Abstract

The invention belongs to the technical field of medicine, and discloses a pranoprofen eye drop containing sulfobutyl ether-β-cyclodextrin, which comprises active ingredient pranoprofen, solubilizer sulfobutyl ether-β-cyclodextrin Essence, stabilizer, pH regulator, bacteriostatic agent and osmotic pressure regulator; The stabilizer is macromolecular polymer polyethylene glycol, polyvinyl alcohol, povidone, polyvinylpyrrolidone, sodium hyaluronate, povidone One of loxamer, hypromellose or a mixture thereof. The preparation method of the present invention is to dissolve SBE-β-CD in water for injection, add pranoprofen under heating at 60°C, and after it is completely dissolved, add other auxiliary materials in turn, stir until completely dissolved, and cool to room temperature. Adjust the pH value, add water for injection to the full amount, and filter through a 0.22 μm microporous membrane to obtain the product. The pranoprofen eye drops containing sulfobutyl ether-β-cyclodextrin reduces the irritation to the eyes during use, and significantly improves the stability of the pranoprofen eye drops.

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...
