Itraconazole Capsules (Sporanox) and Topcare Complete Acid Reducer plus Antacid
Determining the interaction of Itraconazole Capsules (Sporanox) and Topcare Complete Acid Reducer plus Antacid and the possibility of their joint administration.
In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.
Consumer:Taking itraconazole and famotidine too close together may interfere with the absorption of itraconazole and reduce its effectiveness. To prevent or minimize the interaction, itraconazole should be taken at least two hours before or one hour after famotidine. Taking itraconazole with a cola beverage may also help by increasing stomach acid. Contact your doctor if your infection does not improve or gets worse. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:ADJUST DOSING INTERVAL: Oral H2 antagonists may significantly decrease the plasma concentration of oral itraconazole capsules. The mechanism is related to an increase in gastric pH resulting in a decrease in absorption of the antifungal. Clinical monitoring of patient response is recommended.
MANAGEMENT: H2 antagonists should be taken at least 2 hours after itraconazole. If necessary, an acidic pH may be produced by administration with an acidic beverage such as Coca-Cola(R) or Pepsi(R). However, clinicians should still consider the possibility of a reduced or subtherapeutic antifungal effect. It may be appropriate to switch to itraconazole oral solution or an agent like fluconazole or terbinafine whose absorption is not affected by stomach pH.
