Interactions between your drugs

Minor

mibefradil ZOLMitriptan

Applies to: Posicor (mibefradil) and zolmitriptan

In vitro studies indicate that mibefradil inhibits the metabolism of drugs that are substrates of the CYP450 1A2 microsomal pathway. This may result in elevated plasma concentrations of these drugs. The manufacturer reports no pharmacokinetic interaction was observed when theophylline, a known substrate of CYP450 1A2, was studied with mibefradil. However, until specific information is available, observation for altered clinical and laboratory effects is recommended if these agents must be used with mibefradil.

Drug and food interactions

Moderate

ZOLMitriptan food

Applies to: zolmitriptan

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
