Abstract: Objective To study the clinical manifestations of adverse drug reactions (ADR) caused by lappaconitine hydrobromide as reference for clinical rational drug use. Methods A total of 535 reports of new and serious ADR involving lappaconitine hydrobromide in Shandong Provincial ADR Database from January 1, 2011 to December 31, 2021 were retrospectively analyzed. Results The new and serious adverse reactions of lappaconitine hydrobromide were more prevalent in people ages 45~65, and most of the ADR occurred within one day of administration. The ADR of lappaconitine hydrobromide mainly presented as multiple systemic and organ damage such as gastrointestinal damage, systemic damage, and damage to the skin and its attachments. The risks of abnormal liver function, allergic reactions or anaphylactic shock were not mentioned in the instructions. Conclusion The warning in the instructions for preparations of lappaconitine hydrobromide is inadequate. Marketing authorization holders need to study post-marketing data and improve the instructions to ensure the safety of patients.

Key words: lappaconitine hydrobromide, rational drug use, adverse drug reaction(ADR), abnormal liver function, shock
