DPP-4 inhibitor
Is Sitagliptin vegetarian or vegan-friendly?
Vegetarian and vegan patients sometimes ask whether their medication contains animal-derived ingredients. The active substance Sitagliptin in Sitagliptin is almost always synthetically produced; the question typically concerns excipients in the tablet or capsule shell at 25mg, 50mg, 100mg.
Animal-derived excipients in Sitagliptin
Common animal-derived excipients in pharmaceuticals include gelatin (in capsule shells, derived from porcine or bovine sources), lactose (dairy-derived), and certain magnesium stearate sources. The prescribing information and patient leaflet for Sitagliptin list excipients; whether they are animal-derived is sometimes specified, sometimes left ambiguous. 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).
Practical guidance
According to general pharmacy practice, vegetarians and vegans concerned about Sitagliptin excipients should ask the pharmacist or manufacturer directly. Many medications have authorised generic versions with different excipient profiles — switching to a generic of Sitagliptin with vegetable-derived excipients is sometimes possible at 25mg, 50mg, 100mg. For strict requirements (e.g. religious or strong ethical), specialist pharmacy consultation gives definitive answers.
Frequently asked questions
