🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionSodium bicarbonate is rapidly absorbed from the gastrointestinal tract after oral administration. The absorption is efficient, but the exact bioavailability is not well-defined because it is a simple compound that participates in normal physiological buffering. The onset of gastric neutralization is within minutes.
DistributionSodium bicarbonate distributes throughout the extracellular fluid compartment. It does not bind to plasma proteins and is freely filtered by the kidneys.
Protein BindingNot applicable. Sodium bicarbonate does not bind to plasma proteins.
MetabolismSodium bicarbonate is not metabolized in the traditional sense. It participates in acid-base balance and is converted to carbon dioxide and water in the process of neutralizing acid.
Half-LifeNot established from the available information. The elimination half-life is not a relevant pharmacokinetic parameter for this compound as it is rapidly equilibrated and excreted.
ExcretionSodium bicarbonate is excreted primarily by the kidneys. Unabsorbed portion is excreted in feces. The kidneys regulate bicarbonate excretion to maintain acid-base balance.
BioavailabilityNot established from the available information. As a simple salt, it is considered to be completely absorbed, but bioavailability as a drug parameter is not typically reported.
Onset of ActionThe onset of action for relief of indigestion is within 5 to 10 minutes after oral administration. For systemic alkalinization, the effect occurs within 15 to 30 minutes.
Peak Plasma TimeNot established from the available information. Peak plasma bicarbonate levels occur within 1 to 2 hours after oral ingestion.
Duration of ActionThe duration of gastric acid neutralization is relatively short, typically 30 to 60 minutes. Systemic alkalinization effects last for several hours, depending on renal function and dose.

How It Works

Sodium bicarbonate is a weak base that works by directly neutralizing hydrochloric acid in the stomach, forming sodium chloride, water, and carbon dioxide. This reaction reduces the acidity of gastric contents and relieves symptoms of indigestion. Systemically, when absorbed, it acts as an alkalinizing agent, increasing plasma bicarbonate levels and raising blood pH. In the kidneys, it increases urinary pH by excreting excess bicarbonate, which helps to dissolve uric acid stones and increases the elimination of acidic drugs like salicylates or phenobarbital.

Mechanism Steps

1
Gastric acid neutralization: Sodium bicarbonate reacts with hydrochloric acid in the stomach to form sodium chloride, water, and carbon dioxide, thereby reducing gastric acidity.
2
Systemic absorption: A portion of sodium bicarbonate is absorbed into the bloodstream from the gastrointestinal tract.
3
Buffering action: In the blood, bicarbonate ions act as a buffer, combining with excess hydrogen ions to form carbonic acid, which then dissociates into water and carbon dioxide, raising blood pH.
4
Renal excretion: The kidneys filter bicarbonate and excrete excess in urine, increasing urinary pH and promoting the elimination of acidic compounds.

💡 How to Take bisonate 500mg tablet

Strength: 500mg immediate-release tablet

1Take this medicine by mouth with a full glass of water.
2Swallow the tablet whole; do not crush or chew unless directed.
3Take it after meals or as directed by your doctor.
4Do not take more than the recommended dose.
5If you are taking other medicines, take them at least 1-2 hours apart from this medicine.

Dosage Information

Adult DosageThe usual adult dose for indigestion is 300 mg to 600 mg (or as directed) taken as needed, up to four times daily. For metabolic acidosis, the dose is individualized based on serum bicarbonate levels and clinical response, often ranging from 1 to 3 grams daily in divided doses. The maximum daily dose should not exceed 4 grams unless directed by a physician. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may be more sensitive to the effects of sodium bicarbonate, especially regarding sodium retention and electrolyte imbalances. Use with caution and monitor renal function and electrolytes. Dose should be individualized by a clinician.
Renal ImpairmentUse with caution in patients with renal impairment. Dose adjustment may be necessary based on creatinine clearance and serum bicarbonate levels. Consult a nephrologist for guidance.
Hepatic ImpairmentNo specific dosage adjustment is required for hepatic impairment, as sodium bicarbonate is not metabolized by the liver. However, monitor for electrolyte imbalances.
Maximum Daily DoseThe maximum daily dose for self-medication should not exceed 4 grams (4000 mg) in adults. Higher doses should only be used under medical supervision.
