Therapeutic Escalation, Treatment Intensification, and Modification Patterns in Patients Receiving Antidiabetic Therapy

Background: The progressive nature of type 2 diabetes mellitus frequently necessitates therapeutic intensification, treatment modification, and regimen optimization to achieve sustained glycaemic control and minimize long-term complications. Evaluating patterns of therapeutic escalation provides valuable insights into real-world prescribing practices and disease management strategies. Objective: To assess therapeutic escalation, treatment intensification, dose modification, and prescription adaptation patterns among patients receiving antidiabetic therapy in routine clinical practice. Methods: A cross-sectional observational study was conducted involving 400 patients receiving antidiabetic treatment. Demographic characteristics, therapeutic escalation status, utilization of fixed-dose and free-drug combinations, drug-switching practices, add-on therapy patterns, and dose-adjustment trends were systematically evaluated using structured prescription review and patient record analysis. Descriptive statistical methods were employed to summarize treatment modification patterns. Results: Male patients predominated the study population (60.0%), with the highest representation observed in the 46–55-year age category (27.5%). Therapeutic escalation analysis demonstrated that second-line intensification constituted the most prevalent treatment strategy (43.25%), followed by first-line therapy maintenance (31.5%), third-line escalation (20.25%), and advanced or complex therapeutic regimens (5.0%). Free-drug combinations were prescribed slightly more frequently than fixed-dose combinations (53.25% vs. 46.75%). Nearly half of the patients (49.0%) exhibited no treatment modification during follow-up, whereas add-on therapy (37.5%) was substantially more common than drug switching (13.5%). Dose-adjustment evaluation revealed that 61.0% of prescriptions remained unchanged, while dose escalation and dose reduction were observed in 25.5% and 13.5% of patients, respectively. Conclusion: The findings underscore a substantial reliance on second-line therapeutic intensification and add-on treatment strategies in contemporary diabetes management. The predominance of regimen augmentation over drug substitution highlights clinicians’ preference for progressive pharmacotherapeutic optimization, emphasizing individualized treatment approaches aimed at achieving durable glycaemic control and improved clinical outcomes.
