It acts as a buffer against acidosis by raising blood pH. Sodium Bicarbonate. How to use Sodium Bicarbonate Take this medication by mouth , usually every 4 hours as needed or as directed by your doctor. Absorption: Well absorbed orally Sodium bicarbonate is a white, crystalline powder that is commonly used as a pH buffering agent, an electrolyte replenisher, systemic alkalizer and in topical cleansing solutions. We studied the effects and possible mechanism of action of 1 M NaHCO3 on desipramine (DMI) toxicity in anesthetized, paralyzed rats. Onset: 15 min (IV) Duration: 1-2 hr (IV); 8-10 min (PO) Therapeutic range: 24-31 mEq/L. Acetazolamide. Sodium bicarbonate is a systemic alkalizer, which increases plasma bicarbonate, buffers excess hydrogen ion concentration, and raises blood pH, thereby reversing the clinical manifestations of acidosis. Pharmacokinetics. Sodium bicarbonate is a systemic alkalinizing agent which, when given intravenously, will increase plasma bicarbonate, buffer excess hydrogen ion concentration, raise blood pH and reverse the clinical manifestations of acidosis. Acetazolamide is a reversible inhibitor of the carbonic anhydrase enzyme that results in reduction of hydrogen ion secretion at the renal tubule and an increased renal excretion of sodium, potassium, bicarbonate, and water. Omeprazole; sodium bicarbonate products contain a significant amount of sodium and bicarbonate, which may aggravate other conditions (304 mg sodium / 13 mEq of sodium bicarbonate per capsule and 460 mg sodium / 20 mEq sodium bicarbonate per suspension packet). Mechanism of Action of Sodium Bicarbonate Sodium bicarbonate in water dissociates to sodium (Na+) and bicarbonate (HCO3 -) ions.
Sodium bicarbonate is the active ingredient in baking soda. Pentel P, Benowitz N. Alkalinization of the blood by administration of sodium bicarbonate or hyperventilation is widely recommended for treatment of cardiac toxicity due to tricyclic antidepressant overdose, yet its efficacy and mechanism of action are poorly defined. Sodium bicarbonate is an antacid that neutralizes stomach acid. For this purpose it is generally only used when the pH is less than 7.1 and when the underlying cause is either diarrhea, vomiting, or the kidneys. The carbonic acid then goes onto pick up hydrogen ions therefore decreasing the gastric pH. The potential mechanisms of sodium bicarbonate include high sodium load and the development of metabolic alkalosis with resultant decreased tissue penetration of the toxic substance with subsequent increased urinary excretion. Sodium bicarbonate may also be used for purposes not listed in this medication guide. Bicarbonate reacts with H+ ions to form water & carbon dioxide. sodium bicarbonate acts as a buffer by dissociating into sodium and carbonic acid. It may be used to treat the symptoms of stomach or duodenal ulcers. Identification Name Sodium bicarbonate Accession Number DB01390 Type Small Molecule Groups Approved Description. Mechanism of Action. Sodium bicarbonate is found in many OTC remedies for acid reflux.
The various uses and proposed mechanisms of action of sodium bicarbonate include: treatment of drug overdoses whereby the offending agent has sodium channel blocking properties; urinary and serum alkalinization to enhance the elimination of drugs by “ion trapping” and minimize drug distribution, respectively; Antacids: sodium bicarbonate and calcium carbonate PharmacoPhoto. Intravenous sodium bicarbonate, also known as sodium hydrogen carbonate, is a medication primarily used to treat severe metabolic acidosis. Tablets come in 325 milligram (mg) and 650 mg strengths. When used for this purpose, it is said to belong to the group of medicines called antacids. Mechanism of Action. Sodium (Na+) is the principal cation of the extracellular fluid and it maintains fluid and electrolyte disturbances.
