                     【Market analysis】
                     This product is an imported drug product of Baxter Company of the United States. It has been sold in China since October 1999, and its product name is "Schneivita, Cernevit". The market retail price before 2005 was 38 yuan/piece, and the wholesale price was 26 yuan/piece. Due to the low price and the high production and logistics costs of imported products, Baxter has gradually abandoned the sales of this product in 2004 and changed to the general agent of a domestic pharmaceutical company. The current market retail price of this product has increased. It is 140 yuan/piece, which is 5 times that of water-soluble vitamin for injection (Jiuweita) and 7 times that of compound vitamin injection (4) (Zivita). The cost of the raw materials of this product is only close to 0.8 yuan/piece. Therefore, the clinical application of this product is significantly better than the water-soluble vitamin for injection, fat-soluble vitamin for injection (II) and compound vitamin injection (4) on the domestic market. This product has a very large market potential. The domestic development of this product has broad market prospects and will become a strong profit growth point for enterprises.
                     Market analysis of other multi-vitamin injections:
                     On September 18, 2005, the National Development and Reform Commission announced the "Notice on Reducing the Retail Prices of 22 Drugs Including Cefuroxime". The new round of drug price reductions began on October 10 this year. The price reduction is still dominated by antibiotics. There are 22 kinds of varieties involved in the price reduction, of which 16 antibiotics and 6 new medicines in the medical insurance catalogue are all clinically used varieties, mainly ceftriaxone, levofloxacin, ofloxacin, azithromycin, gram Linmycin and other antibiotics are the mainstay, as well as thymosin, interferon, water-soluble multivitamins (water-soluble vitamins for injection) and other newly entered medical insurance catalogs.
                     The maximum retail price of water-soluble vitamins for injection has dropped to 15 yuan per bottle. This variety will basically lose its market competitiveness. Most hospitals will soon abandon the clinical use of water-soluble vitamins for injections and look for new multi-vitamin injections. Variety. Once water-soluble vitamins for injection are withdrawn from the market, 12 multivitamins for injection will quickly occupy most of the market share of multivitamin injections.
                At present, there is only one domestic product approved last year (Shanxi Pude Pharmaceutical Co., Ltd.). The API has not passed GMP certification, and the preparation is currently not produced or sold.

                Project 2: Technology transfer or cooperative production of raw materials and capsules of tauroursodeoxycholic acid
                1. Project name
                Technology transfer or cooperative production of raw materials and capsules of tauroursodeoxycholic acid
                English name: Tauroursodeoxycholic Acid
                Molecular formula: C26H45NO6S.2H2O
                Basic information: The chemical name of tauroursodeoxycholic acid (TUDCA) is 3α, 7β dihydroxycholanoyl-N-taurine, which is composed of the shuttle group of ursodeoxycholic acid (UDCA) and the amino group of taurine Combined bile acid formed by shrinking between. TUDCA was discovered in bear bile in 1902. It is the main bile acid in bear bile and has antispasmodic, anticonvulsant, anti-inflammatory and gallstone-dissolving effects. Tauroursodeoxycholic acid (tauroursodeoxycholic acid, 1) is the active ingredient of bear bile, and its chemical name is 2-[[(3α, 5β, 7β)-3,7-dihydroxy-24-oxocholestane-24 -Yl]amino]ethanesulfonic acid dihydrate, developed by the Italian Besdi Pharmaceutical Factory, was first marketed in Italy in 1991, and was approved for sale in China under the trade name taurolite in 2007. It is mainly used in clinical practice Treatment of cholesterol gallstones, primary sclerosing cholangitis, primary biliary cirrhosis and chronic hepatitis C. Clinical studies have shown that compared with ursodeoxycholic acid, the dissolution rate is faster, the total dissolution rate is increased, and there are no obvious adverse reactions. No domestic company has been approved for listing!
                2. Registration category
                API: 3 categories; Capsules: 6 categories
                3. Preparation
                Capsule 250mg
                4. Indications
                Dissolve cholesterol stones.
                * There are one or more cholesterol stones with a diameter less than 2 cm visible on X-ray in the gallbladder or bile duct.
                * Refused to surgical treatment or not suitable for surgical treatment.
                * Duodenal intubation bile examination confirmed cholesterol oversaturation.
                5. Pharmacology and Toxicology:
                Tauroursodeoxycholic acid can increase the secretion of bile acids, leading to changes in the composition of bile acids and increasing the content of bile. Tauroursodeoxycholic acid can also inhibit the synthesis of cholesterol in the liver, reduce the amount of cholesterol and cholesterol esters in the bile, and the saturation index of cholesterol, thereby facilitating the gradual dissolution of cholesterol in the bile.
                In chronic toxicology experiments, the oral doses for dogs and rats were 400mg/kg (dogs) and 1200mg/kg (rats) respectively, and no toxicity was reported.
                In view of the fact that bile acids can pass through the placental barrier, the drug should not be used in pregnant women for safety reasons. Although rabbits and rats received high-dose oral administration, there was no embryo toxicity or teratogenic effects.
                In the five required studies, the results obtained failed to suggest any mutagenic effects of Taurot.
                A 2-year study on the carcinogenicity of this product has been carried out on rats taking large doses of drugs (up to 300mg/kg/day), and it has proved that this product has no carcinogenic effects.
                6. Research progress: The pre-production research is reported, and the pilot test and industrial optimization of APIs and preparations have been completed. Quality research has been carried out.
                Project 3: Technology transfer or cooperative production of vitamin A palmitate ophthalmic gel
                1. Project name
                Vitamin A Palmitate Eye Gel
                2. Basic introduction
                [Properties] This product is a milky white gel with no visible particles.
                [Indications/Functions and Indications] As an adjuvant treatment for corneal protection: dry eye caused by various reasons (for example: Sjogren's syndrome, neuroparalytic keratitis, exposure keratitis); conjunctiva and conjunctiva due to lack of tear film protection Symptoms of corneal irritation.
                【Specification Model】5g:5000IU
                [Pharmacology and Toxicology] Due to the long retention time, this product is suitable as a substitute for tear fluid to be used in the treatment of insufficient tear secretion and "dry eye syndrome". The latter is due to the instability of the tear film caused by the low quality of tear fluid and then high secretion. The higher viscosity enhances the protective effect of the gel through physical lubrication. The added vitamin A eliminates the symptoms of corneal epithelial dehydration and enhances the therapeutic effect. Vitamin A (retinol) is necessary for the normal differentiation of epithelial cells. Deficiency of retinol leads to a decrease in goblet cells, atrophy of epithelial cells and proliferation of conjunctival basal cells.
                [Pharmacokinetics] The good local permeability of topical retinol has been confirmed in healthy rabbit eyes, and it is impossible to conduct research on the degree of penetration or distribution and persistence of human eyes.
                3. Registration classification
                API: 6 categories; preparation: 6 categories
