Oxycodone 15 mg is a semi-synthetic opioid analgesic that acts as an agonist at various opioid receptors in the body, including mu, kappa, and delta receptors. Its strongest effect is on mu-type receptors, which play a crucial role in pain relief. This medication is prescribed for the management of moderate to severe pain, particularly when other pain relief options are insufficient. Oxycodone works by blocking the transmission of pain signals in the brain and nervous system, effectively altering the perception of pain and providing significant relief to patients. It is available only with a prescription, reflecting its potency and potential for misuse. Patients may receive oxycodone after surgeries, for chronic pain conditions, or for severe injuries. Due to its effectiveness, it is often considered when other non-opioid pain relievers do not provide adequate relief.
