34 results about "Carbocisteine" patented technology

Carbocisteine, also called carbocysteine, is a mucolytic that reduces the viscosity of sputum and so can be used to help relieve the symptoms of chronic obstructive pulmonary disorder (COPD) and bronchiectasis by allowing the sufferer to bring up sputum more easily. Carbocisteine should not be used with antitussives (cough suppressants) or medicines that dry up bronchial secretions.

Method and system for recovering waste water generated in carbocisteine production

The invention discloses a method and system for recovering waste water generated in carbocisteine production. The system comprises a bipolar membrane electro-dialysis desalination system and a recovering system; the recovering system comprises an acid concentrating and recovering system, a base concentrating and recovering system and a carbocisteine concentrating and recovering system. With the adoption of the system, salts in the waste water generated in carbocisteine production can be converted into corresponding acid and base so as to be removed; the obtained acid and base can be directly used in the carbocisteine production process or be used in the carbocisteine production process after an advanced treatment; the carbocisteine in the waste water is further recovered by using a carbocisteine concentrating crystallizing system. By treating the waste water generated in the carbocisteine production by using the method, organism pollution, salt pollution and ammonia nitrogen pollution are avoided; in addition, the recovered acid and base can be reused in the carbocisteine production process to realize zero emission; by using the recovered carbocisteine, the carbocisteine yield is increased and the cost of the method provided by the invention can be further reduced.

The invention relates to carbocisteine syrup with improved water solubility and a preparation method of the carbocisteine syrup. The method comprises the following steps: weighing syrup substrate, adding an appropriate amount of purified water into the syrup substrate, carrying out complete boiling so that the syrup substrate is dissolved, carrying out filtering, carrying out standing for cooling till the temperature is 40-60 DEG C, and carrying out shaking till the product is uniform, thus obtaining simple syrup; weighing an active pharmaceutical ingredient, namely, carbocisteine, adding carbocisteine into an appropriate amount of water, slowly adding with an appropriate amount of sodium hydroxide solution under stirring, so that carbocisteine is completely dissolved (alkali is added according to the molar ratio of 1 to 1 for forming salt), adding with an appropriate amount of a preservative and an appropriate amount of a corrigent, and carrying out sufficient stirring; adding the carbocisteine solution into the simple syrup; enabling the relative density of the liquid medicine to be 1.08-1.25; adding with an appropriate amount of boiling water, carrying out stirring till the uniform state is reached, and carrying out filtering after the assay was approved after the liquid medicine is cooled to be 50 DEG C or below, and thus obtaining the filtrate, which is the syrup capable of relieving cough and eliminating phlegm. The method provided by the invention is simple in process and low in cost, the obtained carbocisteine syrup is good in water solubility, the method is suitable for industrial production, and thus the difficulties that carbocisteine has difficulty in dissolving in water, and the bioavailability is low are solved.

Carbocisteine composition freeze-drying tablet and preparation method thereof

The invention provides a carbocisteine composition freeze-drying tablet and a preparation method thereof, and relates to technical fields of medicines and medicine production. The carbocisteine composition freeze-drying tablet comprises carbocisteine, starch and cane sugar, wherein the starch and cane sugar are taken as auxiliary materials; by performing heating technology processing on the common corn starch, the binding effect and disintegration effect of the starch in the tablet can be improved, the formability of the tablet can be improved, and the carbocisteine composition freeze-drying tablet only requires two auxiliary materials, namely starch and cane sugar. The carbocisteine composition freeze-drying tablet adopts a freeze-drying technology of twice cooling and twice heating up which can ensure that the formability of the tablet is better, and improves the dissolution rate of the tablet, so that the bioavailability of the tablet is improved; the tablet overcomes the disadvantage of the common carbocisteine tablet, reduces the variety and the use level of the auxiliary materials in the carbocisteine tablet, is high in dissolution rate and high in bioavailability, and guarantees the curative effect and safety of clinical medication.
