“…Cross-sensitivity or cross-reactivity occurs when drugs of the same class (often with similar structures) have nearly identical toxicity profiles in the same patients. This possibility justifies avoiding the use of such cross-reacting medicines as much as possible [ 56 , 57 ]. Examples of drug classes that exhibit cross-sensitivity include aromatic anticonvulsants, angiotensin-converting enzyme (ACE) inhibitors, propionate NSAIDs, tricyclic antidepressants (TCAs), erythromycin, phenothiazines, and haloalkane anesthetics [ 56 , 57 ].…”
