Product Detail

Introduction

Premature ejaculation (PE) is the most common male sexual dysfunction. hydrochloride,marketed as and Westoxetin, is a class of PE treatment drugs known as selective serotonin reuptake inhibitors (SSRI) , was the first drug originally approved for the on-demand treatment of men 18-64 years old with PE.

works by inhibiting the serotonin transporter, increasing serotonin's action at the post synaptic cleft, and as a result promoting ejaculatory delay. was initially developed as an antidepressant. However, unlike other SSRIs, is absorbed and eliminated rapidly in the body. Its fast acting property makes it suitable for the treatment of PE but not as an antidepressant.

Used for the treatment of premature ejaculation and erectile dysfunction. Over 98% of men taking this drug will naturally gain a improved erection quality with prolonged time and more frequencies.

Physical and chemical properties

White crystal powder with sweet taste and no odor, hygroscopic and soluble in water. It has a stable chemical property with the melting point at 175~177℃.

PE treatment

Premature ejaculation (PE) is a common problem worldwide and has significant impact not only on the sufferer but on the partner in terms of self-esteem, interpersonal distress and sexual satisfaction. Tricyclic antidepressants and clomipramine are the most widely used drugs for the treatment of premature ejaculation .

Randomized, double blind, placebo-controlled trials have confirmed the efficacy of for the treatment of PE. Different dosage has different impacts on different type of PE. 60 mg significantly improves the mean intravaginal ejaculation latency time (IELT) compared to that of 30 mg in men with lifelong PE, but there is no difference in men with acquired PE. , giving 1-3 hours before sexual episode, prolongs IELT, increases the sense of control and sexual satisfaction in men of 18 to 64 years of age with PE. Since PE is associated with personal distress, interrelationship difficulty, provides help for men with PE to overcome this condition. Because lack of specific approval treatment for PE in the US and some other countries, other SSRIs such as fluoxetine, paroxetine, sertraline, fluvoxamine, and citalopram have been used as off label drugs to treat PE. Waldinger's meta analysis shows that the use of these conventional antidepressants increasing IELT from two to ninefold above base line in comparison of three to eightfold when is used.

However, these SSRIs must be taken daily in order to achieve meaningful efficacy, and the long half-life increases the risk of the drug accumulation and as a consequence increased of adverse effects such as decreasing sexual libido and causing erectile dysfunction. , on the other hand, is a fast-acting SSRI. It is rapidly absorbed and eliminated from the body within a few hours. This favorable pharmacokinetics minimizes the risk of the drug's accumulation in the body, and therefore reducing side effects.

Mechanism of Actions

The mechanism through which affects premature ejaculation is still unclear. However, it is presumed that works by inhibiting serotonin transporter and subsequently increasing serotonin's action at pre and postsynaptic receptors. Human ejaculation is regulated by various areas in the central nervous system (CNS). The ejaculatory pathway originates from spinal reflex at the thoracolumbar and lumbosacral level of spinal cord activated by stimuli from male genital. These signals are relayed to the brain stem, which then is influenced by a number of nuclei in the brain such as medial preoptic and paraventricular nulcei. Clement's study performed on anaesthetized male rats showed that acute administration of inhibits ejaculatory expulsion reflex at supraspinal level by modulating activity of lateral paragigantocellular nucleus (LPGi) neurons. These effects cause an increase in pudendal motoneuron reflex discharge (PMRD) latency. However, it is unclear whether acts directly on LPGi or on the descending pathway in which LPGi located.

Development in Marketing internationally

Originally developed by Eli Lilly pharmaceutical company, was sold to Johnson & Johnson in 2003 and submitted as a New Drug Application to the Food and Drug Administration (FDA) for the treatment of PE in 2004. is sold in some European and Asian countries, and in Mexico. In the US, has been in phase III development since 2003. However, it was rejected by FDA last year.
