Determination of biguanide groups in polyhexamethylene biguanide hydrochloride by titrimetric methods.
The biguanide concentration of polyhexamethylene biguanide hydrochloride (PHMB-HCl) was measured by non-aqueous titration with HClO4, argentometric titration, the Kjeldhal method, and colloidal titration. The summation value of non-aqueous titration and argentometric titration corresponded to two titrable nitrogens in five nitrogens per one unit of PHMB-HCl, and consisted with the result of the...
متن کاملBenefit of polyhexamethylene biguanide in Fusarium keratitis.
PURPOSE To report a series of 3 patients with soft contact lens-related Fusarium keratitis. Two of them were treated with the antiamoebic polyhexamethylene biguanide 0.02% (PHMB) in combination with antifungal drugs, and 1 patient was treated with PHMB as sole antifungal regimen. METHODS Chart review of 3 patients treated with PHMB in Fusarium keratitis. Two of them were refractory to the com...
متن کاملDetermination of polyhexamethylene biguanide hydrochloride using photometric colloidal titration with crystal violet as a color indicator.
A solution of polyhexamethylene biguanide hydrochloride (PHMB-HCl) was titrated with a standard solution of potassium poly(vinyl sulfate) (PVSK) using crystal violet (CV) as an photometric indicator cation. The end point was detected by a sharp absorbance change due to an abrupt decrease in the concentration of CV. A linear relationship between the concentration of PHMB-HCl and the end-point vo...
متن کاملEvaluating a dressing impregnated with polyhexamethylene biguanide
Aims: To evaluate a new polyhexamethylene biguanide (PHMB) foam dressing for inclusion in the specialist dressing section of a trust’s wound management formulary. Methods: KendallTM AMD (Covidien) antimicrobial foam dressing’s use was reviewed through a retrospective evaluation of patients who had been treated with the dressing. Data was collected from the medical and nursing notes of 25 patien...
