藥理作用 :
1.治療代謝性酸中毒,本品能使血漿內碳酸氫根濃度升高,中和氫離子,從而糾正酸中毒。
2.鹼化尿液,應用本品時,由於尿中碳酸氫根濃度升高,尿液pH升高,使尿酸、磺胺類藥及血紅蛋白等不易在尿中形成結晶或聚集。
3.制酸,口服能迅速中和或緩衝胃酸,而不直接影響胃酸分泌。因而胃內pH迅速升高,緩解高胃酸引起的症狀。

適應症:
代謝性酸中毒之鹼化劑。
用法用量:
通常成人1次0.5-1.5錠,1日服用1-4次,飯後1小時及睡前或需要時服用,小兒劑量視年齡酌減。
副作用:
1.胃脹、胃腸堆氣。
2.腎功能患者,大劑量投予本品時,可能會造成代謝性鹼中毒。
藥物動力學:
1. Absorption
A) Bioavailability
1) Oral sodium bicarbonate results in gastric acid neutralization and carbon dioxide production. Sodium and excess bicarbonate are absorbed into the plasma (Reynolds, 1990).
2. Metabolism
A) Metabolism Sites and Kinetics
1) STOMACH
a) In the presence of stomach acid, bicarbonate ion forms carbon dioxide and water.
3. Excretion
A) Kidney
1) Plasma concentrations of bicarbonate are regulated by the kidney. In a normal healthy adult nearly all the glomerular filtered bicarbonate ion is reabsorbed with less than 1% excreted in the kidney. The excess bicarbonate, excreted in the urine along with sodium ions, causes the urine to become alkaline and has a diuretic effect (Reynolds, 1990).

交互作用:
Amphetamine, dextroamphetamine, ephedrine, flecainide, mecamylamine, methamphetamine, pseudoephedrine, quinidine
Sodium bicarbonate can decrease elimination of these drugs, thus increasing their therapeutic effects.
Chlorpropamide, lithium, methotrexate, salicylates, tetracyclines
Sodium bicarbonate can increase elimination of these drugs, thus decreasing their therapeutic effect.
Ketoconazole
PO sodium bicarbonate may decrease the dissolution of ketoconazole in the GI tract, reducing the effectiveness.
禁忌:
有高血壓、心臟病、腎疾患、腹水、水腫之患者禁止使用本劑。
注意事項:
1.肝功能不全、腎功能不全、心臟疾病、懷孕及限制食鹽之患者、老年人等應避免長期使用。
2.補充鈉會增高血壓,造成體液滯留及肺水腫的風險,故過度鹼化會惡化病情。
