Unasyn is a broad-spectrum antibiotic used to treat a wide range of bacterial infections. This medication is available in tablets containing ampicillin and sulbactam in a 375 mg strength, and is also available in vials of the same strength for injection. With sulbactam, ampicillin becomes more effective against bacteria previously resistant to it, expanding the drug's spectrum of action and making it a powerful option for combating many infections.
What are the ingredients in Unasyn?
Unasyn tablets and vials contain the following active ingredients:
Ampicillin.
Sulbactam.
Both have a total strength of 375 mg (the ampicillin to sulbactam ratio is usually 2:1, i.e., 250 mg ampicillin and 125 mg sulbactam in every 375 mg). In addition to these active ingredients, each dosage form contains inactive ingredients for the tablet or solution for injection.
