Although all ssri drugs have the same mechanism of action, each ssri has slightly different pharmacological and pharmacokinetic characteristics this leads to differences among the ssris in their half-lives, clinical activity, side effects, and drug interactions side-effect profile of fluoxetine in comparison with other ssris, tricyclic. Fluoxetine, also known by trade names prozac and sarafem among others, is an antidepressant of the selective serotonin reuptake inhibitor (ssri) class [2] it is used for the treatment of major depressive disorder, obsessive–compulsive disorder (ocd), bulimia nervosa, panic disorder, and premenstrual dysphoric disorderit may decrease the risk of suicide in those over the age of 65.

  • Mechanism of toxicity the toxicity of dothiepin in overdose results from depression of the myocardial function (a quinidine-like effect), anticholinergic activity, alpha adrenergic receptor blockade, and respiratory insufficiency.
  • The same mechanism of action, and any effects will be covered by the new ssri, which should be started at a low dose fluoxetine has a longer half-life than other ssris.
