Renal impairment: what the trials found

In studies evaluating Tadalafil for renal-related outcomes, results regarding its impact on urinary sodium excretion were inconsistent. One trial showed no significant change in urinary sodium excretion (p=0.8) 4, while another study reported a statistically significant increase in urinary sodium excretion (p=0.04) 5.

Clinical evaluations of Tadalafil did not find significant changes in Glomerular Filtration Rate (GFR) (p=0.25) or Urinary Cyclic Guanosine 3',5'-Monophosphate (cGMP) Hormone Excretion (p=0.32) 4.

Recent results — preliminary, needs further review

  • MK-8527-TP was evaluated in patients with moderate and severe renal impairment, showing specific concentrations in PBMCs at 672 hours (C672) of 0.183, 0.248 1.
  • Pharmacokinetic data for PA-824 were established regarding M19 and M50 concentration time-curves and maximum concentrations across various time points 9.
  • mpMRI was evaluated in a Phase 1 study 8.

For the clinician treating this condition

  • Evidence regarding Tadalafil's effect on urinary sodium excretion is conflicting, with one study showing significant increase while another showed no change.
  • Tadalafil did not demonstrate statistically significant changes in GFR or urinary cGMP hormone excretion in the studied cohorts.
