Mechanisms compared
Avodart: Avodart inhibits both isoforms of 5α-reductase, the enzyme that converts testosterone to dihydrotestosterone (DHT). Sitagliptin: Sitagliptin reversibly inhibits DPP-4, the serine protease responsible for rapid degradation of glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP).
