id value
e
1 0.10 HOURS POST-DOSE
1 2 HOURS POST-DOSE

As long as you don't have brackets in brackets the following should do the job:
data have;
infile datalines truncover dlm='|';
input ID:$1. value $100.;
datalines;
1|0.10 (00 min) hours post-dose
1|2 (pre-2nd dose) (-2 min) hours post-dose
1|Pre-dose
;
run;
data sample;
set have;
length value_want $100;
value_want=prxchange('s/\s*\(.*\)\s*/ /oi',-1,value);
run;
