This study evaluated the antioxidant activity as well as bioflavonoid content of the methanol and ethanol-water extracts of the fresh and dried leaves of Tetracarpidium conophorum. Antioxidant activity was determined by spectrophotometric methods using DPPH free radical, nitric oxide radical inhibition and ferric reducing antioxidant power assays. In addition, total phenolics, flavonoids and proanthocyanidin content were also determined. The ethanol: water extract of the dried leaves had the highest antioxidant activity with a 50% inhibition of DPPH at a concentration of 0.017 mg/mL compared to the standards, Vitamin C and Vitamin E with inhibition of 0.019 and 0.011 mg/mL, respectively. This extract also showed nitric oxide radical inhibition activity comparable to that of rutin, 54.45% and 55.03% for extract and rutin, respectively, at 0.1 mg/mL. Ferric reducing power was also comparable to that of ascorbic acid (281 and 287 μM Fe (11)/g, resp.) at a concentration of 1 mg/mL. The methanol extract of both the dried and the fresh leaves had higher phenolic, flavonoids and proanthocyanidin content than the ethanol : water extract. The study reveals that T. conophorum can be an interesting source of antioxidants with their potential use in different fields namely food, cosmetics and pharmaceuticals.

About 80% of the consumers worldwide use herbal medicine (HMs) or other natural products. The percentage may vary significantly (7%-55%) among pregnant women, depending upon social status, ethnicity, and cultural traditions. This manuscript discusses the most common HMs used by pregnant women, and the potential interactions of HMs with conventional drugs in some medical conditions that occur during pregnancy (e.g., hypertension, asthma, epilepsy). It also includes an examination of the characteristics of pregnant HM consumers, the primary conditions for which HMs are taken, and a discussion related to the potential toxicity of HMs taken during pregnancy. Many cultures have used HMs in pregnancy to improve wellbeing of the mother and/or baby, or to help decrease nausea and vomiting, treat infection, ease gastrointestinal problems, prepare for labor, induce labor, or ease labor pains. One of the reasons why pregnant women use HMs is an assumption that HMs are safer than conventional medicine. However, for pregnant women with pre-existing conditions like epilepsy and asthma, supplementation of conventional treatment with HMs may further complicate their care. The use of HMs is frequently not reported to healthcare professionals. Providers are often not questioning HM use, despite little being known about the HM safety and HM-drug interactions during pregnancy. This lack of knowledge on potential toxicity and the ability to interact with conventional treatments may impact both mother and fetus. There is a need for education of women and their healthcare professionals to move away from the idea of HMs not being harmful. Healthcare professionals need to question women on whether they use any HMs or natural products during pregnancy, especially when conventional treatment is less efficient and/or adverse events have occurred as herbaldrug interactions could be the reason for these observations. Additionally, more preclinical and clinical studies are needed to evaluate HM efficacy and toxicity.

Background Patients with chronic diseases exploit complementary and alternative treatment options to manage their conditions better and improve well-being. Objective To determine the prevalence and predictors of herbal medicine use among Type 2 Diabetes patients in Lagos, Nigeria. Setting Secondary healthcare facilities in Lagos state, Nigeria. Method The study design was a cross sectional survey. A two-stage sampling approach was used to select the health facilities and patients were recruited consecutively to attain the sample size. Data was collected using a structured and standardized interviewer-administered questionnaire. Characteristics, prevalence and predictors of herbal medicine use were assessed using descriptive statistics and multivariate regression analyses. Main outcome measure Herbal medicine use among Type 2 diabetes mellitus patients. Results 453 patients were surveyed, 305 (67.3%) reported herbal medicine use, among whom 108 (35.4%) used herbal and conventional medicines concurrently; 206 (67.5%) did not disclose use to their physician. Herbal medicine use was significantly associated with age (p = 0.045), educational level (p = 0.044), occupation (p = 0.013), duration of diabetes disease (p = 0.007), mode of diabetes management (p = 0.02), a positive history of diabetes (p = 0.011) and presence of diabetes complication (p = 0.033). Formulations or whole herbs of Vernonia amygdalina, Moringa oleifera, Ocimum gratissimum, Picralima nitida, and herbal mixtures were the commonest herbal medicine. Beliefs and perceptions about herbal medicine varied between the users and non-users. Conclusion The use of herbal medicine among Type 2 diabetes mellitus patients in Lagos, Nigeria is high. There is dire need for health care practitioners to frequently probe patients for herbal medicine use and be aware of their health behaviour and choices, with a view to manage the disease better.

Background: Concurrent use of herbal and orthodox medicines can result in herb-drug interaction, which could remain unidentified due to the limited knowledge of health care providers on herbal medicines effects and safety.Objectives: This study aimed to assess the knowledge of medical and pharmacy students of the University of Lagos on herbal medicines and herb-drug interactions.Method: The study was a cross-sectional survey of final year pharmacy and medical undergraduate students (422) of the University of Lagos. Data was collected using a validated, previously developed, and standardized self-administered questionnaire. Descriptive statistics was used to evaluate the students’ demographics, knowledge of herbal medicines and herb-drug interactions, types and uses of herbal medicines, while inferential statistics was employed to assess the association between the students’ demographics and their knowledge of herb-drug interactions. Statistical significance was set at P<0.05.Results: The response rate was 97%. The students (98.0%) knew that herbs can be used as medicines; common uses of herbal medicines reported by the students include malaria (11.4%), pain (24.6%), and fever (36.2%). There was no association between the students’ demographics and their knowledge about herbal medicine. Age was significantly associated with knowledge of herb-drug interaction (P<0.05). The students (96.8%) knew that herbs can interact with conventional drugs when administered concurrently. The sources of the students’ knowledge about herbal medicine and herb-drug interaction include lectures (52.2%), literature (14%) and personal experience (13.9%).Conclusion: The students had good knowledge of herbal medicines; however, the subject of herbal medicines and their effects should be given more attention in the medical and pharmacy program curriculum, in order to enhance the students’ knowledge base of herbal medicines and interactions, and equip the future physicians and pharmacists adequately for better patient care. Keywords: Herbal medicines, Herb-drug interaction, Pharmacy students, Medical students

Introduction. Successful interventions for substance use disorders (SUDs), though obtainable, are not effectively utilized due to the high cost of treatment. The adoption of any given therapy is often impeded by insufficient evidence of the effectiveness of such treatment. Objective. This study aimed to assess the direct medical cost of treating SUD in two tertiary hospitals in South-West, Nigeria. Methods. A descriptive, cross-sectional survey of patients managed for SUD at the two psychiatric hospitals was carried out between January and June 2020. The inclusion criteria were patients with SUD above 18 years of age, registered and managed at the two hospitals. Data were collected from selected patients' case notes using a standardized data collection tool and analyzed using descriptive and inferential statistics. Results. The average costs of treatment for alcohol use disorder, drug use disorder, and drug and alcohol use disorder were ₦146,425.38 ± 57,388.84, ₦135,282.09 ± 53,190.39, and ₦143,877.33 ± 68,662.04, respectively. This translates to $384.82, $355.53, and $378.12, respectively. The highest contributors to SUD treatment cost are inpatient admissions and the cost of medicines; inpatient admissions include accommodation, feeding, and laundry. Conclusion. Considering that over 60% of the Nigerian population lives below the poverty line, the direct cost of SUD treatment is unaffordable to the patients and the health care system, which is grossly underfunded.

Background: Extemporaneous compounding is a vital part of pharmaceutical care and could help community pharmacists personalize patients' treatment and improve treatment outcomes. Objectives: To assess the knowledge, attitudes, and practice about extemporaneous compounding among community pharmacists in Lagos, Nigeria. Methods: A cross-sectional survey of community pharmacists across the various zones of the Lagos State chapter of the Association of Community Pharmacists of Nigeria was conducted from July to September 2021. Data were collected using a validated online questionnaire and analyzed using descriptive and inferential statistics. Ethical approval was obtained prior to commencement of the study. Results: A total of 255 community pharmacists (CPs) participated in the survey. Almost all (98.4 %) had good knowledge of extemporaneous compounding in multiple domains, and most (84.3%) had positive attitudes towards compounding. However, only 20 (7.8%) CPs carried out one form of compounding or the other in their premises. The most significant driver of extemporaneous compounding was the need to avoid an allergy to an ingredient in a commercially available medication (94.9%), while the most significant barrier was the lack of prescriptions requiring compounding (95.3%). Conclusion: Community Pharmacists in Lagos State had good knowledge and a positive attitude toward extemporaneous compounding, but the practice was low. Collaborative efforts of relevant stakeholders in pharmacy practice are required to address the identified barriers to extemporaneous compounding.
