Two-Phase Semisolid Hydrophilic Systems – Hydrocreams
Dvoufázové polotuhé hydrofilní systémy – hydrokrémy
Vyrobit kvalitní léčivý přípravek v podobě hydrokrému je problematika velmi široká a komplikovaná.Hydrokrémy jako emulze typu o/v tvoří strukturovaný systém, který se skládá nejméně ze třífází, a to dispergované, krystalické hydratované a krystalické gelové. Zátěžové operace výrobníchpostupů mohou negativně působit jak na jednotlivé složky, tak na složitou strukturu hydrokrému.Proto musí být věnována patřičná pozornost formulační studii, která spolu s výrobními podmínkamizajistí produkci léčivého přípravku s požadovanými jakostními ukazateli.
Klíčová slova:

Overview
Production of a drug of good quality in the form of a hydrocream presents a wide set of complexproblems. Hydrocreams as emulsions of the o/w type form a structured system which consists of atleast three phases, the dispersed, crystalline hydrated, and crystalline gel one. The loading operationsof manufacturing procedures can negatively affect both the individual components and thecomplex structure of the hydrocream. Due attention must thus be paid to the formulation studywhich togetherwith the conditions ofmanufacture will ensure the production of a drug with requiredquality indices.
Key words:
