10 Synthesis and future outlook: rediscovering dormant biology in the era of peptide engineering The cumulative evidence reviewed across metabolic, appetite-regulatory, bonemusclefat, neuroendocrine, and immunemetabolic peptide systems support a unifying conclusion: the apparent scarcity of transformative peptide therapeutics is not a consequence of limited biological opportunity, but rather of historical constraints in pharmacologic execution, translational strategy, and conceptual framing
In Vivo Assessment of Drug Interactions Effects of Sitagliptin on Other Drugs In clinical studies, sitagliptin did not meaningfully alter the pharmacokinetics of metformin, glyburide, simvastatin, rosiglitazone, digoxin, warfarin, or an oral contraceptive (ethinyl estradiol and norethindrone) (Table 4), providing in vivo evidence of a low propensity for causing drug interactions with substrates of CYP3A4, CYP2C8, CYP2C9, P-gp, and organic cationic transporter (OCT)
