Sodium Citrate and Citric Acid Oral Solution Description

Sodium Citrate and Citric Acid Oral Solution, USP is a stable and pleasant-tasting systemic alkalizer containing sodium citrate and citric acid in a sugar-free base. It is a non-particulate neutralizing buffer.
Sodium Citrate and Citric Acid Oral Solution, USP contains in each teaspoonful (5 mL):
SODIUM CITRATE Dihydrate 500 mg (0.34 Molar)
CITRIC ACID Monohydrate 334 mg (0.32 Molar)
Each mL contains 1 mEq sodium ion and is equivalent to 1 mEq bicarbonate (HCO 3).
INACTIVE INGREDIENTS: grape flavoring, purified water, sodium benzoate, sorbitol and sucralose.

Sodium Citrate and Citric Acid Oral Solution - Clinical Pharmacology

Sodium citrate is absorbed and metabolized to sodium bicarbonate, thus acting as a systemic alkalizer. The effects are essentially those of chlorides before absorption and those of bicarbonates subsequently. Oxidation is virtually complete so that less than 5% of sodium citrate is excreted in the urine unchanged.

Indications and Usage for Sodium Citrate and Citric Acid Oral Solution

Sodium citrate and citric acid oral solution, USP is an effective alkalinizing agent. It is useful in those conditions where long-term maintenance of an alkaline urine is desirable, and is of value in the alleviation of chronic metabolic acidosis, such as results from chronic renal insuffi ciency or the syndrome of renal tubular acidosis, especially when the administration of potassium salts is undesirable or contraindicated. This product is also useful for buff ering and neutralizing gastric hydrochloric acid quickly and effectively.
Sodium citrate and citric acid oral solution is concentrated, and when administered after meals and before bedtime, allows one to maintain an alkaline urinary pH around the clock, usually without the necessity of a 2 A.M. dose. This product alkalinizes the urine without producing a systemic alkalosis in the recommended dosage. This product is highly palatable, pleasant tasting, and tolerable, even when administered for long periods.

Contraindications

Patients on sodium-restricted diets or with severe renal impairment.

Precautions

Sodium citrate and citric acid oral solution should be used with caution by patients with low urinary output unless under the supervision of a physician. This product should not be administered concurrently with aluminum-based antacids. Patients should be directed to dilute adequately with water and preferably, to take each dose after meals to avoid saline laxative effect. Sodium salts should be used cautiously in patients with cardiac failure, hypertension, impaired renal function, peripheral and pulmonary edema, and toxemia of pregnancy. Periodic examinations and determinations of serum electrolytes, particularly serum bicarbonate level, should be carried out in those patients with renal disease in order to avoid these complications.

Adverse Reactions/Side Effects

Sodium citrate and citric acid oral solution is generally well tolerated, without any unpleasant side effects, when given in recommended doses to patients with normal renal function and urinary output. However, as with any alkalinizing agent, caution must be used in certain patients with abnormal renal mechanisms to avoid development of alkalosis, especially in the presence of hypocalcemia.
