The soundness, stabilization and degradation process of lyophilized sodium prasterone sulfate (DHA • S) ended up examined and it had been assumed that among the list of degradation products was a strongly acidic compound, Potentially sodium bisulfate, which was fashioned via the hydrolysis of DHA •S.

Lyophilization, also known as freeze-drying, is a process utilized for preserving biological substance by eradicating the water from your sample, which entails 1st freezing the sample and after that drying it, beneath a vacuum, at very small temperatures. Lyophilized samples might be stored for much longer than untreated samples.

Exclusively, very best tactics for batch size dedication ended up discussed, including the effect of batch measurement on drying time, mindful variety of process parameters to stay away from products failure also to aid lyophilization of the most batch measurement as being a worst-case circumstance. Also, batch dimensions overage to compensate for losses for the duration of production ended up regarded.
