One option is a DATA step to read up your variables, then using a DO DT=start_date TO end_date; / END; loop you can increment your date value using the INTNX function with the "SAMEDAY" parameter argument and OUTPUT additional observations for some number of INTNX interval periods (another function argument).

I am not so sure about what actually your question really is. But you may try below code. I hope this one could help.

data DosePerDay(drop=start dd);
format patientid $3.;
format date ddmmyy8.;
format dose $4.;
start=mdy(3,1,2009);
do dd=start to start + 30;
patientid="101";
date=dd;
dose="10mg";
output;
end;
run;

proc print data=DosePerDay noobs;
run;
