Acute disseminated intravascular coagulation (DIC) is a life-threatening condition that may be encountered in many situations, especially in cases of shock with uncontrollable hemorrhage. Anisodamine, an alkaloid extracted from a Chinese herb, is well known for its dramatic therapeutic effect on DIC. Sixty male rabbits were used to establish an acute DIC model. A total of 240 blood samples were taken for laboratory assays of changes in blood coagulation factors, platelet count, platelet adhesion, platelet aggregation, malondialdehyde (MDA), thromboxane B2 (TXB2), and 6-keto-prostaglandin F1 alpha (6-keto-PGF1 alpha). Changes of the microcirculatory status and the rate of the blood flow in the conjunctival capillaries of 60 rabbits were observed with WXS-II microcirculation microscope. Pathological sections of the lungs and kidneys were studied. Our investigation showed the presence of microthrombi in the microvasculature. After treatment with anisodamine, the prothrombin time stayed in the normal range, fibrinogen consumption was lessened, adenosine-diphosphate-induced platelet aggregation was inhibited, thromboxane B2 and malondialdehyde concentrations were significantly lower than in the control group, and the elevated quantity of 6-keto-PGF1 alpha was spared. We concluded that the anti-platelet-aggregating, microcirculation-facilitating, thromboxane-B2-inhibiting, malondialdehyde-inhibiting, and 6-keto-PGF1 alpha-sparing effects of anisodamine are the important mechanisms of its dramatic therapeutic effect on DIC.

Anisodamine is a natural alkaloid drug isolated from the plant Anisodus tanguticus growing in western China. The chemical structure and pharmacological action are just like the cholinergic receptor blocking agents atropine or scopolamine. The specific characteristic of the drug is being able to relieve the dangerous situation of microcirculatory failure, especially in case of DIC or renal failure. The prognosis of the patients will be quite good. Another characteristic of the drug is that no serious toxic reaction occurs even in successive doses given intravenously up to 500 mg a day. This is about fifty times greater than a common dose of 10 mg. Since we begin with the drug as a routine medication for the symptomatic treatment of renal failure, DIC bleeding, and microcirculatory failure, we should say that the specific antivenin and anisodamine are two treasure drugs for snakebites.
