Inhalation solutions — Which ones may be mixed? Physico-chemical compatibility of drug solutions in nebulizers — Update 2013

2014

AbstractMany patients suffering from chronic respiratory diseases rely on inhalation therapy with nebulizers. About 25% of patients who need to inhale several different drugs per day save time by mixing them for simultaneous inhalation. This review presents a comprehensive overview of the available data concerning physico-chemical compatibility of commonly mixed nebulizer solutions and suspensions. Information is based on our in vitro studies and a thorough literature search.Results indicate that many nebulizer solutions/suspensions are mixable without provoking incompatibilities. However, certain excipients contained in some of the tested drug products could be identified as a reason for i…
