Compatibility «Itraconazole» and «Clotrimazole»

• Interactions Itraconazole with Clotrimazole

  • Dangerous interactions
    • ⓘ When itraconazole is co-administered with moderate or potent CYP3A4 inducers, the bioavailability of itraconazole and hydroxyitraconazole may decrease, so that efficacy may be reduced.
  • Negative interactions
    • ⓘ Other substances that use this metabolic pathway or alter the activity of CYP3A4 may affect the pharmacokinetics of itraconazole.
    • ⓘ Concomitant use with moderate or potent CYP3A4 inhibitors may increase the bioavailability of itraconazole, leading to more pronounced or prolonged pharmacological effects of itraconazole.
    • ⓘ Itraconazole and its main metabolite hydroxyitraconazole are potent inhibitors of CYP3A4.
    • ⓘ Itraconazole can inhibit the metabolism of drugs metabolized by CYP3A4 and the transport of drugs by P‑glycoprotein and/or BCRP, as a result of which the concentration of these drugs and/or their active metabolites in plasma may increase when taken concomitantly with itraconazole.
    • ⓘ Plasma concentrations decrease more slowly in patients with cirrhosis of the liver or those treated with CYP3A4 inhibitors.
    • ⓘ • CYP3A4 substrates, in which plasma concentrations may increase with prolongation or enhancement of therapeutic and/or undesirable effects until potentially serious situations occur (see the section 'Contraindications').
    • ⓘ • moderate or potent CYP3A4 inducers: administration 2 weeks before and during treatment with itraconazole is not recommended; CYP3A4/P‑gp/BCRP substrates.
    • ⓘ • moderate or potent CYP3A4 inhibitors;.
    • ⓘ • CYP3A4/P‑gp/BCRP substrates for which an increase or decrease in plasma concentrations may lead to a clinically significant risk.
    • ⓘ • CYP3A4 inhibitors (including itraconazole) may increase the concentration of hormonal contraceptives in blood plasma.
    • ⓘ ^a For drugs with arrows in parentheses, the assessment is based on the mechanism of drug interactions and information on clinical drug interactions with ketoconazole or other potent CYP3A4 inhibitors and/or P‑glycoprotein or BCRP inhibitors, as well as data from modeling, clinical cases and/or in vitro experiments.
    • ⓘ Itraconazole and Clotrimazole belong to the same pharmaceutical group: Antifungal agents.
  • Positive interactions
    • ⓘ Rifampicin and phenytoin reduce the bioavailability of itraconazole, cytochrome CYP3A4 inhibitors (ritonavir, indinavir, clarithromycin) increase its bioavailability.
  • Unclear interactions
    • ⓘ Itraconazole is primarily metabolized by CYP3A4.

Decoding the colors of interactions and contraindications

Dangerous	—	a pronounced negative interaction or contraindication.
Negative	—	negative interaction or side effect that may reduce effectiveness.
Positive	—	the interaction can SOMETIMES be used as a positive (often a dose adjustment is needed), or it is an indication of the drug.
No	—	the drugs do NOT interact, which is separately indicated in the instructions.
Unclear	—	the system failed to pre-assess the danger.
