pseudoephedrine rasagiline

Applies to: Pseudo GG (guaifenesin / pseudoephedrine) and rasagiline

MONITOR: Coadministration of nonselective monoamine oxidase (MAO) inhibitors and sympathomimetic amines has been associated with severe hypertensive reactions. The mechanism involves a synergistic sympathomimetic effect due to enhanced norepinephrine storage in adrenergic neurons (MAOI activity) and increased liberation or decreased reuptake of catecholamines (sympathomimetic activity). Concomitant use of sympathomimetic medications was not allowed in clinical studies of rasagiline. Because rasagiline is a selective MAO-B inhibitor, hypertensive reactions would not ordinarily be expected when used with sympathomimetic amines. However, one case of hypertensive crisis has been reported in a patient taking ephedrine with the recommended dosage of a different selective MAO-B inhibitor. In the postmarketing period, elevated blood pressure was reported in a patient using ophthalmic tetrahydrozoline drops while taking the recommended dosage of rasagiline.

MANAGEMENT: Caution is advised if rasagiline is used in combination with sympathomimetic amines. Patients with preexisting hypertension may require more frequent monitoring of their blood pressure.

Drug and food interactions

Moderate

rasagiline food

Applies to: rasagiline

GENERALLY AVOID: Foods that contain large amounts of tyramine may precipitate a hypertensive crisis in patients treated with monoamine oxidase (MAO) inhibitors. The mechanism involves inhibition of MAO-A, the enzyme responsible for metabolizing exogenous amines such as tyramine in the gut and preventing them from being absorbed intact. Once absorbed, tyramine is metabolized to octopamine, a substance that is believed to displace norepinephrine from storage granules. Although rasagiline is a selective inhibitor of MAO-B at the recommended dosages of 0.5 or 1 mg/day, selectivity is not absolute and may diminish with increasing dosage. There were no cases of hypertensive crisis in the clinical development program associated with rasagiline treatment at 1 mg/day, in which most patients did not follow dietary tyramine restriction. However, rare cases of hypertensive crisis have been reported during the postmarketing period in patients who ingested unknown amounts of tyramine-rich foods while taking recommended dosages of rasagiline or selegiline, another MAO-B inhibitor.

Rasagiline peak plasma concentration (Cmax) and systemic exposure (AUC ) are decreased by approximately 60% and 20%, respectively, during coadministration with a high-fat meal. The time to peak concentration (Tmax) is not affected by food.

MANAGEMENT: Dietary restriction is not ordinarily required during rasagiline treatment with respect to most foods and beverages that may contain tyramine such as air-dried and fermented meats or fish, aged cheeses, most soybean products, yeast extracts, red wine, beer, and sauerkraut. However, certain foods like some of the aged cheeses (e.g., Boursault, Liederkrantz, Mycella, Stilton) may contain very high amounts of tyramine and could potentially cause a hypertensive reaction in patients taking rasagiline even at recommended dosages due to increased sensitivity to tyramine. Patients should be advised to avoid ingesting very high levels of tyramine (e.g., greater than 150 mg), and to promptly seek medical attention if they experience potential signs and symptoms of a hypertensive crisis such as severe headache, visual disturbances, confusion, stupor or coma, seizures, chest pain, unexplained nausea or vomiting, and stroke-like symptoms. Rasagiline should not be used at dosages exceeding 1 mg/day (0.5 mg/day for patients with mild hepatic impairment or concomitant use of ciprofloxacin or other CYP450 1A2 inhibitors), as it can increase the risk of hypertensive crisis and other adverse reactions associated with nonselective inhibition of MAO. Rasagiline can be administered with or without food.

pseudoephedrine food

Applies to: Pseudo GG (guaifenesin / pseudoephedrine)

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.

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.
