Antipyrine was one of the first synthetic analgesics, derivatives of pyrazolone, which were used in medicine (1884). With the receipt of other analgesics, they began to use it relatively rarely. It does not currently have widespread use. However, he did not completely lose the value and remained in the nomenclature of medicines.

Like other pyrazolone derivatives, antipyrine has an analgesic, antipyretic and, to some extent, anti-inflammatory effect. In terms of analgesic and antipyretic activity, drugs of this group are close to salicylic acid derivatives. Derivatives of pyrazolone reduce the permeability of capillaries and prevent the development of an inflammatory reaction. The mechanism of this action is not clear. These compounds do not affect the pituitary - adrenal gland system.

The most active anti-inflammatory drug of this group - butadione - relatively strongly inhibits prostaglandin biosynthesis. He is assigned to the group of non-steroidal anti-inflammatory drugs.

Antipyrine has a moderate analgesic, antipyretic and anti-inflammatory effect. When applied topically, there is some hemostatic effect.

Antipyrine is used for neuralgia, colds.
