Transient pulmonary opacities/infiltrates (see also under Iav)

Last update 11/09/2026

(Fr: opacites pulmonaires transitoires dont le caractere labile les fait attribuer a un oedème pulmonaire a minima ou fugace avec ou sans vascularite). Short-lived opacities are thought to represent transiently increased pulmonary permeability, intersitial lung disease, or vasculitis. May relapse upon reexposure, sometimes in the form of a more severe pattern or an ARDS picture.

Causative drugs

Frequency - Incidence

Incidence of cardiac adverse event(s) due to the specific drug as assessed by number of reported/published cases in the literature. Red digits in stars indicate: 0 = Very rare, questionable signal · 1 = < 10 cases · 2 = 10-50 cases · 3 = 50–100 cases · 4 = 100-200 cases · 5 = >200 cases

Evidence level/grade

Evidence level for cardiac adverse event(s) due to the specific drug as estimated using Hill’s (1965), Naranjo’s (1981), and Bégaud’s (1985) criteria applied to published cases. Blue digits in stars indicate: 0 = Questionable · 1 = Low · 2 = Moderate · 3 = Robust · 4 = Definite · 5 = Unquestionable, pathognomonic
