To evaluate the association between clinical determinants and the occurrence of adverse drug reactions in hospitalized patients who received tropicamide/phenylephrine 8 mg/50 mg/mL. An ambispective, interventional, longitudinal study will be conducted to actively identify adverse reactions to tropicamide/phenylephrine 8 mg/50 mg/mL, as well as the clinical determinants that may predispose patients to the occurrence of an adverse drug reaction (ADR). Data will be collected through the administration of a questionnaire and measurement of vital signs prior to the administration of tropicamide/phenylephrine 8 mg/50 mg/mL, and subsequently at 5 minutes, 15 minutes, 30 minutes, 1 hour, 2 hours after administration, with the aim of establishing an association between these variables.
