Analgesic drugs reduce pain by acting on the Central Nervous System (CNS) or Peripheral pain mechanism without affecting consciousness. Analgesics are basically divided into three groups-
Opioid analgesics/ narcotic/morphine-like analgesics- work by changing the perception of pain in the brain.
Non-Opioid analgesics/ anti-inflammatory analgesics- work by lowering the local inflammatory response.
Compound analgesics- are the compound of two analgesics with different mechanisms of action.
Inflammation, Pain such as headache, muscle pain and pain related to arthritis and fractures.
Renal impairment, hepatic impairment.
Prolonged use or irrational use of analgesics may damage internal organs, such as the Liver and Kidney.
Constipation, abdominal discomfort, stomach ulcer, liver damage.
Corticosteroids ( such as prednisone), medication for gout, and anti-seizure drugs.
