Ceftazidime is a broad-spectrum antibiotic used to treat various bacterial infections, including respiratory tract infections, urinary tract infections, and skin and soft tissue infections. As a third-generation cephalosporin, it exerts its antibacterial effect primarily by inhibiting the synthesis of bacterial cell walls.
Ceftazidime exhibits high stability against many β-lactamases. Among Gram-positive bacteria, it has certain antimicrobial activity against *Staphylococcus aureus*, *Streptococcus pyogenes*, and *Streptococcus pneumoniae*. Among Gram-negative bacteria, it is active against *Klebsiella* species, *Pseudomonas aeruginosa*, *Enterobacter*, and *Escherichia coli*. It can be used to treat conditions such as pharyngitis, tonsillitis, bronchitis, and cystitis.
However, patients with known hypersensitivity to cephalosporin antibiotics should not use ceftazidime. Some patients may experience side effects after taking the drug, such as rash, diarrhea, pruritus (skin itching), abdominal pain, nausea, and vomiting.
Patients are advised to take ceftazidime orally only under the guidance of a physician. Dosage should not be altered arbitrarily, as doing so may affect the drug's efficacy or lead to adverse effects, potentially delaying treatment.
