aspirin salicylamide

Applies to: aspirin / caffeine / salicylamide and aspirin / caffeine / salicylamide

MONITOR: The combined use of low-dose or high-dose aspirin with other nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the potential for serious gastrointestinal (GI) toxicity, including inflammation, bleeding, ulceration, and perforation. Aspirin at anti-inflammatory dosages or higher may also decrease the plasma concentrations of many NSAIDs. The decreases have ranged from none or small (piroxicam, meloxicam, naproxen, tolmetin) to substantial (flurbiprofen, ibuprofen). However, the therapeutic response does not appear to be affected. Investigators theorize that aspirin may displace NSAIDs from plasma protein binding sites, resulting in increased concentration of unbound, or free, drug available for clearance. The increase in NSAID free fraction, and possibly some contributory anti-inflammatory effect from aspirin, may account for the lack of overall effect on therapeutic response.

MANAGEMENT: Caution is advised if aspirin, particularly at anti-inflammatory dosages, is used with other NSAIDs. Concomitant administration of NSAIDs is considered contraindicated or not recommended with aspirin at analgesic/anti-inflammatory dosages by many NSAID manufacturers. During concomitant therapy, patients should be advised to take the medications with food and to immediately report signs and symptoms of GI ulceration and bleeding such as abdominal pain, bloating, sudden dizziness or lightheadedness, nausea, vomiting, hematemesis, anorexia, and melena.

caffeine rasagiline

Applies to: aspirin / caffeine / salicylamide and rasagiline

ADJUST DOSE: Coadministration with inhibitors of CYP450 1A2 may increase the plasma concentrations of rasagiline, which is primarily metabolized by the isoenzyme. In 12 healthy volunteers, administration of rasagiline (2 mg/day) with the moderate CYP450 1A2 inhibitor ciprofloxacin (500 mg twice a day) resulted in an 83% increase in rasagiline systemic exposure (AUC), with no change in elimination half-life. Because the MAO-B selectivity of rasagiline may diminish with increasing dosage above the recommended range of 0.5 to 1 mg/day, there may be an increased risk of hypertensive crisis and other adverse reactions associated with nonselective inhibition of MAO if the maximum dosage is used in the presence of ciprofloxacin. The interaction has not been studied with other, less potent CYP450 1A2 inhibitors.

MANAGEMENT: In patients receiving CYP450 1A2 inhibitors, it may be appropriate to initiate therapy at 0.5 mg/day, then increase gradually as needed and as tolerated. 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, confusion, stupor or coma, seizures, chest pain, unexplained nausea or vomiting, and stroke-like symptoms.

aspirin caffeine

Applies to: aspirin / caffeine / salicylamide and aspirin / caffeine / salicylamide

One study has reported that coadministration of caffeine and aspirin lead to a 25% increase in the rate of appearance and 17% increase in maximum concentration of salicylate in the plasma. A significantly higher area under the plasma concentration time curve of salicylate was also reported when both drugs were administered together. The exact mechanism of this interaction has not been specified. Physicians and patients should be aware that coadministration of aspirin and caffeine may lead to higher salicylate levels faster.

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.

aspirin food

Applies to: aspirin / caffeine / salicylamide

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

Applies to: aspirin / caffeine / salicylamide

The effect of grapefruit juice on the pharmacologic activity of caffeine is controversial. One report suggests that grapefruit juice increases the effect of caffeine. The proposed mechanism is inhibition of cytochrome P-450 metabolism of caffeine. However, a well-conducted pharmacokinetic/pharmacodynamic study did not demonstrate this effect. The clinical significance of this potential interaction is unknown.
