Cialis Professional, which may also be labeled as “Tadalafil Chewable Tablets”, is a medication used to treat erectile dysfunction. According to the manufacturer, it is an improved and reformulated version of the original Cialis. In particular, Cialis Professional has been formulated to be fast-acting, due to an increased absorption rate of the effective ingredient.
The active ingredient in Cialis Professional tablets is either 40mg or 20mg of Tadalafil. Directions for use are identical to the original Cialis. One tablet should be taken by the patient 30 minutes prior to sexual intercourse. No more than one tablet should be taken in 24 hours, and it should not be taken together with any other erectile dysfunction medication. Tadalafil also has harmful interactions with certain other medications. Use of Tadalafil is contraindicated for people who take nitrates or medications to treat pulmonary hypertension.
Compared to other medication for erectile dysfunction, such as Levitra or Viagra, Cialis Professional has a significantly longer duration, with a half-life of 17.5 hours instead of 4-5 hours for Levitra and Viagra, and can remain effective for up to 36 hours. In addition to its use for erectile dysfunction, Tadalafil may be prescribed for treatment of pulmonary arterial hypertension and benign prostatic hyperplasia, particularly when benign prostatic hyperplasia coincides with erectile dysfunction.
Tadalafil acts by inhibiting the PDE5 enzyme, which increases the amount of cyclic guanosine monophosphate (cGMP). cGMP relaxes the smooth muscle in arteries leading to the penis, enhancing blood flow and improving erectile function. While the active ingredients in Levitra and Viagra (vardenafil and sildenafil) operate by the same mechanism, Tadanafil has higher selectivity, which means that it does not affect other enzymes, and has fewer side effects. In particular, compared to other erectile dysfunction medications, Tadanafil has less inhibitory effect on the PDE1 or PDE6 enzymes, so it the side effects of light sensitivity, flushing or increased heart rate that are common with the other medications are less severe.
However, Cialis Professional, as all drugs containing Tadalafil, are not completely free of side effects. Possible side effects include flushing in the face or chest, cold-like symptoms such as a stuffy nose, headache, diarrhea and muscle or back pain. These side effects normally resolve themselves in a few hours. Occasionally, Cialis may cause a prolonged or painful erection. In this case, if the erection does not subside in four hours, medical attention is required. In very rare cases, Cialis Professional may cause a severe allergic reaction, or dangerous cardiovascular or neurological problems. A person who experiences hives, swelling, difficulty breathing, chest pain, pain radiating down the arm, irregular heartbeat, changes or loss of vision, ringing in the ears or loss of hearing, shortness of breath, or seizures should immediately seek emergency medical help.
In South Africa, Cialis Professional may be purchased at an online pharmacy without a prescription. However, there have been some problems with counterfeit pills when ordering from disreputable online pharmacies. If at all possible, it is highly recommended that Cialis Professional be purchased at an online pharmacy that requires a prescription, or at a store-based pharmacy.
