Drug Name Lotensin

Pathophysiology. One of the main pathogenetic factors is an allergic inflammation of the bronchial mucosa. For instance, leukotrienes that are formed during an IgE-mediated immune response exert a chemotactic effect on inflammatory cells. As the inflammation develops, bronchi become hypersensitive to spasmogenic stimuli.
Altered activity of transport systems affects cell function (e.g., cardiac glycosides; loop diuretics; calcium-antagonists). Drugs may also directly interfere with intracellular metabolic processes, for instance by inhibiting (phosphodiesterase inhibitors) or activating (organic nitrates) an enzyme.

 

All benzodiazepines exert their actions at specific receptors (p. 226). The choice between different agents is dictated by their speed, intensity, and duration of action. These, in turn, reflect physicochemical and pharmacokinetic properties. Individual benzodiazepines remain in the body for very different lengths of time and are chiefly eliminated through biotransformation.
Furthermore, safety profiles may be improved for drugs that produce significant amounts of toxic metabolites mediated by first-pass liver metabolism and gastric metabolism, and for drugs that have a substantial fraction of absorption in the oral cavity and pregastric segments of GIT22.
