Studies examining the link between sexual dysfunction and tricyclic antidepressants have noted an overall rate in sexual dysfunction was approximately 30% of men on these medications. He noted that the overall rate in sexual dysfunction was approximately 30% for men taking imipramine. A more recent study estimated the overall rate of sexual dysfunction from tricyclic antidepressants at 60%. One...

Clinical features and drug plasma concentrations were studied in 13 children admitted to hospital with tricyclic antidepressant poisoning. Patients with plasma concentrations below 500 microgram/l had anticholinergic signs and increased reflexes but did not have convulsions or cardiac arrhythmias. Four patients with plasma concentrations above 1000 microgram/l suffered convulsions, cardiac arrh...

Evidence of cardiovascular toxicity is present in the majority of tricyclic antidepressant overdoses. We report the case of a 63-year-old woman admitted to our department with a severe amitriptyline poisoning. The ECG at admission showed a pattern mimicking an acute anteroseptal subepicardial infarction. This pattern persisted for 11 days. Myocardial enzymes and echocardiographic findings never...

We examined the effects of minaprine and sulpiride injected into the medial amygdaloid nucleus on the duration of immobility in rats forced to swim. Minaprine (50 micrograms/microliter) significantly reduced the duration of immobility, while sulpiride (50 micrograms/microliters) remarkedly enhanced it. These results suggest that the medial amygdaloid nucleus might be involved in the suppressive...

Eleven patients who had taken overdoses of barbiturates, glutethimide, tricyclic antidepressants, and chloroquine were treated by resin haemoperfusion using an R-004 haemoperfusion cartridge containing XAD-4 resin. All but one patient showed rapid clinical recovery and the drugs were cleared rapidly from the plasma. There were few complications. Resin haemoperfusion is more effective than dialy...

The title compound {systematic name: 1-[(1R,4aS,10aR)-7-isopropyl-1,2,3,4,4a,9,10,10a-octa-hydro-phenanthren-1-yl]-N-[(E)-2-pyridylmethyleneamino]methanamine}, C(26)H(33)N(2), has been synthesized from dehydro-abietylamine. The two cyclo-hexane rings form a trans ring junction with classic chair and half-chair conformations, respectively, whereas the benzene and pyridine rings are almost planar...

Azaphilone derivatives 1 and 2 and a novel tricyclic polyketide 3, together with a known azaphilone, austdiol (4), were isolated from the endophytic fungus Dothideomycete sp., which was isolated from a Thai medicinal plant, Tiliacora triandra. Compound 3 is the first polyketide having a tricyclic 6,6,6 ring system, which is similar to that of a terpenoid skeleton. The absolute configurations of...

The cardiotoxicity of the tricyclic antidepressants amitriptyline and doxepin were compared in an animal with acute overdose. The mean repetitive extrasystole threshold (RET) decreased 71.5% with amitriptyline and 27.5% with doxepin (mean blood levels 933 ng/ml and 1889 ng/ml). Physostigmine reversed these effects. Sodium bicarbonate had a variable effect on the lowered RET. The toxic arrhythmo...

Herbarin (I) and dehydroherbarin (II) isolated from the fungus Torula herbarum (Pers.)1} possess weak antimicrobial activity and belong to the class of pigments in which a naphthaquinone moiety is fused to an oxacyclohexene ring at the 1,2-positions. The first compounds characterized in this class were javanicin (III) and fusarubin (also called oxyjavanicin) (IV) from the fungus Fusarium javani...

The Saccharomyces cerevisiae ERG7(Phe699) mutants produced one chair-chair-chair (C-C-C) and two chair-boat-chair (C-B-C) truncated tricyclic compounds, one tetracyclic 17alpha-exocyclic unrearranged intermediate, and two 17beta-exocyclic truncated rearranged intermediates. These results provided direct evidence for the importance of the residue in affecting mechanistic transitions between C-B-...
