Morphine, formerly also called morphia, is a strong opiate that is found naturally in opium, a dark brown resin produced by drying the latex of opium poppies. It is mainly used as an analgesic. There are numerous methods used to administer morphine: oral; sublingual; via inhalation; injection into a muscle, injection under the skin, or injection into the spinal cord area; transdermal; or via rectal suppository. It acts directly on the central nervous system (CNS) to induce analgesia and alter perception and emotional response to pain. Physical and psychological dependence and tolerance may develop with repeated administration. It can be taken for both acute pain and chronic pain and is frequently used for pain from myocardial infarction, kidney stones, and during labor. Its maximum effect is reached after about 20 minutes when administered intravenously and 60 minutes when administered by mouth, while the duration of its effect is 3–7 hours. Long-acting formulations of morphine are available as MS-Contin, Kadian, and other brand names as well as generically.

ਮਾਰਫ਼ੀਨ (Morphine) ਇੱਕ ਅਲਕਾਲਾਈਡ ਹੈ। ਸਰਟਰਨਰ ਨੇ 1806 ਵਿੱਚ ਇਸ ਨੂੰ ਅਫ਼ੀਮ ਤੋਂ ਤਿਆਰ ਕੀਤਾ ਸੀ। ਇਸ ਦੀ ਵਰਤੋਂ ਹਾਇਡਰੋਕਲੋਰਾਈਡ, ਸਲਫੇਟ, ਏਸੀਟੇਟ, ਟਾਰਟਰੇਟ ਅਤੇ ਹੋਰ ਸੰਯੋਜਕਾਂ ਦੇ ਰੂਪ ਵਿੱਚ ਹੁੰਦੀ ਹੈ। ਇਹ ਇੱਕ ਪੀੜ ਨਿਵਾਰਕ ਹੈ ਅਤੇ ਇਸ ਨਾਲ ਗੂੜੀ ਨੀਂਦ ਆਉਂਦੀ ਹੈ।
