Abstract Objective To evaluate in vitro quality of enteric-coated 50 mg diclofenac sodium tablet formulations on Saudi market. Results A reference and seven generic (G1-7) formulations were commercially available in December 2019/January 2020 and were assessed within 25–75% of manufacture-expiration period. Weight variation (range as% difference from mean, n = 20), active substance content (ASC, mean (SD) as% difference from label, n = 20), hardness (mean (SD), n = 10), and friability (% weight loss, n = 20) were 97–103%, 102.0% (3.4%), 15.4 (1.1) kg, and 0.24%, respectively, for the reference. For G2-7, they were ≤ ±5%, 98.6% (4.0%) to 109.9% (1.8%), 11.9 (0.9) to 18.3 (0.8) kg, and ≤ 0.00 to 0.75%, respectively. G1 ASC, hardness, and friability were 111.3% (1.7%), 20.1 (1.7) kg, and 1.10%, respectively. Disintegration time (n = 6) and dissolution profile (n = 8) were also determined. No formulation disintegrated or released ˃ 0.1% of label ASC in 0.1 N HCl for 2 h. The reference disintegrated in 15:00 min:seconds and released a mean (range) of 100% (99–103%) of label ASC by 45 min in phosphate buffer (pH = 6.8). G1-7 disintegrated in 8:53 to 20:37 min:seconds and released 81% (69–90%) (G1) to 109%. Except for borderline performance of G1, all formulations passed in vitro quality tests according to United States Pharmacopoeia.

Background: Tablets must be able to release the active drug in the gastrointestinal tract for absorption. The release profile of solid pharmaceutical dosage formulations can be quantified by assessing the disintegration and dissolution times tests. Binders are adhesives either from sugar or polymeric material that are added to tablet formulations to provide the cohesiveness required for the bonding together of the granules under compaction to form tablets.Objective: The objective of the study was to formulate and assess ibuprofen tablets using different concentrations of binders (Acacia and Gelatin).Methods: The granules were prepared using wet granulation method and analysed for flow properties based on USP/NF protocols. After granule compression, the tablets release profiles were thereafter assessed via the tablet dissolution and disintegration tests.Results: Weight variation, thickness and diameter were within the acceptable values for all batches indicative of a uniform flow. Batches with binder concentrations of 10 % and 20 % failed disintegration test due to a disintegration time above 15 min while the release rate for batches 1 and 4 was about 88 % in 60 min as against the other batches whose release rate was less than 50 % in 60 min as a result of increasing their binder concentrations.Conclusion: The study concluded that increasing the concentration of acacia and gelatin above 5% led to a decrease in percentage of drug released and an increase in disintegration time above 30 mins because 5% batches gave the best release profiles.

A number of epidemiological studies have shown the Association of migraine with peptic ulcer disease (JB), however, the processes underlying the pathogenesis and features of the course of these diseases have not been fully studied. Material and methods. A comprehensive examination of the gastrointestinal tract was performed in 114 patients with migraine. Focused on the major clinical and psychological characteristics of patients depending on the availability of gastroduodenopathies, especially pain therapy and serotonin levels in the blood serum. Results. In 18.4% of patients with migraine, regardless of its type, erosive and ulcerative lesions of the stomach and duodenum were detected. In patients with chronic migraine, gastric ULCER developed more often (PF =0.022), the clinical features of the combination of migraine and ULCER were more pronounced intensity of abdominal pain and heartburn. High (5 or more times a week) frequency of nonsteroidal anti-inflammatory drugs (NSAIDs) was an important ulcerogenic factor in patients with migraine. Serotoninergic hypofunction can be discussed as a mechanism that determines the comorbid relationship of migraine and JB. The combination of migraine with NSA contributed to the formation of a more severe course of migraine. In assessing the quality of life indicators of all scales in such patients were lower . Gastropathy can be considered as an additional factor of migraine chronization, requiring appropriate therapeutic interventions to improve the quality of life of patients.

Methods: The general quality parameters of these tablets like weight variation, hardness, thickness, diameter, friability, disintegration time and also dissolution time were evaluated according to the established protocols. For measuring weight variation, an electric analytical balance was used. The hardness, thickness and diameter were determined by an automated hardness tester. Friability was measured by a friabilator. Disintegration time and dissolution time were analyzed by disintegration apparatus and dissolution tester respectively. Results: In this study, all the five brands of the tablets passed the BP or USP standards for in vitro evaluation tests with a very slight deviation. All brands complied with the standards for weight variation (550.1±5.88 mg to 631.1±4.71 mg), hardness (121.60±6.6 N to 220.20±7.6), disintegration time (3 minutes 15 seconds to 5 minutes 30 seconds). However, in case of friability, although brand A showed slight deviation, the remaining had shown the satisfactory results with the standard. In addition, the drug release rate of different brands of paracetamol was satisfactory within 30 minutes and ranged from 90.88% to 103.75%. Conclusion: It can be concluded that almost all the tablets of paracetamol purchased from retail outlets in Bangladesh are manufactured and marketed according to GMP. Further work is recommended on bioequivalence of these tablets.

Due to more versatility and comfort, mouth dissolving tablets are the most advanced type of oral solid dosage forms. Compared to conventional tablets, it increases the effectiveness of APIs by dissolving within a minute in the oral cavity after contact with less saliva, without chewing and without the need for water for administration. Mouth Dissolving Tablets of Ketorolac tromethamine were prepared by direct compression method using various superdisintegrants like crospovidone, Croscarmellose sodium, and Sodium starch glycolate in different concentrations. Prepared tablets were evaluated for hardness, friability, weight variation, disintegration time, wetting time and in vitro drug release. Results of pre-compression and post-compression studies of all formulations were found within the standard limits. The tablets of all the batches were found to release more than 80% of drug in 5 minutes, which is the desired quality of mouth dissolving tablets that helps in faster absorption of the drug and quick onset of therapeutic effect. The the order of dissolution of various disintegrants was found to be Crospovidone˃ SSG˃ CCS. There was no significant variation in drug content of drug during stability studies for selected batch F3 in accelerated conditions over three months. It was concluded from the study that fast release of Ketorolac tromethamine from formulation F3 may reduce onset of drug action with better patient compliance.
