Dapoxetine: Uses, Interactions, Mechanism of Action DrugBank Online

Using alcohol or tobacco with certain medicines may also cause interactions to occur. Using this medicine with any of the following medicines is usually not recommended, but may be required in some cases. Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

• Based on these results, doses of 30 mg and 60 mg were chosen for further investigation in phase III efficacy and safety studies.
• In a phase II proof-of-concept study conducted by PPD, dapoxetine demonstrated a statistically significant increase in ejaculatory latency when compared to placebo.
• Dapoxetine is a selective serotonin reuptake inhibitor currently undergoing trials through Alza (under license from GenuPro, a collaboration between Eli Lilly and PPD).
• Many medicines have side effects along with useful medicinal effects.
• Although this medicine is very effective for certain patients, it may also cause some unwanted reactions if taken the wrong way.

Pharmacokinetics and metabolism

To review evidence supporting the efficacy and safety of dapoxetine in the treatment of PE. The drug’s mechanism of action is thought to be related to inhibition of neuronal reuptake of serotonin and subsequent potentiation of serotonin activity. The central ejaculatory neural circuit comprises spinal and cerebral areas that form a highly interconnected network.

If the effect of 30 mg is insufficient and the side effects are acceptable, the dose may be increased to the maximum recommended dose of 60 mg. Using this medicine with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

Specially designed “climax control” condoms are available without a prescription. These condoms contain numbing agents such as benzocaine or lidocaine to delay ejaculation. By repeating as many times as needed, you can reach the point of entering your partner without ejaculating. After some practice, delaying ejaculation might become a habit that no longer requires the pause-squeeze technique.

Acute intravenous paroxetine appeared less effective than dapoxetine. However, the author is of the opinion that many men may prefer the convenience of ‘on-demand’ dosing of dapoxetine compared with daily dosing. Men who infrequently engage in sexual intercourse may prefer on-demand treatment, whilst men in established https://www.turismomarmolejo.com/2024/05/24/ghrp-2-10-mg-peptide-sciences-results-4/ relationships may prefer the convenience of daily medication. Well designed preference trials will provide additional detailed insight into the role of on-demand dosing.

The use of SSRIs to treat PE is based on the observation that delayed ejaculation and anorgasmia are common side effects of this class of drugs (41,63). SSRIs, either alone at low doses or in combination with psychosexual counseling are widely accepted as first line treatments for lifelong PE (14). Men with acquired PE generally receive targeted therapy aimed at resolving the underlying etiology of their PE, either with or without the addition of SSRIs (10). SSRIs act to block the axonal reuptake of serotonin from the synaptic cleft of central serotonergic neurons by 5-HT transporters, which desensitize the 5-HT1A and 5-HT1B receptors (64). The delay in ejaculation can occur within a few days; however, chronic administration for at least 2-3 weeks is necessary to maximize the drugs therapeutic effects (10).

Before having any kind of surgery, dental treatment, or emergency treatment, tell the medical doctor or dentist in charge that you are using this medicine or have used it within the past 10 days. Taking isocarboxazid together with medicines that are used during surgery, dental, or emergency treatments may increase the risk of serious side effects. Although this medicine is very effective for certain patients, it may also cause some unwanted reactions if taken the wrong way. It is very important to avoid certain foods, beverages, and medicines while you are using isocarboxazid. Your doctor may provide a list as a reminder of which products you should avoid. My last article gave insight on the non-medical methods of controlling premature ejaculation.

Treatment-emergent adverse events occurring in at least 2% of subjects in pooled phase III data [Buvat et al. 2009; Kaufman et al. 2009; McMahon et al. 2010; Pryor et al. 2006]. Dapoxetine is extensively metabolized in the liver by multiple isozymes to multiple metabolites, including desmethyldapoxetine, didesmethyldapoxetine and dapoxetine-n-oxide, which are eliminated primarily in the urine [Dresser et al. 2004; Modi et al. 2006]. Although didesmethyldapoxetine is equipotent to the parent dapoxetine, its substantially lower plasma concentration, compared with dapoxetine, limits its pharmacological activity and it exerts little clinical effect, except when dapoxetine is coadministered with cytochrome P450 3A4 (CYP3A4) or CYP2D6 inhibitors.
