Interactions between your drugs

Moderate

cinacalcet sofpironium topical

Applies to: cinacalcet and sofpironium topical

GENERALLY AVOID: Coadministration with potent inhibitors of CYP450 2D6 may significantly increase the plasma concentrations of topical sofpironium, which has been shown to be partially metabolized by the isoenzyme. In a pharmacokinetic study in patients with primary axillary hyperhidrosis, sofpironium systemic exposure (AUC) and peak plasma concentration (Cmax) increased approximately 2 -fold following concomitant use with the potent CYP450 2D6 inhibitor paroxetine at a 20 mg oral dose.

MANAGEMENT: Coadministration of topical sofpironium with potent CYP450 2D6 inhibitors should generally be avoided. If coadministration is required, monitor for sofpironium-related adverse effects which include blurred vision, urinary retention, difficulty controlling body temperature in warm environments, and dry mouth.

Drug and food interactions

Moderate

cinacalcet food

Applies to: cinacalcet

ADJUST DOSING INTERVAL: Food enhances the oral absorption and bioavailability of cinacalcet. According to the product labeling for cinacalcet, administration with a high-fat meal increased the peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of cinacalcet by 82% and 68%, respectively, compared to administration in the fasting state. The Cmax and AUC were increased 65% and 50%, respectively, when cinacalcet was administered with a low-fat meal compared to fasting.

MANAGEMENT: To ensure maximal oral absorption, cinacalcet should be administered with or immediately after a meal. The tablets should be taken whole and not divided or crushed.

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.
