Abstract

Narcotic analgesics are drugs primarily used to relieve pain. Although narcotic drugs were originally natural products, many new drugs are synthetic. All known narcotic analgesics also produce a number of effects other than analgesia which make them valuable for other clinical uses but also constitute potentials for abuse and narcotic dependence. In addition, there are several pharmacological properties which are characteristic of only a few narcotics and are absent in the rest of them. For example, morphine is known to initially cause vomiting and later show a strong anti-emetic property. All synthetic narcotics are purely anti-emetic and are devoid of the initial emetic action. Similarly, various narcotic analgesics differ in their respiratory depressant property. Whereas they all produce respiratory depression, with some a rapid tolerance develops which allows for further use to relieve pain without concommitant depression of respiration.
