🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionDisodium hydrogen citrate is rapidly absorbed from the gastrointestinal tract after oral administration.
DistributionCitrate and its metabolites distribute throughout the extracellular fluid and are taken up by cells, particularly in the liver and kidneys.
Protein BindingNot established from the available information.
MetabolismCitrate is metabolized in the liver via the Krebs cycle to bicarbonate and carbon dioxide.
Half-LifeThe half-life of citrate is approximately 30 minutes to 1 hour, but the effect on urine pH lasts longer.
ExcretionMetabolites are excreted primarily in the urine, with some carbon dioxide exhaled through the lungs.
BioavailabilityNot established from the available information.
Onset of ActionThe alkalinizing effect on urine typically begins within 1 to 2 hours after oral administration.
Peak Plasma TimePeak plasma levels of citrate are reached within 1 to 2 hours.
Duration of ActionThe effect on urine pH lasts for approximately 4 to 6 hours after a single dose.

How It Works

This medicine works by providing citrate ions that are metabolized to bicarbonate in the body. Bicarbonate acts as a buffer to neutralize excess acid, thereby increasing the pH of urine and blood. This alkalinization helps reduce the irritation caused by acidic urine on the bladder and urethra, and also inhibits the growth of certain bacteria. Additionally, it helps dissolve uric acid crystals, preventing stone formation.

Mechanism Steps

1
Absorption: Disodium hydrogen citrate is absorbed from the gastrointestinal tract after oral administration.
2
Metabolism: Citrate is metabolized in the liver to bicarbonate, which acts as a buffer.
3
Alkalinization: Bicarbonate neutralizes excess hydrogen ions, raising urine and blood pH.
4
Excretion: The excess bicarbonate and citrate are excreted primarily through the kidneys, alkalinizing the urine.
