Answer: D - Miperidine is an analgesic opioid agonist.
Meperidine is a synthetic opioid drug that is used to relieve moderate to severe pain. It works as an analgesic by binding to specific opioid receptors in the brain and spinal cord, which are responsible for transmitting pain signals. When meperidine binds to these receptors, it can reduce the transmission of pain signals and produce a feeling of euphoria.
Meperidine is an agonist of the mu opioid receptor, whe of three types of opioid receptors in the body. Activation of the mu opioid receptor produces a variety of effects, including pain relief, sedation, and respiratory depression. Meperidine is also a relatively potent analgesic, with effects similar to morphine.
Because meperidine has a relatively short half-life compared to other opioid drugs, it is often used for short-term pain relief, such as during surgery or childbirth. However, it has a higher risk of adverse effects, such as respiratory depression and potential for addiction, so its use is generally limited to specific situations and under careful medical supervision.
All the drugs listed except miperidine are used to treat tuberculosis.
