On the other side of the planet, the 1960 BMJ letter linking thalidomide to peripheral neuritis caught the eye of William McBride, a young Australian obstetrician at the Women’s Hospital in Sydney. , the UK company that was licensed to market thalidomide throughout the British Commonwealth, McBride was impressed by the hypnosedative actions of thalidomide after prescribing it to a pregnant woman under his care. Although that mother gave birth to a healthy child, a cluster of severe birth abnormalities in the offspring of three other women to whom he also gave thalidomide caused Dr McBride growing concern.
Fig. 5 Adulteration of alcoholic beverages with TOCP during the 1930s Prohibition Era in America led to a distressing epidemic of peripheral neuropathy meant barbiturates were not ideal insomnia therapies, so hopes were raised when a fledgling German company, Chemie Grunenthal, began marketing a new hypnosedative – thalidomide – by claiming it lacked toxic effects and was safe for use in pregnancy. The grounds for the latter claim are questionable since little evidence exists for safety testing in pregnant animals or humans prior to thalidomide release.
During the late 1950s, evidence began emerging which suggested thalidomide was less safe than early marketing materials claimed. For example, long-term users developed a neurotoxic syndrome that in some ways resembled problems seen earlier in Ginger Jake victims: patients reported unpleasant tingling in their upper and lower limbs that sometimes progressed to numbness, muscle paralysis and difficulty in walking. 5 Modern Toxicological Disasters 15 syndrome in isolated patients appeared in various medical journals.
