Pharmacological properties.

Pharmacodynamics.

The active ingredient of the ointment is the venom of the common viper (Venenum viperae berus), which contains phospholipase, phosphodiesterase, hyaluronidase, and other active substances. Viper venom also contains specific action peptides that cause hemolysis, increase capillary permeability, and affect blood coagulation. When applied locally, viper venom exerts an irritant and analgesic effect.

Other active ingredients of the ointment, by stimulating sensitive nerve endings, produce a local irritant and analgesic effect. In addition to the analgesic effect, camphor, salicylic acid, and turpentine oil possess antiseptic properties, while salicylic acid also has a keratolytic effect.

Pharmacokinetics.

The ointment is rapidly absorbed, and within a few minutes a burning sensation, mild skin hyperemia, and a feeling of warmth develop. Analgesic effect begins within 20–30 minutes and lasts for 1.5–2 hours.
