NIFEdipine roflumilast topical

Applies to: Nifediac CC (nifedipine) and roflumilast topical

MONITOR: Coadministration with CYP450 3A4 inhibitors or dual CYP450 3A4/1A2 inhibitors may increase the systemic exposure (AUC) to roflumilast following topical administration. According to the prescribing information, N-oxidation of roflumilast by CYP450 3A4 and 1A2 is a major step in the metabolism of the drug. In vitro, roflumilast is 3 times more potent than its N-oxide metabolite at inhibition of the phosphodiesterase 4 (PDE4) enzyme, but on average, the roflumilast N-oxide AUC is approximately 8-fold greater than the parent drug AUC following IV or topical administration and about 10-fold greater following oral administration. In a pharmacokinetic study of 18 adults and 6 adolescents with plaque psoriasis and a mean body surface area involvement of 26.8% (adults) and 13.0% (adolescents), the mean AUC of roflumilast and roflumilast N-oxide following application of 3 to 6.5 g once daily for 15 days was 72.7 and 628 h*ng/mL, respectively, for adults and 25.1 and 140 h*ng/mL, respectively, for adolescents. Data regarding concomitant use of CYP450 3A4 or dual CYP450 3A4/1A2 inhibitors have been reported for oral roflumilast (500 mcg single dose). When coadministered with the potent CYP450 3A4 inhibitor ketoconazole (200 mg twice daily for 13 days), roflumilast peak plasma concentration (Cmax) and AUC increased by 23% and 99%, respectively, while roflumilast N-oxide Cmax decreased by 38% and AUC increased by 3%. When coadministered with erythromycin (500 mg three times daily for 13 days), a moderate CYP450 3A4 inhibitor, roflumilast Cmax and AUC increased by 40% and 70%, respectively, while roflumilast N-oxide Cmax decreased by 34% and AUC increased by 4%. When coadministered with the dual CYP450 3A4/1A2 inhibitors fluvoxamine (50 mg daily for 14 days) or cimetidine (400 mg twice daily for 7 days), roflumilast Cmax increased by 12% and 46% and its AUC increased by 156% and 85%, respectively, while the roflumilast N-oxide Cmax decreased by 210% and 4% and its AUC increased by 52% and 27%, respectively.

MANAGEMENT: Treatment with topical roflumilast should be re-evaluated if an interaction is suspected and persistent intolerability occurs. Patients should be advised to contact their physician if they experience increased frequency and/or severity of side effects such as diarrhea, headache, insomnia, nausea, upper respiratory tract infection, or urinary tract infection.

Applies to: Nifediac CC (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.
