Abstract
The eye drops for treating xeroma, conjunctivitis, keratitis and keratohelcosis with high curative effect contains such active components as sodium hyaluronate, glucerine, complexon III, phosphoric acid buffer pair or boric acid buffer pair or hydrochloric acid or sodium hydroxide for regulating pH value to 5.0-7.5, sodium chloride for regulating osmotic pressure, antiseptic and distilled water.
Description
The invention belongs to field of pharmaceutical technology, is a kind of main treatment xerophthalmia, also can treat the eye drop of various oculopathy such as various conjunctivitis, keratitis, corneal ulcer.Xerophthalmia is a kind of climacteric patient and common complaint among the elderly, and infant is because monophagia causes vitamin A deficiency also xerophthalmia can occur.Xerophthalmia is the disease that causes because of tear, mucin secretion deficiency, and Most patients easily causes various oculopathy such as xerophthalmia keratitis and conjunctivitis, causes many miseries to the patient.At present, China's medical market does not have the medicine of specially controlling xerophthalmia as yet, generally only adopts oral medicines such as vitamin A, vitamin D to nurse one's health clinically, does not finally still reach the effect of treatment.And hyaluronic acid sodium (English: SodiumHyaluronate also claims hyaluronate sodium) has extremely strong moisture retention and lubricity, and external clinical data has proved the choice drug of this medicine for the treatment xerophthalmia.
In addition, treat the collyrium of oculopathy at present, owing to it can not rest in the eyelid long period, so therapeutic effect is not good enough.Though but the eye ointment long period rests in the eyelid,, block sight line, thereby be only limited to use in bed, bring inconvenience to the patient because of it is semi-solid thing.In the past, pharmaceutical industry improved the viscosity of medicinal liquid by the practice of adding thickening agent in eye drop, to reach was prolonged medicinal liquid time of staying in conjunctival sac, improved the purpose of drug effect, and the zest of eye drop is lowered.The customary thickeners of being added has methylcellulose, polyvinyl alcohol and polyvidon etc.Result of study in recent years shows that adopting natural mucopolysaccharide hyaluronic acid sodium is thickening agent, and the effect that is played is that above thickening agent is incomparable.Hyaluronic acid sodium is a macromolecule mucopolysaccharide that extracts in animal tissue or produce through bacterial fermentation, and by the regular macromole chain polysaccharide that repeats to constitute of disaccharide unit that D-glucuronic acid and N-acetylglucosamine ammonia constitute, molecular weight is 2.7~7.2 * 10
6Make it have unique character Deng the carboxyl on the glucuronic acid residue of space length, the most outstanding a bit is exactly the viscoelasticity that solution has height, and molecular weight is long more, and solution viscosity is high more.Be added to hyaluronic acid sodium in the eye drop and not only played the thickening effect of common thickening agent, and because the eye drop that hyaluronic acid sodium constituted is a non-Newtonian fluid, viscosity can descend rapidly with the increase of shearforce, thereby can not make the eye sensation difficult nictation, sticking slimy sensation is arranged, and this point be above-mentioned thickening agent institute inevitably.The more important thing is, external animal pharmacology and pharmacodynamics test studies show that, the animal corneal surface epithelial cell exists the hyaluronic acid sodium binding site, be after the eye drop of carrier enters ophthalmic with the hyaluronic acid sodium, combination by hyaluronic acid sodium and binding site, make medicinal liquid be stranded in the corneal epithelium surface for a long time, its effect that prolongs drug effect than with other thickening agent thickening, viscosity in addition up to the eye drop of tens of times of its viscosity can not reach.
Hyaluronic acid sodium is a macromolecular substances that chemical property is more stable, and is compatible with most drug, do not produce physical and chemical reaction.Existing many example proof hyaluronic acid sodiums can use with compatibilities such as most antibiotic, hormone, anti-inflammatory analgesics.
Purpose of the present invention: the eye drop that provides a kind of main treatment xerophthalmia, also can same antibiotic, hormone and other antimicrobial drug and remission medicine be made into compound preparation, constituting a series of is the eye drop series of carrier with the hyaluronic acid sodium, treat multiple oculopathy such as various conjunctivitis, keratitis, corneal ulcer, have that curative effect is strong, zest is little, and eye had extremely strong moistening and lubrication, the advantage of relief of symptoms simultaneously can be arranged; And provide the preparation method of this class eye drop.
