A CR tablet is a type of controlled-release (CR) medication in tablet form. The term "controlled-release" refers to the gradual release of the active drug over an extended period of time, allowing for a lower frequency of dosing and more consistent therapeutic levels in the body. CR tablets are designed to dissolve slowly in the body, releasing the drug over a prolonged period of time, often 12-24 hours. This allows for a lower and more consistent blood level of the drug, reducing the risk of side effects and increasing the efficacy of the treatment. CR tablets are commonly used for a variety of conditions, including pain management, hypertension, and psychiatric disorders. It is important to follow the instructions on the label and to take the medication exactly as prescribed by a healthcare provider.
