lab tests to look for the presence and the amount of a drug in the blood
20 to 332
4-12 mcg/mL (17-51 micromol/L) Toxicity: Adults: > 15 mcg/mL (> 63 micromol/L) Cardiac Effects: dysrhythmias and conduction defects may occur at levels as low as 3
Also known as Tegretol
Future research should also focus on the role of both norclozapine and clozapine-N-oxide levels in therapeutic drug monitoring, and the relevance of specific cytochrome P450 enzymes monitoring in drug-drug interactions

Oxcarbazepine is a medication used in the treatment of partial seizures
carbamazepine will decrease the level or effect of sofosbuvir/velpatasvir by affecting hepatic/intestinal enzyme CYP3A4 metabolism
Then, carbamazepine levels should be monitored every two to three months thereafter or after a CYP3A4 inhibitor/inducer is added
0 mcg/mL (even though the total carbamazepine concentration is <15

The risk of SJS or TEN is highest in people of Asian ancestry who have a genetic (inherited) risk factor
Much of the drug is bound to proteins in the blood plasma, but it is the free portion of the drug that has the therapeutic effect
Adults—100 milligrams (mg) or 1 teaspoon 4 times a day (400 mg per day)
The primary metabolite of oxcarbazepine is monohydroxylated derivative (MHD)
0 mcg/mL or higher and is typified by irregular breathing, muscle irritability, and hyperreflexia; followed by hyporeflexia, tachycardia, hypotension, and impaired consciousness with coma in severe toxicity
