125 results about "Dexamethasone Sodium Phosphate" patented technology

A sodium phosphate salt form of Dexamethasone, a synthetic adrenal corticosteroid with potent anti-inflammatory properties. In addition to binding to specific nuclear steroid receptors, dexamethasone also interferes with NF-kB activation and apoptotic pathways. This agent lacks the salt-retaining properties of other related adrenal hormones. (NCI04)

Pulmonic targeting immuno nano liposome and preparation method thereof

The invention, belonging to the technical field of medicament, relates to an immuno liposome with pulmonic target activity and a preparation method thereof. The immuno liposome disclosed herein comprises pulmonic surfactant protein (SP) A polyclonal antibody, actie pharmaceutical ingredients and a nano liposome, wherein, dexamethasone sodium phosphate (DXM) and other glucocorticoids are used as the actie pharmaceutical ingredients, the nano liposome is used as a carrier, and the SP-A polyclonal antibody is used as a specific pulmonic targeted agent. The immuno nano liposome disclosed herein has the advantages of definite pulmonic target activity, and efficient and stable realization of the targeted conveying of the actie pharmaceutical ingredients to lung, so that maximum concentration ofDXM in the lung is increased by 5.08 times compared with common medicines, and the area under curve when 12 hours after injecting the medicine is increased by 40.21 times. According to the invention,the dosage of glucocorticoids can be reduced, the curative effect on lung diseases can be improved, and systematic side effect can be reduced at the same time. The invention has new values for clinicapplication.

Compound ofloxacin injection for animals for treating postnatal infection and preparation method thereof

The invention discloses a compound ofloxacin injection for animals for treating postnatal infection and a preparation method thereof. The invention aims to provide a compound ofloxacin injection for the animals which has quick response on treating the postnatal infection of livestock, is effective and efficient and can treat both principal and secondary aspects of diseases, and a preparation method thereof. Each 100L of injection comprises the following components: 0.5 to 10kg of ofloxacin, 3 to 15 of billion units of kanamycin sulfate, 0.06kg of dexamethasone sodium phosphate, 0.02 to 0.1kg of bethanechol chloride, 1,000ml of hydrochloric acid, and the balance of water for injection. The injection has double functions of bacteria inhibition and sterilization by using the ofloxacin in combination with the kanamycin sulfate, reduces the probability that bacteria produce the drug resistance, and increases the sensitivity of the bacteria; in addition, the dexamethasone sodium phosphate has anti-inflammatory, detoxicating and antiallergic functions; and the bethanechol chloride stimulates the intestines and stomach as well as uterine smooth muscle to creep. The product treats both principal and secondary aspects of diseases on the postnatal infection of dams and complicating diseases thereof, and can accelerate the postpartum recovery of the dams.

Synergetic compound analgin injection and preparation method thereof

The invention relates to a synergetic compound analgin injection and a preparation method thereof. The injection comprises the following components by weight in 100 milliliters: 10 to 30g of analgin, 2 to 4g of antioxidant, 50 to 150mg of dexamethasone sodium phosphate, 0.05g of EDTA (ethylene diamine tetraacetic acid)-Na2, injection water filled until the amount reaches 100ml, and proper pH regulating agent, wherein the usage of the pH regulating agent is sufficient to regulate the pH value of the system to be between 5.5 and 6.5. The preparation method comprises the following steps of adding the EDTA-Na2, the antioxidant and the analgin into the injection water, stirring until the EDTA-Na2, the antioxidant and the analgin are completely dissolved to prepare liquid A; dissolving the dexamethasone sodium phosphate with trace injection water to prepare liquid B; adding the liquid B into the liquid A, uniformly stirring, continuously stirring for 20 minutes, regulating the pH value to be between 5.5 and 6.5, and fixing the volume to 100ml; filtering medicinal liquid, filling the filtrate into a bottle with a filling and sealing machine; and sterilizing for 30 minutes at a temperature of 115 DEG C and at a pressure of 0.2MPa, and cooling and outputting to obtain a finished product. The dexamethasone sodium phosphate is added into the injection reasonably and compatibly, so that the antipyretic effect is reinforced, and the function of anti-inflammation and anti-allergy are given at the same time.
