Effective for gram-positive, gram-negative, anaerobic, and against multi-antibiotic resistant bacteria (such as Staphylococcus aureus [MRSA] and Acinetobacter baumannii), but not effective for Pseudomonas spp. and Proteus spp. Teeth discoloration and same side effects as tetracycline. Not to be given to children and pregnant or lactating women.
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas. P. aeruginosa is a germ found in the environment and it is an opportunistic human pathogen most commonly infecting immunocompromised patients, such as those with cancer , diabetes , cystic fibrosis , [ 1 ] severe burns, AIDS , [ 2 ] or people who ...
The extended-spectrum penicillins are a group of antibiotics that have the widest antibacterial spectrum of all penicillins. [1] Some sources identify them with antipseudomonal penicillins, [2] others consider these types to be distinct. [3] This group includes the carboxypenicillins and the ureidopenicillins.
Cefepime is a broad-spectrum cephalosporin antibiotic and has been used to treat bacteria responsible for causing pneumonia and infections of the skin and urinary tract. Some of these bacteria include Pseudomonas , Escherichia , and Streptococcus species.
Ertapenem is mainly eliminated via the kidneys and urine (80%) and to a minor extent via the faeces (10%). Of the 80% found in the urine, 38% is excreted as the parent drug and 37% as the ring-opened metabolite. The biological half-life is about 3.5 hours in women, 4.2 hours in men and 2.5 hours in children up to 12 years of age. [7] [13]
The activity of ceftazidime/avibactam against the important hospital pathogen Pseudomonas aeruginosa is variable, due to the potential presence of other resistance mechanisms in addition to β-lactamase production.
