They are particularly used for the management of cardiac arrhythmias, cardiac protection after myocardial infarction (heart attack), and hypertension. Due to these characteristics, the partial antagonists can also be considered as ligands. Working as a nonselective muscarinic acetylcholinergic antagonist, atropine increases firing of the sinoatrial node (SA) and conduction through the atrioventricular node (AV) of the heart, opposes the actions of the vagus nerve, blocks acetylcholine receptor sites, and decreases bronchial secretions. Muscarinic receptor antagonists bind to muscarinic receptors, thereby preventing ACh from binding to and activating the receptor. Adrenergic antagonists are also referred to as sympatholytics because they lyse, or block, the effects of the sympathetic nervous system. Tetanus shots: Is it risky to receive 'extra' boosters?
