The present invention relates to derivatives of tadalafil, substituted with deuterium on the methylene carbon atom situated between the oxygens of the benzodioxol ring, and optionally further substituted with deuterium atoms in place of normally abundant hydrogen, and 13C in place of normally abundant 12C. These compounds are selective PDE5 inhibitors and possess advantageous biopharmaceutical and pharmacokinetic properties. The invention further provides compositions comprising these compounds and methods of treating diseases and conditions that are responsive to PDE5 inhibition, alone and in combination with additional agents.
