Extra Super Zhewitra contains two active ingredients: vardenafil (for erectile dysfunction) and dapoxetine (for premature ejaculation). While specific studies on Extra Super Zhewitra as a combination product are limited, there is significant research on each active ingredient individually that supports their effectiveness in treating these conditions: Vardenafil for Erectile Dysfunction: Multiple studies show that vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor, effectively improves erectile function by increasing blood flow to the penis. Studies have demonstrated that vardenafil helps men with erectile dysfunction achieve and maintain erections sufficient for sexual activity, with a relatively quick onset and fewer dietary restrictions compared to some other ED medications. Extra Super Zhewitra for Premature Ejaculation: Dapoxetine is a selective serotonin reuptake inhibitor (SSRI) specifically designed for on-demand treatment of premature ejaculation. Studies have shown that dapoxetine can significantly delay ejaculation time, helping men gain more control and improve satisfaction in sexual performance. Clinical trials have found dapoxetine effective and generally safe for men with moderate to severe premature ejaculation. Combination Use: While there may not be extensive studies on Extra Super Zhewitra specifically, using a combination of PDE5 inhibitors and SSRIs for managing both erectile dysfunction and premature ejaculation has been an area of interest in medical research. The combination addresses both erection quality and ejaculation control, providing a comprehensive approach for men with both conditions. For men who experience both ED and premature ejaculation, Extra Super Zhewitra offers a convenient, dual-action treatment. However, it’s essential to consult a healthcare provider to determine if this combination is suitable for individual health needs and to ensure safe usage.
