Understanding Premature Ejaculation Medications

global) PE—indicates PE that is limited to specific partner or situation, while the patient enjoys satisfactory intercourse in other contexts [5]. The National Health and Social Life Survey, a probability sample study of sexual behavior in men and women aged 18–59 years, reported a prevalence of 21% among men in the United States [6].

Lidocaine- or prilocaine-based sprays, creams, or gels, as well as eutectic (i.e., melts easily) mixtures, have shown promise [26,27]. Their application offers a rapid onset of effect, with relatively mild numbness. A typically mild adverse side effects profile and availability for on-demand usage are other advantages in this category. In 9 of 11 men with PE, prilocaine-lidocaine cream (EMLA [eutectic mixture of local anesthetics], Astra Pharmaceuticals, Wayne, PA, USA) was shown to markedly improve IELT without any reported adverse events [28]. In phase II testing, topical eutectic mixture for PE (TEMPE), when used as an aerosol 15 minutes before intercourse, resulted in a 3.8 minute increased in IELT, compared to 0.7 minutes for the placebo.

Clomipramine (Anafranil)

While this constituted a 2.4-fold improvement over placebo, the numbers were too small to establish a statistically significant difference [27]. The topical application of anesthetic creams has the disadvantage of requiring a somewhat messy application within a condom, and the entire shaft is anesthetized. Aerosol TEMPE formulation, on the other hand, requires a decreased time for prior application, and only the glans penis is anesthetized [27,29]. This aerosol formulation is undergoing phase III trials in the United States, but is not Food and Drug Administration (FDA) approved at the time of this writing. So far, there has been an agreement neither on the amount of medication nor on the timeframe for its application. Nathan [7] analyzed the findings of 22 general population sex surveys, and estimated the prevalence of PE to be 35%.

Most estimates from other general population prevalence studies fall between 22% and 38%, with ranges from 4% to 39% [8–10]. The wide variability in the reported ranges is mirrored in the variability and lack of standardized definitions for PE. A number of studies have raised the point that in spite of the high prevalence rates, PE is the disorder for which patients are least likely to seek professional assistance, raising the distinct possibility that the problem may be more prevalent than currently estimated [8,10]. More recently, the PE Prevalence and Attitudes (PEPA) internetbased survey of 12,133 men aged 18–70 in the United States, Germany, and Italy reported a prevalence of 22.7% [11]. It is noteworthy that only 9% of the men in this survey had consulted a physician, and more than 90% reported little or no improvement after they sought treatment, leading to a general lack of satisfaction with the results. It has also been suggested that the prevalence of PE may vary between racial groups; one recent survey of 1,320 men found that PE was more prevalently admitted among Hispanic men, highlighting the importance of further investigation of ethnic and cultural variances in PE worldwide [12].

• Dapoxetine is specifically designed for on-demand use in PE.
• Topical anesthetics require minimal use to avoid excessive numbness.
• SSRIs impact neurotransmitters involved in ejaculation control.
• Tramadol's side effects limit its routine use for PE.
• Non-drug approaches include psychological counseling and exercises.
• Pelvic strengthening exercises aid in delay of ejaculation.
• Partner education enhances understanding and support.
• Managing stress and anxiety can significantly improve PE.
• Some therapies combine medication with sex therapy sessions.
• Medical evaluation is essential before initiating treatment.
• Lifestyle factors like smoking can influence sexual performance.
• Patient adherence to treatment plans improves outcomes.

The recurrent emerging pattern appears to be that PE is a largely underdiagnosed condition. The etiology of PE has been traditionally divided between “psychogenic” and “biogenic” factors. Psychogenic causes include anxiety, an unpleasant introductory or early sexual experience, infrequent sexual intercourse, poor ejaculatory control techniques, and evolutionary as well as psychodynamic factors. Urologic causes, including chronic prostatitis, have also been implicated [14]. Early animal studies revealed that nonselective agonists of the 5-HT2C receptors delay ejaculation, but selective 5-HT2A agonists do not have a similar effect, and selective 5-HT1A agonists cause a shorter ejaculatory latency compared with 5-HT2C agonists [15,16].

hypothesized that PE may be secondary to relative hyposensitivity of the 5-HT2C and/or 5-HT1A hypersensitivity [17]. The effect of postsynaptic 5-HT receptor activation on delayed ejaculation was later confirmed by using different selective serotonin reuptake inhibitors (SSRIs) [18–22]. The possible influence of genetic causes was investigated in a survey of 1,196 men in Finland that suggested the presence of a familial or genetic influence in 28% of men [23]. Decreasing sensory perception in the penis has been the goal of most topical male enhancement pill agents aimed at treating PE. As a general rule, reliable controlled studies have been lacking in this area. Penile biothesiometry studies have shown that patients with PE have increased penile sensitivity as shown by consistently decreased vibratory threshold that is not age dependent [24,25].

How Do You Treat Premature Ejaculation?

General objections to all forms of topical therapy include complaints of significant penile hypoanesthesia and risk of transvaginal absorption with vaginal numbness, unless a condom is utilized [1]. Irritating topical reactions, both penile and vaginal, can occur, and systemic reactions are also possible [31]. Efforts to wash off the medication prior to intercourse may reduce the risk of these side effects, but also reduce the spontaneity of the coital experience [12,33]. SS-cream studies have shown relatively minor side effects. These include mild local burning and mild pain without systemic adverse effects or adverse effects on sexual function or partner.

Lifestyle changes

Based on the level of evidence ratings of the studies reviewed, treatment of PE with topical anesthetics received a grade A recommendation from an expert panel at the Second International Consultation on Sexual Medicine [1]. The search for an effective, oral agent to remedy PE has been hampered by the complexity, variability, and subjectivity of this condition as noted earlier. Nevertheless, trials of centrally acting agents date back to as early as 1943 [34]. Some of the earlier medical approaches to the problem involved the use of alpha amino benzoate as well as various alpha blockers. Phenoxybenzamine, as well as more selective alpha blockers, such as terazosin and alfuzosin, were among the first agents utilized. Lidocaine- or prilocaine-based sprays, creams, or gels, as well as eutectic (i.e., melts easily) mixtures, have shown promise [26,27]. Their application offers a rapid onset of effect, with relatively mild numbness.

Recommended times for application have ranged from hour pink pills for woman to 20 minutes prior to intercourse [29]. compared the application of EMLA cream 20, 30, and 45 minutes before intercourse, and found 20 minutes to be the optimum period before anticipated intercourse for topical application [30]. In a double-blinded, randomized, placebocontrolled study of 42 patients—lidocaineprilocaine vs. placebo—the IELT improved with treatment from 1.49 to 8.45 minutes with lidocaine-prilocaine, while use of the placebo only increased the IELT from 0.7 to 1.9 minutes [31]. The application of an EMLA cream preparation—either lidocaine (2.5%) or prilocaine (2.5%)—20 to 30 minutes prior to intercourse has met with success [1].

What are common premature ejaculation medications?

In a placebo-controlled trial in 84 patients, when EMLA topical cream alone was compared with sildenafil alone or in combination with EMLA application, topical EMLA alone proved efficacious and had equal effectiveness to topical EMLA plus sildenafil therapy [2]. Similarly, a double-blind, randomized, placebocontrolled phase III clinical study of 106 patients with lifelong PE was conducted in three medical centers to investigate the efficacy of penile application of SS-cream. This herbal mixture, made from the extracts of nine natural products, was applied hour prior to intercourse and provided a dose-dependent clinical efficacy in 80% of men using the cream, as compared to 15% in the placebo group. IELT increased to greater than 2 minutes. After treatment, the mean ejaculatory latency was prolonged to 2.45 +/– 0.29 minutes in the placebo group, and 10.92 +/– 0.95 minutes in the SS-cream group [32]. The topical application of anesthetic creams has the disadvantage of requiring a somewhat messy application within a condom, and the entire shaft is anesthetized.

Fluoxetine was next shown to be helpful in the intentional treatment of PE [41]. Subsequently, a placebo-controlled trial of paroxetine proved promising [42]. A double-blind, fixed-dose trial of randomly assigned 20- or 40-mg daily doses of paroxetine in 27 patients with primary PE showed a statistically significant improvement in ejaculation time with both doses, as compared to placebo. Because the increase in the IELT was relatively similar in both groups, the authors concluded that daily 20-mg paroxetine “may be considered as an adequate treatment for primary premature ejaculation,” but that a higher dose may further increase the ejaculatory latency [42]. Kim and Seo compared the efficacy and safety of 4 weeks each of fluoxetine, sertraline, clomipramine, and placebo in treating PE in 36 men.
