Pethidine, also known as meperidine, is a synthetic opioid pain medication. The word is spelled with the letter "e" after the "th" because it is pronounced as a voiceless dental fricative. In IPA, the pronunciation is written as /pɛˈθɪdiːn/ with the "e" representing the /θ/ sound. Pethidine is commonly used for moderate to severe pain relief, but can also cause a range of side effects, including dizziness, nausea, and confusion. It is important to follow dosage instructions carefully and only use this medication as prescribed by a healthcare professional.
Pethidine, also known as meperidine, is a synthetic opioid analgesic used primarily for the relief of moderate to severe pain. It is chemically related to morphine but has a shorter duration of action and a slightly different side-effect profile. Pethidine works by binding to opioid receptors in the central nervous system, inhibiting the transmission of pain signals and producing a numbing effect.
Its mechanism of action involves inhibiting the reuptake of norepinephrine and serotonin, resulting in increased levels of these neurotransmitters in the brain. This dual action distinguishes pethidine from other opioids, making it particularly useful for certain types of pain.
Pethidine is commonly administered intravenously or intramuscularly, with the effects being felt within 15 to 30 minutes. It can also be prescribed in oral or subcutaneous forms. The analgesic effect typically lasts for two to four hours, making it particularly suited for acute pain management.
While pethidine is effective for pain relief, it is also known to have some side effects. These can include dizziness, nausea, vomiting, sedation, and respiratory depression. Prolonged use or high doses of pethidine may lead to physical dependence and addiction. Due to these factors, pethidine is usually not recommended for long-term use or for chronic pain.
Overall, pethidine is a synthetic opioid analgesic commonly used for the relief of moderate to severe pain. It is an effective painkiller but has a shorter duration of action and different side-effect profile compared to other opioids. Close medical supervision is required to ensure safe and appropriate use.
The word "Pethidine" is derived from its chemical name, which is "meperidine". The etymology of "meperidine" can be traced back to the combination of two components: "methyl" and "ethylidine".
The "methyl" component refers to a chemical group consisting of one carbon and three hydrogen atoms (CH3-), which is derived from methane.
The second component, "ethylidine", is derived from "ethyl", another chemical group consisting of two carbon and five hydrogen atoms (C2H5-), and "id-" which indicates "of or pertaining to". When combined with "idine", which is often used to name synthetic drugs, it forms the term "ethylidine".
By combining these two components, the term "meperidine" is formed.
