Formula and preparation process of oxytetracycline injection
The invention relates to the technical field of oxytetracycline injection, and discloses a formula and a preparation process of the oxytetracycline injection, the oxytetracycline injection comprises 40%-60% of acetamide, 0.5% of sodium formaldehyde sulfoxylate, 20% of oxytetracycline hydrochloride (folded to be pure) and 1.8% of magnesium oxide, the folded to be pure of the oxytetracycline hydrochloride is 95% or above, the particle size of the magnesium oxide is 10-15 microns, and the particle size of the magnesium oxide is 10-15 microns. The sodium formaldehyde sulfoxylate is an efficient composite adsorbent. According to the oxytetracycline injection disclosed by the invention, the oxytetracycline injection is stable and efficient in drug release by optimizing the components of the liquid medicine and finely controlling the preparation process, and has smaller irritation and better drug effect. Meanwhile, the oxytetracycline injection provided by the invention is simple and feasible in preparation process and convenient to operate, and the sterility and the stability of the liquid medicine can be ensured. In addition, the oxytetracycline injection formula and the preparation process provided by the invention also have the advantages of low cost, short preparation period, strong adaptability and the like, so that the oxytetracycline injection has wide application prospects..
