    Orodispersible tablets disintegrate rapidly (within 3 minutes) in the oral cavity and release the medicament before swallowing. The mode of disintegrant addition might affect the properties of orodispersible tablets. The objective of this study was to formulate and evaluate orodispersible tablets by studying different modes of disintegration addition with varying concentrations of disintegrants. The wet granulation method was used to produce the orodispersible tablets. Two methods of disintegration addition were compared (i.e., intragranular, extragranular). Three disintegrants (i.e., cornstarch, sodium starch glycolate, crospovidone) were used at three levels (5%, 10%, and 15%) in the study. The formulations were tested for the powder flowability (angle of repose) and characterized physically (hardness, weight, thickness, friability, disintegration time). The mangosteen pericarp extract was used as a model active pharmaceutical ingredient to be incorporated into the optimum formulation. It was observed that the extragranular method produced granules with better flowability compared to that of the intragranular method. Crospovidone was found as the most efficient disintegrant among the three. The optimum formulation selected was one with the highest concentration of crospovidone (15%), which showed the fastest disintegration time. The mode of disintegrant addition into the orodispersible tablets formulation was found to show a marked difference in the disintegration, as well as other physical characteristics of the orodispersible tablets where the extragranular mode of addition showed better property, which caused the orodispersible tablets to disintegrate the fastest.

    OBJECTIVES: To promote a holistic approach to healthcare, the University of Cyberjaya introduced a unique elective course called sports pharmacy, which incorporates components of lifestyle interventions. Customers increasingly seek guidance about lifestyle factors that impact their health. Pharmacists with expertise in sports and exercise can meet this need. However, there is a lack of studies on the impact of non-pharmacological approaches (NPAs) on health parameters among healthcare professionals and pharmacy students in Malaysia. The objectives of this study were to compare students' health parameters based on NPAs and identify the factors that motivate students to maintain their health.

    MATERIALS AND METHODS: The study comprised 47 Year 4 pharmacy students in the pre- and post-practical phases (September 2018 and November 2018), followed by the post-resting phase (May 2019). The data collection form in the Sport Pharmacy course was used for the data collection.

    RESULTS: Nearly half of the students initially displayed a normal body mass index (BMI). However, after the post-resting period, there was a noticeable increase in the number of students categorized as obese and those with elevated total cholesterol (TC) and fasting blood glucose (FBG) levels. Specifically, in the pre-study phase, out of 47 participants, 22 were within the normal BMI (47%), six underweight (13%), nine overweight (19%), and ten obese (21%). The intervention phase showed a slight reduction in the overweight category, while the obese category showed an increase. For TC, the pre-phase had 70% of participants within the normal range, with 26% borderline high and 4% high. Post-study, showed an improvement, likely influenced by controlled dietary intake and physical activity. In the post-resting phase, however, there was a regression as the majority did not adhere to the non-pharmacological regimen. FBG demonstrated significant changes after the intervention, particularly within the normal range (≤ 6.0 mmol/L), showing the only statistically significant change across parameters. While the post-resting phase saw a minor increase, it remained below baseline. Approximately 23% continued diet control, while 32% maintained physical activity. Key motivations included health improvement, visible results, and improved well-being, while lack of motivation, time, and study schedules were primary discontinuation factors.

    CONCLUSION: The 10-week intervention significantly impacted FBG but had limited influence on BMI and TC. Post-resting outcomes highlight that only a small fraction maintained the non-pharmacological approach, resulting in no marked changes in any parameters. Recommendations include further long-term studies to confirm the sustained benefits and the role of educational institutions in supporting such interventions.

    Orally disintegrating tablets are a solid dosage form that will disintegrate rapidly within 3 minutes upon contact with saliva. Fillers or diluents are excipients that are used to make up the volume of orally disintegrating tablets, and some might act as a disintegrant or binder that will affect the physical properties of orally disintegrating tablets. The objective of this study was to formulate and evaluate physical properties of orally disintegrating tablets containing Annona muricata leaves extract by a freeze-drying method using different fillers at different concentrations. In this study, fifteen formulations of orally disintegrating tablets were prepared by a freeze-drying method with different fillers such as starch, lactose, microcrystalline cellulose, StarLac, and CombiLac at 5%, 10%, and 15%. The orally disintegrating tablets were evaluated for hardness, thickness, weight variation, friability, and disintegration time test. The optimum formulation was chosen and incorporated with Annona muricata leaves extract. The results obtained in this work indicated that Formulation 3, with 15% starch, was the most optimum formulation due to the shortest disintegration time (21.08 seconds ± 4.24 seconds), and all the physical tests were within the acceptable range. The orally disintegrating tablets containing Annona muricata leaves extract possessed antioxidant activity and stable at least for 3 months under 60°C and 75% relative humidity.
