Abstract

A medicine for treating psoriasis vulgaris contains clobetasol propionate and vitamin A acid. Its preparing process is also disclosed. Its advantages are high curativ effect, and low toxic by-effect.

Description

technical field [0001] The invention relates to a compound preparation and a preparation process thereof, in particular to a compound preparation comprising clobetasol propionate (CP) and tretinoin (RA) for treating psoriasis vulgaris and a preparation process thereof. Background technique [0002] Psoriasis is a common skin disease characterized by red papules or plaques covered with layers of silvery white scales. Currently, clobetasol propionate (CP) and retinoic acid (RA), which are routinely used clinically to treat psoriasis, are used alone. Clobetasol propionate (CP) is one of the most potent corticosteroids (CS) developed in the early 1970s, with vasoconstrictor activity and anti-inflammatory effects. Appropriate concentration of clobetasol propionate (CP) has the relatively optimal clinical curative effect, the strongest anti-inflammatory activity and the largest safety index. The mechanism of clobetasol propionate (CP) topical application involves inhibiting the ...
