Anticholinergics mechanism of action in bronchodilation
Some additional information from Goodman & Gilman’s Anticholinergic Agents With the advent of inhaled beta adrenergic agonists, use of anticholinergic agents declined. Renewed interest in anticholinergic agents paralleled the realization that parasympathetic pathways are important in bronchospasm in some asthmatics and the availability of ipratropium bromide (ATROVENT), a quaternary muscarinic receptor antagonist that has better […]
Beta lactams antibiotics (penicillins and cephalosporins) mechanism of action: videos and animations
Mechanism of action of the beta lactam antibiotics (penicillins and cephalosporins) The beta-lactam antibiotics can kill susceptible bacteria. Although knowledge of the mechanism of this action is incomplete, numerous researchers have supplied information that allows understanding of the basic phenomenon (seeGhuysen, 1991; Bayles, 2000). The cell walls of bacteria are essential for their normal growth […]
