Sulfapyridine (

antibacterial drug, but its water solubility is very pH dependent. Thus there is a risk of crystallization within the bladder or urethra, which could lead to pain or blockage. As with other sulfonamides, there is a significant risk of agranulocytosis
, and this, rather than the development of resistance by bacteria, is the main reason for its decline in use.

History

M&B 693 was one of the first generation of sulfonamide antibiotics. It was discovered by Lionel Whitby at the British firm May & Baker Ltd and logged in their Test Book on 2 November, 1937 under Code No M&B 693.

During the aftermath to the disastrous convoy SC7, in October 1940, Surgeon-Lieutenant John Robertson, RN, of HMS Leith, saved the life of Commodore Lachlan MacKinnon, from the torpedoed Assyrian, who had developed pneumonia, by giving him M&B 693, despite Robertson never having used it before and not knowing the required dosage.[2]

M&B 693 was successfully used to treat Winston Churchill's bacterial pneumonia.[3][4]

The same source records that in 1944 M&B 693 also saved Nero, the Royal Circus lion, from pneumonia.[5]

It could either be taken in tablet form or the powder could be placed in wounds. It was used so widely during the Second World War that May & Baker had difficulty keeping up with demand. It was later largely superseded by penicillin and other sulfonamides.
