C.Pseudoephidrine
D.Enalapril
E.Ranitidine
A perhaps?
B is a thiazide diuretic... C is an a1 adrenoreceptor agonist... D is an ACE inhibitor but i've never heard of E...
I think that Propranolol antagonises beta 2 adrenoreceptors, which causes bronchoconstriction... and this would explain the wheeze... not sure though...
