The study of the stability of silver proteinate solutions prepared in pharmacies
Today, medicines made in pharmacies are increasingly attracting consumers' attention and are in growing demand in Ukraine. Pharmacy production faces a number of problems, including the study of the stability of extemporaneous dosage forms and the determination of an optimal shelf life. 1 % and 2 % water silver proteinate solutions used in ophthalmology, otolaryngology and nephrology are produced in Ukrainian pharmacies both extemporaneously and as a reserve.
The aim. The aim of the work is to develop methods for quality support and study the chemical stability of 1 % and 2 % water solutions of silver proteinate, and to study the microbiological purity to extend the storage time of nasal drops.
Materials and methods. A study of the chemical stability of 1 % and 2 % water silver proteinate solutions of pharmaceutical production is carried out using chemical identification reactions (to silver and protein), quantitative determination by thiocyanatometric titrimetric method and determination of microbiological purity.
