A DPU that extracts prices of Spanish medicines from the web portal of Spanish Ministerio de Sanidad, Servicios Sociales e Igualdad. It visits the main page of their search portal (http://www.msssi.gob.es/profesionales/nomenclator.do) and specifies some non-restrictive search parameters (e.g., 1990-01-01). It then downloads the CSV file with the search results.
