Edit list (add/remove drugs)

Interactions between your drugs

Moderate

cloNIDine macimorelin

Applies to: Catapres-TTS (clonidine) and Macrilen (macimorelin)

GENERALLY AVOID: Drugs that directly affect the pituitary secretion of growth hormone (e.g., somatostatin, insulin, glucocorticoids, cyclooxygenase inhibitors such as aspirin and nonsteroidal anti-inflammatory drugs) and drugs that may transiently elevate growth hormone levels (e.g., clonidine, levodopa, insulin) may impact the accuracy of the macimorelin diagnostic test.

MANAGEMENT: Concomitant use of macimorelin with drugs affecting growth hormone levels should generally be avoided. A sufficient washout period following discontinuation of these drugs is recommended prior to macimorelin administration.

Drug and food interactions

Moderate

macimorelin food

Applies to: Macrilen (macimorelin)

ADJUST DOSING INTERVAL: Food reduces the oral bioavailability of macimorelin. According to the product labeling, administration with a liquid meal decreased macimorelin peak plasma concentration (Cmax) and systemic exposure (AUC) by 55% and 49%, respectively, compared to administration under fasting conditions (i.e., for at least 8 hours).

MANAGEMENT: Macimorelin should be administered after fasting for at least 8 hours.

MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.

MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.

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.
