Nevertheless, the dosing regimen is adjusted according to a patient’s individual response to pharmacotherapy. The FDA-approved indications and dosages for the use of antidepressant medications in adults are provided in this table. Some of the antidepressant medications are FDA-approved for the treatment of or as adjunct therapy for Parkinson’s disease. This indication is not discussed in this document because of its very specific focus and individualized treatment regimens. All of the antidepressant medications listed are for oral administration unless otherwise stated.

Given their worldwide use, even small risks account for a large number of cases. This study has been conducted with carefully collected information to further investigate the relationship between SSRIs and upper GI bleeding. Methods: We conducted a case-control study in hospitals in Spain and in Italy. Cases were patients aged $18 years with a primary diagnosis of acute upper GI bleeding diagnosed by endoscopy; three controls were matched by sex, age, date of admission (within 3 months) and hospital among patients who were admitted for elective surgery for non-painful disorders. Exposures to SSRIs, other antidepressants and other drugs were defined as any use of these drugs in the 7 days before the day on which upper gastrointestinal bleeding started (index day).

  • Drug Interactions with Antidepressants
    Drug Interactions with Antidepressants These tables contain information on some of the important drug interactions with the SSRIs and other antidepressants. It is not fully comprehensive or inclusive and it is especially important to check out the possibility of an interaction occurring with drug combinations that you are not familiar with. Individual susceptibility and response to a drug interaction can be quite variable and the clinical significance is often approached on a case by case basis. The notes on importance and management give some advice but specialised texts such as Stockley’s should be consulted for detailed information on clinical significance and management. Fluoxetine, paroxetine and citalopram are metabolised by the cytochrome P-450 system in the liver but are substrates for different isoenzymes and vary in their potential to inhibit the metabolism of other drugs. In general, citalopram is less likely to cause drug interactions due to enzyme inhibition than fluoxetine or paroxetine. Drug interactions due to enzyme inhibition or induction are pharmacokinetic drug interactions. SSRIs (and other antidepressants) can also cause pharmacodynamic drug interactions where there is no change in the drug concentration of the interacting drug but the effects are additive or antagonistic due to the drug’s pharmacological properties. Examples include additive sedation with CNS depressants and serotonin syndrome with other serotonergic drugs. In Table 1 “All’ refers to the three SSRIs available in New Zealand; paroxetine, fluoxetine and citalopram. Table 2 refers to TCAs in general although individual drugs have different properties which can increase the risk of an interaction; for example amitriptyline is one of the most sedative TCAs and clomipramine has marked serotonergic properties which increase the risk of serotonin syndrome if given with SSRIs.

Materials and methods: Ninty-four normally potent men, aged 18 ± 61 y (mean 39 y) with premature ejaculation were treated between January 1996 and March 1997, with oral paroxetine hydrochloride, a selective serotonin re-uptake inhibitor (SSRI). All men were either married or in a stable relationship. Sixty-four out of ninety-four men (Group A) were initially treated with paroxetine hydrochloride 20 mg administered once daily. Those men who responded with improved ejaculatory control within four weeks, were then treated with `on-demand' paroxetine hydrochloride (20 mg) administered 3 ± 4 h prior to planned intercourse. The remaining 33 out of 94 men (Group B) were initially treated with `on-demand' paroxetine hydrochloride 20 mg administered 3 ± 4 h prior to planned intercourse. Results: The mean pre-treatment ejaculatory latency time (ELT) of both group A and B was 0.4 min (range 0 ± 1 min) in 205 intercourses at a frequency of 0.4 intercourses PEr week. In group A after four weeks of daily administration of paroxetine, the mean ELT was 4.5 min (range 1- anejac.) in 761 intercourses at a frequency of 2.4 intercourses per week.
