Managing premature ejaculation

A sudden reduction or cessation of long-term treatment with an SSRI can lead to ‘SSRI discontinuation syndrome’, a group of physical and psychological symptoms including nausea, vomiting, dizziness, headache, ataxia, drowsiness, excitement, anxiety, and insomnia.

These symptoms begin 1–3 days after drug cessation and typically continue for >1 week. These side-effects were reversible with SSRI re-introduction [Citation40].

As it is not entirely clear why the intervention works in the first place, it is difficult to identify why the treatment gains were lost over time. Decrease in motivation, additional sexual problems occurring in the relationship, and changes in attraction between partners, could all play a role in the loss of gained ejaculatory control. Although, squeeze and start/stop techniques, have been the mainstay of PE management for many years, evidence of their short-term efficacy and long-term benefit is lacking [Citation20]. All TCAs have a three-ring nucleus in their molecular structures [Citation21]. TCAs, and their derivatives, have been a cornerstone in medical treatment of depression.

Tramadol (Ultram, Rybix ODT, ConZip, Ryzolt)

They are very effective, but, their use is often associated with a variety of unpleasant and sometimes dangerous side-effects [Citation22] () [29,74,75,80,83,164–174]. Unwanted effects of TCAs arise through interactions with several different neurotransmitter systems. Clomipramine is a TCA that is indicated for the treatment of major depressive episodes, secondary depression, panic disorder with agoraphobia, generalised anxiety disorder, and obsessive–compulsive disorder (OCD) [Citation23]. Low doses of clomipramine have been suggested to be effective for the treatment of PE [Citation24]. The mechanism by which clomipramine delays ejaculation is unclear. An SSRI overdose or interaction with other drugs, can enhance serotonin activity in the CNS to the point of causing the ‘serotonin syndrome’, a group of serious, persistent symptoms including myoclonus, hyperreflexia, vardenafil cost sweating, shivering, discoordination, and mental status changes [Citation41].

It has largely (albeit not completely) substituted older and less safe drugs such as TCAs. Fluoxetine is a serotonin-specific antidepressant approved in 1987 by the FDA for treatment of depression [Citation42]. It is also a treatment option for patients with Alzheimer’s disease who have severe obsessive–compulsive symptoms [Citation43] and for patients with intention myoclonus [Citation44].

MeSH terms

They were especially indicated in cases of failed or rejection of psychological treatment, and when partners were unwilling to cooperate in treatment. The SSRIs are widely used because of their safety, tolerability and demonstrated efficacy across a broad range of clinical conditions [Citation11]. The ability of SSRIs to delay ejaculation was first coincidentally discovered as a result of use of these drugs in the treatment of depression in men in the 1970s [Citation30]. Antidepressants either elevate serotonin levels leading to inhibition of genital reflexes, or decrease dopamine with the same results [Citation31]. All SSRIs inhibit reuptake of serotonin into presynaptic serotonergic neurones, an action that increases the availability of serotonin at the synapse and ultimately, enhances serotonergic function in the central nervous system (CNS).

More Information

This mechanism of action depends on the binding of the drug to serotonin transporter protein [Citation32]. It has also been suggested that the efficacy of SSRIs in inhibiting PE, is probably due to increase synaptic 5-HT concentrations via blockade of the 5-HT transporter and activation of the 5-HT 2 C receptor, which then decreases the function of the 5-HT 1A receptor or restores the balance between the two receptor functions (5-HT 1A and 5-HT 2 C) [Citation33,Citation34]. The 5-HT transporter blockade induced by acute administration of all current SSRIs leads to higher serotonin levels in the synapse and in the space around the cells [Citation35]. Increasing serotonin levels activates 5-HT1A auto-receptors, resulting in less serotonin being released into the synaptic cleft within minutes [Citation36]. A higher serotonin concentration increases activation of presynaptic 5-HT1B auto-receptors, which alone can reduce the release of serotonin. Fluoxetine is more selective and more potent in retarding ejaculation as compared to TCAs [Citation45]. At a dose of 20 mg daily for 1 week followed by 40 mg daily for ~4 weeks, fluoxetine successfully improved PE in a double-blind placebo controlled study of 17 patients [Citation46].

Another study revealed that a significant decrease in self-reported ‘poor’ ejaculatory control, high personal distress and high partner distress were noted in men receiving 20 mg fluoxetine for 12 months [Citation47]. The rationale with which fluoxetine is thought to exhibit its beneficial effects is through increasing the penile sensory threshold, without changing the amplitudes and latencies of sacral evoked response and cortical somatosensory evoked potentials [Citation48]. A study compared 90 mg once weekly dose with 20 mg daily doses fluoxetine on 80 patients with PE [Citation49]. After a 4-month treatment period, the authors reported significant prolongation in the IELT, together with improved International Index of Erectile Function (IIEF) results and partner sexual satisfaction in both groups.

What is Premature Ejaculation?

Decreased reuptake of serotonin (or 5-hydroxytryptamine [5-HT]) has been suggested as a mechanism by which several antidepressants including clomipramine delay ejaculation. Clomipramine may increase the sensory threshold for the stimuli in the genital area [Citation25]. Administration of 25 mg clomipramine orally 4 h before planned sexual intercourse was effective in the treatment of patients with PE [Citation26,Citation27]. However, the drug may cause mild yet annoying non-sexual side-effects such as sleepiness and yawning on the day of coitus, and significant nausea the day after. On-demand use of 15 mg clomipramine orally 4 h before sexual intercourse for 4 weeks was safe and effective in prolonging IELT in the treatment of patients with PE [Citation28].

What to expect from your doctor

The antihypertensive effect of propranolol and clonidine may be blocked by clomipramine. Clomipramine with α-methyldopa may men enhancement pills cause behavioural agitation. The plasma levels of clomipramine and antipsychotics are increased by their co-administration. The sedation effect of clomipramine and opioids, alcohol and hypnotics are increased by their co-administration []. The SSRIs have emerged as an effective treatment for patients with PE whether or not these patients suffer from depression [Citation29]. There were no significant differences between both treatment methods in terms of efficacy and reported side-effects.

Medication Summary

Given this background, on-demand SSRI treatment would not be expected to result in acute stimulation of 5-HT postsynaptic receptors. Consequently, one would expect minimal increase in synaptic serotonin levels and, thus, little or no synaptic stimulation of 5-HT receptors. Little or no activation of postsynaptic 5-HT receptors should then result in vigora 200 mg no clinically relevant delay of ejaculation [Citation37]. In contrast to their acute administration, chronic use of currently available SSRIs causes some physiological changes that delay ejaculation. Ongoing blockade of 5-HT receptors that mediate serotonin reuptake results in a persistent increase in serotonin levels in the synapse and in the space around the cells ().

Limitations associated with of SSRIs

As opposed to the acute administration of SSRIs, this ongoing blockage leads to desensitisation of the 5-HT1A auto-receptors in a few weeks; and possibly of the 5-HT1B auto-receptors [Citation38]. The net effect of the chronic administration of SSRIs is an increase in the serotonin released into the synapse and enhanced serotonin neurotransmission, thus resulting in a stronger activation of the 5-HT postsynaptic receptors compared with that observed in acute SSRI administration [Citation38]. These data predict that daily treatment of SSRI will stimulate the 5-HT postsynaptic receptors, leading to a clinically relevant ejaculation delay after 1–2 weeks of continuous intake [Citation37]. While serotonergic drugs are extensively used for the treatment of PE, there are limitations associated with their use. Some of these limitations include unwanted sexual side-effects such as decreased sexual desire and ED [Citation39]. The co-administration of fluoxetine and PDE5 inhibitors appears to have a potentiating effect on sexual satisfaction. The combination of fluoxetine (20 mg fluoxetine daily for 4 weeks followed by 20 mg on-demand 2–3 h before planned sexual activity for 4 months) with sildenafil (50 mg 1 h before sexual activity for 4 months) resulted in significantly better IELT and intercourse satisfaction compared with fluoxetine alone in patients with PE [Citation50]. Similarly, administration of 90 mg fluoxetine once per week plus 20 mg tadalafil within 36-h before planned sexual intercourse for 12 weeks in patients with lifelong PE resulted in significantly longer IELT compared with fluoxetine only or tadalafil only treatment [Citation51]. Citalopram is a potent specific inhibitor of neuronal serotonin reuptake [Citation52] that is indicated for the treatment of depression, anxiety, panic disorder, OCD, premenstrual dysphoria, alcohol dependence, and behavioural disturbances of dementia [Citation53].

The daily administration of 20 mg citalopram in patients with PE resulted in significant increase in IELT, improved overall patient sexual satisfaction, and decreased performance anxiety [Citation54,Citation55]. Citalopram was compared to SSRIs in several studies. A randomised controlled trial (RCT) compared the efficacy of citalopram 20 mg to sertraline 50 mg for a treatment period of 8 weeks in patients with PE. The authors reported a statistically significant increase in the results of the IPE questionnaire in both the citalopram and sertraline groups, without a significant difference in efficacy between the two treatments.
