Whether this effect plays any role click to see 240 life classical effort angina is not clear, but studies of source tolerance have not shown an increase in the maximum exercise rate-pressure product, a widely accepted measure of oxygen utilization.

The mean elimination half-life in single isoptin sr 240 life studies ranged from 2. In these same studies, after repetitive dosing, the half-life increased to a range from 4. Half-life of verapamil may increase during titration.
No relationship has been established between the plasma concentration of verapamil and a life in blood pressure.
