Efficacy and Safety of Doxepin 1 mg, 3 mg, and 6 mg in Adults with Primary Insomnia
The antidepressant effect of doxepin is thought to result from inhibition of serotonin and norepinephrine reuptake at the synaptic cleft. Animal studies have shown anticholinergic and antihistaminergic activity with doxepin. Blockade of the H1 receptor by doxepin likely plays a role in reducing wakefulness. Typically, therapeutic doses of antidepressants with anti-histaminergic properties, doxepin 5mg, doxepin as doxepin at antidepressant 5mg, amitriptyline, or desipramine, do not selectively block H1 receptors, doxepin 5mg, but act at cholinergic, serotonergic, adrenergic, histaminergic, and muscarinic receptors, which can cause 5mg effects.
Doxepin for insomnia
Pharmacokinetics When doxepin, 6 mg, was administered to healthy, 5mg patients, doxepin 5mg, time to maximum concentration Tmax was 3. Peak plasma concentration Cmax increased in a dose-related doxepin when doxepin was doxepin from 3 mg doxepin 6 mg. Therefore, to prevent a delay in onset 5mg action and to minimize the likelihood of daytime sedation, doxepin should not be 5mg within 3 hours of a meal.
If doxepin is coadministered with drugs zerit 20mg inhibit these isoenzymes, doxepin 5mg, such as fluoxetine and paroxetine, doxepin blood levels may increase.
Doxepin and Weight Gain
Doxepin does not seem to induce CYP isoenzymes. This medication is metabolized by demethylation and oxidation; the primary metabolite is nordoxepin N-desmethyldoxepinwhich later undergoes glucuronide conjugation. The half-life is 15 hours for doxepin and 31 hours for nordoxepin. Doxepin is excreted in 5mg primarily as glucuronide conjugate. Efficacy Doxepin reduced insomnia symptoms in 3 pilot 5mg at doses of 10, doxepin 5mg, 25, and 50 mg, doxepin in 2 phase III randomized, doxepin 5mg, double-blind, placebo-controlled clinical trials using doxepin, 3, and 6 mg Table 2.
All patients received all treatments, and each treatment was followed by 8 hours of polysomnography PSG evaluation in a sleep laboratory. Wake after doxepin onset WASOtotal sleep time TSTand sleep efficiency SE improved with all doxepin doses, and wake time during sleep WTDS —which was the primary study endpoint—decreased with 3 mg and 6 mg doses, but not with 1 mg or placebo.

5mg addition, doxepin 5mg, PSG indicators of early-morning awakenings terminal insomnia were reduced, as shown by an increase in SE during the final third of the night and the 7th and 8th hours of sleep 1, 3, and 6 mg doses and a reduction in wake time after sleep WTAS during the final third of the night 6 mg only.
The effects on sleep duration doxepin maintenance were more robust with 3 mg and 6 mg doses. Improved sleep onset was seen only with the 6 mg dose.
