Vidalista contains the active ingredient Tadalafil, which is FDA-approved for treating Erectile Dysfunction (ED) in men. Tadalafil belongs to the Phosphodiesterase Type-5 (PDE-5) inhibitor class that widens the blood vessels in the penis to promote an increased blood flow for strong erections. Apart from this, Tadalafil is also approved to treat Pulmonary Arterial Hypertension (PAH) and Benign Prostatic Hyperplasia (BPH) under different brand names.
Tadalafil is widely popular for its 36-hour effectiveness window. This enables men to gain and maintain an erection for the time required for intimacy. However, various factors, such as age and health conditions, can influence the duration of action.
In this article, we will discuss how long does Vidalista last and what factors can significantly influence its duration. You’ll also learn how Tadalafil compares with other popular ED medications, as well as the important precautions to consider before taking it.
How long does Vidalista last in the body?
Vidalista can last for up to 36 hours, when taken as an as-needed dose for ED, making it one of the longest-acting ED medicines available to date. This extended window is why it’s widely referred to as the weekend pill. It is important to note that Tadalafil can’t cause an erection in the absence of sexual stimulation. Key points linked to Tadalafil’s duration are:
- Onset of action: After oral administration, it generally takes 30-60 minutes to show its effects under sexual arousal. Research indicates that after taking Tadalafil 20 mg, some men experienced an onset of action at 16 minutes.
- Effectiveness timeline: This ED tablet remains active for 36 hours to offer potential benefits, such as strong erections, improved sexual satisfaction, an increase in confidence, and better performance.
- Half-life: Half-life is the time required by a medication to decrease 50% of its initial amount in the body. The weekend pill has a long half-life of 17.5 hours.
- Not a sustained erection: The 36-hour effectiveness window does not mean a continuous erection throughout this period. Instead, it indicates that whenever sexually stimulated, men can gain a firm erection during this window.
