Digoxin immune fab or digoxin-specific antibody is an antidote for overdose of digoxin. [3] It is made from immunoglobulin fragments from sheep that have already been immunized with a digoxin derivative, digoxindicarboxymethoxylamine (DDMA). Its brand names include Digibind (GlaxoSmithKline) and DigiFab (BTG plc).
The primary treatment of digoxin toxicity is digoxin immune fab, which is an antibody made up of anti-digoxin immunoglobulin fragments. This antidote has been shown to be highly effective in treating life-threatening signs of digoxin toxicity such as hyperkalemia, hemodynamic instability, and arrhythmias. [11] Fab dose can be determined by two ...
The mechanism of action for drugs such as Digibind and Digifab, used when adverse events occur with the use of digoxin, is that the FAB regions on the antibodies created against digoxin expedite the excretion of the drug into urine. Therefore, the amount of digoxin in the body decreases quickly as it gets excreted rapidly.
Digoxin Immune Fab is the antigen binding fragment of polyclonal antibodies raised to Digitalis derivative as a hapten bound to a protein and is used for the reversal of life-threatening digoxin or digitoxin toxicity. [1] [2] [3] Rho(D) immune globulin is made from pooled human plasma provided by Rh-negative donors with antibodies to the D antigen.

Electrolyte balance is vital, since patients with low cardiac glycoside levels can still die after adequate digoxin Fab antibody treatment if they have disturbed electrolyte levels. [18] Treatment of slow heart rate and heart rhythm irregularities may require intravenous isoprenaline or atropine. [19]
An unusual side effect of digoxin is a disturbance of color vision (mostly yellow and green) called xanthopsia. Vincent van Gogh's "Yellow Period" may have somehow been influenced by concurrent digitalis therapy. Other oculotoxic effects of digoxin include generalized blurry vision, as well as seeing a "halo" around each point of light.
Types of monoclonal antibodies with other structures than naturally occurring antibodies. The abbreviations in the column Type are as follows: mab: whole monoclonal antibody; Fab: fragment, antigen-binding (one arm) F(ab') 2: fragment, antigen-binding, including hinge region (both arms) Fab': fragment, antigen-binding, including hinge region ...
