BACKGROUND: Drug repositioning refers to the process of developing new
indications for existing drugs. As a phenotypic indicator of drug response in
humans, clinical side effects may provide straightforward signals and unique
opportunities for drug repositioning. OBJECTIVE: We aimed to identify drugs
frequently associated with hypotension adverse reactions (ie, the opposite
condition of hypertension), which could be potential candidates as
antihypertensive agents. METHODS: We systematically searched the electronic
records of the US Food and Drug Administration (FDA) Adverse Event Reporting
System (FAERS) through the openFDA platform to assess the association between
hypotension incidence and antihypertensive therapeutic effect regarding a list of
683 drugs. RESULTS: Statistical analysis of FAERS data demonstrated that those
drugs frequently co-occurring with hypotension events were more likely to have
antihypertensive activity. Ranked by the statistical significance of frequent
hypotension reporting, the well-known antihypertensive drugs were effectively
distinguished from others (with an area under the receiver operating
characteristic curve > 0.80 and a normalized discounted cumulative gain of 0.77).
In addition, we found a series of antihypertensive agents (particularly drugs
originally developed for treating nervous system diseases) among the drugs with
top significant reporting, suggesting the good potential of Web-based and
data-driven drug repositioning. CONCLUSIONS: We found several candidate agents
among the hypotension-related drugs on our list that may be redirected for
lowering blood pressure. More important, we showed that a pharmacovigilance
system could alternatively be used to identify antihypertensive agents and
sustainably create opportunities for drug repositioning.
