Flamrase SR is a sustained-release medication primarily used for its anti-inflammatory and analgesic properties. The "SR" in its name stands for "sustained release," indicating that the drug is formulated to release its active ingredient slowly over time to provide prolonged relief from symptoms. Flamrase SR contains diclofenac, a nonsteroidal anti-inflammatory drug (NSAID) that works by reducing substances in the body that cause pain and inflammation. It is commonly prescribed to treat conditions such as arthritis, menstrual pain, and other types of acute pain. As with other NSAIDs, it is important for patients to take Flamrase SR under the guidance of a healthcare provider due to potential side effects and interactions with other medications.
