التداخل بين أولميسارتان وأملوديبين وهيدروكلوروثيازيد وريتونافير

The impact on the PR interval of co-administration of ritonavir with other drugs that prolong the PR interval (including calcium channel blockers, beta-adrenergic blockers, digoxin and atazanavir) has not been evaluated.

Calcium channel blockers: diltiazem, nifedipine, verapamil ↑ calcium channel blockers Caution is warranted and clinical monitoring of patients is recommended.

• Increased amlodipine exposure when coadministered with CYP3A inhibitors Hydrochlorothiazide ( 7.3 ): • Antidiabetic drugs: Dosage adjustment of antidiabetic may be required.

CYP3A Inhibitors: Co-administration of amlodipine with CYP3A inhibitors (moderate and strong) results in increased systemic exposure to amlodipine and may require dose reduction.

Monitor for symptoms of hypotension and edema when amlodipine is co-administered with CYP3A inhibitors to determine the need for dose adjustment.

Blood pressure should be closely monitored when amlodipine is co-administered with CYP3A inducers.

CYP3A Inducers: No information is available on the quantitative effects of CYP3A inducers on amlodipine.
