Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are peptide-derived analogs that were initially investigated to treat type 2 diabetes. Recently, a drug targeting the receptors of both GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) (tirzepatide) has been introduced market, its indications have expanded include treating obesity. Here, we review pharmacokinetics, pharmacokinetic drug-drug interactions (DDIs), modeling approaches four currently available RAs (exenatide, liraglutide, dulaglutide, semaglutide) tirzepatide. To address extremely short half-life (2 min) native human GLP-1, structural modifications applied dual GLP-1/GIP RA. These amino acid sequence substitutions, fatty conjugation using linker, fusion with albumin or IgG fragment crystallizable (Fc) region, resulting in minimal metabolism renal excretion. Due their diverse structures, profiles vary, prolonged may be associated an increased risk adverse events. Clinically significant drug-metabolizing enzyme- transporter-mediated DDIs yet reported. Mechanism-of-action-mediated limited those involving delayed gastric emptying, most studies found them clinically insignificant. However, changes exposure observed for oral contraceptives levothyroxine following administration tirzepatide semaglutide, respectively, indicating need close monitoring these instances. Thirty models developed predict pharmacokinetics physiologically based can useful assessing mechanism-of-action-mediated DDIs. Alterations volume distribution clearance from other mechanisms action (eg, reduced fat mass, cytochrome P450 activity, glomerular filtration rate) key factors determining pharmacokinetics. mediated by remain poorly understood require further investigation ensure safely used concomitant medications.
