An eco-friendly HPLC-UV method for the determination of risedronate in its bulk and tablet dosage form with application to content uniformity,dissolution and stability testing

Risedronate is a nitrogen-containing bisphosphonate for the treatment and prevention of postmenopausal osteoporosis. The current work aims to develop a novel green HPLC-UV method for the rapid analysis of risedronate sodium in bulk and tablet formulation. The analyzed samples were separated on Waters Atlantis dC18 (150 mm × 3.9 mm; 5 μm) column using a green mobile phase consisting of potassium phosphate buffer pH 2.9 and potassium edetate buffer pH 9.5 in a ratio of 1:2, the final pH was adjusted to 6.8 with phosphoric acid, the mobile phase was pumped at a rate of 1.0 mL/min, with column temperature set at 30 °C, eluted samples were detected at 263 nm and the chromatographic run time was 3.0 min. The method was found to be linear over the concentration range of 14–140 μg/mL with a correlation coefficient (r²) of 0.9994. Accuracy and precision were evaluated from three QC samples (LQC, MQC and HQC) together with the five calibrators where the percentage accuracy was found to be 101.84%. Processed quality control samples of risedronate sodium were tested for stability at different conditions, short term, long term and freeze- thaw stability. The current method was further extended to study the content uniformity of Actonel® tablets following United States Pharmacopoeia (USP) guidelines. The proposed method was fully validated as per ICH guidelines.     

Oral Dispersible System: A New Approach in Drug Delivery System

Dosage form is a mean used for the delivery of drug to a living body. In order to get the desired effect the drug should be delivered to its site of action at such rate and concentration to achieve the maximum therapeutic effect and minimum adverse effect. Since oral route is still widely accepted route but having a common drawback of difficulty in swallowing of tablets and capsules. Therefore a lot of research has been done on novel drug delivery systems. This review is about oral dispersible tablets a novel approach in drug delivery systems that are now a day''s more focused in formulation world, and laid a new path that, helped the patients to build their compliance level with the therapy, also reduced the cost and ease the administration especially in case of pediatrics and geriatrics. Quick absorption, rapid onset of action and reduction in drug loss properties are the basic advantages of this dosage form.

Systematic Evaluation(Meta-analysis)of the Efficacy and Safety of Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)in the Treatment of Suppurutive Tonsillitis in Children

To systematically evaluate the efficacy and safety of Pudilan Xiaoyan Oral in Liquid(蒲地蓝消炎口服液)in the treatment of suppurative tonsillitis in children.In WanFang,CNKI,VIP,CBM,PubMed,Embase and Corchrane and other databases,relevant literatures about Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)in the treatment of pediatric suppurative tonsillitis were searched.The retrieval time was from the establishment of the database to April 2019.Relevant randomized controlled trials were extracted.The control group was treated with conventional antibiotics,and the observation group was treated with Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)based on the control group.After they were summarized and analyzed,Cochrane Handbook 5.1 evaluation standard and RevMan 5.3 software were used to determine the quality of literature.A total of 172 literatures were retrieved and 23 randomized controlled trials were included.A total of 1188 children were in the experimental group while 1175 children were in the control group,involving 2363 children with suppurative tonsillitis.Meta-analysis showed that the total effective rate of Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)combined with routine treatment was better than that of routine treatment(RR=0.88,95%CI(0.86,0.91),P<0.00001);Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)combined with routine treatment in children was better than that of routine treatment alone in term of temperature recovery,sore throat time,the reduction of tonsil purulent secretion.There were few reports of adverse reactions and no serious adverse reactions.To sum up,Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)combined with routine treatment can significantly improve the efficacy of children with suppurative tonsillitis,but due to the low quality of the included literature,it should be used cautiously.It is suggested that clinical randomized controlled trials should be designed with large sample size,multi-centers and conforming to international standards to improve the quality of evidence.
