Hypertension is a prevalent chronic disease, which is strongly related to the development of cerebrovascular and cardiovascular diseases. The prevalence of hypertension in Malaysia in subjects aged 15 years and above was estimated to be 27.8%. Cost-effectiveness analysis (CEA) compares treatment options with different effectiveness and safety profiles. The utilisation of antihypertensive drugs has raised some concerns about the balance between its costs and benefits. This study was conducted to describe the healthcare costs for hypertensive subjects and to examine the cost-effectiveness of different classes of antihypertensive drugs used in Malaysia. Retrospective and prospective data analysis of a cohort of uncomplicated hypertensive patients was conducted to determine ambulatory health care costs among hypertensive patients groups. The total direct and
indirect costs of controlled and uncontrolled blood pressure (BP) were described. The health care
costs ($) / clinical outcome (AC/E ratio) was calculated. Mean total direct costs per patient per month was higher in uncontrolled blood pressure groups compared to the controlled blood pressure groups. The cost-effectiveness relationship was more favourable for diuretics (1.9), angiotensin converting enzyme inhibitors (ACEIs) (2.0), prazosin (2.4) and beta blockers (2.5), more than the diuretics and beta blockers combination theraphy (3.0), calcium channel blockers (CCBs) (3.4) and other combinations (6.1). Antihypertensive drugs used to treat hypertensive patients were different
in their cost-effectiveness ratios. Such results will allow health care professionals and/or decision
makers to make better decisions on how to select treatment options for hypertensive patients in
Malaysia and how to distribute and allocate scarce health care resources. Pharmacoeconomic
evaluations can help in making difficult choices rationally and allocate scarce resources efficiently.
An assessment on the use of acetaminophen (paracetamol) among consumers would
provide guidance for implementing strategies to overcome the misuse of acetaminophencontaining
products. This study aims to evaluate Malaysian consumers’ practices,
perceptions and understanding regarding the use of acetaminophen. A semi-structured
qualitative study utilising face-to-face interviews was conducted among 14 consumers
aged 24 to 82 years old who live in Pulau Pinang, Malaysia. Transcripts of all the
interviews were generated from audio tapes and were analysed for the issues and themes
emerging from the text; the transcripts were independently coded and verified by experts.
The consumers had a positive attitude towards the popularity, safety and efficacy of
acetaminophen. The consumers predominantly used acetaminophen for pain and fever.
Some consumers tended to increase the frequency and dosage of acetaminophen
consumption if their condition persisted. Consumers had difficulty recognising the generic
acetaminophen-containing products available in the market. Health literacy investigations
have found that consumers have a lack of knowledge regarding the correct dosing
regimen for acetaminophen in adults and children. The consumers were not aware of the
precautions and toxicities of acetaminophen. To increase awareness of acetaminophen
poisoning in Malaysia, the consumers suggested that educational tools regarding the
proper use of acetaminophen are needed from the Ministry of Health and policy-makers.
The information gained from this study emphasises the importance of educational
interventions to educate the public on the proper use of acetaminophen in Malaysia.
Phenytoin follows Michaelis-Menten, a non-linear pharmacokinetics that occurs when drug molecules saturates the enzymes ability to metabolise the drug. When this occurs, steady state phenytoin serum concentration increases in a disproportionate manner after a dosage increase. General population data are usually used for the phenytoin dose calculation. However, many studies show that population pharmacokinetic parameters of phenytoin have high variations. Thus, use of specific local pharmacokinetic parameters for each population group in estimating individualised phenytoin dose can reduce phenytoin toxicity cases. This prospective, observational study was conducted to estimate a local Vmax and Km of phenytoin for adult epileptic patients in neurological ward and clinic at Hospital Pulau Pinang, Malaysia. All therapeutic drug monitoring of oral capsule phenytoin were studied in a three-month data collection period. Out of the 17 subjects in our study, there are 13 male subjects (76.47%) and 4 female subjects (23.53%). A total 11 Malay subjects (64.71%), 4 Chinese subjects (23.53%) and 2 Indian subjects (11.76%) were included. Median Vmax and Km were found to be 8.25 mg/kg/day and 3.80 mg/l. Male subjects have a higher Vmax (8.30 mg/kg/day) but a lower Km (3.3 mg/l). Chinese population has the highest Vmax (8.80 mg/kg/day). For Km, Indian population is the highest, with a value of 5.5 mg/l. From our study, gender does not correlate with Vmax and Km of phenytoin (p-value > 0.05). Ethnicity was also found to have no association with Vmax and Km (p-value > 0.05). Local Vmax (8.25 mg/kg/day) is higher and Km (3.8 mg/l) is lower when compared with standard Vmax (7 mg/kg/day) and Km (4 mg/l) obtained from Caucasian population.
exhibits extensive first pass metabolism with poor oral bioavailability (27%–50%) limiting its therapeutic efficiency. The present study involved an attempt to enhance its aqueous solubility by formulating as solid dispersions (SDs) using sodium starch glycollate (SSG) as a carrier. The dispersions were formulated by dispersion method and evaluated by phase solubility, drug content, in vitro release and mathematical modelling. Solid state characterisation of samples was carried out by X-ray diffraction (XRD), differential scanning calorimetric (DSC), Fourier transform infrared spectrophotometry (FTIR), near infrared (NIR), Raman analysis and wettability studies. The phase solubility and thermodynamic parameters indicated the spontaneity and solubilisation effect of carrier. The release rate from the dispersions was higher than pure drug and found to increase with an increase in carrier content. The optimised dispersions were selected based on release studies, profiles and dissolution parameters. XRD, DSC, FTIR, NIR and Raman analysis proved the crystallinity reduction, changes in crystal quality and compatibility between drug and carriers. Wettability studies proved the increased wettability in selected dispersions. Based on the findings, possible mechanisms that would have contributed to dissolution enhancement of CLZ were suggested. Such findings could be extrapolated to enhance the aqueous solubility of other poorly water-soluble drugs.
Shared-decision making (SDM), occasionally called “participatory governance” is the approach in healthcare to ensure that patients have the right to participate effectively in the decision-making (DM) process. The aim of this research was to discuss the external aspect of SDM and put forward applicable solutions to ensure SDM at both patient and physician levels. A standardised validated nine-item SDM questionnaire (patient version SDM-Q-9) was employed. SPSS version 25 was used to perform data analysis. Multiple tests such as Mann-Whitney U and Jonckheere-Terpstra were used. Kendall’s Tau coefficient was used for interpretation of the significant relationship among all items of SDM-Q-9 and education. A total of 465 chronically ill patients took part, where majority (63.4%) of patients was above the age of 47. The cohort was dominated by females (67.5%) with 92% of the sample was married. Majority (86.9%) of the patient reported not involved in any decision. During analysis, considerable association was reported between gender and all items of SDM-Q-9, where more men were involved in SDM when compared with women. Our findings did produce significant association between education and SDM-Q-9, which reveals that increase in education can improve the SDM. SDM should not be limited to chronic or emergency in practice. Specific and tailored shared medical DM programmes must be developed for low literacy population implementation. SDM is to be supported at policy and operation levels.
