Cialis (tadalafil) & Viagra (sildenafil) are said to be oral drugs that are used for treating ED (the inability to attain or maintain a penile erection) & benign prostatic hyperplasia (BPH) in men. They are in a group of drugs known as phosphodiesterase-5 (PDE5) inhibitors that also involve vardenafil (Levitra, Staxyn ODT), and avanafil (Stendra).
Moreover, The erection of the penile is caused by the engorgement of the penile area with blood. Under normal situations, sexual stimulation leads to the formation & release of nitric oxide in the penile area. Nitric oxide then activates the enzyme, guanylate cyclase, which later causes the formation of cyclic guanosine monophosphate (cGMP).
It is the cGMP that is responsible for the penile erection by affecting the blood that the blood vessels deliver & remove from the penile area. Cialis and Viagra inhibit an enzyme known as phosphodiesterase-5 (PDE5) which damages the cGMP. Cialis and Viagra thus prevent the destruction of cGMP & later allow cGMP to accumulate and stay for a longer time. The longer cGMP persists. The more prolonged the engorgement of the penile will be.
What is the dosage of Cialis vs. Viagra?
Cialis
For many individuals, the suggested initial dose of tadalafil is 10 mg each day that is taken before starting with sexual activity (tadalafil for use as needed).
Depending on the response or the side effects, the dose may be enhanced to 20 mg or reduced to 5 mg per day. The effect of tadalafil may stay for up to 36 hours. Men who are taking oral medications that enhance the blood levels of tadalafil should make sure that they don’t exceed a dose of 10 mg within 72 hours. For daily usage without regard to any kind of sexual activity, the suggested dose is up to 2.5 to 5 mg daily.
Especially, Tadalafil should not be consumed more than once every day. The recommended dose for BPH and ED is 5 mg each day which has to be taken at about the same time. To clarify, Tadalafil may be taken with or without consuming food since food does not affect its absorption right from the intestine. The tadalafil dose may need adjustment for patients with reduced liver or kidney function.

It is also not advised that you take either Sildenafil or take either Tadalafil along with alcohol. Because it can cause a drop in the overall blood pressure and may blunt the response of the drugs by impacting the blood flow and the libido. Moreover, If you are about to take either of these drugs for treating ED. Make sure to discuss it with an online clinician. This is true if you have any heart problems.
