ABSTRACT

OBJECTIVE To prepare the Eriodictyol chewable tablet and to evaluate its quality. METHODS The chewable tablet was prepared by the wetting granulation method by using microcrystalline cellulose (MCC) and mannitol as fillers, polyvinylpyrrolidone (PVP) as adhesive, citric acid and sucralose as flavor correction agents, magnesium stearate as lubricant. The comprehensive evaluation was conducted on Eriodictyol chewable tablets with the dosage of each excipient as a factor using the appearance, taste, flavor and texture as indicators. The ratio of excipients was optimized by orthogonal test, and the quality of Eriodictyol chewable tablets prepared by optimized formulation was evaluated in terms of appearance, weight difference, hardness, fragility, eriodictyol content, dissolution and content uniformity. RESULTS The optimal formulation was as follows: 26.4% eriodictyol (50 mg each piece), 45% mannitol, 25% MCC, 0.3% citric acid, 0.3% sucralose, 1% magnesium stearate, 2% PVP (preparing 5% solution using purified water). The scores of 3 batches of Eriodictyol chewable tablets in the validation test were 8.76, 8.75 and 8.80 (RSD=0.30%, n=3), respectively. The Eriodictyol chewable tablet had a complete appearance and a smooth surface; the average tablet weight was 192.57 mg, the average hardness was 57.36 N, the fragility was 0.09%, the average content of eriodictyol per tablet was 50.74 mg, the cumulative dissolution within 30 min was exceeding 80%, and the content uniformity was 5.51. CONCLUSIONS Eriodictyol chewable tablet prepared by optimal formulation conforms to the requirements of the 2020 edition of Chinese Pharmacopoeia.

ABSTRACT

OBJE CTIVE To investigate the clinical characteristics of a dverse drug reactions of asparaginase-associated pancreatitis(AAP),so as to provide reference for clinical safe medication. METHODS Analysis and identification were performed on a severe adverse reaction case of acute pancreatitis complicated with diabetic ketoacidosis and liver injury in a patient with acute lymphoblastic leukemia in our hospital after using pegaspargase. Retrieved from Wanfang database ,CNKI,PubMed and Embase database,case reports of AAP were collected and summarized in terms of patient demographics ,drug use ,incubation period and adverse reaction outcome. Combined with this case ,the disease characteristics and potential risk factors of AAP were analyzed and discussed. RESULTS After analysis and identification ,it was determined that AAP occurred in this patient. A total of 47 case reports were retrieved from the database ,and a total of 52 patients(including this patient )were included in the analysis ,including 29 males and 23 females,mainly minors (65.4%). L-asparaginase was the main asparaginase preparation that causes AAP (80.8%). Gastrointestinal symptoms were the main prodromal symptoms (92.3%),which could be accompanied by other asparaginase related adverse reactions. AAP could occur after 1-33 times of administration ,and the median latency was 14 days after administration;compared with children ,median latency of AAP in adult patients was shortened significantly (11 d vs. 16 d,P= 0.049);the median latency of AAP had longer tendency in patients treated with pegaspargase than that of L-asparaginase (17 d vs. 12.5 d,P=0.490). Of the cases included in the analysis ,8 patients died due to AAP ,1 of which was related to re-exposure to asparaginase preparations. CONCLUSIONS Acute pancreatitis is a serious and potentially fatal adverse drug reaction of ; asparaginase preparations. Clinical medical staff should pay attention to the characteristics of AAP ,consider the possibility : of AAP when the patients have gastrointestinal symptoms and do a good job in patient education and pharmaceutical care to minimize the damage caused by AAP to patients.
