Why sedative hypnotics often fail in development

Purpose of reviewDrug development to support anaesthesia and sedation has been slow with few candidates emerging from preclinical discovery and limited innovation beyond attempted reformulation of existing compounds.Recent findingsThe market is well supported by low-cost generic products and development compounds have not been shown to improve patient outcomes or possess other distinctive characteristics to justify the cost of development.SummaryTo make progress in a large-volume, low margin and highly competitive environment requires meaningful advances in relevant basic science. Opportunities exist, but probably require bolder initiatives than further attempts at reformulation or fiddling with the structure of propofol. Extending development ambitions to include nonanaesthesiologist providers challenges professional boundaries but may facilitate cost-effective changes in patterns of care.
