medicine interactions
Voice
Possibility of interaction with monoamine oxidase inhibitor oxidase
In patients taking a selective serotonin reuptake inhibitor plus a monoamine oxidase inhibitor (MAOI), severe (sometimes fatal) reactions have been reported. These reactions include high fever, rigidity, myoclonus, spontaneous Neurological instability is accompanied by possible rapid fluctuations in vital signs and changes in mental state, including quarterly excitement and development of delirium and coma. Recently, a selective serotonin reuptake inhibitor was discontinued and a monoamine oxidase inhibitor was started These reactions have also been reported in patients treated with drugs, and some cases have features similar to neuroblocker malignant syndromes. 1. Possibility of interaction with monoamine oxidase inhibitors In patients taking a selective serotonin reuptake inhibitor and a monoamine oxidase inhibitor (MAOI) at the same time, there have been severe (sometimes fatal) reactions Reported that these reactions include high fever, rigidity, myoclonus, autonomic instability with possible rapid fluctuations in vital signs and changes in mental state, including extreme excitement and development of delirium and coma. These reactions have also been reported in patients who recently discontinued a selective serotonin reuptake inhibitor and started using a monoamine oxidase inhibitor. Some cases show features similar to neuromuscular blocker malignant syndrome. The combined use of selective serotonin reuptake inhibitors and monoamine oxidase inhibitors in animal models shows that these drugs may have a synergistic effect in raising blood pressure and inducing behavioral excitement. Therefore, this product cannot be combined with monoamine oxidase inhibitors. It cannot be used within 14 days of stopping the monoamine oxidase inhibitor. Similarly, monoamine oxidase inhibitors cannot be used within 7 days of stopping this product. (See taboo section)
2. Possibility of interaction with thioridazine
Thioridazine alone can prolong the QTc interval, which is accompanied by severe ventricular arrhythmia. Some drugs that can inhibit cytochrome P450 2D6 isoenzymes, such as Perigen, can inhibit the metabolism of thioridazine and lead to an increase in the concentration of thioridazine, which will increase the effect of prolonging the QTc interval.
This product cannot be combined with thioridazine, nor can it be used within 14 days of stopping thioridazine. Similarly, thioridazine cannot be used within 7 days of stopping this product. (See taboo section)
3. Medicines/herbal medicines with serotonin effect
Like other selective serotonin reuptake inhibitors, Pligen is compatible with drugs/herbals with serotonin effects (including monoamine oxidase inhibitors, L-tryptophan, triptan, tramadol, linezolid, The combined use of selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, lithium agents, and Hypericum perforatum extract (Hypericum) may cause serotonin effects. This product cannot be combined with other selective serotonin reuptake inhibitors, monoamine oxidase inhibitors or other drugs/herbal medicines with serotonin-related effects. Nor can it be used within 14 days after stopping these medicines/herbal medicines. Similarly, these medicines/herbal medicines cannot be taken within 7 days of stopping this product. (See taboo section)
Central nervous system active drugs
The combination of this product and CNS active drugs has not been systematically evaluated in patients with premature ejaculation. Therefore, if it is necessary to use this product with such drugs, the patients should be treated with caution.
The effect of combination drugs on dapoxetine
In vitro studies conducted in human liver, kidney and intestinal microsomes indicate that dapoxetine is mainly metabolized by cytochrome P450 2D6, cytochrome P450 3A4 and flavin-containing monooxygenase 1 (FMO1), so inhibitors of these enzymes may be Reduce the clearance rate of Dapoxetine.

Powerful cytochrome P450 3A4 inhibitor
Ketoconazole (200 mg twice a day for 7 days) can increase the CMAX and AUCINF of dapoxetine (60 mg single dose) by 35% and 99%, respectively. Taking into account the effects of free dapoxetine and desmethyl dapoxetine, if you take a strong CYP3A4 inhibitor, the active part (the sum of free dapoxetine and desmethyl dapoxetine) is the largest blood drug The concentration may be
Increased by about 25%, AUC may be doubled. Such an increase will be obvious in some patients, mainly including the lack of cytochrome CYP2D6 functional enzymes, namely cytochrome CYP2D6 weak metabolizers or combined use of strong cytochrome P2D6 inhibitors patient.
Therefore, this product is contraindicated in patients taking ketoconazole, itraconazole, ritonavir, saquinavir, telithromycin, nefazodone, nafenavir, atazanavir and other patients at the same time.
Moderate cytochrome P450 3A4 inhibitor
Taking moderate cytochrome P450 3A4 inhibitors at the same time, such as erythromycin, clarithromycin, fluconazole, amprenavir, furosanavir, aprepitant, verapamil and diltiazem, may also increase Exposure to dapoxetine and desmethyldapoxetine, especially those with weak metabolizers of cytochrome CYP2D6. Therefore, in combination with any of the above drugs, the maximum dose of this product is limited to 30mg, and it is recommended to use it with caution.
