Antipyrine, aminopyrine, metamizole and other tablets are the phase-out drugs announced by the Ministry of Health in September 1982. Antipyrine is an analytical reagent. For the analysis of nitric acid, nitrous acid and iodine, used to determine the formation of complex cation elements, gravimetric determination of titanium.
