There are several treatments available for erectile dysfunction, and each have their own unique set of advantages.

Cialis is a popular ED drug, and is particularly noted for its lengthy 17.5 hour half-life and subsequent duration of function; which is up to 36 hours.

Duration of Activity

This characteristic has earned Cialis the moniker ‘the weekend pill’, as once the patient has taken a dose, the drug remains active for a whole day and a half.

So, for instance, a dose taken on Friday evening may still be functional all the way up to Sunday morning.

Contrary to what some might think however, this does not mean that an erection will be present for the whole duration of action; rather that the user will be able to achieve an erection when sexually stimulated during the time that Cialis is working.

Other oral tablet medicines may only remain active for four to six hours. Topical agents and urethral suppositories, although they get to work within minutes, may only have an effect which lasts for one or two hours.

In terms of durational efficacy, Cialis is currently the undisputed market leader.

Spontaneity

Another advantage of Cialis, and even more so of Cialis Daily, is that it allows the user to be spontaneous.

Cialis takes 30-60 minutes to work, but after this is functional for up to 36 hours. That means that once the treatment has begun to work, the user does not have to interrupt foreplay in order to take a pill, or apply a device or topical agent; once sexually stimulated, they’re ‘ready to go’.

Furthermore, those who take Cialis Daily, which contains a smaller dose but is designed to be taken once a day, do not have to wait 30-60 minutes for the tablet to work. This medicine remains functional 24 hours a day, and is suitable for those men who plan to have sex three (or more) times over the course of a week.

Some may see taking a tablet every day as a minor drawback, whereas others may prefer doing so and incorporating ED treatment into their routine.

Because it doesn’t require ‘on-demand’ administration, Cialis Daily is considered by many to be the closest of all ED medications currently on the market to being an ‘instant’ treatment.

Efficacy of Cialis

Cialis performs strongly among its competitors in terms of efficacy.

There are two doses of Cialis available (10 and 20mg), and two doses of Cialis Daily (2.5mg and 5mg). As one would expect, these different doses have reported different efficacy rates in clinical trials:

In one study, 10mg and 20mg doses of Cialis resulted in erections potent enough for vaginal penetration in 73 and 81 per cent of cases respectively; and resulted in erections strong enough to complete intercourse in 59 and 71 per cent of cases respectively.

Cialis on demand then has a comparable success level to sildenafil (perhaps the most established drug on the market for ED), which in clinical trials reported 63, 74 and 82 percent effectiveness rates respectively for the 25mg, 50mg and 100mg doses. 

Ease of Use

Measured against alprostadil, an injectable treatment for impotence, oral tadalafil tablets have performed slightly less favourably in clinical studies; alprostadil delivered via injection has been shown to have a 90 percent efficacy rate.

However, as an oral tablet, Cialis is a much easier treatment to take; and only needs to be applied once when taken on-demand to provide 36 hours of erectile potency.

Likelihood of Side Effects

It has been noted by some experts that tadalafil is a more selective enzyme inhibitor than some of its contemporaries. Sildenafil and vardenafil have also been found to exert inhibiting qualities over PDE6, an enzyme found in the eye, and PDE1, which is present in the brain and heart.

Tadalafil does inhibit these enzymes too, but to a much lesser extent. It has been theorised that tadalafil may be less likely to cause side effects such as disturbed vision, vasodilation and tachycardia as a result.
