Alprazolam
SSRIs and the benzodiazepine alprazolam are often used to treat panic disorder. Pharmacokinetic reactions between them could therefore be important. Alprazolam is metabolized by CYP3A4, which fluvoxamine inhibits [154]. In 23 out-patients (11 men, 12 women, mean age 39 years) who took alprazolam both as monotherapy (mean dose 1.0 mg/day) and in combination with fluvoxamine (mean dose 34 mg/day), fluvoxamine increased plasma alprazolam concentrations by 58% [159]. This was not associated with increased sleepiness, measured by a subjective rating scale, but objective measures of psychomotor function were not carried out and these could have been impaired by raised alprazolam concentrations.

The effects of SSRIs on alprazolam pharmacokinetics have been studied in 21 healthy volunteers (age and sex not given) who were pre-treated with either fluoxetine or citalopram (20 mg/day for 21 days) [160]. Fluoxetine increased the AUC of a single 1.0 mg dose of alprazolam by 32%; citalopram had no effect. These findings are consistent with previous reports that fluoxetine and its active metabolite, norfluoxetine, produce moderate inhibition of CYP3A4 while citalopram does not.

Endocrine
Alprazolam can alter dehydroepiandrosterone and cortisol concentrations. Of 38 healthy volunteers who received a single intravenous dose of alprazolam 2 mg over 2 minutes (phase I), 15 of 25 young men (aged 22–35 years) and all 13 elderly men (aged 65–75 years) responded to alprazolam and agreed to participate in a crossover study of placebo and alprazolam infusion to plateau for 9 hours (15). Plasma samples at 0, 1, 4, and 7 hours were assayed for steroid concentrations. Alprazolam produced: Buy Alprazolam Pfizer Xanax 2mg online in Australia
- (a)
-
significant increases in dehydroepiandrosterone concentrations at 7 hours in both the young and elderly men;
- (b)
-
significant reductions in cortisol concentrations;
- (c)
-
no change in dehydroepiandrosterone-S concentrations.
The results suggest that alprazolam modulates peripheral concentrations of dehydroepiandrosterone and that dehydroepiandrosterone and/or dehydroepiandrosterone-S may have an in vivo role in modulating GABA receptor-mediated responses. Buy Alprazolam Pfizer Xanax 2mg online in Australia

Placebo-controlled studies
Alprazolam 0.25 mg or 1 mg has been evaluated in 47 otherwise healthy subjects, selected for a moderate to high degree of anxiety before oral surgery in a three-arm, parallel design, double-blind, randomized, placebo-controlled study [10]. There were 27 adverse events in the interval between dosing and surgery: 2, 10, and 15 events each with placebo, alprazolam 0.25 mg and alprazolam 1 mg respectively. The most common events were drowsiness with placebo and drowsiness, dizziness, lightheadedness, and nausea with alprazolam. There were also single reports of trembling, feeling cold, anxiety, panic attacks, a desire to smoke, increased appetite, sleepiness, and dry mouth with alprazolam. There were no serious adverse events and no subject withdrew from the study because of adverse events. Buy Alprazolam Pfizer Xanax 2mg online in Australia
