Co-amoxiclav
Co-amoxiclav was identified in 1972 by a group of scientists in Beecham (now GlaxoSmithKline). It was launched as Augmentin in the UK in 1981 and it is a combination of clavulanic acid and Amoxicillin. It is now on the World Health Organisation's list of Essential Medicines meaning it is very important in modern medicine.
