Pharmaceutical company, a division of GlaxoSmithKline (thanks to recent merger), which was once GlaxoWellcome and SmithKline-Beecham.
Makes Piriton antihistamines, but mostly makes dental products such as Sensodyne toothpaste. Noders in the UK will probably have had a hard time escaping those adverts for PoliGrip Ultra denture glue; that appears to be one of their main products. Thanks to Stafford-Miller, we can all eat crusty bread when we're eighty.
