Paragraph 0025; 0038; 0040; 0041, (2017/07/19)
The invention relates to a sulbactam sodium preparation method belongs to the technical field of synthesis of beta-lactamase inhibitors. The sulbactam sodium preparation method comprises the steps that 6-amino penicillanic acid (6-APA) is used as a raw material, reacts in strong acid and a sodium nitrite water solution, then reacts under the effects of copper powder and hypophosphorous acid, and then a target product sulbactam sodium is prepared through oxidation and substitution reaction. The reaction process is simple in operation, the method includes few reaction steps, a by-product is reduced, the final reaction yield is high, the treatment difficulty and cost after wastewater production are reduced, the pressure of environmental protection is reduced for enterprises, the product production cost is reduced, and the sulbactam sodium preparation method is suitable for industrial production.
Ampicillin sodium and sulbactam sodium pharmaceutical composition
-
Paragraph 0054; 0055, (2016/11/17)
The present invention discloses an ampicillin sodium and sulbactam sodium pharmaceutical composition comprising sulbactam sodium and ampicillin sodium with the specific optical rotation of + 264 degrees to + 269 degrees, and the mass ratio of ampicillin sodium to sulbactam sodium is 2: 1. The ampicillin sodium and sulbactam sodium pharmaceutical composition is prepared from the sulbactam sodium and the ampicillin sodium with the particular specific optical rotation, the drug stability is improved, and drug safety is improved.
