Daxetin®

Dapoxetine

Prescribing Details



Description

Daxetin® is a preparation of Dapoxetine Hydrochloride which is a selective serotonin reuptake inhibitor (SSRI}. The mechanism of action of Dapoxetine in premature ejaculation is presumed to be linked to the inhibition of neuronal reuptake of serotonin and the subsequent potentiation of the neurotransmitter's action at pre and post synaptic receptors.


Uses

No Data


Indications

Daxetin® is indicated for the treatment of -

       Premature ejaculation
       Personal distress or interpersonal difficulty as a consequence of premature ejaculation
       Poor control over ejaculation


Dosage and administration

Adult men (18 to 64 years of age)
The recommended starting dose of Daxetin® for all patients is 30 mg, taken as needed approximately 1 to 3 hours prior to sexual activity. 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. The maximum recommended dosing frequency is one dose every 24 hours.


Elderly (age 65 years and over)
Safety and efficacy of Dapoxetine have not been established in patients age 65 years and over as limited data are available in this population.


Children and adolescents
Dapoxetine is not recommended for patients under 18 years of age


Patients with renal impairment
No dose adjustment is required but caution is advised in patients with mild or moderate renal impairment. Dapoxetine is not recommended for use in patients with severe renal impairment.


Patients with hepatic impairment
No dose adjustment is required in patients with mild hepatic impairment. Dapoxetine is contraindicated in patients with moderate and severe hepatic impairment.


Use in pregnancy & lactation

Pregnancy
Dapoxetine is pregnancy category C. Dapoxetine is not indicated for use by women. There are no adequate and well-controlled studies of Dapoxetine in pregnant women.


Lactation
Dapoxetine is not indicated for use by women. It is not known if either Dapoxetine or its metabolites are excreted in human breast milk.


Geriatric use
No Data

Precautions

General
Dapoxetine is only indicated in men with premature ejaculation. Safety has not been established and there are no data on the ejaculation-delaying effects in men without premature ejaculation.
Use with recreational drugs
Patients should be advised not to use Dapoxetine in combination with recreational drugs with serotonergic activity such as ketamine, methylenedioxymethamphetamine (MOMA) and lysergic acid diethylamide (LSD) because these may lead to potentially serious reactions if combined with Dapoxetine.


Syncope
The occurrence of syncope and possibly prodromal symptoms appears dose dependent as demonstrated by higher incidence among patients treated with doses higher than 60 mg, the recommended maximum daily dose.


Orthostatic hypotension
An orthostatic test should be performed before initiating therapy. In case of a history of documented or suspected orthostatic reaction, treatment with Dapoxetine should be avoided.

Warning
Combining alcohol with Dapoxetine may increase alcohol related neurocognitive effects and may also enhance neurocardiogenic adverse events such as syncope, thereby increasing the risk of accidental injury; therefore, patients should be advised to avoid alcohol while taking Dapoxetine.


Side effects
The most common reported side effects are loss of consciousness, orthstatic hypotension, headache, dizziness, nausea, diarrhoea, insomnia and fatigue.

Contraindications

Dapoxetine is contraindicated in patients with known hypersensitivity to Dapoxetine or to any of the excipients. It is also contraindicated in patients with heart failure, conduction abnormalities (second or third degree AV block or sick sinus syndrome) not treated with a permanent pacemaker, significant ischemic heart disease or significant valvular disease.


Drug interactions

Dapoxetine should not be used in combination or concomitantly with CYP3A4 inhibitors such as ketoconazole, itraconazole, ritonavir, saquinavir, telithromycin, nefazodone, nelfinavir, atazanavir, etc. It may also interact with SSRls, MAO ls, thioridazine, serotonin-norepinephrine reuptake inhibitors (SNRls}, tricyclic antidepressants (TCAs} and other serotonergic medicinal/herbal products.


Overdose
There were no unexpected events of overdose is reported with daily doses up to 240 mg (two 120 mg doses given 3 hours apart). In general, symptoms of overdose with SSRls include serotonin-mediated adverse reactions such as somnolence, gastrointestinal disturbances such as nausea and vomiting, tachycardia, tremor, agitation and dizziness. In cases of overdose, standard supportive measures should be adopted as required. Due to high protein binding and large volume of distribution of Dapoxetine, forced diuresis, dialysis, hemoperfusion and exchange transfusion are unlikely to be of benefit. No specific antidotes for Dapoxetine are known.
