For reliable interpretation of results, collect samples either after the drug's distribution phase or immediately before the next oral dose. To accurately refelct the drug in the myocardium and to evaluate cardiac response it is recommended to collect samples 6 hours after oral dose or 4 hours after intravenous dose.
