Abstract


In order to change the Candesartan Cilexetil tablet prescription obsoletely,the production craft backwardness condition,thus the thorough settlement product outward appearance difference, dissloution degrees problem,further enhanced the labor productivity,the promotion product quality,this article has carried on the Candesartan Cilexetil preparation craft and quality research. The research choice fluid bed equipment, and factor analysis, orthogonal experiment, the screening definite excepients, optimizes the Candesartan Cilexetil tablet prescription and the production craft ; Prepares 6 batch of samples, carries on the contrast with 6 bath of original prescription product quality, has discussed in the manufacture process the tablet quality and the particle intermediate micromeritics nature relations; Carried on dissolution and the degradation compound examination methodology research, carried on the sample stable inspection. Main findings: The prescription for Candesartan Cilexetil 8mg;MCC 40mg;lactose 40mg;starch 20mg;PEG 6000 32mg;pregelatinized starch 20mg;Sodium carboxy methyl cellulose 5mg;magnesium stearate 0.5%;10%PVP ethanol-soluble fluid right amount;Using the Candesartan Cilexetil tablet new prescription and the manufacture craft production product , had the distinct enhancement compared with the original product quality; Through after the particle characteristic research analysis, obtains the particle quality control target to be as follows: The particle-size distribution standard deviation 1.83-2.11,stops the angle of repose to be smaller than 40°,the particle compressibility is smaller than 18%;Has established the quality control mathematical model which the particle-size distribution standard deviation and between the tablet weight variation, between the particle compressibility and tablet hardness and friability change; Enhanced dissolution standard in the original Candesartan Cilexetil tablet quality standard foundation. We obtained the new prescription and the production craft through this topic research, and obtained the quality stable sample, formulated the new product quality standard. The study has provided reliable basis for the digitization production and the enhancement on production process quality controllability.
