Ringer's lactate solution is in the crystalloid family of medications. [5] It is isotonic, i.e. it has the same tonicity as blood. [2] Ringer's solution was invented in the 1880s; lactate was added in the 1930s. [4] It is on the World Health Organization's List of Essential Medicines. [6] Lactated Ringer's is available as a generic medication. [1]

Ringer's solution is a solution of several salts dissolved in water for the purpose of creating an isotonic solution relative to the body fluids of an animal. Ringer's solution typically contains sodium chloride , potassium chloride , calcium chloride and sodium bicarbonate , with the last used to buffer the pH .
That immediately gets the drug's concentration in the body up to the therapeutically-useful level. First day: 1000 mg; the body clears 100 mg, leaving 900 mg. On the second day, the patient takes 100 mg, bringing the level back to 1000 mg; the body clears 100 mg overnight, still leaving 900 mg, and so forth.
Sodium lactate is the sodium salt of lactic acid, and has a mild saline taste. It is produced by fermentation of a sugar source, such as maize or beets , and then, by neutralizing the resulting lactic acid [ 4 ] to create a compound having the formula NaC 3 H 5 O 3 .
This is not to be confused with dose regimen, which is a type of drug therapy in which the dose [mg] of a drug is given at a regular dosing interval on a repetitive basis. Continuing the maintenance dose for about 4 to 5 half-lives (t 1/2 ) of the drug will approximate the steady state level. [ 1 ]
The level of digoxin for treatment is typically 0.5-2 ng/mL. [8] Since this is a narrow therapeutic index, digoxin overdose can happen. A serum digoxin concentration of 0.5-0.9 ng/mL among those with heart failure is associated with reduced heart failure deaths and hospitalizations. [9]
