Precision Medicine in Weight Loss: Leveraging Pharmacogenomics to Tailor Semaglutide and Tirzepatide Therapy
Emerging evidence underscores the transformative potential of pharmacogenomic profiling to individualize treatment with GLP-1 receptor agonists such as Semaglutide and dual agonists like Tirzepatide. Variability in drug response often stems from genetic polymorphisms affecting receptor sensitivity, drug metabolism, and downstream signaling pathways involved in appetite regulation and glucose homeostasis. By integrating genomic data, clinicians can predict therapeutic efficacy and adverse event risk, thereby optimizing dosing regimens and minimizing trial-and-error approaches.
For example, polymorphisms within the GLP-1 receptor gene (GLP1R) or genes encoding G-protein coupled receptor kinases may modulate receptor desensitization, influencing both weight loss magnitude and gastrointestinal tolerability profiles. Additionally, cytochrome P450 enzyme variants may alter drug pharmacokinetics, necessitating adjustments in titration speed or maintenance doses to balance effectiveness with safety.
Such personalized strategies align with precision obesity medicine paradigms, moving beyond traditional one-size-fits-all prescriptions toward nuanced, data-driven care.
