Camptothecin medicament injection solution and injection and preparation method thereof

InactiveCN101708156AGood dispersionSolve problems that are difficult to make into injectionsOrganic active ingredientsEmulsion deliverySolubilityMedication injection
The invention relates to the technical field of medicaments, in particular to a camptothecin medicament injection solution and an injection and a preparation method thereof. The invention provides a camptothecin medicament injection which is good in stability, high in curative effect and low in toxicity and consists of the camptothecin medicament injection solution and a disperse medium, wherein the camptothecin medicament injection solution consists of a medicament active component, a stabilizing agent, a pH value regulator and an injection solvent. The medicament active component of the camptothecin medicament injection solution is a camptothecin medicament mainly existing in the form of a lactonic ring, which can improve the curative activity of the medicament and reduce toxic side effects; and the disperse medium is an injection emulsion, which can improve the dispersion degree of the camptothecin medicament and solve the problem that the camptothecin medicament is difficult to be prepared into the injection due to poor water solubility. The camptothecin medicament injection solution and the injection emulsion are packed and then stored respectively, and are mixed uniformly before use for intravenous administration, so the stability of the medicaments stored for a long time can be improved. The invention provides an intravenous injection which has low toxicity and is save and convenient to store for camptothecin medicaments.

Targeting antitumor drug using magnetic micro-nano material to destroy tumor blood vessels under driving of alternating magnetic field or radio frequency

The present invention discloses a novel use of a magnetic micro-nano material. The new use is application of the magnetic micro-nano material in manufacture of a targeting tumor treatment drug, the magnetic micro-nano material has all the following properties: (1) the magnetic micro-nano material is magnetic, sol that the magnetic micro-nano material can produce mechanical destructive effects on tumor blood vessel endothelial cells under driving of an alternating magnetic field or radio frequency; (2) the magnetic micro-nano material has a hydrophilic surface; (3) the magnetic micro-nano material has certain electronegativity on surface; and (4) the particle size range of the magnetic micro-nano material is 10-500nm, so that the magnetic micro-nano material has rigidity (namely, is not easy to deform). The magnetic micro-nano material can be specifically gathered and retained in tumor blood vessel parts by EPR effect after intravenous injection, and the mechanical destructive effects produced under driving of the alternating magnetic field or radio frequency can act on the tumor blood vessel endothelial cells highly selectively to further destroy tumor blood vessels to lead to tumor rapid necrosis and achieve the efficient tumor targeting treatment purpose.

Aprepitant intravenous injection emulsion as well as preparation method and application thereof

The invention relates to aprepitant intravenous injection emulsion as well as a preparation method and an application thereof, and belongs to the technical field of pharmaceutics. The aprepitant intravenous injection emulsion is prepared from components in percentage by mass as follows: 0.05%-3% of aprepitant, 5%-30% of an oil phase solvent, 1.2%-18% of an emulsifier, 0.03%-0.6% of a stabilizer and 1%-5% of an isoosmotic adjusting agent, the injection emulsion further contains a pH regulating agent and the balance of water for injection, and pH value of the injection emulsion is 5.5-8.0. The aprepitant intravenous injection emulsion contains no low-carbon chain alcohol such as ethanol and the like, meanwhile, the quality requirement for a marketed product can be met by technological innovation and adjustment, and clinical use safety of the aprepitant intravenous injection emulsion is greatly improved; direct intravenous injection is utilized during clinical using, and dilution is not needed; the aprepitant intravenous injection emulsion can be used for treating acute and tardive nausea and vomiting caused by high-dose cis-platinum combined high-dose sensitizing cancer chemotherapy,and nausea and vomiting in early stage and middle stage of tumor chemotherapy are reduced.

Medical intravenous injection auxiliary device

InactiveCN109621101AEliminate fearPositive self-suggestionIntravenous devicesMassageIV injection
The invention provides a medical intravenous injection auxiliary device. The medical intravenous injection auxiliary device comprises a handle supporting device and a skin irritation device mounted onthe hand supporting device through a connecting part. The hand supporting device comprises a supporting seat. The supporting seat stretches upwards to form a supporting plate, and a hand supporting rod is horizontally mounted at the upper end of the supporting plate. The skin irritation device is in a cuboid shape and internally comprises multiple massage parts making contact with skin to generate irritation, and multiple massage holes allowing massage heads of the massage parts to stretch out are formed in the skin irritation device. The connecting part comprises a fixing pipe mounted on thesupporting seat, and an adjusting pipe with one end rotationally connected into the fixing pipe, or comprises an elastic connecting band and a lock knob matched with the connecting band. The skin irritation interference device at least comprises a body, a supporting body, a power part and the massage parts. The device makes contact with the skin at certain rhythm and actions to generate an irritation interference effect, the skin is in slight point contact intermittently, a patient is relaxed, the attention of the patient to needle inserting portions is dispersed, and therefore the pain senseis relieved.
