11 Examples of Controlled Release Products
• LA-long acting – Entex LA • SA-sustained action-Depronal SA • SR-sustained release – Cardizem SR • CR-controlled release –Epilim CR • TR-timed release- Melatonin TR • CD-controlled dissolution – Cardizem CD • ER-extended release- Zohydro ER, Razadyne ER • XL-extended release – Procardia XL • XR-extended release – Dilacor XR, Xanax XR Examples of Controlled Release Products
