Uruguayan Alejandro Zaffaroni is responsible for more than 40 Latin American inventions. Zaffaroni’s work mainly focused on drug administration, often through bandages. This method is called transdermal drug administration, meaning through the skin. He started patenting in the 1970s. Thanks to Zaffaroni, drugs now administered through the skin via patches or bandages include nicotine, antidepressants, and motion sickness.
