Overview

Lower respiratory Tract Infection (LRTI) is one of the fourth most common cause of mortality across the globe, and constitutes to be a major portion in critically ill patients associated with prolonged hospitalisation. Apart from age factor, other risk factors which predispose to the LRTI include poor sanitization, severe malnutrition, and lack of breast feeding for infants, HIV infection, lack of immunization, chronic illness, family history of LRTI and exposure to tobacco smoke/air pollutants. The third generation cephalosporins are used in management and treatment of gram-negative and gram-positive organism. Common bacteria implicated in these infections include S. pneumoniae, H. influenzae, Chlamydia pneumoniae, and Staphylococcus aureus. Third generation cephalosporins also target respiratory ailments like acute bronchitis, pneumonia, acute exacerbation of chronic lung diseases (such as COPD or bronchiectasis).  Cefotaxime and ceftriaxone have been widely recommended in guidelines to be used for many infections and diseases, but, some serious adverse effects have been seen in past few years with ceftriaxone like cholelithiasis, encephalopathy, memory impairment, tonic- clonic seizures, neurotoxicity and auto-immune haemolytic anaemia. This fact compels us to revisit the clinically safer and efficacious drug Cefotaxime which have been used since decades but have not developed any resistance till date. Cefotaxime has been found to be well tolerated and not associated with hypo-prothrombinemia/coagulopathies, disulfiram-like reactions, as with other cephalosporins. It can readily cross the blood-brain barrier when administered intravenously and may treat gram-negative infections resistant to previous generations of cephalosporins. Cefotaxime, demonstrates good efficacy and safety in the management of LRTIs including CAP, hospital acquired/nosocomial acquired pneumonia, acute exacerbation of pneumonia and acute bronchitis caused by both gram positive as well as gram negative bacteria.
