The product is derived and purified immunoglobulin fragments obtained from other domestic animals such as sheep previously immunized with Crotalus scutulatus/Mojave rattlesnake. 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.

Crotalus scutulatus antivenin
The product is indicated for the management of adult and pediatric patients with North American crotalid envenomation. The term crotalid is used to describe the Crotalinae subfamily (formerly known as Crotalidae) of venomous snakes which includes rattlesnakes, copperheads and cottonmouths/water moccasins.
Examples of Clinical Use:
Snake venom of rattlesnakes, copperheads and cottonmouths
Acts as an antivenin, relieving symptoms of envenomation from Crotalinae family of snakes, and preventing lethal consequences of snake evenomation.The Crotalidae family produces venoms which are generally necrolytic and hemolyzing to tissues. Hemorrhagins in crotalid venom is toxic to the blood vessels and therefore cause hemorrhage and edema at the wound site, in addition to systemic hemorrhage and shock. Significant anemia is observed due to hemolysis and extravasation of blood due to damaged vessels. Disseminated intravascular coagulation (DIC) has been observed in some cases. The most frequent initial clinical pathological changes include echinocytosis, thrombocytopenia, leukocytosis and prolonged activated clotting time. In general, edema and erythema along with fang marks (_Crotalidae _family) may be seen at the site of bite although it is tough to identify due to thick hair coat in animals.Patients sustaining rattlesnake envenomation often develop thrombocytopenia, the etiology of which is not clear. It has been shown thatCrotaline Fab antivenom improved platelet aggregation in an in vitro model of platelet dysfunction induced by venom from C. scutulatus.
Mechanism of action:
CROFAB is a venom-specific Fab fragment of immunoglobulin G (IgG) that works by binding and neutralizing venom toxins, facilitating their redistribution away from target tissues and their elimination from the body
