Penile erection is caused by the sexual stimulation which causes engorgement of the penis with blood. At that point the blood vessels delivering blood to the penis increase in size and increase the delivery of blood to the penis. At the same time, the blood vessels carrying blood away from the penis decrease in size and decrease the removal of blood from the penis. To accomplish this process nitric oxide is released into a penis. Nitric oxide then activates the enzyme, guanylate cyclase to produce cyclic guanosine monophosphate (cGMP). The cGMP is primarily responsible for increasing and decreasing the size of the blood vessels that carry blood to and from the penis. PDE5 inhibitors like Cialis (Tadalafil) prevent PDE5 (phosphodiesterase-5) enzyme from destroying cGMP, so that cGMP persists longer. The longer cGMP persists, the more prolonged the erection is.
Cialis (Tadalafil) is available as an oral drug, available in dosage of 5 mg, 10 mg and 20 mg. The dosage depends on your prescription. Physicians usually prescribe 10 mg of Cialis (Tadalafil) per day. This amount can be adjusted according to your reactions to 5 mg if you react to strong to 10 mg dosage or even 20 mg if you do not produce a strong enough reaction. Dosage can be changed only by your physician and depends on the individuals. Do not change your prescribed dosage yourselves. None of the PDE inhibitors on the market today should be taken more then once a day. Take Tadalafil exactly as it was prescribed for you. Do not take it in larger doses or for longer than recommended by your doctor.
Cialis (Tadalafil) is usually taken when needed at least an hour before sexual intercourse. Tadalafil is known as the “36 hour pill” or the “weekend pill” because unlike other similar drugs, Cialis has a long duration of effectiveness.
Tadalafil can be taken with or without food. Unlike its competitors which must be taken on an empty stomach, because a high fat meal is affects the rate of absorption, Cialis (Tadalafil) absorption rate is not affected by food. Also it is advisable to take each dose of Cialis (Tadalafil) with a full glass of water.
Avoid drinking alcohol prior and after taking Cialis (Tadalafil), which can increase some of the side effects. Also grapefruit and grapefruit juice may interact with Cialis (Tadalafil). Discuss the use of grapefruit products with your physician.
Tadalafil should only be taken only if your primary health care professional prescribes it for you. This is because Cialis (Tadalafil) can be dangerous if you take it at the same time as certain other medicines including some that are used to treat chest pain (angina), high blood pressure or prostate problems. In addition, it would be beneficial to mention to your physical any other over the counter medication or supplements you are currently consuming so contraindication or side effects would not occur.
