Peringatan Keamanan

Ed50 for the Crotolus scutulatus snake evenomation is 8 mg antivenin/mg venom FDA label.

Most common adverse reactions (incidence ?5% of subjects) were urticaria, rash nausea, pruritus and back pain. Hypersensitivity reactions may also occur FDA label.

Hypersensitivity reactions can occur to substances derived from sheep plasma; anaphylaxis and anaphylactoid reactions are possible, especially in patients with known allergies to sheep protein. Immediate treatment (including epinephrine 1 mg/mL) for anaphylaxis and/or hypersensitivity reactions must be available prior to administration. In cases of acute hypersensitivity reactions, including anaphylaxis and anaphylactoid reactions, discontinue infusion and institute appropriate emergency treatment. Sensitization may occur with repeated doses of antivenin L2859.

Drugs, such as crotalidae antivenin which are processed with papain, may lead to hypersensitivity reactions in patients allergic to papaya, other papaya extracts, papain, chymopapain, or the pineapple-enzyme bromelain. There may also be cross-allergenicity with dust mite and latex allergens L2859.

Late serum reactions (rash, pruritus, urticaria, or serum sickness consisting of severe rash and pruritus) reported in 12% (5/42) of patients in initial clinical trials have been observed and delayed hypersensitivity or serum sickness reported in 5–11% of patients in other studies L2859.

Crotalus scutulatus antivenin

DB13891

biotech approved experimental

Deskripsi

Crotalus scutulatus antivenin is derived and purified immunoglobulin fragments obtained from other domestic animals such as sheep previously immunized with Crotalus scutulatus (also known as the Mojave rattlesnake L2856).

The final purified antivenin product is obtained by mixing other different monospecific snake antivenins and isolating the antivenin of interest through fractionation and chromatography techniques. It is intravenously administered to limit systemic toxicity FDA label, L2857, L2858.

CROFAB (crotalidae polyvalent immune fab (ovine))is a sheep-derived antivenin used for the management of adult and pediatric patients with North American crotalid envenomation FDA label, which includes the Crotalus scutulatus snake (Mojave snake).

Mojave rattlesnakes inhabit desert areas of the southwestern United States and central Mexico. Specimens with type A venom, which cause a different pattern of injury than other rattlesnakes, have been reported in southern California, Nevada, Utah, Arizona, Texas, and New Mexico L2856.

Since it was approved by the Food and Drug Administration in October 2000, crotalidae poyvalent immune Fab (CroFab) has largely replaced previously used crotaline antivenom. CroFab is more specifically tailored for crotalids of North America and is less allergenic than whole immunoglobulin antivenoms L2861.
