Calcium channel blockers may increase risk of suicide

A recent study suggested an excess risk of depression with calcium channel blockers. Lindberg et al (p 741) therefore investigated the risk of suicide associated with cardiovascular drugs, with special reference to calcium channel blockers. In a cross sectional ecological study of 152 Swedish municipalities they found a significant correlation between the use of calcium channel blockers and the incidence of suicide. In a population based cohort study of subjects who purchased various antihypertensive drugs in 1988-9 they then found a fivefold increase in the incidence of suicide in users of calcium channel blockers compared with non-users during follow up until the end of 1994.
