Tadalafil 20 mg

How does Cialis work?

An erection happens when the male sexual organ fills with blood. That transpires because of the arteries that transport blood to the male sexual organ expand, intensifying the supply itself. Simultaneously, the arteries that eliminate blood from the male sexual organ tighten. The blood builds up in the penis, leading to an erection.

Once a person receives sufficient sexual stimulus, nitrogen monoxide is discharged. Nitrogen monoxide aids the creation of guanosine cyclic monophosphate, which influences the expansion and narrowing of the arteries that transport blood to/from the penis.

Another element, cGMP-specific phosphodiesterase type 5, wipes out guanosine cyclic monophosphate. The minute it happens, the arteries go back to their usual proportions, and the erection stops. Cialis prevents cGMP-specific phosphodiesterase type 5 from wiping out guanosine cyclic monophosphate. That leads to erections that last longer.

Who shouldn't take Cialis?

Don't take it in case:

• You have an allergy to Tadalafil or any components of this medicine;
• You have ocular issues;
• You are currently taking Adempas or a similar drug;
• You are taking any kind of nitrate-based pharmaceuticals.

When on the subject of possible undesirable reactions, there are three most commonly reported side-effects:

• Vertigo;
• Queasiness;
• Lack of sensation, slight tingling or outright discomfort in the limbs.

In case your erection persists for more than 320 minutes, you should immediately contact the nearest medical facility. This type of unwanted response can cause permanent damage to your reproductive organs.

Rarely, this medication can destabilize the supply of blood to the cranial nerve II in the eye, leading to unexpected bouts of blindness. The users that are at a higher risk for such severe adverse reaction are the ones suffering from high blood pressure, diabetes mellitus, hypercholesterolemia, underlying issues with eyes or cardiovascular illnesses.

It should be noted that over 90% of people using this medication report no side-effects whatsoever.
