In October 2007, the fda announced that the labeling for all pde5 inhibitors, including tadalafil, requires a more prominent warning of the potential risk of sudden hearing loss as the result of postmarketing reports of deafness associated with use of pde5 inhibitors. 4 Drug interactions edit since pde5 inhibitors such as tadalafil may cause transiently low blood pressure ( hypotension alkyl nitrites ( poppers ) should not be taken for at least 48 hours after taking the last dose of tadalafil. Using poppers (such as the sex drug amyl nitrite ) within this timeframe may increase the risk of life-threatening hypotension. Since people who have taken tadalafil within the past 48 hours cannot take organic nitrates to relieve angina (such as glyceryl trinitrate spray these patients should seek immediate medical attention if they experience anginal chest pain. 5 In the event of a medical emergency, paramedics and medical personnel should be notified of any recent doses of tadalafil. Tadalafil is metabolized predominantly by the hepatic cyp3A4 enzyme system. The presence of other drugs which induce this system can shorten tadalafil half-life and reduce serum levels, and hence efficacy, of the drug.

tadalafil 20 mg uses associated with vision impairment related to naion ( non-arteritic anterior ischemic optic neuropathy ) in certain patients taking these drugs in the post-marketing (outside of clinical trials) setting. Most, but not all, of these patients had underlying anatomic or vascular risk factors for development of naion unrelated to pde5 use, including: low cup to disc ratio crowded disc age over 50, diabetes, hypertension, coronary artery disease, hyperlipidemia and smoking. Given the small number of naion events with pde5 use (fewer than one in one million the large number of users of pde5 inhibitors (millions) and the fact that this event occurs in a similar population to those who do not take these medicines, the. However, the label of all three pde5 inhibitors was changed to alert clinicians to a possible association.

Tadalafil is excreted mostly as inactive metabolites, mainly in the faeces (approximately 61 of the dose) and to a lesser in the urine (approximately 36 of the dose). Healthy elderly patients, over age of 65 or over showed a lower oral clearance of Tadalafil, resulting in 25 higher exposure (AUC) relative to healthy patients aged between 19 and 45 years old.
