Tailored therapy in asthma? ADRB2 genotype in the context of salmeterol therapy
In a recent trial, asthmatic children homozygous for the beta2-adrenergic receptor Arg16 variant (ADRB2 gene, rs1042713 genotype AA) were randomized and treated with either salmeterol (a beta2-adrenergic receptor agonist) or montelukast (a leukotriene receptor antagonist), both combined with fluticasone. Those in the montelukast treatment group displayed significantly better responses in
