in monoanionic form (second pKaof salicylic acid, phenol type, is up to 13.8 and it is not dissociated). The method has good selectivity, linearity in the usual dose concentration range (R2>0.99) and precision (RSD <6%). The limits of detection are under 6μmol/L for the four ...
the incidence of adverse reactions was lower than that in the control group and the difference was statistically significant(P<0.05).Conclusion:Metoprolol succinic acid sustained release tablets combined with trimetazidine in the treatment of gastrointestinal tumors with angina pectoris can improve the ...
However, the higher acidity of OSA-based FFSs could be explained by the presence of acid anhydride residues. In the case of all FFSs, the pH value was reduced after the incorporation of AST. The wetting properties of the solid surface can be identified by analysis of the value of the CA...
