Isonipecotic Acids
Medical Definition: |
Diphenoxylate - A MEPERIDINE congener used as an antidiarrheal, usually in combination with atropine. At high doses, it acts like morphine. Its unesterified metabolite difenoxin has similar properties and is used similarly. It has little or no analgesic activity. | |
Meperidine - A narcotic analgesic that can be used for the relief of most types of moderate to severe pain, including postoperative pain and the pain of labor. Prolonged use may lead to dependence of the morphine type; withdrawal symptoms appear more rapidly than with morphine and are of shorter duration. | |
Phenoperidine - A narcotic analgesic partly metabolized to meperidine in the liver. It is similar to morphine in action and used for neuroleptanalgesia, usually with droperidol. | |
Pirinitramide - A diphenylpropylamine with intense narcotic analgesic activity of long duration. It is a derivative of MEPERIDINE with similar activity and usage. |
