Abstract

The present invention relates to a kind of ftibamzone eye drops. It contains the components of ftibamzone, osmotic pressure regulating agent, preservative, Tween 80, thickening agent, EDTA and sodium hydroxide.

Description

Technical field: [0001] The invention relates to a pharmaceutical preparation of phthalobutamol, in particular to a preparation of phthalobutamol eye drops. The preparation can be used for treating various trachoma; keratitis. Background technique: [0002] Phthalin, English name: Ftibamzone, chemical name is 3-phthalimido-2-oxobutyraldehyde-1,2-bisthiosemicarbazone and inclusion of dioxane. Molecular formula: C14H15N702S2 Molecular weight: 377.45 Phthalin is an antiviral drug. Has anti-Chlamydia trachomatis and anti-herpes virus activity. Its mechanism of action is mainly to inhibit viral DNA and early protein synthesis. Phthalidine cannot directly inhibit herpesvirus type II DNA polymerase, nor can it directly inactivate herpesviruses. Phthaltin has certain antifungal effect on dermatophytes. The aqueous solution of Phthalidin is usually unstable, especially in the environment of light and heat. The aqueous solution of phthalobutanol will degrade over time to produce...
