Limitations of the study
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 dapoxetine 30mg tablet then analyzed using liquid chromatography-tandem mass spectrometry. The results showed that dapoxetine does not alter the pharmacokinetics of tadalafil or sildenafil. Taken one to three hours before sexual activity, it is rapidly absorbed in the body.
- Sildenafil can be combined with lifestyle changes for better results.
- Dapoxetine helps subjects gain better control during sexual activity.
- Use caution in hot weather as both drugs can cause dehydration.
- Patients should avoid grapefruit or high-fat foods around intake time.
- Sildenafil has been studied extensively for safety and efficacy.
- Dapoxetine's rapid onset makes it convenient for planned activity.
- These medications are not substitutes for safe sexual practices.
- Always follow the prescribed dosage and timing instructions.
Its maximum plasma concentration (Cmax) is reached one to two hours after oral administration.
- Sildenafil is used to treat erectile dysfunction in men.
- Dapoxetine is primarily prescribed for premature ejaculation.
- Sildenafil increases blood flow to the penis during arousal.
- Dapoxetine works by delaying serotonin reuptake, extending ejaculation time.

Dapoxetine hydrochloride is a Selective Serotonin Reuptake Inhibitor which is used in treating premature ejaculation. 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. 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.
| Condition | Explanation | Alternative Approach |
|---|---|---|
| Nitrate medications | Dangerous interaction leading to hypotension | Consult healthcare provider |
| Severe liver or kidney disease | Altered drug metabolism and excretion | Dose adjustment or avoidance |
| Hypersensitivity to ingredients | Allergic reactions possible | Discontinue use immediately |
| Heart conditions | Increased cardiovascular risks | Medical evaluation required |
A high-fat meal does reduce the Cmax slightly, but it is insignificant.
5.6 Adverse Reactions with the Concomitant Use of Ritonavir
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 of lateral paragigantocellular nucleus (LPGi) neurons. It can be taken with or without food.
| Medication Class | Interaction Effect | Recommendation |
|---|---|---|
| Nitrates | Severe hypotension | Avoid concomitant use |
| CYP3A4 inhibitors | Increased levels of sildenafil, dapoxetine | Dose reduction or avoid |
| Antihypertensives | Additive blood pressure lowering | Monitor blood pressure closely |
| Other PDE5 inhibitors | Increased risk of side effects | Use caution, dose adjustment |
Dapoxetine is absorbed and distributed rapidly in the body. The mean steady-state volume is 162 L.
8.4 Pediatric Use
[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, dapoxetine 60mg tablet price 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.
Product Sildenafil Citrate Tablets 100 mg
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. 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.
Therapeutic Categories
[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. 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. 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).
5.3 Effects on the Eye
[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. These pharmacokinetics are more favorable in that they might minimize drug accumulation in the body, habituation, and side effects. 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 not be used in men with moderate to severe hepatic impairment and in those receiving CYP3A4 inhibitors such as ketoconazole, ritonavir, and telithromycin.
Drugs you should not use with sildenafil
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. If a patient stops taking dapoxetine, he should wait for 7 days before receiving these drugs. The most common effects when taking dapoxetine are nausea, dizziness, dry mouth, headache, diarrhea, and insomnia.
Neurocognitive safety
[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). Dapoxetine is metabolized extensively in the liver and kidney by multiple enzymes such as CYP2D6, CYP3A4, and flavin monooxygenase 1.
- Consistent use of sildenafil can help maintain erectile function.
- Dapoxetine provides a pharmacological solution for PE.
- Both products should be stored in a cool, dry place away from children.
- Side effects may diminish with continued use or dose adjustment.
- Some patients may require alternative therapies if side effects occur.
- Clinical guidelines recommend consultation before combining treatments.
- Dapoxetine's short half-life minimizes residual effects.
- Patients should inform healthcare providers about all current medications.
The major product at the end of the metabolic pathway is circulating dapoxetine N-oxide, which is a weak SSRI and contributes no clinical effect.
