Interactions between your drugs

Minor

ramelteon niraparib

Applies to: ramelteon and niraparib

Coadministration with niraparib may decrease the plasma concentrations of drugs that are substrates of the CYP450 1A2 isoenzyme. At high concentrations, niraparib is able to weakly induce CYP450 1A2. If niraparib is used in combination with substrates of CYP450 1A2, particularly those with a narrow therapeutic range (e.g., clozapine, theophylline, ropinirole), then monitoring for signs and symptoms of reduced exposure to the CYP450 1A2 substrate should be considered.

Drug and food interactions

Moderate

ramelteon food

Applies to: ramelteon

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

ADJUST DOSING INTERVAL: Administration of ramelteon with or immediately after a high-fat/heavy meal may delay the onset of hypnotic effects. In study subjects, administration of a 16 mg dose of ramelteon with a high-fat meal decreased the peak plasma drug concentration (Cmax) by 22% and delayed the median time to reach peak plasma drug concentration (Tmax) by approximately 45 minutes compared to administration in a fasted state.

MANAGEMENT: Patients receiving ramelteon should be advised to avoid the consumption of alcohol. For faster sleep onset, ramelteon should not be administered with or immediately after a high-fat/heavy meal.

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.
