Влияние добавок консервантов и витаминов на температуру плавления основы мягких лекарственных форм

Влияние добавок консервантов и витаминов на температуру плавления основы мягких лекарственных форм

Abstract

Дана количественная оценка влияния вспомогательных веществ – консервантов и витаминов – на температуру плавления смесей, используемых в качестве основ для изготовления мягких лекарственных форм. Установлено, что синтетические основы из полиэтиленгликолей и низкомолекулярного полиэтилена наряду с химической инертностью, способностью инкорпорировать гидрофильные и гидрофобные вещества, достаточной адгезией к коже и слизистым оболочкам демонстрируют устойчивую температуру плавления независимо от добавок консервантов (нипагина и сорбиновой кислоты) и витаминов С и Е. Традиционные липофильные основы из масла какао, парафина и пчелиного воска не чувствительны по температуре плавления к добавкам консервантов и чувствительны к добавкам витаминов С и Е. Экспериментально зафиксировано снижение температуры плавления основ на 12–14 градусов при добавлении витаминов в концентрациях, используемых в лекарственных формах.

A quantitative assessment of the impact of auxiliary substances – preservatives and vitamins – the temperature of melting mixtures used as a basis for making soft dosage forms is given. Synthetic basis of the polyethylene glycols and low molecular weight polyethylene exhibit chemical inertness, ability to incorporate hydrophilic and hydrophobic substances, sufficient adhesion to the skin and mucous membranes and a stable melting point irrespective additives preserving agents (nipagin and sorbic acid), and vitamins C and E. Melting temperature traditional lipophilic bases with cocoa butter, beeswax and paraffin is not sensitive to additives preserving agents and is sensitive to additives vitamins C and E. Experimentally registered decrease the melting temperature of bases at 12–14 degrees by adding vitamins in the concentrations used in the formulations.
