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.     

Rotura del tendón de Aquiles asociada al uso de fluoroquinolonas en pacientes mayores de 60 años: experiencia de un centro de tercer nivel

BackgroundFluoroquinolones have been associated with increased risk of tendinopathy and Achilles tendon rupture (ATR), especially in patients over 60 years of age.MethodsA retrospective study was carried out including patients over 60 years of age with ATR attended in our centre over the period 2000-2017.ResultsWe identified 44 patients with RTA, of whom 18% (8/44) had been previously treated with fluoroquinolones, with a mean age at diagnosis of ATR of 77.37 years and concomitant corticotherapy in 4 of them. In 7 patients, the rupture was spontaneous and all required surgical management. A significantly higher frequency of smoking, concomitant corticotherapy and spontaneous ruptures were found in the group treated with fluoroquinolones.ConclusionsATR is an adverse event that can occur in patients over 60 years of age treated with fluoroquinolones, so an adequate risk-benefit assessment should be carried out in this population, especially in the presence of associated risk factors.
