Gentamicin is one of the most commonly prescribed antibiotics in the aminoglycoside class of drugs. This is largely due to its spectrum of action, low cost, and affordability. It is both effective against gram-positive and gram-negative organisms. Gentamicin has no oral absorption, so there are no oral dosage forms. There are various commercial products on the market that contain gentamicin in the form of solutions for intramuscular and intravenous administration, eye dosage forms, as well as those for external applications. For the purposes of the present study, by using a UV-VIS spectrophotometer, we have determined the content of gentamicin in an injectable dosage form at a concentration of 40 mg/mL in ampoules with an expiration date of 2016 or 2017.
