Digoxin immune Fab used to treat digoxin toxicity. 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 ...
In toxicity, the usual supportive measures are provided. If arrhythmias prove troublesome, or malignant hyperkalaemia occurs (inexorably rising potassium level due to paralysis of the cell membrane-bound, ATPase -dependent Na/K pumps), the specific antidote is antidigoxin (antibody fragments against digoxin, trade names Digibind and Digifab). [ 7 ]
It is used for digoxin toxicity. Digoxin toxicity can emerge during long-term therapy as well as after an overdose. It can occur even when the serum digoxin concentration is within the therapeutic range when one of the following is present: [4] [5] Hemodynamically unstable arrhythmia; End organ damage; digoxin level > 4 ng/ml if chronic ingestion
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration. LD 50 figures are frequently used as a general indicator of a substance's acute toxicity. A lower LD 50 is indicative of higher toxicity. The term LD 50 is generally attributed to John William Trevan. [2]
Rare causes of hyperkalemia are discussed as follows. Acute digitalis overdose such as digoxin toxicity may cause hyperkalemia [22] through the inhibition of sodium-potassium-ATPase pump. [14] Massive blood transfusion can cause hyperkalemia in infants due to leakage of potassium out of the red blood cells during storage. [14]
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
Therapeutic drug monitoring (TDM) is a branch of clinical chemistry and clinical pharmacology that specializes in the measurement of medication levels in blood.Its main focus is on drugs with a narrow therapeutic range, i.e. drugs that can easily be under- or overdosed. [1]
