B Schulz et al.
Die Pharmazie, 41(2), 118-120 (1986-02-01)
The diffusion of 3-methylpyrazole through a synthetic polymer matrix and the effect of the solubility of the bioactive agent in polymers on the release behaviour of polymer combinations were studied. With increasing hydrophilicity of the polymer both the diffusion and

We tested the hypothesis that the gastrotoxicity of ethanol and other damaging agents is influenced through the modulation of alcohol dehydrogenase (ADH) by using either the ADH-inhibitor pyrazole or the noninhibitor derivatives of pyrazole. In time course experiments, the protection

The release behaviour of the antimicrobially active 3(5)-methylpyrazole from matrix systems prepared from maleic anhydride copolymers as well as from copolymers of maleic esters and maleic amides was studied. Under alkaline conditions erosion is the predominant release mechanism compared to

Die Pharmazie, 40(8), 548-552 (1985-08-01)
The release of 3-methylpyrazole from monolithic polymer films into aqueous media has been studied. The diffusion of the active agent decreased with increasing of the content of acetate groups in reacetylated poly(vinyl alcohols) and with increasing of the ester lengths
