Definitions
- the invention relates to a pharmaceutical preparation, in particular to a cyproheptadine hydrochloride cream and a preparation method thereof.
- Skin diseases are mostly allergic and inflammatory skin diseases. Except for a few inflammatory skin diseases, patients have varying degrees of itching. In severe cases, it affects the work, life and physical and mental health of patients.
- Glucocorticoids are currently the most commonly used drugs in clinical practice, as well as antihistamines, immunosuppressants, antibacterials and antifungals.
- Glucocorticoids are widely used in non-infectious inflammatory skin diseases, especially dermatitis and eczema allergic diseases, because of their rapid action and remarkable curative effect. Since the introduction of hydrocortisone, dozens of topical glucocorticoids have been synthesized, and some topical preparations of antibiotics or antifungal drugs and glucocorticoids, such as compound triamcinolone acetonide cream, have been developed. However, long-term external use of these drugs may cause skin atrophy, telangiectasia, hyperpigmentation or perioral dermatitis, and may also cause adverse reactions such as secondary infection. A large area of the body can also cause adrenal cortical atrophy and systemic adverse reactions.
- the technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies, and to provide a topical cream for treating dermatitis and eczema with remarkable curative effect - small toxic and side effects, which can prompt the curative effect of the mind.

皮肤病以过敏性、 炎症性皮肤病居多, 除少数炎症性皮肤病外, 患者均有 程度不等的瘙痒, 严重时, 会影响患者的工作、 生活及身心健康。
对于皮炎和湿疹的治疗, 一般采用全身和局部用药相结合方式, 其中局部 用药是皮炎和湿疹治疗的重要手段。 目前临床上糖皮质激素类药物是最常用的 药物, 另外还有抗组胺药、 免疫抑制剂、 抗细菌药和抗真菌药等。
糖皮质激素药由于作用迅速且疗效显著, 在非感染性炎症性皮肤病, 尤其 是皮炎湿疹类过敏性疾病中得到广泛使用。 自氢化可的松上市以来, 至今已合 成了数十种外用糖皮质激素, 并且开发出一些抗生素或抗真菌药物与糖皮质激 素的复方外用制剂, 如复方曲安奈德乳膏等。 然而这些药物长期外用, 可能产 生皮肤萎缩、 毛细血管扩张、 色素沉着或口周皮炎等, 还易发生继发感染等不 良反应。 全身大面积使用, 还可发生肾上腺皮质萎缩和系统性的不良反应。
目前临床上用于治疗皮炎湿疹类皮肤病外用乳膏, 例如, 派瑞松乳膏、 复 方达克宁霜、 皮炎平乳膏、 皮康霜、 皮康王、 恩肤霜等。 上述外用制剂由于抗 炎性弱或止痒性不佳或由于添加抗细菌、 抗真菌药物等, 使应用范围缩小, 产 生依赖性且易继发过敏, 临床治疗不能令人满意。 另一方面, 此类外用乳膏剂 在外观新颖、 独特作用或提示心灵疗效方面存在不足。
