    This report stresses on the occurrence of a rare adverse reaction to clozapine, i.e. allergic cutaneous and visceral angioedema, in a patient with treatment resistant schizophrenia (TRS). We report the case of a schizophrenic patient who was resistant to treatment and developed an allergic reaction involving her skin and gastro-intestinal system upon the commencement of clozapine. She was then treated with a combination pharmacotherapy which left some residual symptoms. The manifestation of allergic reactions to clozapine and its management strategies are discussed in the paper. There is a pressing need to develop a new psychotropic which is on par with clozapine.

    The safety and efficacy of drugs may be different in children compared to adults. The available documentation at the time of approval for drug use in humans invariably lack data for use in children as generally children are not exposed to medicines in clinical trials. As such, in order to clarify a safety profile in children and to limit the occurrence of adverse drug reactions (ADR), long term data collection is necessary. There is a need to consider how pharmacovigilance is conducted for medicines used by children. It is the ethical responsibility of all health professionals to report ADR. Currently, ADRs in children does not appear to be at a critical level. Certainly, a high standard of care could be a reason but the possibility of health professionals underreporting ADRs has to be considered. Furthermore, many drugs used in children are not licensed for use in this age group. This may further limit the reporting of suspected ADRs to the pharmacovigilance systems.

    The clinical suspicion of onychomyosis based on appearance of the nails, requires culture for confirmation. This is because treatment requires prolonged use of systemic agents which may cause side effects. One of the common problems encountered is improper nail sampling technique which results in loss of essential information. The unfamiliar terminologies used in reporting culture results may intimidate physicians resulting in misinterpretation and hamper treatment decision. This article provides a simple guide on nail sampling technique and the interpretation of culture results.

    No screening test is ideal for detecting rheumatic diseases; diagnosis depends on appropriate history and thorough physical examination. Sometimes, laboratory investigations may be useful in confirming or ruling out rheumatic disease after a clinical diagnosis is considered. Once a rheumatic disease has been diagnosed, certain laboratory tests can help in assessing prognosis or determining the extent of the disease. Laboratory tests may also help the physician monitor certain rheumatic diseases, guide treatment or assess potential drug toxicity.

    Diuretics have a long and distinguished history in the treatment of hypertension and heart failure. Clinical practice guidelines recommend that diuretics should be considered to be as suitable as other antihypertensive agents for the initiation and maintenance of antihypertensive treatment. However, diuretics may potentially cause electrolyte disturbances and metabolic side effects. Diuretic-induced hyponatremia is probably more prevalent than generally acknowledged. We present an unusual case of indapamide-induced hyponatremia and hypokalemia complicated by cardiac arrhythmia. The adverse drug reaction was reversible and non-life-threatening, but this case serves as a reminder that careful evaluation and constant monitoring are necessary when prescribing diuretics.

    Introduction: The geriatric population in Malaysia is expanding rapidly due to increased life expectancies. The vulnerability of this population to the adverse effects of medications due to multiple comorbidities and polypharmacy predisposes them to potentially inappropriate medications (PIMSs). The Beers Criteria is a recognized tool for assessing PIMs, but the level of awareness regarding these criteria among community pharmacists is currently unknown.
    This study aimed to assess the awareness and knowledge of Beers Criteria and its extent of application in practice among community pharmacists in the Klang Valley, Malaysia. Methods: A cross-sectional study was conducted among 218 community pharmacists in the Klang Valley using a validated, self-administered questionnaire. Knowledge on PIMs was assessed using a ten-question clinical vignette based on Beers Criteria. Descriptive and inferential statistics were used to analyze the data. Results: Respondents had a significant proportion of their customer base who were elderly. Only 28% of respondents were aware of Beers Criteria, and of this group only 41% were aware of the latest update. The mean score for the clinical vignette was 5.42 ± 1.98. Awareness of Beers Criteria and years of experience in practice were associated with higher knowledge scores (p < 0.05). Good geriatric practices were reported by respondents with the exception of regular usage of Beers Criteria (16.5% agreement) and regularly asking
    elderly-looking customers their age (43.6% agreement). Most respondents (74.3%) utilized other clinical resources and were confident in providing care to elderly customers. Conclusion: Awareness of Beers Criteria remains low among community pharmacists. However, pharmacists utilized other resources and demonstrated good geriatric practices. While this shows the adequacy of current practice, efforts to increase awareness of geriatric-specific tools such as Beers Criteria may address specific knowledge gaps and improve the level of care involving the elderly.

    The delivery of safe and effective radical cure for Plasmodium vivax is one of the greatest challenges for achieving malaria elimination from the Asia-Pacific by 2030. During the annual meeting of the Asia Pacific Malaria Elimination Network Vivax Working Group in October 2016, a round table discussion was held to discuss the programmatic issues hindering the widespread use of primaquine (PQ) radical cure. Participants included 73 representatives from 16 partner countries and 33 institutional partners and other research institutes. In this meeting report, the key discussion points are presented and grouped into five themes: (i) current barriers for glucose-6-phosphate deficiency (G6PD) testing prior to PQ radical cure, (ii) necessary properties of G6PD tests for wide scale deployment, (iii) the promotion of G6PD testing, (iv) improving adherence to PQ regimens and (v) the challenges for future tafenoquine (TQ) roll out. Robust point of care (PoC) G6PD tests are needed, which are suitable and cost-effective for clinical settings with limited infrastructure. An affordable and competitive test price is needed, accompanied by sustainable funding for the product with appropriate training of healthcare staff, and robust quality control and assurance processes. In the absence of quantitative PoC G6PD tests, G6PD status can be gauged with qualitative diagnostics, however none of the available tests is currently sensitive enough to guide TQ treatment. TQ introduction will require overcoming additional challenges including the management of severely and intermediately G6PD deficient individuals. Robust strategies are needed to ensure that effective treatment practices can be deployed widely, and these should ensure that the caveats are outweighed by  the benefits of radical cure for both the patients and the community. Widespread access to quality controlled G6PD testing will be critical.

    Proton pump inhibitors (PPIs) are the mainstay of therapy for all gastric acid related diseases and are commonly used in current clinical practice. Although widely regarded as safe, PPIs have been associated with a variety of adverse effects, including hypomagnesaemia. The postulated mechanism of PPI-related hypomagnesaemia involves inhibition of intestinal magnesium absorption via transient receptor potential melastin (TRPM) 6 and 7 cation channels. PPIinduced hypomagnesaemia (PPIH) has become a well recognized phenomenon since it was first reported in 2006. Clinical concerns arise from growing number of case reports presenting PPIH as a consequence of long-term PPI use, with more than 30 cases published to date. In this article, we report 2 cases of PPIH associated with the use of pantoprazole. Both patients presented with severe hypomagnesaemia and hypocalcaemia. One of them had associated hypokalemia and cardiac arrhythmia. A casual relation with PPIs postulated and supported by resolution of electrolyte abnormalities after discontinuation of PPIs.

    Introduction: Community pharmacist's knowledge about the uses of herbal medicines and its adverse drug reactions reporting can contribute in better therapeutic outcomes and patient safety. Objectives: To evaluate community pharmacists' knowledge about the use of herbal medicines and its adverse drug reactions reporting in Kedah state, Malaysia.

    Methods: A cross-sectional, questionnaire-based study was conducted among 103 pharmacists from 74 different community pharmacies to assess their knowledge about the use of herbal medicines and its adverse drug reaction reporting by using a pre-validate knowledge questionnaire consisting of 12 questions related to it. The pharmacists' responses were measured at a 3-point Likert scale (Poor=1, Moderate=2, and Good=3) and data was entered in SPSS version 22. The minimum and maximum possible scores for knowledge questionnaires were 12 and 36 respectively. Quantitative data was analyzed by using One Way ANOVA and Paired t-test whereas Chi-square and Fisher exact test were used for qualitative data analysis. A p-value of less than 0.05 was considered statistically significant for all the analyses.

    Results: About 92% of the pharmacist had good knowledge regarding the use of herbal medicines and its adverse drug reaction reporting with a mean knowledge score of 32.88±3.16. One-way ANOVA determined a significant difference of employment setting (p<0.043) and years of experience (<0.008) with mean knowledge scores of Pharmacists. Pharmacists' knowledge was significantly associated with their years of experience with the Chi-square test.

    Conclusion: Pharmacists exhibit good knowledge regarding the use of herbal medicines and its adverse drug reaction reporting. However, with an increasing trend of herbal medicine use and its adverse drug reaction reporting it recalls the empowerment of experienced pharmacists with training programs in this area for better clinical outcomes.

    Hydrocortisone (HC) is a topical glucocorticoid for the treatment of atopic dermatitis (AD); the local as well as systemic side effects limit its use. Hydroxytyrosol (HT) is a polyphenol present in olive oil that has strong antimicrobial and antioxidant activities. HC-HT coloaded chitosan nanoparticles (HC-HT CSNPs) were therefore developed to improve the efficacy against AD. In this study, HC-HT CSNPs of 235 ± 9 nm in size and with zeta potential +39.2 ± 1.6 mV were incorporated into aqueous cream (vehicle) and investigated for acute dermal toxicity, dermal irritation, and repeated dose toxicity using albino Wistar rats. HC-HT CSNPs exhibited LD50 > 125 mg/body surface area of active, which is 100-fold higher than the normal human dose of HC. Compared with the commercial formulation, 0.5 g of HC-HT CSNPs did not cause skin irritation, as measured by Tewameter®, Mexameter®, and as observed visually. Moreover, no-observed-adverse-effect level was observed with respect to body weight, organ weight, feed consumption, blood hematological and biochemical, urinalysis, and histopathological parameters at a dose of 1000 mg/body surface area per day of HC-HT CSNPs for 28 days. This in vivo study demonstrated that nanoencapsulation significantly reduced the toxic effects of HC and this should allow further clinical investigations.

    Background: Potentially inappropriate prescribing (PIP) is associated with the incidence of adverse drug reactions, drug-related hospitalization and other negative outcomes in older adults. After hospitalization, older adults might be discharged with several types of PIPs. Studies have found that the lack of healthcare professionals' (HCPs) knowledge regarding PIP is one of the major contributing factors in this issue. The purpose of this study is to investigate the impact of a multifaceted intervention on physicians' and clinical pharmacists' behavior regarding potentially inappropriate medication (PIM) and potential prescribing omission (PPO) among hospitalized older adults.

    Methods: This is a before-and-after study that took place in a tertiary Malaysian hospital. Discharge medications of patients ≥65 years old were reviewed to identify PIMs/PPOs using version 2 of the STOPP/START criteria. The prevalence and pattern of PIM/PPO before and after the intervention were compared. The intervention targeted the physicians and clinical pharmacists and it consisted of academic detailing and a newly developed smartphone application (app).

    Results: The study involved 240 patients before (control group) and 240 patients after the intervention. The prevalence of PIM was 22% and 27% before and after the intervention, respectively (P = 0.213). The prevalence of PPO in the intervention group was significantly lower than that in the control group (42% Vs. 53.3%); P = 0.014. This difference remained statistically significant after controlling for other variables (P = 0.015). The intervention was effective in reducing the two most common PPOs; the omission of vitamin D supplements in patients with a history of falls (P = 0.001) and the omission of angiotensin converting enzyme inhibitor in patients with coronary artery disease (P = 0.03).

    Conclusions: The smartphone app coupled with academic detailing was effective in reducing the prevalence of PPO at discharge. However, it did not significantly affect the prevalence or pattern of PIM.

    BACKGROUND: Spontaneous reporting of adverse drug reactions (ADRs) is a method of monitoring the safety of drugs and is the basic strategy for the post-marketing surveillance of the suspected drugs. Despite its importance, there is very little reporting of ADRs by healthcare professionals. The present study has evaluated the knowledge, attitude and practices of health care professionals (HCPs) regarding pharmacovigilance activities in Lahore, Pakistan.

    METHODS: A cross-sectional questionnaire-based survey was employed, and a convenience sampling was opted to collect the data among physicians, pharmacists and nurses working in tertiary care public hospitals of Lahore, Pakistan from September 2018 to January 2019.

    RESULTS: Of the 384 questionnaires distributed, 346 health care professionals responded to the questionnaire (90.10% response rate). Most participants had good knowledge about ADR reporting, but pharmacist had comparatively better knowledge than other HCPs regarding ADR (89.18%) pharmacovigilance system (81.08%), its centres (72.97%) and function (91.89%). Most of the participants exhibited positive attitude regarding ADR reporting, such as 49.1% of physicians (P

    Background: Medication safety is a major public health concern and there are well established pharmacovigilance programmes in developed countries. However, there is scarcity of literature on the issue in low and middle income countries. In this context, the current study was aimed to evaluate the knowledge, attitudes and practices of hospital pharmacists towards medication safety and ADR reporting in Lahore, Pakistan.

    Methods: A qualitative approach was used to conduct this study. A semi-structured interview guide was developed, 10 hospital pharmacists were recruited and interviewed through convenience sampling technique. All interviews were audio-taped, transcribed verbatim, and were then analyzed for thematic contents analysis.

    Results: Thematic content analysis of the interviews resulted in 6 major themes, including (1) Familiarity with medication safety & adverse drug reaction concept (2) Current system of practice and reporting of adverse drug reaction in hospital setting, (3) Willingness to accept the practice change (4) Barriers to adverse drug reaction reporting, (5) Policy change needs and (6) The recognition of the role. Majority of the hospital pharmacists were familiar with the concept of medication safety and ADR reactions reporting however they were unaware of the existence of national ADR reporting system in Pakistan. Several barriers hindering ADR reporting were identified including lack of awareness and training, communication gap between the hospitals and regulatory authorities.

    Conclusion: The study revealed that that hospital pharmacists were good in understanding of medication safety and ADR reporting; however they don't practice this in real sense. The readiness of the hospital pharmacist towards the practice change has indicated that they are all set to be actively involved in the provision of medication safety in hospital setting. Involvement of key stake holders from ministry of health, academia, pharmaceutical industry and healthcare professionals is warranted to promote safe and effective use of medicines.
