OBJECTIVES: This study examined community pharmacists' beliefs towards risk minimization measures in off-label drug use in Malaysia and assessed the relationship between perceived risk of off-label drug use and beliefs towards risk minimization measures.

METHODS: A cross-sectional survey was conducted among 154 pharmacists practicing in randomly selected community pharmacies in Kuala Lumpur and the State of Selangor, Malaysia.

RESULTS: The majority agreed or strongly agreed that adverse drug events from the off-label drug should be reported to the regulatory authority (90.9%) and the off-label drug should only be used when the benefit outweighs potential risks (88.3%). Less than half (48.1%) agreed or strongly agreed that written informed consent should be obtained before dispensing off-label drugs and a majority (63.7%) agreed or strongly agreed that the informed consent process will be burdensome to healthcare professionals. Beliefs towards risk minimization measures were significantly associated with perceived risk of off-label drug use regarding efficacy (p = 0. 033), safety (p = 0.001), adverse drug rection (p = 0.001) and medication errors (p = 0.002).

AIM: This study aimed to examine the rate of compliance towards the requirements of LDM among retail pharmacies (RPs) and private medical clinics (PMCs).

METHODS: A cross-sectional study was conducted from April 2019 to January 2020 across all inspected premises in Sarawak. Publics who attended RPs and PMCs and having medicines dispensed, have their medicine labels examined for compliance towards the requirements of LDM upon exiting the premises. Their verbal consents were obtained and the compliance score were recorded into self-developed data collection forms. Compliance rate was the percentage of requirements on the examined medicine labels that fulfil the requirements under Regulation 12 of Poisons Regulations 1952.

RESULTS: A total of 414 LDM were examined, with 135 from RPs and 279 from PMCs. The full compliance towards the requirements of LDM among RPs and PMCs were 23.7% and 41.6%, respectively. The median compliance score of PMCs (0.83) was significantly higher (P<0.001) than RPs (0.67). The requirements of LDM with the lowest compliance was name of medicine (53.1%), followed by name of patient (31.9%) and date of dispensing (25.6%).

OBJECTIVE: To explore the knowledge, perception, and practices of community pharmacists (CP) and general practitioners (GP) on LDM.

METHODS: A cross-sectional study was conducted from April 2019 until March 2020 among CP and GP practising in Sarawak, Malaysia. Sample sizes were 90 and 150 for CP and GP, respectively. A self-administered structured questionnaire which was pre-tested and pilot-tested was employed to explore the knowledge and perception. Practices were assessed by having participants prepare dispensed medicine labels (DML) using simulated patients and prescriptions.

RESULTS: 250 participants; 96 CP and 154 GP participated. While most of them perceived that they know the requirements of LDM (n=244; 97.6%), their median knowledge score was poor (57.1%). The median knowledge score of CP (66.7%) was significantly higher (P=0.004) than GP (50.0%). The majority of participants perceived that LDM is important (n= 237; 94.8%) and necessary (n=239; 95.6%%) and perceived that poor compliance to the requirements would lead to medication errors (n=243; 97.2%). Although their knowledge was poor, their median practice score (100.0%) was excellent. There was no correlation between knowledge and perception with the practice on LDM.

METHOD: We aim to review published articles related to the side effects of long-term methadone therapy, focusing on hematological derangements in human studies published between 1 January 2000 till 31 January 2021.

RESULTS: Our search databases include Web of Science, Scopus, and Medline. Our search yielded 971 articles, of which 55 articles were related to the effects of MMT on various organ systems: cardiovascular [n=12], respiratory [n=1], endocrine [n=10], central nervous system [n=12], neurobehavioral [n=10], gastrointestinal [n=1], and bone [n=1]. There were eight articles specifically related to the hematological side effects of chronic methadone therapy that include [i] immune system hyperactivation, [ii] reduced circulating lymphocytes, and [iii] increased blood viscosity.

OBJECTIVE: This study aimed to thoroughly assess the ADRs associated with these drugs by utilizing the Adverse Event Reporting System (FAERS) database of the Food and Drug Administration (FDA).

METHODS: ADR reports for Paxlovid, Molnupiravir, and Remdesivir throughout the period of January 2022 to May 2023 were extracted and classified according to the severity, type of reaction, and demographic variables. Reporting Odds Ratios (RORs) with 95% confidence intervals were calculated to evaluate the relationship between antiviral medications and various ADRs.

RESULTS: The study established notable correlations between Paxlovid and the recurrence of the disease (40.08%) and dysgeusia (16.29%). Molnupiravir was linked to gastrointestinal (16.73%) and skin reactions (9.47%), while Remdesivir had impairments in the liver (25.21%) and kidneys (13.34%). ADRs were more commonly observed in female patients treated with Paxlovid (57.95%) and Molnupiravir (49.40%), whereas Remdesivir ADRs were mostly reported in males (58.56%). Paxlovid and Remdesivir ADRs were frequently reported in adults between the ages of 18 and 64 (46.01% and 45.01%), while Molnupiravir ADRs were more common in older individuals aged 65 to 85 (40.38%).
