Distribution: the average volume of distribution of about 63 liters, that tadalafil distribution into tissues. In the treatment, plasma concentration within 94% of tadalafil and protein binding. Protein binding is not affected by the impairment of renal function.

Clear: in healthy subjects with oral tadalafil average removal rate of 2..5L/hr, the average half-life of 17.5 hours. Tadalafil mainly metabolites excreted free activity, mainly from the feces (about 61% of the dose), little part is excreted in the urine (about 36% of the dose).
