Explanation

(i)Neelam expressed values about the safety in choosing analgesics. Whereas non-narcotic analgesics are non-addictive and hence are safe to use, narcotic analgesics are addictive, i.e., habit forming and hence not safe to use. Therefore, narcotic analgesics should be used only in severe pain such as post-operative pain, cardiac pain, pains of terminal cancer and in child birth.
(ii) Examples of non-narcotic analgesics are : aspirin, paracetamol, naproxen, ibuprofen and diclofenac sodium, and examples of narcotic analgesics are morphine, codeine and heroin
(iii) Aspirin acts both as an antipyretic as well as analgesic. Its analgesic action is due to the reason that it inhibits the synthesis of prostaglandins which stimulate inflammation in the tissues and cause pain.
