Semaglutide and Nonarteritic Anterior Ischemic Optic Neuropathy: Synthesizing Evidence from Target Trial Emulations and Global Pharmacovigilance

Semaglutide and Nonarteritic Anterior Ischemic Optic Neuropathy: Synthesizing Evidence from Target Trial Emulations and Global Pharmacovigilance

This review synthesizes recent evidence regarding the association between semaglutide initiation and nonarteritic anterior ischemic optic neuropathy (NAION), contrasting high-risk findings in real-world cohort studies with neutral findings in RCT meta-analyses and exploring potential mechanistic pathways.

Immune Checkpoint Inhibitors Amplify Risk and Delay Onset of SJS/TEN: Evidence for a Two‑Hit Mechanism

A large FAERS analysis links immune checkpoint inhibitors (ICIs) to markedly increased SJS/TEN risk, demonstrates additive synergy with high‑risk small molecules, and shows delayed latency particularly with anti–PD‑1 agents — supporting a two‑hit, T‑cell–mediated model and urging cautious coprescribing and prospective study.
