بررسی اثرات ایمونولوژیک وراپامیل

Calcium channel blockers are used worldwide in CAD, hypertension and arrhythemia. As recent international studies show these drugs in addition to cardiovascular effects have immunosuppressive effects and can prolong graft life in transplanted patients. In a single blind prospective trial we studied 30 patients on 120 mg/d Verapamil for at least 3 months compared with 15 patients on placebo. Changes of cell immunity markers were impressive as T suppressor lymphocytes increased and CD4/CD8 ratio decreased significantly compared with placebo (P<0.05). This study confirms that Verapamil reduce cell immunity that may prone human beings to infections and on the other side we can use it in hypertensive patients with organ graft.
