ABSTRACT
@#Oral route drug delivery system is still considered as the most convenient and patient friendly drug delivery route. Over the decades, many research has been performed to improve the functionality oral dosage form. Orally disintegrating film (ODF) is a newer oral drug delivery system, which is in the form of a thin film that will disintegrate in the oral cavity within a matter of seconds. The aim of this review paper is to recap ODF, its benefits, formulation contents and manufacturing method. With more research and development work has been conducted on ODF, the dosage form is expected to be manufactured and scaled up to be commercializable products to be sold in the market.
ABSTRACT
@#Introduction: Amlodipine besylate is a calcium channel blocker indicated for hypertension and angina. It is described as slightly soluble in water and due to its limited solubility, it may result in poor bioavailability. The aim of this study is to enhance the solubility of amlodipine besylate using solvent evaporation method and microemulsion technique and to compare the two methods. Method: Solid dispersions (SD) of amlodipine besylate were developed by employing solvent evaporation method. PEG6000 was the polymer of choice and different drug:polymer ratios were used. Evaluation of the prepared SDs include solubility studies, dissolution studies and scanning electron microscopy (SEM). As for the microemulsion technique, microemulsions were prepared by phase titration method and the optimized microemulsion formulation was then characterized for solubility studies and dissolution studies. Results: SD3 with drug:polymer ratio of 1:4 achieved the highest solubility which was 96.97 mg/ml ± 0.92 whereas the solubility of the optimized microemulsion was found to be 112.54 mg/ml ± 0.92. In solvent evaporation method, as the drug:polymer ratio increases, the solubility and dissolution rate of SDs increases. Conclusion: The two methods had significantly enhance the solubility of amlodipine besylate however the microemulsion technique showed better solubility profile.
ABSTRACT
@#Introduction: Early environmental factors play a major role in shaping the health of an individual. Dietary preference and habits shaped by parental feeding practice during childhood are likely to persist into adulthood which further determines body weights status. This study aimed to determine the retrospective child feeding practices associated with obesity risk in young adults. Methods: This was a retrospective cross-sectional study with 176 university students in Kuala Lumpur. Data of maternal age, gestational age and feeding practices were collected retrospectively using Child Feeding Questionnaire (CFQ). Subject’s current socio-demographic data was collected and anthropometric measurements were taken using standard protocol. Results: Around 22% of the subjects were overweight/ obese. No significant association was found between child feeding practices with maternal age. A significant association (p<0.05) was found between pressure to eat with gestational age, in which parent with preterm (<37 weeks gestation) and full-term subjects were more likely to pressure their child to eat as compared to post-term subjects (>42 weeks gestation). Obesity risk in young adults was higher among parents who viewed themselves as overweight (aOR=2.783; CI=1.631-4.749) and who viewed their child as overweight from birth to primary school (aOR= 1.512; CI=1.080-2.116). Young adults that were pressured by their parents to eat during childhood were less likely to be obese (aOR=0.785; CI=0.621-0.992). Conclusion: Parental influences on child feeding practices were linked to obesity risk in young adulthood. Parent education on child feeding practices is needed to maintain healthy weight status of their child from young to later life.
ABSTRACT
We reviewed the current human immunodeficiency virus (HIV) prevention education programmes in Singapore, discussed the challenges faced and proposed prevention education interventions for the future. Education programmes on HIV prevention have shown some success as seen by reduced visits to sex workers among the general adult population and a marked increase in condom use among brothel-based sex workers. However, we still face many challenges such as low awareness of HIV preventive strategies and high prevalence of HIV stigma in the general population. Voluntary HIV testing and condom use remain low among the priority groups such as men who have sex with men (MSM) and heterosexual men who buy sex. Casual sex has increased markedly from 1.1% in 1989 to 17.4% in 2007 among heterosexuals in Singapore, with the majority (84%) practising unprotected sex. Sex workers have moved from brothels to entertainment venues where sex work is mostly hidden with lack of access to sexually transmitted infections (STIs)/ HIV prevention education and treatment programmes. Education programmes promoting early voluntary testing is hampered because of poor access, high cost and stigma towards people living with HIV. It remains a challenge to promote abstinence and consistent condom use in casual and steady sexual relationships among heterosexuals and MSM. New ways to promote condom use by using a positive appeal about its pleasure enhancing effects rather than the traditional disease-oriented approach should be explored. Education programmes promoting early voluntary testing and acceptance of HIV-infected persons should be scaled up and integrated into the general preventive health services.
