Calcium channel blockers

What are calcium channel blockers?

A supplementary, or adjunctive, treatment is administered in conjunction with a patient’s ongoing antipsychotic therapy. Adjunct medications may be prescribed to treat side effects of ongoing antipsychotic medication, and may contribute to increasing adherence to antipsychotic medications and reduce the risk of psychotic relapse. Calcium channel blockers are one such example. However, calcium channel blockers are prescribed with extreme caution due to their potential for extreme side effects, and the dopamine-blocking actions that may interfere or interact with neuroleptic medications.

What is the evidence for calcium channel blockers?

Low quality evidence is unclear of the effect of diltiazem or flunarizine over placebo for tardive dyskinesia.
