  • Objectives : The purpose of this study is to investigate the etahnol extract of Saururus Herba and their dermal boiactivity properties related to cosmeceuticals such as depigmentation and radical scavenging effect. Methods : Using B16/F10 Melanin cells, we measured depigmentation effect of the etahnol extract of Saururus Herba. Antioxidant activities of the etahnol extract of Saururus Herba were determined by DPPH radical scavenging activity. Results : The etahnol extract of Saururus Herba showed considerable radical scavenging activity($SC_{50}$ : 25 ${\mu}g$/ml). Antioxidant activity is in a dose dependant manner. The etahnol extract of Saururus Herba down-regulated melanin synthesis effectively. B16 cells incubated with the etahnol extract of Saururus Herba showed reduces melanin formation and tyrosinase activity. The etahnol extract of Saururus Herba alone markedly suppressed melanin content and tyrosinase activity. Conclusions : These results suggest that the ethanol extract of Saururus Herba is a potent depigmentaion agent and it may be a candidate for antioxidant agent.

  • Background: Drug-related problems have the potential to threaten patient health, and pharmacists are in a position to prevent such problems through prescription reviews and patient counseling, actively engaging in pharmaceutical care activities. This study aims to categorize and analyze the intervention activities of pharmacists in community pharmacies concerning drug-related problems, following international criteria. Methods: Over a six-month period, prescription interventions completed in a community pharmacy in Seoul were selected as the research subjects. The causes of interventions were classified according to the Pharmaceutical Care Network Europe (PCNE) drug-related problems (DRPs) classification system and the types and frequencies of DRPs were identified. Results: Among a total of 49,334 prescriptions, 527 interventions were completed, constituting approximately 1.07% of the daily average filled prescriptions. Individuals over 60 years of age represented more than 50%. The primary cause of DRPs was prescribing and drug selection issues, comprising 256 cases (48.58%), with specific subcategories including 109 cases of drug selection, 79 cases of treatment duration errors, 47 cases of dose selection, and 21 cases of inappropriate dosage form selection. Patient-related issues accounted for 204 cases (38.71%). Conclusion: The study demonstrated that the pharmacists' intervention in community pharmacies contributes to the safe use of medication by patients.

  • Sihosamultang(SST) has been used for the treatment of puerperal fever, liver disease in traditional medicine. The present study was carried out to evaluate the antioxidant effects of SST extract in vitro. The inhibitory effect of SST extract on lipid peroxidant was examined in the linoleic acid autoxidation system. In this test, SST extract significantly inhibited the time course of the lipid peroxidation. And SST extract showed about 73% scavenging effect on DPPH radical. And this extract inhibited not only the lipid peroxide formation induced by hydroxyl radical derived from $ H_{2}O_{2}-Fe^{2+}$ in the rat liver homogenate, but also the superoxide generation from xanthine-xanthine oxidase system in a dose-dependent manner. In addition, SST extract protected the hepatic cell death induced by tert-butyl hydroperoxide. These data indicated that SST might play a protective role against oxidative injury by free radicals.

  • This study was performed to evaluate the acute oral toxicity of an oriental medical prescription for obesity treatment, SH21-B, in Sprague-Dawley rats and Beagle dogs. SH21-B was administered in rats at does of 0mg/kg, 2,000mg/kg, and 5,000mg/kg. And also SH21-B was administered in Beagle dogs at does of 150mg/kg, 300mg/kg, and 600mg/kg. The rats and dogs of both sexes were observed daily for 14 days after single oral administration. Two female rats, one administered at 2,000mg/kg and the other administered at 5,000mg/kg, died, but no dead animal was observed among male rats. Therefore LD50 in the female rat is observed to be 8,710mg/kg, and MLD(Minimum Lethal Dose) of the male rat is observed to be more than 5,000mg/kg. Among dogs, no dead animal was observed up to 600mg/kg and MLD is observed to be more than 600mg/kg.

  • Background/Aims: Despite short-acting β2-agonist (SABA) overuse being associated with poor asthma outcomes, data on SABA use in South Korea is scarce. Herein, we describe prescription patterns of SABA and other asthma medications in patients from the South Korean cohort of the SABA use IN Asthma (SABINA) III study. Methods: This study included patients with asthma aged ≥ 12 years, who had ≥ 3 consultations with the same healthcare provider, and medical records containing data for ≥ 12 months prior to the study visit. Patients were classified by investigator-defined asthma severity (per 2017 Global Initiative for Asthma recommendations) and practice type (primary or specialist care). Data on disease characteristics, asthma treatments, and clinical outcomes in the 12 months before the study visit were collected using electronic case report forms. Results: Data from 476 patients (mean age, 55.4 years; female, 63.0%) were analyzed. Most patients were treated by specialists (83.7%) and had moderate-to-severe asthma (91.0%). Overall, 7.6% of patients were prescribed ≥ 3 SABA canisters (defined as over-prescription). In patients prescribed SABA in addition to maintenance therapy, 47.4% were over-prescribed SABA. Most patients (95.4%) were prescribed a fixed-dose combination of an inhaled corticosteroid and a long-acting β2-agonist as maintenance therapy. Although asthma was well-controlled/partly-controlled in 91.6% of patients, 29.6% experienced ≥ 1 severe asthma exacerbation. Conclusions: SABA over-prescription was reported in nearly 50% of patients prescribed SABA in addition to maintenance therapy, underscoring the need to align clinical practices with the latest evidence-based recommendations and educate physicians and patients on appropriate SABA use.

  • Background Clinical practice guidelines (CPG) are systematically developed statements to assist practitioners and patients on healthcare decisions. They provide recommendations for the average patient, which should take into account individual clinical judgment and the patient's values and expectations. Ephedra has sympathomimetic effect and has been used for weight loss worldwide. However, its safety is controversial especially in autonomic and cardiovascular systems. Therefore, the need of appropriate CPG for ephedra prescription in obesity was advocated in Korean Traditional Medicine. Methods The committee comprised of specialists of obesity, oriental herbology, oriental cardiology, constitutional medicine. The committee collected all relevant references about adverse effect and safety of ephedra in the forms of meta-analysis, systematic review, randomized controlled trial, case-control study and observational study from international and domestic databases and paper journals. 11 English- and 5 Korean-language references were gathered and categorized by PICO (Patient, Intervention, Comparison, Outcome) method. We could not complete strength of recommendation which should be clarified according to the evidence grade estimation. Result The first version of CPG for ephedra prescription in obesity was issued by Korean Oriental Association for Study of Obesity. It includes topics of introduction, pharmacokinetics, side effects and adverse events, constitutional aspect and recommendations for dose, indication and contraindication. Conclusion There should be periodic upgrade of this CPG from now on. Although there are some drawbacks in this version of CPG, it has significance as the first CPG in Korean Traditional Medicine.

  • Background: The number of patients with dementia continues to increase as the age of aging continues to grow. Psychiatric symptoms caused by senile dementia are controlled using antipsychotics. However, these antipsychotics can lead to Parkinson's disease, and abuse of dopamine derivatives such as levodopa among Parkinsonian drugs can lead to psychosis. Therefore, we evaluated the patterns of prescribed antipsychotics and antiparkinsonian drugs in patients with senile dementia. Methods: We used data from the sample of elderly patients from the Health Insurance Review and Assessment Service (HIRA-APS-2016). We analyzed the patterns of prescribing antipsychotics and antiparkinsonian drugs including prescribed daily dosage, period of prescription, and number of patients with both antipsychotics and antiparkinsonian drugs for senile dementia. Results: Among the 159,391 patients with dementia included in this analysis, 4,963 patients (3.1%) and 16,499 patients (10.4%) were prescribed typical and atypical antipsychotic drugs, respectively. The most frequently prescribed typical antipsychotic was haloperidol (4,351 patients with dementia), whereas the atypical agent was quetiapine (12,719 patients). The most frequently prescribed antiparkinsonian drugs were in the order of levodopa/carbidopa, benztropine, and ropinirole. In addition, 1,103 and 3,508 patients prescribed typical and atypical antipsychotics, respectively, were co-prescribed antiparkinsonian drugs. Conclusions: Atypical antipsychotics were the preferred prescription in patients with senile dementia. The prescription dose was relatively low; however, the average treatment duration was mostly long-term. Selection of antipsychotics and/or antiparkinsonian drugs should be made carefully in senile dementia and the causal relationship of adverse drug reactions needs further study.
