In 1901, Langley challenged the dominant hypothesis that drugs act at nerve endings by demonstrating that nicotine acted at sympathetic ganglia even after the degeneration of the severed preganglionic nerve endings. In 1905 he introduced the concept of a receptive substance on the surface of skeletal muscle that mediated the action of a drug. Langley postulated that these receptive substances were different in different species (citing the fact that nicotine-induc… Webb22 juni 2024 · This action plan presents the concrete actions needed to achieve the priorities of the EU Drugs Strategy, adopted in December 2024.
