How does one get achieve an erection? How does Cialis work?
Erection is achieved as the penis is filled with blood. This is achieved due to the fact that the blood vessels responsible for bringing blood to the penis dilate and as a result penis blood supply increases. At the same time, contraction occurs at the blood vessels which are responsible for getting blood out of the penis contract and as a result a lot of blood is gathered in the penis (having erection as the final result).
At the point when a male is sexually aroused, the penis receives another substance called nitric oxide. Nitric oxide triggers a cascade of responses – it makes an enzyme, guanylate cyclase deliver cGMP (cyclic guanosine monophosphate) . cGMP manages the constriction and widening (enlargement) of veins that convey blood to and from the penis. The chemical response makes the vessels that supply the penis enlarge, while those expelling blood from the penis contract, bringing about an erection.
cGMP is catalyzed by another enzyme which is called phosphodiesterase-5. When this takes place erection ends due to the blood vessels returning to their initial size. Tadafil prolongs CGMP’s function by inhibiting PDE5’s action towards cGMP, which helps to maintain an erection for longer.
Crucial Cialis information you need to be wary of
Combining Cialis with nitrate medicaments may lead to a serious and sudden blood pressure drop (hypotension). Do not combine Tadafil with nitrate prescription medication during the treatment of heart conditions or chest pain.
If you come to experience dizziness, nausea, numbness, tingling, jaw, arm, neck or chest pain during sexual intercourse you need to stop and contact your doctor at once. This may be a very rare and serious adverse effect of Cialis
If using Cialis gives you a painful or extremely prolonged erection (for more than an hour) you shall seek medical attention. Your penis can be damaged during priapism (prolonged erection).
In rare occasions, Cialis can alter optic nerve blood flow and cause sudden vision loss. This usually happens with patients who suffer from hypertention, diabetes, elevated cholesterol levels, eye illness and hear problems. Experts cannot determine whether tadafil is responsible for the vision loss or something else causes it.
Unless your physician approves it, you shall not take Cialis if you are suffering from the conditions listed below:
Heart rhythm issues
Congestive heart failure or stroke that occurred within the last few months
Blood conditions such as sickle cell anemia, multiple myeloma, leukemia etc.
Patients with hemophilia
Liver or kidney conditions
Retinitis pigmentosa state
Structural penis deformity issues such as Peyrnie’s disease
A history of congenital or acquired heart disease
Health contraindications to having sexual intercourses
Angina pectoris and/or high or low blood pressure
