“…As a result, liquid solid lipid dispersions possess a low viscosity (approximately 100 mPa s) and a yield value of practically zero [15]. Therefore, the liquid solid lipid dispersions usually have to be incorporated in convenient topical dosage forms like hydrogels or creams to obtain a topical application form having the desired semisolid consistency [21,24]. Incompatibilities with ingredients from the hydrogel or cream may occur due to interactions between the gel forming polymer, emulsifying agents, lipid and drug.…”

“…Esta cristalização ocorre principalmente com polímeros de maior energia (α,β'), e, conseqüentemente, mais instáveis. Sendo assim, durante a estocagem, estes lipídeos podem se reorganizar em formas de menor energia, mais estáveis e altamente organizadas (formas β), expulsando o fármaco que estava localizado nas imperfeições dos cristais (Figura 8) (Muller et al, 2002).…”
