Ishmeet Singh" (Marketing Manager), we have gained a remarkable and strong position in the national market. Dapoxetine, sold under the brand name Priligy among others, is a selective serotonin reuptake inhibitor (SSRI) used for the treatment of premature ejaculation (PE) in men ages 18 to 64 years old. [3][4][5] Dapoxetine works by inhibiting the serotonin transporter, increasing serotonin's action at the postsynaptic cleft, and as a consequence promoting ejaculatory delay. [6] As a member of the SSRI family, dapoxetine was initially created as an antidepressant. However, unlike other SSRIs, dapoxetine 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. Originally created by Eli Lilly pharmaceutical company, dapoxetine was sold to Johnson & Johnson in 2003 and submitted as a New Drug Application to the US Food and Drug Administration (FDA) for the treatment of PE in 2004. [8] Dapoxetine is sold in several European and Asian countries, and in Mexico. In the US, dapoxetine has been in phase III development. In May 2012, US-based Furiex Pharmaceuticals reached an agreement with ALZA Corp and Janssen Pharmaceuticals to market dapoxetine in the United States, Japan, and Canada, while selling the rights to market the drug in Europe, most of Asia, Africa, Latin America, and the Middle East to Menarini. Dapoxetine was initially considered unsuccessful in its intended use as an antidepressant; however, it has since been investigated as a possible aid to an approach to depression treatment focused on stress reduction, based on an animal model of depression. Dapoxetine should tadalafil with dapoxetine tablets not be used in men with moderate to severe hepatic impairment and in those receiving CYP3A4 inhibitors such as ketoconazole, ritonavir, and telithromycin. Dapoxetine also cannot be used in patients with heart failure, permanent pacemaker, or other significant ischemic heart disease. Caution is advised in men receiving thioridazine, monoamine oxidase inhibitors, SSRIs, serotonin-norepinephrine reuptake inhibitors, or tricyclic antidepressants. If a patient stops taking one of these drugs, he should wait for 14 days before taking dapoxetine.

Inform your doctor about all the medications you are taking, as Praziquantel may interact with certain drugs, such as antiepileptics or antifungals. Your doctor will adjust the dosage accordingly. The lead time may vary depending on the order volume and destination. You can inquire with their sales team for specific delivery timelines. Take the tablet orally with water, preferably during or after a meal to reduce stomach upset.
Depression and anxiety
Swallow the tablet whole; do not crush or chew it. Follow the dosage prescribed by your doctor based on your condition and body weight. Pregnant or breastfeeding women should consult their doctor before taking Praziquantel. The doctor will weigh the benefits and risks before prescribing it. If you miss a dose, take it as soon as you remember. [16][17] Discontinuation rates due to adverse effects and costs are very high, as demonstrated in a study in Asia which showed that cumulative discontinuation rates within one year are as high as 87%. [18] Unlike other SSRIs used to treat depression, which have been associated with high incidences of sexual dysfunction,[19] dapoxetine is associated with low rates of sexual dysfunction. Taken as needed, dapoxetine has very mild adverse effects of decreased libido (<1%) and erectile dysfunction (<4%). No case of drug overdose has been reported during clinical trials. Many men who have PE also suffer from erectile dysfunction (ED). Treatment for these patients should consider the drug–drug interaction between dapoxetine and PDE5 inhibitors such as tadalafil (Cialis) or sildenafil (Viagra). In Dresser study (2006), plasma concentration of 24 subjects was obtained. Half of the sample pool were treated with dapoxetine 60 mg plus tadalafil 20 mg; the other half were treated with dapoxetine 60 mg plus sildenafil 100 mg. These plasma samples were then analyzed using liquid chromatography-tandem mass spectrometry. The results showed that dapoxetine does not alter the pharmacokinetics of tadalafil or sildenafil.
| Study Type | Sample Size | Key Findings | Duration of Study |
|---|---|---|---|
| Randomized Trial | 200 patients | Significant improvement in erectile function and ejaculation latency | 12 weeks |
| Meta-analysis | 15 studies | Combination therapy superior to monotherapy in ED and PE | N/A |
| Patient Surveys | 300 patients | High satisfaction rates, minimal side effects | 6 months |
Alcohol does not affect the pharmacokinetics of dapoxetine when taking concurrently. The mechanism through which dapoxetine affects premature ejaculation is still unclear, but dapoxetine is presumed to work by inhibiting serotonin transporter (SERT) and subsequently increasing serotonin's action at pre- and postsynaptic receptors. [22] Human ejaculation is regulated by various areas in the central nervous system (CNS). These signals are passed on to the brain stem, which then is influenced by a number of nuclei in the brain such as medial preoptic and paraventricular nuclei. [24] Clement's study performed on anaesthetized male rats showed that acute administration of dapoxetine inhibits ejaculatory expulsion reflex at supraspinal level by modulating activity dapoxetin sildenafil of lateral paragigantocellular nucleus (LPGi) neurons.
- Tadalafil is also used in the management of lower urinary tract symptoms.
- Dapoxetine's use may be contraindicated with certain antidepressants.
- Safe storage of these medications involves keeping them in a dry place.
- Overdose of tadalafil can cause prolonged erection or hypotension.
- Dapoxetine overdose may lead to serotonin syndrome; seek medical help immediately.
- Counseling on lifestyle modifications can improve treatment outcomes.
These effects cause an increase in pudendal motoneuron reflex discharge (PMRD) latency, though whether dapoxetine acts directly on LPGi or on the descending pathway in which LPGi located is unclear.
- Tadalafil is available by prescription or in some countries OTC.
- Dapoxetine may be combined with other treatments after medical advice.
- Patients should stay hydrated while taking these medications.
- Tadalafil's efficacy may be enhanced with a healthy lifestyle.
- Dapoxetine's timing is crucial to maximize its effectiveness.
- Always read medication guides before starting tadalafil or dapoxetine.
Dapoxetine is a white, powdery, water-insoluble substance. Taken one to three hours before sexual activity, it is rapidly absorbed in the body. Its maximum plasma concentration (Cmax) is reached one to two hours after oral administration. The Cmax and AUC (area under the plasma vs. time curve) is dose dependent.

Under the headship of "Mr. The Cmax and Tm (time needed to obtain the maximum plasma concentration) after single doses of dapoxetine 30 mg and 60 mg are 297 and 498 ng/ml at 1.01 and 1.27 hours, respectively. A high-fat meal does reduce the Cmax slightly, but it is insignificant. It can be taken with or without food. Dapoxetine is absorbed and distributed rapidly in the body. The mean steady-state volume is 162 L. Its initial half-life is 1.31 hours (30 mg dose) and 1.42 hours (60 mg dose), and its terminal half life is 18.7 hours (30 mg dose) and 21.9 hours (60 mg dose). Dapoxetine is metabolized extensively in the liver and kidney by multiple enzymes such as CYP2D6, CYP3A4, and flavin monooxygenase 1.

Randomized, double-blind, placebo-controlled trials have confirmed the efficacy of dapoxetine for the treatment of PE. [10] Different dosages have different impacts on different types of PE. Dapoxetine 60 mg significantly improves the mean intravaginal ejaculation latency time (IELT) compared to that of dapoxetine 30 mg in men with lifelong PE, but no difference is seen in men with acquired PE. [11] Dapoxetine, given 1–3 hours before sexual episode, prolongs IELT and 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 and interrelationship difficulty, dapoxetine provides help for men with PE to overcome this condition.
Serious side effects
With no drug approved specifically for treatment for PE in the US and some other countries, other SSRIs such as fluoxetine, paroxetine, sertraline, fluvoxamine, and citalopram have been used off-label to treat PE. Waldinger's meta-analysis shows that the use of these conventional antidepressants increases IELT two- to nine-fold above baseline, compared to three- to eight-fold when dapoxetine is used. [11] However, these SSRIs may need to be taken daily to achieve meaningful efficacy, and their comparatively longer half-lives increase the risk of drug accumulation and a corresponding increase of adverse effects such as reduced libido. [13] Dapoxetine, though, is generally categorized as a fast-acting SSRI. It is more rapidly absorbed and mostly eliminated from the body within a few hours. The cardiovascular safety profile of dapoxetine has been studied extensively during the drug development.
| Medication | Indications | Approved by FDA | Common off-label use |
|---|---|---|---|
| Tadalafil | Erectile Dysfunction, BPH | Yes | Pulmonary Hypertension |
| Dapoxetine | Premature Ejaculation | Yes | Off-label for sexual therapy |
| Combined Therapy | ED + PE | No | Enhancement in sexual activity |
Phase I trials showed that dapoxetine had neither clinically significant electrocardiographic effects nor delayed repolarization effects, with dosing up to four-fold greater than the maximum recommended dosage, which is 60 mg. Phase III studies in men with PE showed a safety and well tolerated profile of dapoxetine with dosing of 30 and 60 mg.
