Design outcomes

Primary

MeasureTime frame
Change in Intravaginal Ejaculatory Latency Time - IELT: The mean IELT measured at week 4 after the start of treatment minus the mean IELT measured at baseline (before treatment). This change will be calculated for each of the three groups (dapoxetine, pregabalin, and placebo) and then compared with each other. Timepoint: The intravaginal ejaculatory latency time (IELT) will be measured at baseline (before the intervention) and during the 4 weeks following drug administration. Method of measurement: ELT is measured with a stopwatch by the patient himself during sexual intercourse. To determine the baseline IELT, the average time of 4 intercourses prior to treatment is calculated. To determine the post-treatment IELT, the average of the times measured during the 4-week treatment period is calculated.

Secondary

MeasureTime frame
Incidence of Adverse Events: Any untoward or undesirable medical occurrence in a participant that is temporally associated with the use of the investigational drug (Dapoxetine, Pregabalin, or placebo), regardless of whether it is definitively attributed to the drug. Timepoint: During the 4-week treatment period: The primary assessment will be conducted throughout the 4-week drug administration period. Patients will be instructed to report any adverse events to the researcher in the intervals between visits as well. Method of measurement: his variable is measured qualitatively using patient self-reporting combined with active inquiry by the researcher.
