How do pain killes work?

Answer 1

Painkillers, or analgesics, work by blocking pain signals in the nervous system or by altering the perception of pain in the brain. Nonsteroidal anti-inflammatory drugs (NSAIDs) reduce inflammation and pain by inhibiting enzymes involved in the production of prostaglandins, which are chemicals that promote inflammation. Opioids bind to specific receptors in the brain and spinal cord, effectively blocking the sensation of pain and producing feelings of euphoria. Ultimately, their effectiveness can vary based on the type of pain and the individual’s response to the medication.
