[Contribution to the stability of papaverine. Part 6: The stability of aqueous solutions of papaverine hydrochloride (author's transl)].
TLDR
It was found that solutions stored in glass vials degraded in a less degree than solutions kept in plastic vials. Expand
[The effect of the gas permeability of plastics on the stability of thiomersal. Part 49: Contributions to problems concerning the use of plastic receptacles for liquid pharmaceuticals (author's
TLDR
The mechanism of the degradation of Thiomersal in the presence of oxygen was elucidated and the ethylmercury resulting from this degradation is able to permeate through low-density polyethylene by which a displacement of the reaction equilibrium takes place in favour of the degrading products. Expand
[Analysis and stability of atropine sulfate and scopolamine hydrobromide. 3: Studies on the stability of tropane alkaloids; 80: contribution to problems in the use of plastic containers for liquid
TLDR
In the long-time test, it was found that unbuffered aqueous atropine sulphate solutions still contained 90% of their initial drug content after 18 months' storage in low-density polyethylene containers at 20 degrees C. Expand
[Analysis and stability of suxamethonium chloride. 1. Detection and quantitative determination of the intact active agent with its degradation products].
TLDR
Methods permitting to follow the course of degradation in injectable solutions of suxamethonium chloride, based on the spectrophotometric determination of the hydrolysis products succinic acid monocholine chloride and succinic Acid as a Cu-benzidine complex are developed. Expand
[Contribution to the stability of tropicamide solutions (author's transl)].
TLDR
Methods are described that permit (after thin-layer chromatographic repartition) to detect and to determine quantitatively the active principle in the presence of tropicamide solutions and its degradation products. Expand
