procarbazine SUMAtriptan

Applies to: procarbazine and Imitrex (sumatriptan)

CONTRAINDICATED: Monoamine oxidase inhibitors (MAOIs) may significantly elevate the plasma concentrations of certain 5-HT1 receptor agonists (namely rizatriptan, sumatriptan, and zolmitriptan) and their active metabolites by inhibiting their metabolic clearance via monoamine oxidase, subtype A. Clinically, this interaction may increase the risk of vasospastic reactions, including coronary artery vasospasm, peripheral vascular ischemia and colonic ischemia, associated with the use of 5-HT1 receptor agonists. Although the pharmacokinetic alterations are observed only with a limited number of 5-HT1 receptor agonists and their metabolites, the possibility of a pharmacodynamic interaction should be considered for all agents in the class, since they exhibit modest 5-HT1A activity. Theoretically, MAOIs may potentiate the serotonergic activity of these agents and increase the risk of serotonin syndrome, which is a rare but serious and potentially fatal condition thought to result from hyperstimulation of brainstem 5-HT1A and 2A receptors. The mechanism is inhibition of the breakdown of serotonin by MAOIs. Symptoms of the serotonin syndrome may include mental status changes such as irritability, altered consciousness, confusion, hallucinations, and coma; autonomic dysfunction such as tachycardia, hyperthermia, diaphoresis, shivering, blood pressure lability, and mydriasis; neuromuscular abnormalities such as hyperreflexia, myoclonus, tremor, rigidity, and ataxia; and gastrointestinal symptoms such as abdominal cramping, nausea, vomiting, and diarrhea.

MANAGEMENT: Concomitant use of rizatriptan, sumatriptan, or zolmitriptan with MAOIs or other agents that possess MAOI activity (e.g., furazolidone, linezolid, methylene blue, procarbazine) is considered contraindicated. At least 14 days should elapse between discontinuation of MAOI therapy and initiation of treatment with 5-HT1 receptor agonists. If concurrent therapy is necessary, almotriptan, frovatriptan and naratriptan may be preferred due to the lack of a significant pharmacokinetic interaction with MAOIs. However, patients should be closely monitored for adverse effects related to excessive serotonergic activity.

Drug and food interactions

Major

procarbazine food

Applies to: procarbazine

CONTRAINDICATED: Foods that contain large amounts of tyramine may precipitate a hypertensive crisis in patients treated with monoamine oxidase inhibitors (MAOIs). The mechanism is 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.

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

MANAGEMENT: In general, patients treated with MAOIs or other agents that possess MAOI activity (e.g., furazolidone, linezolid, procarbazine) should avoid consumption of products that contain large amounts of amines and protein foods in which aging or breakdown of protein is used to increase flavor. These foods include cheese (particularly strong, aged or processed cheeses), sour cream, wine (particularly red wine), champagne, beer, pickled herring, anchovies, caviar, shrimp paste, liver (particularly chicken liver), dry sausage, salamis, figs, raisins, bananas, avocados, chocolate, soy sauce, bean curd, sauerkraut, yogurt, papaya products, meat tenderizers, fava bean pods, protein extracts, yeast extracts, and dietary supplements. Caffeine may also precipitate hypertensive crisis so its intake should be minimized as well. At least 14 days should elapse following discontinuation of MAOI therapy before these foods may be consumed. Specially designed reference materials and dietary consultation are recommended so that an appropriate and safe diet can be planned. Patients should be advised to promptly seek medical attention if they experience potential signs and symptoms of a hypertensive crisis such as severe headache, visual disturbances, difficulty thinking, stupor or coma, seizures, chest pain, unexplained nausea or vomiting, and stroke-like symptoms. Patients should also be counseled not to use MAOIs with alcohol, and to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them.

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.
