Da Zeagra Tablet 4's belongs to the class of medications called ‘sex stimulants’ used in the treatment of premature ejaculation and erectile dysfunction in adult men. Premature ejaculation is when a man ejaculates (orgasms) more quickly with less sexual stimulation before the man or his partner would like. This could lead to problems in a sexual relationship. Erectile dysfunction is the inability to keep a hard and erect penis suitable for sexual activity. Da Zeagra Tablet 4's contains Dapoxetine and Sildenafil. Dapoxetine is a short-acting selective serotonin reuptake inhibitor (SSRI) that increases the serotonin levels in the brain, thereby increasing the time to ejaculate and improving the control over ejaculation. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor and works by relaxing the blood vessels. It can improve blood flow to the penis and helps to get an erection when sexually stimulated.
