Pethidine is the most widely used opioid in labour and delivery. [16] It has fallen out of favour in some countries, such as the United States, in favour of other opioids, due to its potential drug interactions, especially with serotonergics, and its neurotoxic metabolite, norpethidine. [10]
Pethidinic acid (meperidinic acid, pethidine intermediate C) is a 4-phenyl piperidine derivative that is both a metabolite of and a precursor to pethidine (meperidine). [2] [3] It is scheduled by UN Single Convention on Narcotic Drugs. It is a Schedule II Narcotic controlled substance in the United States and has an ACSCN of 9234.
The Passaic Agricultural Chemical Works in Newark, New Jersey, 1876. An agrochemical or agrichemical, a contraction of agricultural chemical, is a chemical product used in industrial agriculture. Agrichemical typically refers to biocides (pesticides including insecticides, herbicides, fungicides and nematicides) alongside synthetic fertilizers.
Norpethidine (normeperidine, pethidine intermediate B) is a 4-phenylpiperidine derivative that is both a precursor to, and the toxic metabolite of, pethidine (meperidine). It is scheduled by UN Single Convention on Narcotic Drugs. It is a Schedule II Narcotic controlled substance in the United States and has an ACSCN of 9233.
Hydroxypethidine (Bemidone) is an opioid analgesic that is an analogue of the more commonly used pethidine (meperidine). Hydroxypethidine is slightly more potent than meperidine as an analgesic, 1.5x meperidine in potency, [2] and it also has NMDA antagonist properties like its close relative ketobemidone.
Agricultural chemistry often aims at preserving or increasing the fertility of soil with the goals of maintaining or improving the agricultural yield and improving the quality of the crop. Soils are analyzed with attention to the inorganic matter (minerals), which comprise most of the mass of dry soil, and organic matter, which consists of ...
Precision Agriculture: The use of GPS and GIS for meticulous field management, with variable rate technology allowing tailored application of resources, optimizing output while minimizing resources.
Piminodine (Alvodine) is an opioid analgesic that is an analogue of pethidine (meperidine). [2] It was used in medicine briefly during the 1960s and 70s, but has largely fallen out of clinical use. It was used particularly for obstetric analgesia and in dental procedures and, like pethidine, could be combined with hydroxyzine to intensify the ...
