Spectrophotometric And Microbiological Determination Of The Stability Of Sodium Ampicillin As Affected By Ph, Enrico Frank Raffanti
Spectrophotometric And Microbiological Determination Of The Stability Of Sodium Ampicillin As Affected By Ph, Enrico Frank Raffanti
University of the Pacific Theses and Dissertations
The specific purpose of this investigation was to determine the effect of pH on the stability of ampicillin sodium for injection. Then, to correlate this information, a pH profile may be established to predict chemical stability with ampicillin sodium alone or when other drugs may be included in the admixture. With a pH profile the pharmacist could predict the length of time after which more than a 10 percent loss of activity would occur. Stability measurements were to be accomplished through a microbiological assay after adding ampicillin sodium to different buffer solutions. At the end of four hours, eight hours, …
