Lexapro (Escitalopram Tablets) and Promethegan rectal
Determining the interaction of Lexapro (Escitalopram Tablets) and Promethegan rectal and the possibility of their joint administration.
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:Consumer information for this interaction is not currently available.MONITOR CLOSELY: Escitalopram can cause dose-dependent prolongation of the QT interval. Theoretically, coadministration with other agents that can prolong the QT interval may result in additive effects and increased risk of ventricular arrhythmias including torsade de pointes and sudden death. In a double-blind, placebo-controlled ECG study consisting of 113 healthy subjects, the change from baseline in QTc (Fridericia-corrected) was 4.3 msec for escitalopram 10 mg/day and 10.7 msec for the supratherapeutic dosage of 30 mg/day. Based on the established exposure-response relationship, the predicted QTc change from placebo under the Cmax for 20 mg/day is 6.6 msec. Cases of QT interval prolongation and torsade de pointes have been reported during postmarketing use. In general, the risk of an individual agent or a combination of agents causing ventricular arrhythmia in association with QT prolongation is largely unpredictable but may be increased by certain underlying risk factors such as congenital long QT syndrome, cardiac disease, and electrolyte disturbances (e.g., hypokalemia, hypomagnesemia). The extent of drug-induced QT prolongation is dependent on the particular drug(s) involved and dosage(s) of the drug(s). In addition, central nervous system- and/or respiratory-depressant effects may be additively or synergistically increased in patients taking escitalopram with certain other drugs that cause these effects, especially in elderly or debilitated patients. MANAGEMENT: Caution is recommended if escitalopram is used in combination with other drugs that can prolong the QT interval. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope. When escitalopram is used in combination with other drugs that cause CNS and/or respiratory depression, patients should be monitored for potentially excessive or prolonged CNS and respiratory depression. Ambulatory patients should be counseled to avoid hazardous activities requiring mental alertness and motor coordination until they know how these agents affect them, and to notify their doctor if they experience excessive or prolonged CNS effects that interfere with their normal activities.
