Question: is aztreonam soluble in water?
Answer: It is freely soluble in water at 100 mg/ml. Aztreonam is categorized as a monobactam as it contains a single βlactam ring instead of the fused βlactam and thiazolidine rings found in generic β lactams. Due to its unique structure, Aztreonam is not typically inactivated by βlactamases.
