Tadalafil

Therapeutic considerations
Since PDE5 inhibitors such as tadalafil may cause transiently low blood pressure (hypotension), organic nitrates should not be taken for at least 48 hours after taking the last dose of tadalafil. Using organic nitrates (such as the sex drug Amyl nitrite) within this timeframe may increase the risk of life-threatening hypotension.

Half life 17.5 hours
The most common side effects when using tadalafil are headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose. These side effects usually go away after a few hours. Patients who get back pain and muscle aches usually get it 12 to 24 hours after taking the drug, and the symptom usually goes away after 48 hours.
[edit]
Some individuals with the surname of "Cialis" objected to the naming of Lilly's drug, but the pharmaceutical giant insists that the drug's name has nothing to do with the surname. [2]

It works by inhibiting an enzyme known as PDE5. A 20 mg dose of Tadalafil is comparable to a 100 mg dose of sildenafil (Viagra).
3 Side effects
[edit]
Tadalafil is a drug used to treat male erectile dysfunction (impotence). It was developed by the biotechnology firm ICOS and marketed worldwide by Eli Lilly and Company under the brand name Cialis.
4 Drug interactions - organic nitrates
Since people who have taken tadalafil within the past 48 hours cannot take organic nitrates to relieve angina (GTN Spray), these patients should seek immediate medical attention if they experience anginal chest pain [1]. In the event of a medical emergency, paramedics and medical personnel should be notified of any recent doses of tadalafil.

CAS number 171596-29-5
Marketing
In May 2005, the U.S. Food and Drug Administration found that tadalafil (along with other PDE5 inhibitors) could lead to vision impairment in certain patient groups, including diabetics. An investigation is currently ongoing.
