Tadalista 60 mg (containing Tadalafil) and Fildena (containing Sildenafil) are both PDE5 inhibitors commonly prescribed for the treatment of erectile dysfunction (ED). While they work in similar ways by increasing blood flow to the *****, there are some key differences in their active ingredients, duration of action, and side effects. Let's break down how Tadalista 60 compares to Fildena in several key areas: 1. Active Ingredient & Mechanism of Action: Tadalista 60 mg: Contains Tadalafil, which works by inhibiting the PDE5 enzyme, thus increasing the levels of cGMP (cyclic guanosine monophosphate) in the *****. This promotes smooth muscle relaxation and increased blood flow during ***** stimulation, helping to achieve and maintain an erection. Tadalafil has a longer half-life than Sildenafil, which means it stays in the body for a longer period. Fildena: Contains Sildenafil, which also inhibits PDE5 to increase blood flow to the ***** during ***** arousal. However, Sildenafil has a shorter half-life than Tadalafil, and its effects tend to wear off more quickly. 2. Duration of Action: Tadalista 60 mg: The effects of Tadalafil (Tadalista 60) can last up to 36 hours, which is significantly longer than Sildenafil. This extended duration has earned Tadalafil the nickname "the weekend pill", as it allows for spontaneous ***** activity over a longer period, making it convenient for men who don’t want to time their dose too precisely.
