【Task】 In the present invention, an antibiotic compound composed of at least one β-lactam antibiotic and an ionic complex capable of suppressing the formation of at least one granule is disclosed. One β-lactamase inhibitor or buffer component can be added, or at least one β-lactamase inhibitor and buffer component can be added simultaneously, the compound can be prepared into a stable solution formulation, It is also possible to prepare a solution preparation in the same container as at least one aminoglycoside antibiotic to make it a drug that suppresses microbial infection. A buffer component is added at the same time to prepare a solution preparation, which can be used as an antimicrobial infection drug. [Selection figure] None |
