Objective: To develop and characterize multiple-unit-type oral floating microsphere of famotidine to prolong gastric residence time and to target stomach ulcer. Methods: The floating microspheres were prepared by modified solvent evaporation method. Eudragit S-100 was used as polymer. Microspheres were characterized for the micromeritic properties, floating behavior, entrapment efficiency and scanning electron microscopy. The in-vitro release studies and floating behavior were studied in simulated gastric fluid at pH 1.2. Different drug release kinetics models were also applied for all the batches. Selected formulations were also subjected for X-ray radiographic study. Results: Floating microspheres were successfully prepared by modified solvent evaporation technique. Microspheres showed passable flow properties. The maximum yield of microspheres was up to (95.11±0.35)%. On the basis of optical microscopy particle size range was found to be ranging from (52.18±182.00) to (91.64±5.16) μm. Scanning electron microscopy showed their spherical size, perforated smooth surface and a cavity inside microspheres. Microspheres were capable to float up to 20 h in simulated gastric fluid. X-ray radiographic studies also proved its better retention in the stomach. Conclusions: On the basis of the results, such dosage forms may be a good candidate for stomach targeting and may be dispensed in hard gelatin capsules.

Introduction: This observational study was conducted to assess the knowledge, attitudes, and perceptions (KAP) of Malaysians toward participating in clinical trials. It also aimed to look for factors that will influence people’s willingness to participate in trials. We planned and developed future outreach, education tools, and recruitment strategies to increase clinical trial enrolment. Methods: A cross-sectional study was carried out on a randomly selected sample of 398 Malaysian literate adults. An online questionnaire was created and distributed to the respondents. Descriptive statistics were presented in the form of frequency and percentages. The chi-square test was employed to find the association between independent variables. Results: The majority had good knowledge (61.3%) and high awareness (88.7%) of clinical trials. However, most of them were not willing to take part in a clinical trial if they were assigned to a group of unlicensed drugs (90.2%) or randomly assigned (66.1%). The main reasons for participating in trials were recommendations from doctors (46.5%) and the potential for their own benefit (45.7%). Younger age was positively associated with the necessity and confidentiality of clinical trials. Most respondents indicated negative perceptions towards the safety of clinical trials regardless of demographic variables. Conclusion: We gained a better understanding of Malaysian people who are potential participants in a future clinical trial. These findings could help clinical researchers improve their understanding of the participants and develop effective outreach strategies for clinical trial recruitment and retention.
