Dapoxetine is a modern drug that is used to eliminate problems in the genital area of men. The agent is a serotonin uptake inhibitor, which ensures the normalization of ejaculation in men from 18 to old age.
The ejaculation process is mainly regulated by the sympathetic nervous system. Postganglionic sympathetic nerve fibers innervate the seminal vesicles, the vas deferens, the prostate gland, the muscles of the urethra and the neck of the bladder, causing their coordinated contractions, leading to ejaculation. Dapoxetine inhibits ejaculation, increasing the latency period and decreasing the duration of reflex impulses of motor neurons of the perineal ganglia.
The stimulus that triggers ejaculation is generated in the spinal reflex center, which is controlled through the brain stem by several nuclei of the brain, including the preoptic and paraventricular ones.
The active substance of the drug delays ejaculation by blocking receptors in the male cerebral cortex. The effect is manifested from the first dose and lasts for 3-4 hours, and increases depending on the concentration of the drug in the body. The required effect is achieved within 30 minutes after administration. The action of the drug is selective, aimed at curbing ejaculation and the absorption of serotonin.
After a course of treatment with Dapoxetine in men, the general condition of the body and the reproductive system improves, including the normalization of the psycho-emotional state, mood and behavior.
Dapoxetine is rapidly absorbed when taken orally. The maximum plasma content is reached in blood plasma 1-2 hours after the drug is consumed. The bioavailability of the drug is 42%. The drug can be taken with or without food. Plasma protein binding is about 99%.
Dapoxetine metabolites are excreted mainly in the urine as conjugates. Dapoxetine is rapidly excreted, as evidenced by its low plasma content 24 hours after ingestion.
