Vancomycin is marketed under several trade names, with the most prominent being Vancocin [1]. Other brand names under which vancomycin is sold include Lyphocin and Vancoled [1].
What is Vancomycin Used For?
Vancomycin is an antibiotic medication used to treat serious bacterial infections. It is particularly effective against Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) [2]. Common uses include treating complicated skin and soft tissue infections, bone and joint infections, pneumonia, endocarditis, and bacterial meningitis [2]. It is also a treatment for Clostridioides difficile infection (CDI), also known as C. diff [2].
How Does Vancomycin Work?
Vancomycin functions by inhibiting bacterial cell wall synthesis [3]. It binds to the D-alanyl-D-alanine termini of peptidoglycan precursors, which are essential components of the bacterial cell wall. This binding prevents the cross-linking of peptidoglycan strands, leading to a weakened cell wall and ultimately bacterial lysis [3].
What Are the Potential Side Effects of Vancomycin?
Common side effects associated with vancomycin treatment include flushing of the upper body, often referred to as "red man syndrome," nausea, and rash [4]. More serious, though less frequent, side effects can include kidney damage (nephrotoxicity), a decrease in white blood cells (neutropenia), and allergic reactions [4]. Hearing loss, which can be permanent, is another potential serious side effect, particularly with high doses or prolonged treatment [4].
What Are the Dosing Considerations for Vancomycin?
The dosage of vancomycin is typically based on a patient's weight and kidney function, as the drug is primarily eliminated by the kidneys [5]. Dosing adjustments are crucial to maintain therapeutic drug levels while minimizing the risk of toxicity [5]. Therapeutic drug monitoring, involving regular blood tests to measure vancomycin concentrations, is standard practice to ensure efficacy and safety [5].
When Does Vancomycin Patent Exclusivity Expire?
Vancomycin is an older antibiotic, and its original patents have long since expired. This means that generic versions of vancomycin have been available for many years, making it a widely accessible and affordable treatment option [6]. Information regarding the patent expiration of specific formulations or new uses of vancomycin can be found on DrugPatentWatch.com [7].
