Priligy (dapoxetine) is a potent, selective and fast-acting serotonin reuptake inhibitor. It is also responsible for inhibiting the reuptake of norepinephrine and dopamine. Researchers of this organic chemical compound assume that the action of dapoxetine is based on the inhibition of neuronal reuptake of serotonin, with subsequent enhancement of its action on the receptors of the sympathetic nervous system. It is the sympathetic nervous system that is responsible for male ejaculation. The highest concentration of Priligy in plasma is achieved two hours after dosing.
Pharmacological modulation of ejaculation is a novel concept, radically going beyond the psychosexual model of PE etiopathogenesis. The introduction of serotonin reuptake inhibitors (SSRIs) has revolutionized the approach to the treatment of this disorder. Lots of research concerning the EP were designed incorrectly or errors were made methodological, which makes them not reliable enough.
In a meta-analysis of studies on all drugs used in PE only 14.4% were found to be sufficiently confirmed effectiveness in reliable studies, and dapoxetine was by far the most effective medication. Unfortunately, drug treatment also has limited effectiveness: after its termination, the disorder frequently recurs.
Some authors believe that medications should be taken for the whole period of sexual activity. Currently, the best results are achieved when taking medications for a limited period (60 days) in combination with a couple of sexual therapy; the man gains control over his ejaculation and strengthens himself in overcoming PE.
The mechanism of action
Priligy is the sole medication authorized for the management of PE in males between 18-64 years of age. It belongs to the group of fast-acting and short-lived selective serotonin reuptake inhibitors (SSRIs). Dapoxetine works by blocking the reuptake of serotonin at synapses and stimulating dopaminergic and noradrenergic transmission. This drug is typically used as an “on-demand” medication, 1-3 hours before sexual activity, once per day. It is quickly absorbed in the gastrointestinal tract and attains its maximum plasma concentration approximately 1 hour after administration. The drug is rapidly excreted, so it does not accumulate in the body.
The pharmacokinetics of the drug depends on the dose, however, it does not depend on the consumption of food and alcohol. Priligy is metabolized in the liver too, inter alia, desmethyl dapoxetine and dimethyl dapoxetine. The metabolites are eliminated by the kidneys. It is not recommended for use in patients with liver and kidney damage, as well as in patients taking drugs that affect cytochrome P450 (e.g. ketoconazole, ritonavir) and taking other serotonin reuptake inhibitors.
Caution should be exercised in patients with diseases of the cardiovascular system. From the point of view of clinical practice, it is also important that no interactions with phosphodiesterase 5 inhibitors were observed. The above pharmacological features distinguish Priligy from other selective serotonin reuptake inhibitors.
Indications for use
Priligy is a drug dedicated to men who struggle with premature ejaculation.
The indications for the use of Priligy are:
- premature ejaculation in men aged 18 to 64;
- the intravaginal ejaculation delay time is less than two minutes;
- chronic or recurrent ejaculation with minimal sexual stimulation;
- personal and interpersonal anxiety resulting from premature ejaculation;
- poor control or complete lack of control over ejaculation;
- premature ejaculation in sexual contact within the last six months.
Priligy has proven to be an effective treatment option for premature ejaculation; however, its usage may not be recommended for all men facing this issue.
Contraindications to the use of Priligy are:
- hypersensitivity to any of the ingredients of the preparation;
- moderate or severe liver disorders;
- mania, hypomania, severe depression, or bipolar disorder;
- heart problems, such as heart failure, atrioventricular block, coronary heart disease, valvular disease;
- use of other serotonergic preparations.
Priligy can be taken with or without food. Initially, the recommended dose is 30 mg, to be taken three hours before the intended sexual activity. The dosage may be increased to 60 mg based on the medication’s effectiveness. However, it is important to note that Priligy should not be taken every day on a continuous basis. Once at least 6 doses have been taken, the benefits of continuing to use the medication should be weighed against the potential risks associated with its frequent usage.
Priligy, like any other drug, may cause various side effects.
They are divided according to the frequency of occurrence:
- dizziness, headaches, and nausea;
- the use of the drug may cause anxiety, agitation, anxiety, insomnia, decreased libido, sleepiness, blurred vision, tinnitus, diarrhea, vomiting, excessive sweating, erectile dysfunction, or irritability;
- depressive mood, euphoria, nightmares, grinding of the teeth, fainting, taste disturbance, increased heart rate, increased blood pressure may uncommonly occur.
Before use, read the leaflet, which contains indications, contraindications, data on side effects and dosage as well as information on the use of the medicinal product, or consult your doctor or pharmacist, as each drug used improperly is a threat to your life or health.
Priligy has been proven effective in treating premature ejaculation, with studies demonstrating its high safety profile and tolerability. On average, the drug increases the duration of intercourse by 3-4 minutes. Notably, dapoxetine can be used as an “on-demand” medication for emergency situations. The drug’s minimal side effects and high effectiveness make it a superior option compared to other PE treatments, which may be less effective or have a higher incidence of adverse effects.
Psychotherapy can be an alternative as well as a method supporting the treatment of PE. The choice of therapy should be discussed with the patient and, if possible, with the partner. The therapy of sexual dysfunctions is currently an increasingly common problem not only in the offices of psychologists, psychiatrists or sexologists, but also a problem faced by internists and cardiologists in their daily medical practice. To sum up, it should be emphasized that the treatment of PE with dapoxetine is possible and should be undertaken by doctors of various specialties, who treat patients with this problem.
