Synonyms
Bacampicillin Hydrochloride; Carampicillin Hydrochloride

Pharmacological Index

Antibiotic, Penicillin


Use

Treatment of susceptible bacterial infections involving the urinary tract, skin structure, upper and lower respiratory tract; activity is identical to that of ampicillin


Pregnancy Risk Factor

B


Contraindications

Hypersensitivity to bacampicillin or any component or penicillins


Warnings/Precautions

Use with caution in patients allergic to cephalosporins; modify dosage in patients with renal impairment; high percentage of patients with infectious mononucleosis develop a rash during amoxicillin therapy


Adverse Reactions

1% to 10%: Gastrointestinal: Gastric upset, diarrhea, nausea

<1%: Rash, pseudomembranous colitis, agranulocytosis, mildly increased AST, hypersensitivity reactions


Overdosage/Toxicology

Signs and symptoms: Neuromuscular sensitivity, many beta-lactam containing antibiotics have the potential to cause neuromuscular hyperirritability or convulsive seizures

Treatment: Hemodialysis may be helpful to aid in the removal of the drug from the blood, otherwise most treatment is supportive or symptom directed


Drug Interactions

Decreased effect of oral contraceptives

Increased levels with probenecid; allopurinol theoretically has has an additive potential for amoxicillin/ampicillin rash


Stability

Reconstituted suspension is stable for 10 days when stored in the refrigerator


Mechanism of Action

Interferes with bacterial cell wall synthesis during active multiplication causing cell wall death and resultant bactericidal activity against susceptible bacteria


Pharmacodynamics/Kinetics

Protein binding: 15% to 25%

Metabolism: Hydrolyzed to ampicillin

Bioavailability: 80% to 98%

Half-life: 65 minutes, prolonged in patients with impaired renal function

Time to peak serum concentration: Area under the serum concentration time curve is 40% higher for bacampicillin than after equivalent ampicillin doses


Usual Dosage

Oral:

Children >25 kg and Adults: 400-800 mg every 12 hours

Dosing interval in renal impairment:

Clcr 10-30 mL/minute: Administer every 24 hours

Clcr <10 mL/minute: Administer every 36 hours


Dietary Considerations

May be administered with meals or on an empty stomach; may mix with milk, formula, or juice


Monitoring Parameters

Renal, hepatic, and hematologic function tests


Test Interactions

False-positive urine glucose with Clinitest®


Mental Health: Effects on Mental Status

Mental Health: Effects on Psychiatric Treatment

May produce agranulocytosis; use caution with clozapine and carbamazepine

Nursing Implications

Assess patient at beginning and throughout therapy for infection; observe for signs and symptoms of anaphylaxis


Dosage Forms

Powder for oral suspension, as hydrochloride: 125 mg/5 mL [chemically equivalent to ampicillin 87.5 mg per 5 mL] (70 mL)
