Generic vs brand: There's no difference in the drug but the delivery may differ. The CD is always a 24 hour preparation. The ER version may be either 12 hour or 24 hour, so you must read your label or check with your pharmacist.. The 12 hour versions are generally smaller mg doses (60, 90, or 120 mg) while the 24 hour is usually 120 mg or higher.

ER stands for extended-release and CD stands for controlled delivery. Both medications are usually taken once a day. However, the diltiazem ER product may say “12-hour” or “24-hour”; if it’s the “12-hour” product, it’s usually taken twice a day, while the “24-hour” product is usually just once a day. So it depends on the specific diltiazem ER product a person has.

Pharmacokinetics: CArdizem CD basically is long acting. Typically this form is to be taken once/day as it is supposed to give you coverage for 24 hours. The other one, by "we" I think you mean short-acting Cardizem (typically comes in 30 mg and 60 mg tablets), is short-acting, and faster acting, but out of systems usually within 6 hrs, so in some cases can be give three or 4 times/day. Active ingredient same.
