Cautions for Nizatidine

Contraindications

Warnings/Precautions

General Precautions

Gastric Malignancy

Response to nizatidine does not preclude presence of gastric malignancy.1

Respiratory Effects

Administration of H2-receptor antagonists has been associated with an increased risk for developing certain infections (e.g., community-acquired pneumonia).175

Specific Populations

Pregnancy

Category B.1 10

Self-medication in pregnant women: consult a clinician before using.1

Lactation

Distributed into milk.1 21 Discontinue nursing or the drug.1

Self-medication in nursing women: consult a clinician before using.b

Pediatric Use

Efficacy not established in children <12 years of age.1 126

Safety and efficacy for self-medication not established in children <12 years of age; do not use unless directed by a clinician.b

Geriatric Use

No substantial differences in safety and efficacy in those ≥65 years of age relative to younger adults, and dosage adjustment solely on the basis of age generally is not required.1 2 5

Possibility exists of greater sensitivity in some geriatric individuals.a

Substantially eliminated by the kidneys; because geriatric patients are more likely to have decreased renal function, use caution in dosage selection.a Monitoring of renal function may be useful.a In geriatric patients with renal impairment, modify dose and frequency of administration in response to the degree of renal impairment.1 2 (See Renal Impairment under Dosage and Administration).

Renal Impairment

Use with caution.1 Dosage adjustments necessary based on degree of renal impairment.1 (See Renal Impairment under Dosage and Administration).

Duration

Dose dependent.2 6 19

Nocturnal gastric acid secretion is inhibited for 10–12 hours after a single 300-mg dose.1 2 4 7 8

Inhibition of food-stimulated secretion generally persists for up to 4 hours following a 150- or 300-mg dose.1 2 20

Food

May slightly enhance bioavailability.1 2 4 5 6 9 12

Distribution

Extent

Not fully characterized.4

Nizatidine crosses the placenta5 26 and is distributed into milk.1 21

Plasma Protein Binding

35%, mainly to α1-acid glycoprotein.1 2 3 5 6 15

Elimination

Metabolism

Metabolized in the liver to active N-desmethylnizatidine (60% as active as nizatidine in blocking acid secretion), and inactive nizatidine N-oxide and nizatidine sulfoxide.1 2 5 15 22

Minimal first pass metabolism.1 2

Elimination Route

Excreted principally in urine1 2 3 15 (90%);1 5 6 15 about 60–65% is excreted unchanged,1 2 5 6 22 8% is excreted as N-desmethylnizatidine, 6% as nizatidine sulfoxide, 6% as nizatidine N-oxide, and about 15% as unidentified metabolites.1 2 5 6 15 <6% of a dose is eliminated in feces.1 2 5 6 15

Half-life

1–2 hours.1 2 3 4 5 6 9 12 16 22 23

Special Populations

In patients with renal impairment, half-life averages 2.1 hours when Clcr is 50–75 mL/minute, 4.1 hours when Clcr is 10–49 mL/minute, and ranges from 3.5–11 hours in anuric patients.1 2 3 5 6 22 23

Does not appear to be removed appreciably by hemodialysis.1 22 23
