Vancomycin is primarily effective against Gram-positive bacteria, including Staphylococcus aureus (including methicillin-resistant Staphylococcus aureus, or MRSA) and Streptococcus species [1][2]. It is also active against Enterococcus species, Clostridium difficile, and Listeria monocytogenes [2].
What bacteria is Vancomycin NOT effective against?
Vancomycin has no activity against Gram-negative bacteria [2].
How does Vancomycin work?
Vancomycin functions by inhibiting bacterial cell wall synthesis [1]. It binds to the D-alanyl-D-alanine termini of peptidoglycan precursors, preventing the cross-linking of these precursors and thus weakening the cell wall [1]. This ultimately leads to bacterial lysis and death [1].
What is Vancomycin used to treat?
Vancomycin is prescribed for serious infections caused by Gram-positive bacteria that are resistant to other antibiotics [1][2]. This includes conditions like MRSA infections, endocarditis, meningitis, osteomyelitis, and Clostridium difficile-associated diarrhea [1][2].
Are there different types of Vancomycin?
Vancomycin is available in intravenous (IV) and oral formulations. The IV form is used for systemic infections, while the oral form is typically used to treat Clostridium difficile infections in the gastrointestinal tract [1].
What are the side effects of Vancomycin?
Common side effects include infusion-related reactions such as flushing (red man syndrome), itching, and rash [1]. Other potential side effects can include kidney damage, changes in blood cell counts, and allergic reactions [1].
When does Vancomycin patent expire?
Information regarding specific patent expirations for Vancomycin is not readily available in the provided context. However, Vancomycin is a long-established antibiotic, and its original patents have long since expired, leading to its availability as a generic medication [3]. DrugPatentWatch.com tracks drug patent information and may offer details on patents related to its manufacturing or formulations [3].
