Problems solved by technology

[0005] To improve the antibacterial effect of cream, you can use antibacterial agents with strong antibacterial effect, use different antibacterial agents or antibacterial agents in combination with antibacterial synergists (such as propylene glycol) and antioxidants (such as butyl hydroxytoluene, Butylated hydroxyanisole and EDTA), etc., but the bacteriostatic effect mainly depends on the bacteriostatic agent. If the bacteriostatic effect of the bacteriostatic agent is weak, the bacteriostatic effect can be improved by adding antibacterial synergists and antioxidants , the effect is generally poor

Abstract

The invention discloses compound dexamethasone acetate cream and a preparation method thereof. The cream contains a bacteriostatic agent accounting for 0.35-0.45% of the weight of the cream, and the bacteriostatic agent is a mixture of methylparaben and propyl hydroxybenzoate, or the bacteriostatic agent is ethylparaben. The compound dexamethasone acetate cream disclosed by the invention has strong bacteriostatic efficacy on candida albicans, aspergillus niger, escherichia coli, pseudomonas aeruginosa and staphylococcus aureus, the bacteriostatic efficacy meets the requirements of the 2015 edition Chinese pharmacopoeia, the defect that the existing compound dexamethasone acetate cream is insufficient in bacteriostatic efficacy is overcome, and the compound dexamethasone acetate cream is strong in stability, relatively low in skin allergenicity, and high in safety.

Description

technical field [0001] The invention belongs to the technical field of pharmacy, and more specifically, the invention relates to a compound dexamethasone acetate cream and a preparation method thereof, and a method for improving the antibacterial effect of the compound dexamethasone acetate cream. Background technique [0002] The active ingredients of the compound dexamethasone acetate cream are dexamethasone acetate, camphor and menthol, which are used to treat localized pruritus, neurodermatitis, contact dermatitis, seborrheic dermatitis and chronic eczema. It belongs to the oil-in-water cream and is a multi-dose skin medicine. It needs to be opened repeatedly during use. Therefore, in order to avoid harm to the user due to exogenous pollution, a certain amount of bacteriostatic agent needs to be added to prevent the preparation During normal storage or use, due to microbial contamination and reproduction, the drug will deteriorate and cause harm to the user. [0003] Th...
