Abstract

The invention belongs to the technical field of medicine, and discloses pranoprofen eye drops containing sulfobutyl ether-beta-cyclodextrin. The pranoprofen eye drops comprise active component pranoprofen, the solubilizer sulfobutyl ether-beta-cyclodextrin, a stabilizer, a pH conditioning agent, a bacteriostatic agent and an osmotic pressure conditioning agent. The stabilizer is one or the mixture of a high-molecular polymer polyethylene glycol, polyving akohol, povidone, polyvinylpyrrolidone, sodium hyaluronate, poloxamer and hydroxypropyl methylcellulose. According to the preparation method, SBE-beta-CD is dissolved into water for injection to be heated at the temperature of 60 DEG C, the pranoprofen is added so as to be dissolved completely, the other auxiliary materials are added in sequence, stirring is performed until thorough dissolving, then, the mixture is cooled to the room temperature, the pH value is conditioned, water for injection is replenished, and the mixture is filtered through a 0.22-micrometer micropore filter membrane to obtain the pranoprofen eye drops. According to the pranoprofen eye drops containing the sulfobutyl ether-beta-cyclodextrin, using irritation to the eyes is lowered, and the stability is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of medicines, in particular to a pranoprofen eye drop and a preparation technology thereof, in particular to a pranoprofen eye drop containing sulfobutyl ether-β-cyclodextrin and a preparation method thereof. Background technique [0002] At present, the commonly used drugs for clinical treatment of various eye inflammation and allergic symptoms are antihistamines, anticongestants, corticosteroids, mast cell stabilizers and non-steroidal anti-inflammatory agents. Long-term use of antihistamines, anticongestants, corticosteroids, and mast cell stabilizers may lead to a decline in adrenal cortex function and induce serious adverse reactions. Non-steroidal anti-inflammatory drugs have no adverse reactions of corticosteroids, and have anti-inflammatory, analgesic and anti-allergic effects, so they are widely used in ophthalmology. [0003] Pranoprofen eye drops are the eye drops of propionate non-steroidal anti...
