  • isobaric phase equilibria of the system 1 butanol water containinG Penicillin G Potassium salt at low pressures
    Fluid Phase Equilibria, 2003
    Co-Authors: Zhenghong Gao, Siping Wang, Qingchi Sun, Fengcai Zhang
    Abstract:

    Abstract The salt effect on the partially miscible system 1-butanol and water containinG Penicillin G Potassium salt was investiGated at low pressures usinG the ebulliometric method. The mean evaporation coefficient, f , of the small ebulliometer used was determined, and the reliability of the ebulliometric method was examined. Phase equilibrium data for the partially miscible system 1-butanol+water without salt and with different salt concentrations at 8.00, 5.33, and 2.67 kPa were measured with the ebulliometer. These data were used to calculate vapor–liquid equilibrium (VLE) compositions usinG the NRTL model and the modified NRTL model, respectively. vapor–liquid–liquid equilibrium (VLLE) compositions at certain pressure for the binary system without salt and with the salt were also calculated usinG the obtained NRTL parameters. Some of the results of the calculation were verified by experiments with a Glass equilibrium still and Gas chromatoGraphy analysis and showed Good aGreement. It was found that the salt effect of the Penicillin G Potassium salt on the 1-butanol+water binary system at low pressures causes the azeotropic temperature to rise sliGhtly and increases the mutual solubility of the two components. When the Penicillin G Potassium salt concentration reached 10 wt.%, the 1-butanol+water system becomes completely miscible.

    Abstract:

    Abstract Purpose To determine both the efficacy and safety of the topical application of 50 mG Penicillin G Potassium troches (Cankercillin™) in the treatment of minor recurrent aphthous stomatitis (RAS). Study desiGn The investiGation used a phase 2 double-blind, randomized placebo-controlled trial with a no-treatment arm. Subjects with minor aphthous ulcers of duration Results Thirty-one, 33, and 36 subjects were randomized to the active treatment, placebo, and no-treatment arms, respectively. Baseline findinGs were heteroGeneous across arms. Subjects who received Penicillin G treatment had complete ulcer healinG and pain relief siGnificantly earlier than those in the placebo and no-treatment arms. No allerGic reactions were observed. Conclusions Topical Penicillin G, by mechanisms which remain unclear, reduces the time of healinG and pain relief of minor aphthous ulcers with minimal safety concerns. LarGer phase 3 studies are necessary to confirm these findinGs.
