NIFEdipine budesonide nasal

Applies to: nifedipine and budesonide nasal

MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase the systemic bioavailability of budesonide, which undergoes extensive first-pass and systemic metabolism via intestinal and hepatic CYP450 3A4. In pharmacokinetic studies, 6- to 8-fold increases in budesonide systemic exposure (AUC) have been observed during coadministration of the potent CYP450 3A4 inhibitor ketoconazole with different oral formulations of budesonide. When ketoconazole was administered 12 hours after budesonide in one study, the AUC increase was approximately half that reported during simultaneous administration. In a prospective study of a cystic fibrosis center patient population, 11 of 25 patients receiving high-dose itraconazole (400 to 600 mg/day) and budesonide oral inhalation therapy (800 to 1600 mcg/day) were found to have adrenal insufficiency, including one who developed Cushing's syndrome, compared to none in a group of 12 patients treated with itraconazole alone. There was also no adrenal insufficiency in a group of 30 cystic fibrosis patients retrospectively included as controls, 24 of whom had been treated with high-dose inhaled budesonide for several years. Adrenal function improved, but did not normalize, in 10 of the 11 patients during a follow-up of two to ten months after discontinuation of itraconazole and institution of hydrocortisone replacement therapy. Limited pharmacokinetic data indicate that itraconazole (200 mg once daily) may increase the plasma levels of budesonide by about 4-fold following inhalation of a single 1000 mcg dose, which may be mainly due to increased bioavailability of the swallowed portion of the dose.

MANAGEMENT: The possibility of increased systemic adverse effects of budesonide should be considered during coadministration with CYP450 3A4 inhibitors. If concomitant use cannot be avoided, the dosing times between budesonide and the CYP450 3A4 inhibitor should be separated by as much as possible. In addition, the lowest effective dosage of budesonide should be prescribed, and further adjustments made as necessary according to therapeutic response and tolerance. Patients should be monitored for signs and symptoms of hypercorticism such as acne, striae, thinning of the skin, easy bruising, moon facies, dorsocervical "buffalo" hump, truncal obesity, increased appetite, acute weight gain, edema, hypertension, hirsutism, hyperhidrosis, proximal muscle wasting and weakness, glucose intolerance, exacerbation of preexisting diabetes, depression, and menstrual disorders. Other systemic glucocorticoid effects may include adrenal suppression, immunosuppression, posterior subcapsular cataracts, glaucoma, bone loss, and growth retardation in children and adolescents.

NIFEdipine food

Applies to: nifedipine

GENERALLY AVOID: The consumption of grapefruit juice may be associated with significantly increased plasma concentrations of some calcium channel blockers (CCBs) when they are administered orally. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. The interaction has been reported with the dihydropyridine CCBs (in roughly decreasing order of magnitude) felodipine, nisoldipine, nifedipine, and nimodipine, often with a high degree of interindividual variability. Grapefruit juice caused more than twofold increases in felodipine, nifedipine, and nisoldipine AUCs.

MANAGEMENT: The manufacturers of nifedipine and nisoldipine recommend avoiding grapefruit juice. Patients treated orally with other calcium channel blockers should be advised to avoid consumption of large amounts of grapefruits and grapefruit juice to prevent any undue fluctuations in serum drug levels. Increased effects on blood pressure may persist for up to 4 days after the consumption of grapefruit juice. Monitoring for calcium channel blocker adverse effects (e.g., headache, hypotension, syncope, tachycardia, edema) is recommended.

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.

MONITOR: Calcium-containing products may decrease the effectiveness of calcium channel blockers by saturating calcium channels with calcium. Calcium chloride has been used to manage acute severe verapamil toxicity.

MANAGEMENT: Management consists of monitoring the effectiveness of calcium channel blocker therapy during coadministration with calcium products.

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.
