Efficacy of Tirzepatide Dual <scp>GIP</scp> / <scp>GLP</scp> ‐1 Receptor Agonist in Patients With Idiopathic Intracranial Hypertension. A Real‐World Propensity Score‐Matched Study
Bibliographic record
Abstract
ABSTRACT Introduction Idiopathic intracranial hypertension (IIH) is a neurological disorder characterised by elevated intracranial pressure (ICP), predominantly affecting obese women of reproductive age. While GLP‐1 receptor agonists have shown promise in IIH management, the potential of dual GIP/GLP‐1 receptor activation through tirzepatide remains unexplored. This study aimed to evaluate tirzepatide's efficacy as an adjunctive therapy in IIH management. Methods We conducted a retrospective cohort analysis using the TriNetX Global Health Research Network, analysing data through November 2024. Through propensity score matching, we compared 193 tirzepatide‐exposed IIH patients with 193 controls receiving standard care. Primary outcomes included papilledema severity, visual function, headache frequency, and treatment resistance, monitored at multiple follow‐up timepoints. Results Our analysis revealed significant improvements across all measured outcomes in the tirzepatide group. At 24 months, we observed a 68% reduction in papilledema risk (RR 0.320, 95% CI 0.189–0.542, p < 0.001), a 73.9% reduction in visual disturbance and blindness risk (RR 0.261, 95% CI 0.143–0.477, p < 0.001), and a 19.7% reduction in headache risk (RR 0.803, 95% CI 0.668–0.966, p = 0.019). The tirzepatide group demonstrated significant body‐mass index reductions, reaching −1.147 kg/m 2 (95% CI [−1.415, −0.879], p < 0.001) at 24 months compared to controls. Conclusions Our results demonstrate that tirzepatide, when used as an adjunctive therapy, provides significant therapeutic benefits in IIH management, particularly in improving papilledema and visual outcomes. Our findings suggest that dual GIP/GLP‐1 receptor activation may offer advantages over traditional single‐receptor therapies, potentially through enhanced metabolic regulation and direct effects on ICP dynamics.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
