Its analgesic effect is determined by the central and peripheral action of analgin included in the drug. Analgin, on the one hand, reduces inflammation and inhibits the formation of allogenic substances and, on the other, it stimulates the non-opiate antinociceptive system by inhibiting the synthesis of prostaglandins. Spasmalgon has a certain antipyretic and antiphlogistic action. It suppresses the respiratory center and is distinguished by its very quick and long-lasting effect.
