Abstract:
Affective disorders and impulsivity are quite common when using anabolic substances, in this case-study one of the rather rare cases of a psychotic disorder following the abuse of androgenic steroids is described. A 30-year old formerly healthy white male was admitted as inpatient to psychiatric hospital showing symptoms of anxiety and paranoid ideation. In the last 1.5 years he had consumed androgenic steroids, directly before the onset of the first psychotic symptoms 8 weeks before admission he had received an i.m.-injection of nandrolone. Under therapy with neuroleptics the patient recovered completely within 2 months.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
