Cialis is very similar to the popular ED medication Viagra, with the biggest difference being the drug’s active life. Cialis will produce erections for 36-48 hours from one single dose where Viagra is limited to 4-6 hours from one single dose. Cialis is also prescribed for the treatment of BPH (Benign Prostatic Hyperplasia), which refers to an enlarged prostate that results in difficulty or frequent urination. Due to the long half-life and even longer active life, Cialis is commonly referred to as “The Weekend Pill”. Tadalafil (cialis) belongs to the class of drugs known as phosphodiesterase type 5 inhibitors (PED5 Inhibitor). The PED5 does not produce erections on its own, sexual stimulation must still exist, but it will ensure an erection can be maintained if blood flow issues were preventing it before.
Cialis, as with other common PED5 inhibitors functions by increasing the blood flow to the penis. The penile arteries are relaxed and nitric oxide is released via the nerves to the endothelial cells into the penis. This action promotes the synthesis of cGMP thereby resulting in a fuller, stronger and longer lasting erection. Those who suffer from ED may do so in a way that prevents them from obtaining an erection or they may be able to obtain one but unable to maintain it due to poor penile blood flow. Cialis will remedy such blood flow issues.
There are side effects of Cialis, possible side effects, but they are not guaranteed and normally dependent on genetics and dosing if too much is taken. Cialis has the lowest rate of incident among PED5’s. Other possible yet infrequent side effects of Cialis may include:
- Sore Muscles
- Lower Back Pain
The above side effects of Cialis should last no more than a few hours if they occur and are due to the drugs ability to widen blood vessels. If such effects occur most men will find a lower dose fixes the problem.
