Prelidopine Pre-Operative System and Seconal Sodium

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

Coadministration with barbiturates may decrease the plasma concentrations of lidocaine. The proposed mechanism is induction of lidocaine metabolism via CYP450 3A4. In four healthy volunteers (2 smokers and 2 nonsmokers), administration of a single 400 mg oral dose of lidocaine following pretreatment with phenobarbital (15 mg/day for 4 weeks, followed by 30 mg/day for 4 weeks) decreased lidocaine systemic exposure (AUC) by 37% and increased its oral clearance by 56% compared to administration of lidocaine alone. In another study, the mean bioavailability of a single 750 mg oral dose of lidocaine in six patients receiving chronic antiepileptic drug therapy (consisting of one or more of the following enzyme-inducing anticonvulsants: phenobarbital, primidone, phenytoin, carbamazepine) was approximately 2.5-fold lower than that reported for six healthy control subjects, while intrinsic clearance was nearly threefold higher. By contrast, the interaction was modest for lidocaine administered intravenously, suggesting induction of primarily hepatic first-pass rather than systemic metabolism of lidocaine. When a single 100 mg dose of lidocaine was given intravenously, mean lidocaine AUC was reduced by less than 10% and serum clearance increased by just 17% in the epileptic patients compared to controls. These changes were not statistically significant. Because lidocaine is not available commercially for oral administration, the interaction may be of limited clinical relevance.
