Encourage Prescribers to Write Long-Acting Calcium Channel Blockers Generically

It can be confusing to sort through the long-acting calcium channel blockers...Adalat XL, Cardizem CD, Tiazac XC, etc.

Use these rules of thumb to help keep the extended-release formulations of diltiazem and nifedipine straight.
