Korean Journal of Clinical Pharmacy 2025;35(3):177-186
Background:
This study aims to analyze the experiences of self-medication for minor symptoms, examine over-the-counter (OTC) drug usage patterns, and evaluate consumer satisfaction with pharmacy services to explore future improvements in self-medication practices.
Methods:
A 27-item questionnaire was used in this cross-sectional survey to examine self-medication experiences for minor ailments among adults living in Korea during March to April 2019 through an online channel.
Results:
Of the 354 respondents, 98.9% experienced minor symptoms such as cough, cold, headache, muscle pain, indigestion, lower back pain, sore throat, diarrhea, body aches, heartburn, constipation, and fever for the past year. 31.9% purchased OTC medication from pharmacies, 37.6% visited healthcare providers such as clinics, and 30.5% rested at home, to cope with them. The main advantage of self-medication wasidentified as being easier and more convenient than physician visits, while the primary concern was uncertainty about the accuracyof self-diagnosis. 91.8% purchased OTC drugs from a pharmacy in the past year, 53.8% trusted pharmacists’ product choices, and72.6% were satisfied with pharmacists’ medication guidance. In cases of chronic illness, the rate of visits to hospitals, clinics, orpharmacies was higher, while the proportion of those who “endure and bear with it” was lower (p = 0.012).
Conclusion
This study highlights the crucial role of pharmacists in improving the quality of self-medication and provides foundational data for enhancing pharmacy services.

Journal of the Korean Ophthalmological Society 2024;65(3):218-225
Purpose:
To document the distribution and clinical features of iridocorneal endothelial (ICE) syndrome in its various subtypes observed in patients who visited a single institution in Korea.
Methods:
A retrospective analysis was conducted on the medical records of patients diagnosed with ICE syndrome at the Department of Ophthalmology, Yeungnam University Hospital, from 1993 to 2023. The cases were classified into Chandler syndrome, progressive iris atrophy, and iris nevus syndrome based on the severity of corneal and iris abnormalities. We also examined the presence of glaucoma, corneal edema, and iris abnormalities at diagnosis.
Results:
In all, 22 eyes from 21 patients with ICE syndrome were included. The mean age at diagnosis was 56.6 ± 16.1 years with a female predominance (20 patients, 95.5%). The syndrome was primarily unilateral (20 patients, 95.5%). Subtypes included 9 eyes with Chandler syndrome (40.9%), 7 eyes with progressive iris atrophy (31.8%), and 6 eyes with iris nevus syndrome (27.3%). Glaucoma was present in 15 eyes (68.2%), with 8 eyes (36.4%) undergoing glaucoma surgery. Of the 7 eyes that had trabeculectomy as initial glaucoma surgery, six experienced poor intraocular pressure control leading to Ahmed valve implantation in 4 cases. Corneal edema was noted in 10 eyes (45.5%) at diagnosis progressing to corneal decompensation in 6 eyes (27.3%).
Conclusions
ICE syndrome in Korea predominantly affects middle-aged women and occurs unilaterally with Chandler syndrome being the most common subtype. Given the high risk for glaucoma development, suboptimal outcomes of trabeculectomy, and significant risk for corneal decompensation, ongoing management efforts are essential for glaucoma and corneal function preservation.

Korean Circulation Journal 2024;54(9):534-544
Background and Objectives:
Lipid lowering therapy is essential to reduce the risk of major cardiovascular events; however, limited evidence exists regarding the use of statin with ezetimibe as primary prevention strategy for middle-aged adults. We aimed to investigate the impact of single pill combination therapy on clinical outcomes in relatively healthy middleaged patients when compared with statin monotherapy.
Methods:
Using the Korean National Health Insurance Service database, a propensity score match analysis was performed for baseline characteristics of 92,156 patients categorized into combination therapy (n=46,078) and statin monotherapy (n=46,078) groups. Primary outcome was composite outcomes, including death, coronary artery disease, and ischemic stroke. And secondary outcome was all-cause death. The mean follow-up duration was 2.9±0.3 years.
Results:
The 3-year composite outcomes of all-cause death, coronary artery disease, and ischemic stroke demonstrated no significant difference between the 2 groups (10.3% vs.10.1%; hazard ratio [HR], 1.022; 95% confidence interval [CI], 0.980–1.064; p=0.309).Meanwhile, the 3-year all-cause death rate was lower in the combination therapy group than in the statin monotherapy group (0.2% vs. 0.4%; p<0.001), with a significant HR of 0.595 (95% CI, 0.460–0.769; p<0.001). Single pill combination therapy exhibited consistently lower mortality rates across various subgroups.
Conclusions
Compared to the statin monotherapy, the combination therapy for primary prevention showed no difference in composite outcomes but may reduce mortality risk in relatively healthy middle-aged patients. However, since the study was observational, further randomized clinical trials are needed to confirm these findings.

Korean Journal of Clinical Pharmacy 2024;34(2):126-133
Background:
Medication’s benefits and harms require careful management. Laws mandate pharmacists to provide essential med-ication details since inadequate counseling may pose risks. This study explores public expectations for pharmacist-provided side effect information to enhance safety.
Methods:
A self-developed questionnaire was created for participant to self-report, refined through pilot surveys with experts and laypersons. Nineteen items were categorized into four sections, using closed-ended ques-tions. Adults over 20, having obtained prescription medications within the past year, were surveyed via convenience sampling.Data analysis employed descriptive statistics and T-tests using IBM SPSS Statistics 21 and Microsoft Excel.
Results:
The study involved 189 participants, with a slightly higher proportion of females (59.3%) than males (40.7%), predominantly in their 20s (45.0%) and college graduates (57.1%). Health professionals represented 76.2% of respondents. Over half visited pharmacies at least 5 times yearly for prescriptions. Indirect experience with side effects was more common (30.2%) than direct experience (17.5%). Most (82.0%) showed interest in media-reported side effect events. Satisfaction with pharmacist-provided side effect explanations was low (59.7%), but importance was high (98.9%). Preferences favored combined verbal and written explanations (65.1%), with a majority desiring explanations for common but less serious side effects (82.5%). Healthcare professionals found explanations significantly more sufficient than non-professionals did. Older individuals, those living with elderly, and frequent pharmacy visitors attributed greater importance to pharmacist-provided explanations.
Conclusion
Koreans view pharmacist-pro-vided medication side effect explanations as vital but find current services lacking. Enhancements in content and delivery meth-ods are needed in pharmacy counseling to meet public expectations.

Korean Journal of Clinical Pharmacy 2024;34(1):30-38
Background:
This study examined the public’s perceptions of repeat dispensing as one of the measures to reduce the harmful effects of long-term prescriptions in Korea.
Methods:
From January 11 to 25, 2021, an online survey was conducted for adults using convenience sampling. A self-developed questionnaire was used.
Results:
There were 310 respondents, of which 228(73.5%) preferred repeat dispensing. When considering the additional fee payment, 188 (60.6%) preferred repeat dispensing, and54 (67.5%) out of a total of 80 chronic disease patients preferred it. It was confirmed that there was a difference in the willingnessto repeat dispensing considering the additional cost depending on whether the patient had a chronic disease and the distance from home to the nearest pharmacy. As a result of subgroup analysis for patients with chronic diseases, frequency of outpatient visit, number of prescription days, method of packaging pharmaceuticals, and distance from home to the nearest pharmacy were iden-tified as variables that could well predict the willingness to repeat dispensing considering paying additional fees. The preferencefor repeat dispensing may vary depending on conditions such as additional cost range, frequency and period of prescription use, disease and patient characteristics, so a careful approach is necessary.
Conclusion
It is necessary for the government to consider the introduction of repeat dispensing with interest in the public demand.

This report presents the latest statistics on the stroke population in South Korea, sourced from the Clinical Research Collaborations for Stroke in Korea-National Institute for Health (CRCS-K-NIH), a comprehensive, nationwide, multicenter stroke registry. The Korean cohort, unlike western populations, shows a male-to-female ratio of 1.5, attributed to lower risk factors in Korean women. The average ages for men and women are 67 and 73 years, respectively.Hypertension is the most common risk factor (67%), consistent with global trends, but there is a higher prevalence of diabetes (35%) and smoking (21%). The prevalence of atrial fibrillation (19%) is lower than in western populations, suggesting effective prevention strategies in the general population. A high incidence of large artery atherosclerosis (38%) is observed, likely due to prevalent intracranial arterial disease in East Asians and advanced imaging techniques.There has been a decrease in intravenous thrombolysis rates, from 12% in 2017–2019 to 10% in 2021, with no improvements in door-to-needle and door-to-puncture times, worsened by the coronavirus disease 2019 pandemic. While the use of aspirin plus clopidogrel for noncardioembolic stroke and direct oral anticoagulants for atrial fibrillation is well-established, the application of direct oral anticoagulants for non-atrial fibrillation cardioembolic strokes in the acute phase requires further research. The incidence of early neurological deterioration (13%) and the cumulative incidence of recurrent stroke at 3 months (3%) align with global figures. Favorable outcomes at 3 months (63%) are comparable internationally, yet the lack of improvement in dependency at 3 months highlights the need for advancements in acute stroke care.
