Ceftibuten: Drug Interaction

Note: Drug Interaction Categories:

  • Risk Factor C: Monitor When Using Combination
  • Risk Factor D: Consider Treatment Modification
  • Risk Factor X: Avoid Concomitant Use

Risk Factor C (Monitor therapy).

Aminoglycosides Third generation cephalosporins have the potential to exacerbate the nephrotoxic effects of aminoglycosides.
BCG Vaccine (Immunization) Antibiotics may lessen the benefits of the BCG vaccine (Immunization).
Lactobacillus & Estriol The therapeutic effects of Lactobacillus or Estriol can be diminished by antibiotics.
Probenecid May raise serum levels of cephalosporins.
Vitamin K antagonists (eg warfarin) The anticoagulant effects of Vitamin K antagonists can be enhanced by cephalosporins.

Risk Factor D (Consider therapy modifications)

 
Multivitamins/Minerals (with ADEK, Folate, Iron) Could reduce the serum concentration of ceftibuten. Ceftibuten absorption may be decreased by the zinc in multivitamins. Treatment: Take oral multivitamins containing zinc at least three hours after taking ceftibuten.
Multivitamins/Minerals (with AE, No Iron) Could reduce the serum concentration of ceftibuten. Ceftibuten absorption may be decreased by the zinc in multivitamins. Treatment: Take oral multivitamins containing zinc at least three hours after taking ceftibuten.
Sodium Picosulfate Antibiotics can reduce the therapeutic effects of Sodium Picosulfate. Patients who are currently using or have just finished using antibiotics should consider using an alternative product to cleanse the bowel before undergoing a colonoscopy.
Typhoid Vaccine The therapeutic effects of Typhoid vaccine may be diminished by antibiotics. The only affected strain is the live attenuated Ty21a. Patients being treated with systemic antibiotics should avoid vaccination with live attenuated Typhoid vaccine (Ty21a). This vaccine should not be used until at least three days after the cessation or discontinuation of antibacterial agent treatment.
Zinc Salts This may cause a decrease in serum Ceftibuten. Management: Oral zinc salts should be administered at least three hours after Ceftibuten. Exceptions: Zinc Chloride.

Risk Factor X (Avoid Combination)

 
BCG (Intravesical). The therapeutic effects of BCG (Intravesical) may be diminished by antibiotics
Cholera Vaccine Cholera Vaccine may be less effective if taken with antibiotics. Treatment: Cholera vaccine should be avoided in patients who have received systemic antibiotics.

 

Monitor:

  • Renal functions,
  • Hepatic functions, and
  • Blood CBC periodically with longer therapy.
  • After giving the patient the first dose of Cedax, keep an eye out for any anaphylactic symptoms.

How to take Cedax (Ceftibuten)?

  • Do not administer the pill with food.
  • The suspension should be administered at least two hours before or one hour after meals. Before using, shake the suspension.

Mechanism of action of Ceftibuten:

Cefotaxime blocks the formation of bacterial proteins, peptidoglycans and penicillin-binding proteins. This eventually leads to cell lysis through the use of autolytic enzymes. It is quickly absorbed and distributedIn the middle ear fluid, bronchial secretions and sputum. The drug accounts for 65%.Protein-boundWith abioavailabilitybetween 75% and 90%, and ahalf-life eliminationChildren: 2 hours, adults: 2.4 hours. Patients with blood pressures between 30 and 49 ml/min can be seen for a further 7.1 hours. Patients with CrCls between 5 and 29 ml/min will finish in 13.4 hours, whereas those with CrCls between 5 and 29 ml/min finish in 22.3 hours. Patients that need 22.3 hours had CrCls between 5 and 5 ml/min. In 2 to 2.6 hours, peak serum concentration can be obtained. 39% of the medication is eliminated through the faeces, whereas 56% is eliminated through the urine.
