Is pseudoephedrine on the list of doping products ? This is normally used in case you are coughing ...
It's a stimulant, like all of the adrenaline/ephedrine-derivatives, and it's on the WADA list for sure.
BTW, athletes are allowed to take these if they can proof the doping institutions that it's for proper medical purpose, i.e. on doctor's prescription (like many athletes suffering from asthma-related diseases do).
If Minar failed to do so, he's in trouble.
That said, the original article only said 'verdacht' - meaning suspected of. He's not condemned yet.
