Sildenafil Duration of Action in Men With Erectile Dysfunction


When taking an erectile dysfunction treatment, timing is crucial. You may have a specific time in mind for when you want to be erection-ready. Sildenafil has a window of four to six hours when it is at its peak potency. After that, it gradually degrades in your system, taking about three to five hours to completely go away.

Duration of action of sildenafil

A recent study sought to evaluate the duration of action of sildenafil in men with erectile dysfunction (ED). The study included 17 men with ED without an organic cause and administered 50 mg of sildenafil orally for six hours. RigiScan(R) monitoring devices were used to measure penile rigidity after administration. A significant decrease in penile rigidity was noted after 70 minutes of sildenafil administration.

The study also examined the efficacy of sildenafil on erectile function in men with ED. The researchers found that the medication was effective for a significant proportion of men with ED and improved self-assessed erectile function. In fact, sildenafil was effective up to 12 hours after administration.

How to take?

Sildenafil is most effective when taken as a single oral dose. Its rapid absorption and short half-life ensure an appropriate duration of effect and prevent drug accumulation in chronic once-daily use. However, the duration of action may vary from individual to individual. If sildenafil is taken for more than four hours daily, it may be beneficial to eat a meal prior to taking it.

The duration of action of sildenafil is dependent on the dose and duration of the erection. The dose of sildenafil must be adjusted to accommodate the age of the patient and the severity of the condition. The lower dose is generally reserved for special populations, such as the elderly, the sick, and those who are sensitive to side effects.

Duration of action of VIAGRA

Sildenafil’s duration of action is generally short, with peak plasma concentrations occurring in as little as 30 to 120 minutes. This is consistent with other clinical trials. Sildenafil is usually administered three times daily. Depending on the dosage, the duration of action may be longer or shorter.

In one study, sildenafil was administered to rats for 24 hours. Males were exposed to UK-103,320, whereas females were exposed to the unchanged drug. The dose-related exposure was much higher in females than in males. Although there was no significant mortality, females were more likely to lose body weight after treatment. This may be due to the fact that the drug induces enzymes.

Sildenafil is a cGMP-specific phosphodiesterase type 5 (PDE5) inhibitor. It inhibits PDE5 and increases cGMP in the corpus cavernosum, which results in relaxation of smooth muscles and increased blood flow to the penis. Sildenafil does not have this effect in the absence of sexual stimulation. It inhibits PDE7-PDE11 by a factor of 700, and is highly selective for PDE3 (which is involved in cardiac contractility).

Sildenafil has a half-life of three to four hours, so it is essential to take the medication at least one hour before sexual activity. It is also important to note that sildenafil has an adverse effect on the visual system and may impair the ability to hear. This could make the drug less effective for sexual activity.

Duration of action of Tadalafil

Duration of action is a critical factor when choosing a male erectile dysfunction (ED) medication. Unlike some other ED medications, Tadalafil has a long half-life and can be taken up to 36 hours before a sexual intercourse. While this may sound great for some men, it can have negative effects on a man’s health.

When taking tadalafil, it is vital to wait a few minutes for it to take effect. Generally, the medication takes up to 15 minutes to produce an erection, but for some men it can take two hours. If the drug is taken too early, it can cause a man to experience performance anxiety and lower his self-confidence. Ultimately, this can lead to the treatment failing.

Tadalafil is a selective phosphodiesterase type 5 (PDE5) inhibitor. It is similar to Vardenafil and Sildenafil and is used to treat male erectile dysfunction, pulmonary arterial hypertension, and benign prostatic hypertrophy. Tadalafil’s duration of action is longer than that of its two main competitors. In addition, it does not cause any blockages of the gastrointestinal tract, making it useful for patients who are not able to drink water regularly.

Other information

Tadalafil is generally well tolerated. It rarely causes orthostatic hypotension or increased blood pressure. However, it should not be taken with alpha-blockers or nitrates. It is important to inform your doctor if you are taking any other medications or have undergone significant medical changes.
