Embodiment 1

[0034] Purpose:

[0035] Studies over the years have shown that itching is mainly conducted by two types of C fibers, one sensitive to histamine and the other sensitive to chloroquine. Therefore, the animal scratching response induced by subcutaneous injection of histamine or chloroquine is an internationally recognized model of acute pruritus. The purpose of the present invention is to explore whether orthoacine (BLA) can inhibit the acute itching caused by histamine and chloroquine.

[0036] Experimental materials and methods:

[0037]6-8 week C57 mice (body weight 17-20 g, the animals were obtained from the Experimental Animal Center of Sun Yat-Sen University) were used in the experiment. The mice were randomly divided into four groups: solvent+histamine control group, BLA+histamine group, solvent+chloroquine control group and BLA+chloroquine group. Three days before the start of the experiment, the nape of the neck was shaved (at least 3 x 5 cm) under brief anesthesia w...

Embodiment 2

[0053] The application of the aconitin of the present invention in neuropathic pruritus can make the aconitin into different dosage forms for use. To be specific, aconitin can be made into dosage forms including capsules, tablets or granules. Concrete medicine can include aconitin and other pharmaceutically acceptable carriers, and the dosage of each component in the medicine can be adjusted according to the proportioning requirements of the components in the pharmaceutical preparation, and the effective content of aconitin can also be adjusted. It can be calculated according to the requirements of conventional dosage forms such as different dosage forms, 0.01375mg / kg to 0.055mg / kg body weight / d described in Example 1, this example only provides a reference value range here, and is not specifically limited. To further illustrate, the pharmaceutically acceptable carrier can use deodorants, fillers, disintegrants, coloring agents and thickeners, etc. Low-flavoring agents such a...

Embodiment 3

[0055] A tablet containing aconitin, each film-coated tablet containing 0.275 mg aconitin and 130 mg of auxiliary materials. Dissolve aconitin with food grade or pharmaceutical grade ethanol; mix excipients lactose 20mg, powdered sugar 25mg, microcrystalline cellulose 40mg and hydroxypropyl cellulose 10mg, then add aconitin ethanol and mix, then add Appropriate amount of purified water is mixed to make a soft material, which is then made into granules and then dried. Magnesium stearate and sodium carboxymethyl starch are added to the dried granules, pressed into tablets for a few minutes, and then coated with film.

Abstract

The invention relates to the field of medicaments, in particular to the application of aconitin. The preparation of aconitin is used to treat skin pruritus, avoiding the adverse reactions caused by the application of antihistamines, hormones and other drugs, which cannot be used for a long time, and can only be used intermittently, resulting in the recurrence of pruritus. The application of ruconidin for the treatment of skin pruritus has a definite curative effect, no liver and kidney toxicity side effects, and can be taken for a long time to control recurrent skin pruritus and avoid unconscious scratching, which will cause rough skin and lichenification, which can lead to eczema, neuropathy, etc. Secondary lesions such as dermatitis and prurigo nodularis.

The cause of disease of systemic dermatosis is mostly relevant with body metabolic disorder and endocrine abnormality. Common reasons are as follows. Senile skin pruritus is due to the hypofunction of sebaceous glands in the elderly, poor peripheral circulation, and weakened skin water retention function, resulting in dry skin, which is easily stimulated by changes in cold and heat in t...
