Embodiment 1

[0070] Example 1 Preparation of Solution Triamcinolone Acetate Injection

[0071] The prescription composition of the solution type triamcinolone acetonide acetate injection is composed of 1 mol of triamcinolone acetonide acetate, 1 mol of sulfobutyl ether-β-cyclodextrin, 10 mol parts by weight of sodium hyaluronate and 4750 ml of water for injection.

[0072] Add 1mol of sulfobutyl ether-β-cyclodextrin and 1mol of triamcinolone acetonide acetate to 1L of 75%~100% ethanol, stir and dissolve until clear, and evaporate the organic solvent in a vacuum rotary evaporation; then add 2.5L of 4mol / L sodium hyaluronate aqueous solution, dissolved until clear, then add 2250ml sterile water for injection, stir evenly, adjust the pH to 5.5, filter and sterilize to prepare sulfobutyl ether-β-cyclodextrin inclusion compound Injection.

Embodiment 2

[0073] Example 2 Preparation of Solution Triamcinolone Acetate Injection

[0074] The prescription composition of the solution-type triamcinolone acetonide acetate injection is composed of 1 mol triamcinolone acetonide acetate, 20 mol sulfobutyl ether-β-cyclodextrin, 1 mol weight part of sodium hyaluronate and 19040 ml of water for injection.

[0075] Add 20mol of sulfobutyl ether-β-cyclodextrin and 1mol of triamcinolone acetonide to 20L of 75%~100% acetonitrile, stir and dissolve until clear, and evaporate the organic solvent in a vacuum; then add 10L of 0.1 mol / L aqueous solution of sodium hyaluronate, dissolved until clear, then add 9040ml sterilized water for injection, stir evenly, and adjust the pH to 4.5. After filtering and sterilizing, an injection solution containing sulfobutyl ether-β-cyclodextrin inclusion compound is prepared.

Abstract

The invention provides a medical product containing solution-type triamcinolone acetonide acetate. The medical product contains triamcinolone acetonide acetate, sulfobutyl ether-beta-cyclodextrin and sodium hyaluronate. The medical product containing solution-type triamcinolone acetonide acetate is small in local irritation in clinic use, especially when the medical product is applied to intra-articular injection, the product is easy to absorb, the particle deposition on the surface of the periosteum existing in the suspension type triamcinolone acetonide acetate medical product is avoided, and the periosteum injury caused by particle deposition is reduced.

Description

technical field [0001] The invention relates to medical products, in particular to a medical product containing solution-type triamcinolone acetonide acetate. Background technique [0002] Triamcinolone acetonide is a long-acting glucocorticoid drug with strong and lasting anti-inflammatory and anti-allergic effects; it is suitable for various skin diseases, allergic rhinitis, arthralgia, bronchial asthma, frozen shoulder, tenosynovitis, slippery Meningitis, acute sprain, rheumatoid arthritis, etc.; because of its remarkable curative effect, the scope of clinical application continues to expand. Currently, the commercially available aqueous injections are triamcinolone acetonide acetate injection and triamcinolone acetonide injection, both of which have low water solubility and are suspension injections, using carboxymethylcellulose sodium as the suspending agent. When used, it is injected into the muscle, subcutaneous or joint cavity; its process and product quality proble...
