Understanding Premature Ejaculation Medications

Efficacy and tolerability of dapoxetine in the treatment of premature ejaculation.

• Dapoxetine is taken as needed, usually 1-3 hours before sex for rapid action.
• Topical anesthetics should be used sparingly to avoid numbness of partner.
• SSRIs may cause side effects like nausea, dizziness, or decreased libido.
• Tramadol carries potential for abuse and should only be used under medical supervision.

Medication Summary

In contrast, > 90% of physicians thought that PE caused only minor or no distress to their patients. Approximately 12% of men stated that they had consulted a physician for this condition, with 80% claiming to have initiated the conversation and 85% reporting little or no improvement from this medical interaction. Clearly, PE is a common and distressing condition for a sizeable segment of the male population. Patients and couples often seek expensive and ineffective off-label therapies. Education about PE, its prevalence, and beneficial therapies for both consumers and physicians is urgently needed.

Premature ejaculation has various timing definitions ranging from ejaculating within one minute of penetration to ejaculating prior to a man's partner achieving orgasm. Essentially, a man or a couple can suffer from rapid ejaculation if one or both is unhappy with how rapidly the man ejaculates. For some couples, RE can occur 30 seconds into vaginal penetration.

Topical anesthetic agents

Dapoxetine has previously demonstrated its efficacy in the treatment of PE in 2 identically designed, double-blind, randomized, placebo-controlled, 12-week phase III trials. [9] An open-label, long-term (1 year) on-demand study of dapoxetine efficacy was presented. [10] Of the 1774 men enrolled in the 3-month studies (placebo, dapoxetine 30 mg and 60 mg) all were provided with dapoxetine 60 mg to be taken as needed 1 to 3 hours before sexual intercourse. Patients were evaluated at 1, 2, 3, 6, and 9 months in this extension study. The final results showed the pink pill for women that the improvements in satisfaction with sexual intercourse, control of ejaculation, symptom severity, and benefit from the medication were maintained through the duration of the study.

Paroxetine (Paxil, Pexeva)

Further analysis of the data sets from different groups of researchers revealed that dapoxetine equally improved IELT in men with both acquired and lifelong PE. [11] Additionally, men with PE who had the lowest IELTs appeared to benefit most. Men with a baseline IELT < 30 seconds had a 6.8-fold increase; those with a baseline IELT > 30 seconds and < 1 minute had a 4.4-fold increase; and those with baseline IELT > 1 minute and ≤ 2 minutes had a 3.2-fold increase. Additional studies involving dapoxetine showed minimal food effects. [13] Mean maximal plasma concentrations of dapoxetine decreased slightly after a high-fat meal, from 443 ng/mL (fasted) to 398 ng/mL (fed), and were delayed by approximately 0.5 hours following a high-fat meal (1.3 hours fasted, 1.63 hours fed). For others, RE may extend out to five or ten minutes. As long as one of the partners is dissatisfied, RE is a problem.

Does Viagra help premature ejaculation?

None of the current off-label medications fulfill all these criteria. In a community-based practice study 32.7% (201/614) of men reported PE. [6] None of the men with self-declared PE in this study were currently seeking a treatment, but most (80%) reported that if they sought treatment for PE, their primary goal would be sexual satisfaction for both themselves and their partner. Eighty-one percent reported that a pill to prolong IELT would be their treatment of choice. Dapoxetine hydrochloride is the first oral compound developed specifically for the treatment of PE.

International Society of Sexual Medicine

In preclinical studies, dapoxetine was found to be a potent inhibitor of serotonin reuptake and is considered by authorities in the field to be a serotonin transporter inhibitor. In experimental animal studies, researchers from Paris, France, evaluated the emission and expulsion phases of ejaculation using p-chloroamphetamine-induced ejaculation in anesthetized rats. [7] Different doses of intravenous dapoxetine reduced both the emission and expulsion phases in a dose-dependent manner. Similar experiments in the same anesthetized-rat model were conducted to elucidate the drug's mechanism of action. These studies revealed that dapoxetine worked by increasing the pudendal motor neuron reflex latency period. A man doesn’t have much control over how quickly he ejaculates.

Pryor J, Althof S, Steidle, Miloslavsky, Kell S. Ejaculation is mostly an event of the autonomic nervous system, the part of our nervous system we can’t fully control. Heartbeat, digestion, sweating are all examples of neurologic processes our autonomic nervous system controls. Therefore, when a man gets a signal to ejaculate, the point of no return, he’s going to go. The most sensitive part of the penis is the area around the frenulum, the skin flap on the underside of the penis just below the urethral meatus (where he urinates). There is a spinal cord pathway that connects there and rapidly sends signals to the ejaculation center of the spinal cord. Serotonin, dopamine, prolactin, testosterone and oxytocin are all hormones that play a role in ejaculation.

This is a very troubling condition for men as it compromises their sexual satisfaction and inhibits them in relationships.

Some recent studies shed light on PE and RE but the exact causes are still not known.

Psychological: Classic literature on RE suggests it is a trained sexual response fostered by men secretively masturbating as adolescents and trained to finish quickly. This behavior was then reinforced with early partner encounters where young couples engage in clandestine sexual activity in parents’ basements or car back seats.

The bottom line

There was no effect of food on elimination of this agent, with < 5% of peak plasma concentration being present 24 hours after oral administration. Interestingly, the most frequent AE with dapoxetine is nausea, which was decreased after a high-fat meal (24% of fasted and 14% of fed subjects). Perhaps a complete steak dinner will be required with this medication for the patients who complain of nausea. The question of daily dosing and accumulation was reported in a study of 42 healthy males. [14] Dapoxetine was rapidly absorbed with mean maximal plasma concentrations achieved at 1.01 and 1.27 hours after single doses of dapoxetine 30 and 60 mg.

With repeated daily dosing, steady-state plasma concentrations were reached within 4 days, with modest accumulation (1.5-fold). Elimination of dapoxetine was rapid and biphasic, with initial and terminal half-lives of 1.4 and 20 hours. The authors concluded that the pharmacokinetic profile of dapoxetine is ideally suited to an on-demand oral therapy for PE. Even though PE is the most common male sexual dysfunction, it seems to be under-reported by patients and underestimated by physicians. There have been 2 large surveys conducted -- one that looked at the prevalence cenforce 200 uk and attitudes regarding PE among 11,543 men from the United States, Germany, and Italy, and another querying 271 physicians (primary care physicians, urologists, and psychiatrists) from the United States, Germany, Italy, and Mexico..[15] Seventy-two percent of men with self-reported PE claimed significant worry about their ability to last during intercourse, with 59% reporting frustration at climaxing too soon. There is no proof that this is a real thing, however, and physicians suggesting this as a cause of RE reinforces guilt associations with sexuality. Neurobiological: The neurotransmitter serotonin (5HT) plays a central role in the ejaculatory response. Low levels of serotonin in specific areas of the brain may lead premature ejaculation. Studies have shown that increases in serotonin levels can help delay ejaculation in some men.

• Dapoxetine has a rapid onset, typically within 1-3 hours.
• Topical anesthetics should be applied in small amounts to avoid overdose.
• SSRI side effects may include sleep disturbances or gastrointestinal upset.
• Tramadol can cause dizziness, dry mouth, and nausea as side effects.
• Behavioral techniques teach men to recognize early signs of ejaculation.
• Pelvic floor training can enhance ejaculatory control.
• Counseling sessions help address performance anxiety and stress.
• Medications should be used as prescribed to minimize risks.
• Some men respond better to combination therapies.
• Abstaining from excessive masturbation may help in some cases.
• Lifestyle changes and psychological support are important adjuncts.
• Any medication or supplement should be discussed with a healthcare professional.

This provides the rationale for treating RE with anti-depressants in the selective serotonin reuptake inhibitor (SSRI) class. Penile Sensitivity: The ejaculatory spinal cord pathway is located at the ventral tip of the corona (if you’re standing up and looking down at your penis, the ventral side is on the bottom.
