  • Anhydrous ampicillin stabilization and resultant compositions
    Patent number: 3993753
    Abstract: The formation of hydrates of anhydrous ampicillin in aqueous suspension may be retarded or entirely prevented for extended periods by (1) the addition of about 70 to 86% w/v of sucrose and (2) adjustment of the product pH to about 5.0 to 6.5. The invention is useful in extending the shelf life of aqueous dosage forms of anhydrous ampicillin.
