Dapoxetine, sold under the brand name Priligy among others, is a selective serotonin reuptake inhibitor (SSRI) used for the treatment of premature ejaculation (PE) in men ages 18 to 64 years old. [ 3 ] [ 4 ] [ 5 ] Dapoxetine works by inhibiting the serotonin transporter , increasing serotonin's action at the postsynaptic cleft, and as a ...
The field of pharmacotoxicology also involves the treatment and prevention of pharmaceutically induced side effects. Pharmacotoxicology can be separated into two different categories: pharmacodynamics (the effects of a drug on an organism), and pharmacokinetics (the effects of the organism on the drug).
This side effect has been particularly associated with serotonergic antidepressants like SSRIs and SNRIs, but may be less with atypical antidepressants like bupropion, agomelatine, and vortioxetine. [ 83 ] [ 85 ] [ 86 ] Higher doses of antidepressants seem to be more likely to produce emotional blunting than lower doses. [ 83 ]
Lemborexant is used in the treatment of insomnia in adults. [3]A major systematic review and network meta-analysis of medications for the treatment of insomnia published in 2022 found that lemborexant had an effect size (standardized mean difference (SMD)) against placebo for treatment of insomnia at 4 weeks of 0.36 (95% CI Tooltip confidence interval 0.08 to 0.63) and at 3 months of 0.41 (95% ...
Type A reactions are dosage (concentration) dependent. Usually, this kind of side effect is an extension of an ongoing treatment. Pharmacokinetics and pharmacodynamics are termed toxicokinetics and toxicodynamics in the field of ecotoxicology. Here, the focus is on toxic effects on a wide range of organisms.
Pharmacokinetics is the movement of the drug in the body, it is usually described as 'what the body does to the drug' the physico-chemical properties of a drug will affect the rate and extent of absorption, extent of distribution, metabolism and elimination.
Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...
Rates of sexual dysfunction in MDD patients treated with duloxetine versus escitalopram did not differ significantly at 4, 8, and 12 weeks of treatment, although the trend favored duloxetine (33.3% of duloxetine patients experienced sexual side effects compared to 43.6% of those receiving escitalopram and 25% of those receiving placebo).
