Pharmaceutical composition for use in medical and veterinary ophthalmology
The invention relates to the manufacturing and use of pharmaceutical compositions of medicines (ophthalmic preparations) comprising a mitochondria-addressed antioxidant and a set of auxiliary substances providing effective treatment for ophtalmological diseases in humans and animals.
1. A pharmaceutical formulation for treatment or prophylaxis of eye pathology, comprising:
(a) from 1 nm to 25000 nm of a mitochondria-addressed antioxidant comprising:
(b) from 0.01% to 0.2% of a lipophilic, cationic concentration stabilizer that stabilizes a concentration of the mitochondria-addressed antioxidant by preventing reversible and irreversible absorption of the antioxidant to walls of a vial containing the pharmaceutical composition, the stabilizer comprising a benzalkonium salt, berberine, palmatine, tetraphenylphosphonium, tetrabutyl ammonium, or combinations thereof; and
(c) from 0.001% to 1% of a prolongator comprising a disaccharide, a trisaccharide, a polysaccharide, methylcellulose, hydroxyethylcellulose, hydroxypropyl-methylcellulose, carboxymethylcellulose, sodium chondroitin sulfate, sodium hyaluronate, carboxyvinyl polymer, polyvinyl ethanol, polyvinylpyrrolidone, macrogol, or combinations thereof.
2. The pharmaceutical formulation of claim 1 , wherein the mitochondria-addressed antioxidant is SkQ1-Br, SkQ1-C1, or SkQ1 2 -SO 4 .
3. The pharmaceutical formulation of claim 1 , further comprising a physiologically acceptable pH buffer comprising a phosphate buffer, an acetate buffer, a borate buffer, a carbonate buffer, a citrate buffer, a Tris buffer, a glutamine buffer, an epsilon-aminocaproic acid buffer, or combinations thereof.
4. The pharmaceutical formulation of claim claim 1 , wherein the water soluble cellulose derivative comprises methylcellulose, hydroxyethylcellulose, hydroxypropylmethylcellulose, carboxymethylcellulose, sodium chondroitin sulfate, sodium hyaluronate, or combinations thereof.
5. The pharmaceutical formulation of claim 1 , further comprising an isotonic component comprising sodium chloride, calcium chloride, glycerol, mannitol, sorbitol, boric acid, glucose, propylene glycol, or combinations thereof.
6. The pharmaceutical formulation of claim 1 , further comprising an active ingredient different than the mitochondria-addressed antioxidant, the additional active ingredient being an antioxidant, an antiseptic, an astringent, a cautery, a resorbent, a hyposensitizer, an anti-biotic, an anti-inflammatory preparation, an antibacterial, a sulfanilamide preparation, an antiviral preparation, a non-specific anti-inflammatory, a reparative preparation, a local anesthetic, a systemic ophthalmologic preparation, an anti-cataract preparation, a hypotensive anti-glaucoma medical preparation, a cholinomimetic preparation, an anticholinesterase preparation, a sympathomimetic, an adrenergic preparation, an antiadrenergic preparation, a beta-adrenergic blocker, a prostaglandin, a carbonic anhydrase inhibitor, a mydriatic, a vitamin, and a vitamin analog, a natural cornea moisture restorer, or combinations thereof.
7. The pharmaceutical formulation of claim 1 comprising, per 5 ml of solution:
about 770 ng SkQ1 bromide;
about 4.4 mg sodium dihydrophosphate;
about 4.7 mg sodium hydrogen phosphate dodecahydrate;
about 10 mg hydroxypropylmethylcellulose;
about 5 μg benzalkonium chloride;
about 45 mg sodium chloride; and
purified water to 5.0 ml.
8. The pharmaceutical formulation of claim 1 , wherein the lipophilic, cationic concentration stabilizer comprises benzalkonium chloride, benzethonium chloride, berberine, palmatine, tertraphenylphosphonium, tertrabutyl, ammonium, or combinations thereof.
