Drug Name Lotensin

The eicosanoids, prostaglandins, thromboxane, prostacyclin, and leukotrienes, are formed in the organism from arachidonic acid, a C20 fatty acid with four double bonds (eicosatetraenoic acid). Arachidonic acid is a regular constituent of cell membrane phospholipids; it is released by phospholipase A2 and forms the substrate of cyclooxygenases and lipoxygenases.
The substances listed below are useful as antibacterial drugs because they do not affect human cells. Gyrase inhibitors. The enzyme gyrase (topoisomerase II) permits the orderly accommodation of a ~1000 ?mlong bacterial chromosome in a bacterial cell of ~1 ?m. Within the chromosomal strand, double-stranded DNA has a double helical configuration.

 

Originally, anesthetization was achieved with a single anesthetic agent (e. g. , diethylether— first successfully demonstrated in 1846 by W. T. G. Morton, Boston). To suppress defensive reflexes, such a “mono-anesthesia” necessitates a dosage in excess of that needed to cause unconsciousness, thereby increasing the risk of paralyzing vital functions, such as cardiovascular homeostasis (B).
Clofibrate and derivatives (bezafibrate, etofibrate, gemfibrozil) lower plasma lipids by an unknown mechanism. They may damage the liver and skeletal muscle (myalgia, myopathy, rhabdomyolysis). Probucol lowers HDL more than LDL; nonetheless, it appears effective in reducing atherogenesis, possibly by reducing LDL oxidation.
