Knowledge of the Use of Herbal Medicines among Community Pharmacists and Reporting Their Adverse Drug Reactions

Pharmacy education in traditional and complementary medicines - A systematic review

BACKGROUND

Traditional and complementary medicines (T&CMs) are not typically covered in medical curricula despite 80% of the world's population using some form of herbal product as part of their healthcare. Concurrent use of T&CMs with conventional therapies is common, and both are primarily accessed in pharmacies. There is an expectation that pharmacists should be knowledgeable about T&CMs. Therefore, this review aimed to investigate what is currently known about pharmacists' T&CMs education and training to inform developments in pharmacy education.

METHODS

Eligible studies published between 01/01/2016 and 28/02/2023 were identified across six databases (PubMed, Scopus, Web of Science, EMBASE, ScienceDirect and MEDLINE). Data were extracted from included studies and categorized into key themes and sub-themes and reported descriptively.

FINDINGS

Fifty-eight studies were identified, conducted across 30 countries, that included information about pharmacists' T&CMs education and training. Within the four main themes extracted, six subthemes were identified including: T&CMs education and training received; inadequate education and training opportunities; knowledge, and confidence towards T&CMs in the pharmacy setting; professional practice behaviour associated with T&CM; university education for pharmacy students; and continuing professional development for practicing pharmacists, including T&CM-drug interactions, interpreting T&CM research, T&CM-specific communication skills, T&CM use in pregnancy and breastfeeding, and efficacy and safety of T&CM in specific conditions.

CONCLUSION

Overall pharmacists are receiving limited T&CM education in undergraduate and continuing professional training and report a lack of resources to inform the advice they provide to consumers. The findings of this review can inform developments in T&CMs curriculum and accreditation standards that support the training needs of pharmacists who play a role in fostering the safe and appropriate use of these products.

Herbal supplements in Jordan: a cross-sectional survey of pharmacists' perspectives and knowledge

OBJECTIVES

Pharmacists are ideal partners for engaging with the needs and expectations of patients. They can play a vital role by providing information and supplying herbal medicines. In some community settings, pharmacists are also the main first point of care. This study explored Jordanian community pharmacists' perspectives and knowledge of herbal medicines available in pharmacies.

DESIGN

A cross-sectional study using an online survey was developed, and it was distributed via social media platforms. The one-way analysis of variance (ANOVA) test was used to compare the mean knowledge scores between different demographic groups. Multiple linear regression analysis was used to identify predictors of herbal medicines knowledge.

SETTING

Jordanian community pharmacies.

PARTICIPANTS

401 Jordanian community pharmacists.

RESULTS

Herbal supplements are sold in practically all pharmacies (98.5%). Slimming aids (14.7%), followed by sexual and sports enhancements (14%) and maintaining general health (12.1%) were most requested by Jordanian customers. While supplements for maintaining general health (12%), followed by slimming aids (11.4%) and skin conditions (9.3%) were most recommended by Jordanian pharmacists. 63.1% were not aware of potential herb-drug interactions, 95.6% did not receive complaints from customers about herbal medicines and 41.2% would not report adverse reactions to the national pharmacovigilance services. The mean knowledge score for knowledge of use, regulation, adverse reactions, and drug interactions was 3.7 (SD: 0.7), 3.5 (SD: 0.8), 3.6 (SD: 0.8), and 3.6 (SD: 0.8) (out of 5), respectively. ANOVA test showed that total pharmacists' knowledge scores significantly differed based on the length of time practising pharmacy (p<0.05).

CONCLUSION

This study highlights some key concerns relating to recommendations, awareness and reporting of herbal medicines among Jordanian community pharmacists. Pharmacists need enhanced education to provide objective and evidence-based information on the benefits-risks of herbal medicines. Future studies need to be carried out to confirm whether our findings are transferable to other Middle Eastern countries.

A systematic review of community pharmacist practices in complementary medicine

Background

The people who use complementary medicines (CMs) believe that these medicines are safe and harmless. They could easily access CMs like herbal or traditional medicines in community pharmacies. Therefore, community pharmacists are important professionals in advising the safe choices of CMs and providing evidence-based information for customers to decrease adverse effects of CMs.

Objectives

To systematically review knowledge, attitude, and practices of community pharmacists about CMs, and the factors associated with CM practices of dispensing, recommending and counseling patients, and answering the patients' queries.

Method

An electronic search was performed with four databases: PubMed, Scopus, SpringerLink and ScienceDirect, from 1990 to 19th May 2022. The inclusion criteria were studies 1) about knowledge, attitude, and/or practices of community pharmacists about CMs, 2) written in English, 3) conducted with quantitative methods, and 4) able to retrieve full text.

Results

Twenty-three studies were included in this systematic review. Some studies showed that less than half of the pharmacists asked or counselled about CMs to their patients and answered the patients' queries about CMs. Only 20% of the pharmacists did report CM side-effects. Training or education about CMs was a common factor associated with the CM practice of dispensing, recommending, counseling, and answering the patients' queries about CMs. CMs recommended most by community pharmacists were vitamins & minerals, food or dietary supplements, fish oil and probiotics. The most common dispensed CMs were vitamins & minerals, herbs, food or dietary supplements, fish oil and essential oils. Lacks of reliable information sources and scientific evidence were common barriers for the CM practices. Being less expensive than conventional medicines motivated the pharmacists to recommend and discuss about CMs. The community pharmacists that participated in included studies suggested strengthening CM trainings and highlight the pharmacist role in CM therapy.

Conclusion

A high percentage of community pharmacists did dispense CMs to their patients, while a low percentage of the pharmacists did report CM side effects. Pharmacists were most comfortable recommending and responding the patients' CM queries. Training or education about CMs associated with CM dispensing, recommending, discussing, and answering the patients' queries about CMs was recommended.
