Combined therapy with anticonvulsant drugs (AEDs) and chemotherapeutic drugs or tyrosine kinase inhibitors carries inherent risks on drug-drug interactions (DDIs). In this review, pharmacokinetic studies of AEDs with chemotherapeutic drugs, tyrosine kinase inhibitors, and glucocorticoids are discussed, including data on maximum tolerated dose, drug clearance, elimination half-life, and organ exposure. Enzyme-inducing AEDs (EIAEDs) cause about a 2-fold to 3-fold faster clearance of concurrent chemotherapeutic drugs metabolized along the same pathway, including cyclophosphamide, irinotecan, paclitaxel, and teniposide, and up to 4-fold faster clearance with the tyrosine kinase inhibitors crizotinib, dasatinib, imatinib, and lapatinib. The use of tyrosine kinase inhibitors, particularly imatinib and crizotinib, may lead to enzyme inhibition of concurrent therapy. Many of the newer generation AEDs do not induce or inhibit drug metabolism, but they can alter enzyme activity by other drugs including AEDs, chemotherapeutics and tyrosine kinase inhibitors. Glucocorticoids can both induce and undergo metabolic change. Quantitative data on changes in drug metabolism help to apply the appropriate dose regimens. clomid for men success stories Some methods of contraception may be less effective in preventing pregnancy for women taking certain anti-epileptic drugs (AEDs). This is because some AEDs (enzyme-inducing AEDs) affect how well methods of contraception work. Non-enzyme-inducing AEDs are unlikely to affect contraception. Enzyme-inducing AEDs may make some methods of contraception less effective. Enzyme-inducing AEDs may affect methods of contraception that contain hormones, such as the Pill or contraceptive implants. This is because they increase the level of enzymes that break down hormones in the body. This means the hormones in contraceptives are broken down more quickly than usual, so they stay in the body for less time and are less effective in preventing pregnancy.

Some anticonvulsants, particularly phenytoin. □ and carbamazepine, induce and increase the production of hepatic enzymes which can result. tamoxifen for dcis Warfarin Interaction With Hepatic Cytochrome P-450 Enzyme-Inducing Anticonvulsants Show all authors. Nathan P. Clark, PharmD, FCCP, BCPS 1 2. Nathan P. To assess the effect of enzyme inducing anticonvulsants on ethosuximide pharmacokinetics, plasma ethosuximide concentrations after a single oral dose 500. Primidone is commonly indicated for the management of grand mal, psychomotor, and focal epileptic seizures [L4645, FDA Label]. In addition, it has also been studied and utilized as an effective management of essential tremor [A39414, A39415, L4645]. For use as monotherapy or adjunctive therapy in the treatment of partial seizures in adults with epilepsy and as adjunctive therapy in the treatment of partial seizures in children ages 4-16 with epilepsy. Used for the treatment and control of partial seizures and severe tonic-clonic (grand mal) seizures and also for the prevention of migraine headaches. In children it is also used for treatment of Lennox-Gastaut syndrome. Qsymia® is indicated for the treatment and management of obesity. The prognoses of seizure treatment with P450 enzyme-inducing and non-enzyme-inducing antiepileptic drugs after glioma resection surgery were investigated across several clinical studies. However, the results of these studies are inconsistent. We examined the relevant studies and conducted a meta-analysis of these two types of anti-epileptic drugs. A bibliography search using the EMBASE, MEDLINE, Clinical Trials.gov, and Cochrane Central Register of Controlled Trials databases was performed to identify potentially relevant articles and conference abstracts that investigated the effects of non-enzyme-inducing antiepileptic drugs (NEIAEDs) and enzyme-inducing antiepileptic drugs (EIAEDs) on the seizure prognoses of glioma patients. One RCT study and five observational studies were included. No significant difference between the efficacies of P450 enzyme-inducing and non-enzyme-inducing antiepileptic drugs for prophylactic late seizure treatment was observed. Pooled estimates of the relative risks (OR) and 95% confidence intervals (CI) were calculated. EIAEDs for patients with glioma was 1.12 (95% CI = 0.70–2.10). EIAEDs for low-grade gliomas was 1.77 (95% CI = 0.71–4.40). However, few RCTs were available, and the acquisition of further evidence through high-quality RCTs is highly recommended.
