Problems solved by technology

Many existing technologies use preservatives to inhibit the growth of bacteria in atropine sulfate eye drops, but preservatives often cause eye allergy or irritation, and long-term use of patients may also damage corneal epithelial cells
The atropine sulfate eye drops in a single-dose package must be discarded if it is not used up on the same day, otherwise there will still be bacteria growth problems; Eye drop bottles with sterile air filtration function, but eye drops using the above two containers are usually more expensive, which is not conducive to popularization

Abstract

The invention discloses an ophthalmic pharmaceutical composition comprising 0.01-1 wt% of atropine sulfate, and the pH value of the ophthalmic pharmaceutical composition is 3.5-4.0; and the osmotic pressure is 180 to 300 mOsm / kg. The pharmaceutical composition can obviously improve the problem of related substances which is not easy to overcome in the prior art; and the composition is simple in component, is not easy to form agglomerates of micron order or above, and is beneficial to improving the corneal penetrability of atropine sulfate molecules.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical compositions, in particular to an ophthalmic pharmaceutical composition, in particular to an ophthalmic pharmaceutical composition for enhancing atropine sulfate corneal penetration and reducing the content of related substances. Background technique [0002] Atropine sulfate (atropine sulfate) belongs to ester drugs, and it is easy to decompose in aqueous solution to generate belladonna phenol (Tropine), tropic acid (TropicAcid), scopolamine (Scopolamine) and other related substances. Easy hydrolysis failure. When there is no element that can stabilize hydroxide ions in the aqueous solution, atropine sulfate is easily affected by the hydroxide ions, thus breaking bonds and degrading to form related substances such as belladonnaol and tropic acid ( figure 1 / path 1); Or, hydroxide ion is easy to produce bond with the chair structure of atropine sulfate, forms related substances such as 6-...
