Key differences
Symbicort belongs to Respiratory Medications while Januvia belongs to Diabetes Treatment. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Symbicort: Budesonide reduces chronic airway inflammation through glucocorticoid receptor activation, decreasing inflammatory cell recruitment and cytokine release. Januvia: Sitagliptin reversibly inhibits DPP-4, the enzyme responsible for rapid degradation of GLP-1 and GIP.
When Symbicort is preferred
Symbicort is approved in adults and adolescents from age 12 (younger in some markets) for the regular treatment of asthma when combination therapy of a long-acting beta-2 agonist and an inhaled corticosteroid is appropriate, and in some markets for symptom relief in COPD.
When Januvia is preferred
The medication is indicated in adults with type 2 diabetes mellitus, alone or in combination with other antidiabetic agents, to improve glycaemic control.
