CR – controlled release. This means that the drug has a constant rate of release. DR – delayed release. This generally refers to enteric- coated tablets which are designed to release the drug in the intestine where the pH is in the alkaline range. ER – extended release. Dosage forms which are designed to release the drug over an extended period of time, such as implants which release the drug over a period of months or years. SA – sustained action. Used interchangeably with CR (above), except that SA usually refers to the pharmacologic action while CR refers to the drug release process. TD – time delayed. This is slightly different from DR in that the drug release is designed to occur after a certain period of time, such as pellets coated to a certain thickness, multi-layered tablets, tablets within a capsule, or double-compressed tablets.
