Pregnancy & Lactation
Pregnancy Category: C
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Increases blood and urinary pH by releasing a bicarbonate ion, which in turn neutralizes hydrogen ion concentrations
1g of sodium bicarbonate is equivalent to 11.9 mEq each of sodium and bicarbonate
Pharmacokinetics
8-10 min (PO); 1-2 hr (IV)
Excretion: Urine (<1%)
Onset of action: Rapid (PO); 15 min (IV)
