Amikacin is an aminoglycoside antibiotic used to treat severe gram-negative bacterial infections. It works by binding to the bacterial ribosome and inhibiting protein synthesis. Amikacin is prescribed for infections like pneumonia, bone/joint infections, bloodstream infections, and more. It is administered via intravenous or intramuscular injection and the dosage is based on the patient's condition, weight, and lab tests. Common side effects include nausea, vomiting, and pain at the injection site.
