ANTIPSYCHOTICS AND CALCIUM-CHANNEL BLOCKERS

Medical Diagnosis and Drugs, Medications
Diltiazem, nifedipine, and verapamil reduce the clearance of sertindole by about 20%. Additive hypotensive effects possible, see antihypertensives.
Concurrent use of these calcium-channel blockers is contraindicated as raised sertindole levels may prolong the QT interval.
