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 […]
Cisplatin mechanism of action: 3-D video animation
Mechanism of Action. Cisplatin, carboplatin, and oxaliplatin enter cells by diffusion, and by an active Cu2+ transporter (Kruh, 2003). Inside the cell, the chloride atoms of cisplatin may be displaced and the compound may be inactivated directly by reaction with nucleophiles such as thiols. Chloride is replaced by water, yielding a positively charged molecule. In […]

Animation: insulin secretion and sulfonylureas mechanism of action
Animation that depicts how sulfonylureas enhance insulin secretion by binding to specific beta cell receptors. Download available
DPP-4 inhibitors: consensus statement published on Diabetes Care. Diagram of its mechanism of action.
Below is a transcript of the latest statement (December 2008) published on Diabetes Care about the role of dipeptidyl peptidase four inhibitors in the medical management of hyperglycemia in type 2 diabetes. Dipeptidyl peptidase four inhibitors. GLP-1 and glucose-dependent insulinotropic peptide (GIP), the main insulinotropic peptides of intestinal origin (incretins), are rapidly degraded by dipeptidyl peptidase four (DPP-4). […]
