Abstract

The invention discloses a turbid liquor eye composition with chlotiponuo and jiatishaxing and making method, which comprises the following parts: (a) 0. 2-2% chlotiponuo and salt with grain size below 50um, (b) 0. 2-1% jiatishaxing and salt, (c) 0. 5-2. 5% one or more non-ion polymer as suspension-assisting agent, (d) eye excipient agent. The making method comprises the following steps: grinding the chlotiponuo carbonate below 50um; sterilizing; adding jiatishaxing, non-ion polymer and other eye adjuvants to form an eye agent to treat and prevent opthalmitis and bacterial infection.

Description

technical field [0001] The invention belongs to the technical field of medicine and health, and relates to an ophthalmic composition and a preparation method thereof, in particular to an ophthalmic composition containing gatifloxacin and loteprednol etabonate for the treatment and prevention of eye inflammation and eye infection Compositions and methods of making them. Background technique [0002] Loteprednol etabonate is a new type of glucocorticoid drug, which has an obvious effect on reducing eye redness and swelling, and has a significant effect on various eye inflammations and seasonal allergic conjunctivitis, and has no intraocular Adverse reactions to increased blood pressure.
