Use of complementary and alternative therapies for the treatment of dysmenorrhea among undergraduate pharmacy students in Malaysia: a cross sectional study

Investigational drugs for the treatment of dysmenorrhea

INTRODUCTION

Dysmenorrhea is the most common cause of gynecological pain among women that has considerable impact on quality of life and psychosocial wellbeing. Non-steroidal anti-inflammatory drugs (NSAIDs) and hormonal therapies are most commonly used to treat dysmenorrhea. However, given these drugs are often associated with bothersome side effects and are less effective when there is an underlying cause contributing to dysmenorrhea (e.g. endometriosis), a patient-centered approach to managing dysmenorrhea is important. Various new drugs are currently being investigated for the treatment of primary and secondary dysmenorrhea.

AREAS COVERED

This review provides an updated overview on new therapeutic targets and investigational drugs for the treatment of primary and secondary dysmenorrhea. The authors describe the clinical development and implications of these drugs.

EXPERT OPINION

Among the investigative drugs discussed in this review, anti-inflammatories show the most promising results for the treatment of dysmenorrhea. However, given some trials have considerable methodological limitations, many drugs cannot be currently recommended. Research focused on understanding the mechanisms involved in menstruation and its associated symptoms will be important to identify new therapeutic targets for dysmenorrhea. Further robust clinical trials are required to better understand the efficacy and safety of investigational drugs for treating primary and secondary dysmenorrhea.

Assessment of prevalence, knowledge and health-related practices of dysmenorrhea among Malaysian women in Kuala Lumpur: a cross-sectional survey

BACKGROUND

Menstruation is a natural phenomenon considered an important indicator of women's health, reflecting their endocrine function. Women in low middle income countries face substantial menstrual hygiene management challenges. Data on the knowledge of dysmenorrhea and health-related practices among Malaysian women are scarce. The present study aimed to investigate the prevalence of dysmenorrhea among Malaysian women in Kuala Lumpur and its association with socio-demographic factors, knowledge level, and general practices.

METHOD

A cross-sectional study was carried out among Malaysian women in Kuala Lumpur. A total of 362 unmarried women, nulliparous and aged between 18 and 25 years old, were included in this study. Participants were conveniently recruited through online platforms as well as face to face using a self-administered questionnaire with five sections consisting of demographics, menstrual characteristics, Working ability, Location, Intensity, Days of pain, Dysmenorrhea (WaLIDD) score for diagnosing and assessing the severity of dysmenorrhea as well as an evaluation of respondents' general knowledge and practices towards dysmenorrhea. The collected data were analysed using the SPSS tool, a descriptive statistic was used to report demographic characteristics. Inferential statistics was used to report the differentiation, association, and correlations of the variables.

RESULTS

The prevalence of primary dysmenorrhea was 73.2%. It was found that the majority of the respondents had poor knowledge (60%) and poor practices (61.88%) of dysmenorrhea. The most common preventive practices among the respondents were using dietary supplements, and herbs, taking a rest and exercising. The findings also indicated that dysmenorrhea among the respondents was significantly associated with family history of dysmenorrhea (p = 0.002), monthly income (p = 0.001), and knowledge level (p = 0.001).

CONCLUSION

Dysmenorrhea has a high prevalence among women in Malaysia in Kula Lumpur driven by low knowledge and lack of evidence-based practices among these women. Thus, it is critical for Government and healthcare authorities to promote education related to women health among Malaysian women.

Insight into Dysmenorrhea Research from 1992 to 2022: A Bibliometric Analysis

Dysmenorrhea, classified as primary dysmenorrhea and secondary dysmenorrhea, is a common gynecological symptom that seriously affects female daily life. At present, studies on dysmenorrhea are numerous and complex. To better reflect the trend and innovative progress of dysmenorrhea-related research, this study screened papers on the Web of Science from January 1, 1992, to December 31, 2022. A total of 1012 papers were selected and analyzed for their affiliated countries, institutions, authors, keywords, etc. China is the country with the most academic output, Beijing University of Traditional Chinese Medicine is the most influential institution, and Yang Jie, from Chengdu University of Traditional Chinese Medicine, China, is the scholar with the most papers. We consider that the current research focus is on pathogenesis, treatment, epidemiology, and self-management. With increasing research on functional connectivity between dysmenorrhea and various brain regions, functional connectivity has gradually become the forefront of research. We hope our study can promote the further study of dysmenorrhea.

Efficacy of psychological interventions for dysmenorrhea: a meta-analysis

Dysmenorrhea is pelvic pain associated with menstruation and is one of the most common pain conditions among reproductive-age women. It is commonly treated with medications, complementary and alternative medicine, and self-management techniques. However, there is increased focus on psychological interventions which modify thoughts, beliefs, emotions, and behavioral responses to dysmenorrhea. This review examined the efficacy of psychological interventions on dysmenorrhea pain severity and interference. We conducted a systematic search of the literature using PsycINFO, PubMed, CINHAL, and Embase. A total of 22 studies were included; 21 examined within-group improvement (ie, within-group analysis) and 14 examined between-group improvement (ie, between-group analysis). Random-effects meta-analyses were conducted on pain severity and interference, with average effect sizes calculated using Hedges's g. Within-group analyses showed decreased pain severity and interference at post-treatment (g = 0.986 and 0.949, respectively) and first follow-up (g = 1.239 and 0.842, respectively). Between-group analyses showed decreased pain severity at post-treatment (g = 0.909) and decreased pain severity and interference at first follow-up (g = 0.964 and 0.884, respectively) compared to control groups. This review supports the efficacy of psychological interventions for dysmenorrhea, but conclusions are tempered by suboptimal methodological quality of the included studies and high heterogeneity across studies. Additional, rigorous research is needed to determine the clinical utility of psychological interventions for dysmenorrhea.

Ethnopharmacological Survey of Traditional Chinese Medicine Pharmacy Prescriptions for Dysmenorrhea

Chinese herbal medicines have long been used for the treatment of dysmenorrhea. The treatment experiences of traditional Chinese medicine (TCM) pharmacies passed down through generations have contributed to a wealth of prescriptions for dysmenorrhea that have achieved significant therapeutic effects in countless Taiwanese women. Therefore, surveying and analyzing these prescriptions may enable us to elucidate the core medication combinations used in TCM prescriptions for dysmenorrhea. In the present study, a field investigation was conducted on various TCM pharmacies in Taiwan. A total of 96 TCM pharmacies were sampled, and 99 prescriptions for dysmenorrhea containing 77 different medicinal materials were collected. Compositae (8%) was the most common botanical source of the medicinal materials, and the predominant TCM property and flavor of the materials were warm (45%) and sweet (73%), respectively. The blood-activating and stasis-dispelling effect (23%) and the qi-tonifying effect (23%) were the most prevalent traditional effects, and the modern pharmacological effects most commonly found in the materials were anti-inflammatory (73%), antitumor (59%), and analgesic (12%) effects. Network analysis of the 77 medicinal materials used in the prescriptions, which was performed using the Traditional Chinese Medicine Inheritance Support System, yielded seven core medicinal materials and the corresponding network diagram. The seven core medicinal materials ranked in order of relative frequency of citation (RFC) were Angelica sinensis (Oliv.) Diels (Dang Gui), Ligusticum chuanxiong Hort (Chuan Qiong), Rehmannia glutinosa Libosch (Di Huang), Paeonia lactiflora Pall (Bai Shao), Hedysarum polybotrys Hand.-Mazz (Hong Qi), Lycium chinense Mill (Gou Qi Zi), and Cinnamomum cassia (L.). J. Presl (Gui Zhi). A total of 58 combinations, each consisting of two to five of the seven medicinal materials and 107 association rules among the materials, were identified. This study provides a record of valuable knowledge on TCM pharmacy prescriptions for dysmenorrhea. The rich medicinal knowledge of TCM pharmacies in Taiwan is worthy of further exploration, and the results of this study can serve as a basis for future pharmacological research and the development of naturally derived medications for dysmenorrhea.
