Let's say that patient A is taking drugs like as shown below
|---atenolol-----esmolol----nebivolol---------------------|
|---s------e-----s-----e----s-------e---------------------|
here s
and e
indicates start and end date of drugs, meaning a patient started with atenolol first....after completing atenolol course, he started esmolol....after finishing esmolol, he started nebivolol...
So now, am I right to understand that patient was in monotherapy treatment throughout?
Though he had multiple drugs (which belonged to the same class) at different time points, he was on monotherapy. Am I right to understand this?
