Single administration of atenolol does not influence the kinetics of orally given isosorbide dinitrate.
In eight subjects, plasma concentrations of isosorbide dinitrate and its mononitrates after oral administration of 10 mg isosorbide dinitrate were measured on two occasions, once with and once without previous administration of a single dose of atenolol 100 mg. There were no significant changes either in plasma concentration at different times after administration, or in peak plasma concentrations or in area under the curve of the isosorbide dinitrate and mononitrates.
