BackgroundEvaluation of patient/client satisfaction with pharmacy services as a crucial part of the health services through appropriate studies is important. This will help identify specific areas of the service which need improvement in realizing high quality pharmacy services in general and enhance the positive changes in the current pharmaceutical services provision in Ethiopia. The current study aimed at assessing the level of client satisfaction with the services of the outpatient pharmacy of Gondar University Referral Hospital (GURH) in northwestern Ethiopia.MethodsAn institution-based cross-sectional study was conducted involving 400 clients who had prescriptions/orders filled at the outpatient pharmacy of the hospital during the period of 5th to 25th of November 2013. The data on the level of satisfaction of clients with the services of the outpatient pharmacy in the hospital was collected using a structured interview guide adopted from an instrument translated into Amharic and validated. The data collected was entered into and analyzed using Statistical Packages for Social Sciences (SPSS) version 16.ResultsThe overall mean score the respondents gave to satisfaction with the pharmaceutical services was 2.48 out of a maximum of 5.00 score. The mean scores for all the individual parameters rated were less than 3.00. Maximum mean scores were given for parameters asking about the promptness of prescription medication service (2.99), and professionalism of the pharmacy staff (2.96) with the lowest being scored for information given to clients about the storage of medication (1.25), and explanations of possible side effects (1.27). Clients who were served free of fee recorded significantly higher level of satisfaction than those who paid. Higher levels of satisfaction were also reported among illiterates, older adults and those with no job compared to those with higher education, merchants and government employees.ConclusionsThis study showed that the overall mean satisfaction level of clients of the outpatient pharmacy was low and it differed among different socio-demographic characteristics. Further research in to the reasons behind the low satisfaction should be done to provide appropriate solutions to improve the service.

PurposeThis study was aimed at assessing the extent of dispensing prescription-only medications without a prescription in community drug retail outlets (CDROs) of Addis Ababa, Ethiopia.MethodsA descriptive cross-sectional observational study design was used to sample 31 pharmacies, 25 drug stores, and two rural drug vendors from August 11, 2015, to October 21, 2015, through a simple random sampling method. A simulated-patient method of visit was implemented to collect data. Requests of six tracer prescription-only medicines (amoxicillin + clavulanic acid capsule, amitriptyline, captopril, glibenclamide [also known as glyburide], omeprazole capsule, and sildenafil citrate) and upper respiratory tract infection were selected as the simulated clinical scenario.ResultsAmoxicillin–clavulanic acid capsule was dispensed when requested in 87.93% of the dispensaries. All of the CDROs dispensed omeprazole upon request. Sildenafil citrate (Viagra) was in stock in 96.55% of the CDROs, all of which issued the requested number of tablets without asking why or for whom the drug was needed. Amitriptyline, captopril, and glibenclamide (glyburide) were dispensed in 84.48%, 89.65%, and 87.93% of CDROs upon the provision of an empty container. Antibiotics were obtained from 75.86% of CDROs for presentation of upper respiratory tract infection symptoms. Among the dispensed antibiotics, the most common was amoxicillin (93.18%), followed by amoxicillin–clavulanic acid capsule (72.72%), and azithromycin (50%). Only 4.5% of the dispensaries asked about drug allergies, and 15.9% of the CDROs informed the simulated patient about the possible side effects of the drugs.ConclusionThis study revealed a very high rate of dispensing of prescription-only medicines without a prescription. Antimicrobials and drugs for chronic diseases were obtained with ease from almost all of the randomly sampled CDROs. Putting good dispensing practice into effect and adhering to the existing national laws and regulations regarding the same are necessary. It is also necessary to adopt a strong and explicit line of action, especially toward the irrational use of antibiotics.

Aromatic heterocycles with basic nitrogen atoms as well as carboxylic acid derivatives are the dominating chemical space in the universe of drug-like molecules. These established and exceedingly evaluated structural motifs have to be combined with elements of diversity in order to chart less well-explored galaxies of chemical space and to be able to tackle seemingly undruggable targets. Flat scaffolds should be replaced by shapely molecular cores. In this context, it has been unheeded that phenyl rings in diaryl sulfides are less co-planar than in ethers and that the metabolic interconnection of sulfides and sulfoxides offers advantages that are unalike from the chemistry of amines and N-oxides in the CHN-O world. Moreover, σ-hole potentials increase with the polarizability of the atom N < P < O < S and do not only play a role in long-time overlooked halogen bonds. Examples for λ 2 , λ 4 , and λ 6 S-based functionalities related to improved solubility, reduced drug resistance, linkers in drug conjugates, drugtargeting to parasites, and as basis for drug monitoring in sports are given and discussed.

BackgroundHousehold surveys are crucial to get accurate information on how medicines are acquired, and used by consumers, as they provide the best evidence in the area. The objective of this study was to document household medicine storage practices in Gondar town, northwestern Ethiopia.MethodsA cross-sectional household survey was conducted from April 5 to May 6, 2015. In the study, 809 households were surveyed from four sub-cities in the town selected through multistage sampling with 771 included in the final analysis. Data on the extent of storage, storage conditions, sources of medicines and their current status among others were collected through structured interviews and observations. The data were entered in to Epidata version 3.1, exported to and analyzed using Statistical Packages for Social Sciences (SPSS) version 21.ResultsOf the 771 households in the study, 44.2% stored medicines. Presence of family members with chronic illness(es) and higher levels of household incomes predicted higher likelihood of medicine storage. In the households which allowed observation of stored medicines (n = 299), a mean of 1.85 [SD = 1.09] medicines per household were found. By category, anti-infectives for systemic use (23.9%), medicines for alimentary tract and metabolism (19.2%) and those for cardiovascular system (17.7%) ranked top. Among individual medicines stored, diclofenac (10.7%), paracetamol (9.9%) and amoxicillin (8.0%) were on top of the list. Dispensaries (97.8%) and physicians (83.5%) were almost exclusive sources of medicines and advices/orders for medicines respectively. Nearly two-thirds of the medicines found were on use and a vast majority (76.5%) were stored in chests of drawers. Proportion of expired medicines was very low (3.14%).ConclusionsThe use of physicians’ and pharmacists’ advice to get medicines; use of dispensaries as principal sources, large proportion of medicines being in use and very low proportion of expiry showed good practices. However, storage places of medicines were not purpose built. Encouraging good practices through continued medicine use education and advocating appropriate medicine storage in medicine cabinets is required to improve storage conditions and consequent use of medicines.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-017-4152-8) contains supplementary material, which is available to authorized users.

BackgroundHighly active antiretroviral therapy improves the longevity of patients living with HIV/AIDS. We conducted the study in order to assess health related quality of life of HIV/AIDS patients and the association of socio-demographic and disease related variables with health related quality of life.MethodsHealth facility based cross-sectional study among 400 HIV/AIDS patients taking highly active anti-retroviral therapy from Gondar University referral hospital was conducted. A pre-tested semi-structured questionnaire, which was adopted from World Health Organization Quality of life brief instrument, was used. The data were then analyzed using SPSS version 20 software for Windows.ResultsThe majority of the respondents reported to to have a good physical health (15.55). The World Health Organization clinical stage was found to be significantly associated with all the domains of health related quality of life. The current acute illness condition of the respondents, however, did not show significant association with any of the domains of health related quality of life.ConclusionsThe six domains of health related quality of life were found to be moderate. The physical health and spirituality of the patients were relatively higher than their social relationship. Sex, age, educational status, residence and marital status showed significant association with at least one domain of health related quality of life.

Background:Community pharmacists play a crucial role in reducing medication related health problems and improving the patient’s overall wellbeing. Evidence suggests that community pharmacist led counseling services result in a better clinical and self-reported outcome, including a higher level of satisfaction and quality of life.Objective:This study aims to document self-reported and actual levels of community pharmacists’ involvement in the provision of patient counseling and barriers that limit their involvement in such services.Methods:Simulated patient visits and a cross-sectional survey of community pharmacists were employed in Gondar town, Ethiopia between March 15 and May 15, 2016 to observe actual counseling practices and to assess their reported counseling practices respectively. Four different scenarios were developed for the simulated patient visit. A well designed questionnaire and an assessment form were used for the survey and simulated patient visit.Results:In the cross-sectional survey, 84 pharmacists were approached and 78 agreed to participate (92.8 % response rate). Of the respondents, 96.1% agreed/strongly agreed that patient counseling is important and 69.3% strongly agreed that patient counseling should be a professional duty. The most frequent information provided to patients were dosing schedule of drugs, how to take medication, and drug-food interaction. Majority of community pharmacists either strongly agreed (42.1%) or agreed (51.3%) that patients are comfortable towards their counseling practice. A total of 48 simulated visits were conducted and a medicine was dispensed in all visits. In all four scenarios, dosage schedule (100%), how to take medication (97.6%) and drug-food interaction (69.1%) were the most common type of information provided while what to do when dose is missed (100%), contraindication (95.2%) and the importance of compliance or adherence (92.9%) were the most commonly ignored types of information.Conclusions:The present study emphasizes the existing gap in self-reported and actual counseling practices by community pharmacist in Gondar town, Ethiopia. Hence, the ministry of health, local health policy makers and other stakeholders should collaborate to design interventions to improve community pharmacists’ dispensing and counseling practice.

The potassium channel openers flupirtine and retigabine have proven to be valuable analgesics or antiepileptics. Their recent withdrawal due to occasional hepatotoxicity and tissue discoloration, respectively, leaves a therapeutic niche unfilled. Metabolic oxidation of both drugs gives rise to the formation of electrophilic quinones. These elusive, highly reactive metabolites may induce liver injury in the case of flupirtine and blue tissue discoloration after prolonged intake of retigabine. We examined which structural features can be altered to avoid the detrimental oxidation of the aromatic ring and shift oxidation toward the formation of more benign metabolites. Structure–activity relationship studies were performed to evaluate the KV7.2/3 channel opening activity of 45 derivatives. Sulfide analogues were identified that are devoid of the risk of quinone formation, but possess potent KV7.2/3 opening activity. For example, flupirtine analogue 3‐(3,5‐difluorophenyl)‐N‐(6‐(isobutylthio)‐2‐(pyrrolidin‐1‐yl)pyridin‐3‐yl)propanamide (48) has 100‐fold enhanced activity (EC50=1.4 nm), a vastly improved toxicity/activity ratio, and the same efficacy as retigabine in vitro.
