cefafour Uses, Dosage, Side Effects, Food Interaction and all others data.
cefafour Hydrochloride is a preparation of cefafour. It is a fourth generation broad-spectrum cephalosporin antibiotic. cefafour acts by inhibition of bacterial cell wall synthesis. It is highly resistant to hydrolysis by most beta-lactamases and exhibits rapid penetration into gram-negative bacterial cells.
cefafour has been shown to be active against most strains of the following microorganisms:
Gram-Positive Microorganisms:
Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Viridans group streptococci, Staphylococcus epidermidis, Staphylococcus saprophyticus, Staphylococcus hominis, Streptococcus agalactiae.
Gram-Negative Microorganisms:
Enterobacter, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Acinetobacter calcoaceticus, Citrobacter diversus, Citrobacter freundii, Enterobacter spp., Haemophilus influenzae (including beta-lactamase producing strains), Haemophilus parainfluenzae, Hafnia alvei, Klebsiella oxytoca, Moraxella catarrhalis (including beta-lactamase producing strains), Morganella morganii, Proteus vulgaris, Providencia rettgeri, Providencia stuartii, Serratia marcescens, Neisseria meningitidis.

Uses
cefafour Hydrochloride is used for the treatment of the following infections:
• Pneumonia (moderate to severe)
• Uncomplicated and Complicated Urinary Tract Infections (including pyelonephritis)
• Uncomplicated Skin and Skin Structure Infections
• Complicated Intra-abdominal Infections
• Empiric Therapy for Febrile Neutropenic Patients.
cefafour is also used to associated treatment for these conditions: Bacterial Infections, Complicated Intra-Abdominal Infections, Complicated Urinary Tract Infection, Febrile Neutropenia, Meningitis, Bacterial, Pyelonephritis, Severe Pneumonia, Uncomplicated Urinary Tract Infections, Moderate Pneumonia, Uncomplicated skin and subcutaneous tissue bacterial infections
How cefafour works
Cephalosporins are bactericidal and have the same mode of action as other beta-lactam antibiotics (such as penicillins). Cephalosporins disrupt the synthesis of the peptidoglycan layer of bacterial cell walls. The peptidoglycan layer is important for cell wall structural integrity, especially in Gram-positive organisms. The final transpeptidation step in the synthesis of the peptidoglycan is facilitated by transpeptidases known as penicillin binding proteins (PBPs).

Impaired Hepatic Function - No adjustment is necessary for patients with impaired hepatic function.
Impaired Renal Function - In patients with impaired renal function (creatinine clearance <60 ml/min), the dose of cefafour should be adjusted. The recommended initial dose of cefafour should be the same as in patients with normal renal function except in patients undergoing hemodialysis. The recommended doses of cefafour in patients with renal insufficiency are presented in the following table:

Preparation of Solutions of cefafour Hydrochloride
Single-dose vial Administration Amount of diluent to be added
500 mg IM 1.3 ml
500 mg IV 5 ml
1 gm IM 2.4 ml

These solutions may be stored up to 24 hours at room temperature or 7 days in a refrigerator.
cefafour Hydrochloride is compatible at concentrations between 1 and 40 mg/ml with the following IV infusion fluids: (1) 0.9% Sodium chloride, (2) 5% and 10% Dextrose.
IV infusion: Add 5 mL, 10 mL, or 10 mL of a compatible IV soln to a vial labeled as containing 500 mg, 1 g, or 2 g, respectively, to provide soln containing approx 100 mg/mL, 100 mg/mL, or 160 mg/mL of the drug, respectively. The appropriate dose of the drug should then be added to a compatible IV soln.
IM inj: Add 1.3 mL or 2.4 mL of an appropriate diluent (e.g. sterile water for inj, NaCl 0.9%) to a vial labeled as containing 500 mg or 1 g respectively, to provide a soln containing approx 280 mg/mL.
Side Effects
Generally cefafour is well tolerated. However, few side-effects including rash, pruritus, urticaria, fever, headache, nausea, vomiting, diarrhea, dizziness, oral moniliasis may occur.
Toxicity
Symptoms of overdose include seizures, encephalopathy, and neuromuscular excitability.
Precaution
In patients with impaired renal function (creatinine clearance <60 ml/min), the dose of cefafour should be adjusted. cefafour should be prescribed with caution in individuals with a history of gastrointestinal diseases, particularly colitis.
Interaction
Increased potential for nephrotoxicity and ototoxicity of aminoglycosides. Increased risk of nephrotoxicity with potent diuretics (e.g. furosemide).

Volume of Distribution
- 18.0 ±2.0 L
- 0.3 ±0.1 L/kg [Pediatric]
Elimination Route
The absolute bioavailability of cefepime after an IM dose of 50 mg/kg was 82.3 (±15)% in eight patients.
Half Life
2.0 (± 0.3) hours in normal patients. The average half-life in patients requiring hemodialysis was 13.5 (± 2.7) hours and in patients requiring continuous peritoneal dialysis was 19.0 (± 2.0) hours.
Clearance
- 120 mL/min [Healthy adult male receiving a single 30-minute IV infusions of cefepime]
- 3.3 +/-1.0 mL/min/kg [Petriatic patients (2 months – 11 years of age) receiving a single IV dose]
Elimination Route
Elimination of cefepime is principally via renal excretion with an average (±SD) half-life of 2 (±0.3) hours and total body clearance of 120 (±8) mL/min in healthy volunteers. cefafour is excreted in human milk.
Pregnancy & Breastfeeding use
Pregnancy: There are no adequate and well-controlled studies of cefafour use in pregnant women. cefafour should be used during pregnancy only if clearly needed.
Lactation: cefafour is excreted in human breast milk in very low concentrations. Caution should be exercised when cefafour is administered to a nursing woman.
Contraindication
Hypersensitivity to cefepime or other cephalosporins.
Acute Overdose
Patients who receive an overdose should be carefully observed and given supportive treatment. Symptoms of overdose include encephalopathy (disturbance of consciousness including confusion, hallucinations, stupor, and coma), myoclonus, seizures, and neuromuscular excitability.
Interaction with other Medicine
Renal function should be monitored carefully if high doses of aminoglycosides are to be administered with cefafour because of the increased potential of nephrotoxicity and ototoxicity of aminoglycoside antibiotics. Nephrotoxicity has been reported following concomitant administration of other cephalosporins with potent diuretics such as furosemide.
Storage Condition
cefafour Hydrochloride should be stored in a cool & dry place and protected from light.
