Antibiotics Without Prescription: Factors Affecting Sales and Purchases in the South Banjarbaru District

2026-03-31T06:03:34+00:00

Antibiotics are drugs used to treat bacterial infections and should only be obtained with a doctorâ€™s prescription. However, many people in Indonesia acquire them without one, and regulations are not fully enforced across regions. This study aimed to identify factors influencing the sale and purchase of non-prescription antibiotics. A quantitative approach was used, employing purposive sampling for sales factors and proportional random sampling for purchase factors, with data collected via questionnaires. Data were analyzed using univariate (frequency distribution), bivariate (Kendallâ€™s tau test), and factor analysis methods. Results showed that antibiotic sales without prescriptions were at a moderate level (50%), while purchases were at a low level (65.3%). There was no significant relationship between antibiotic sales and purchases without prescriptions in South Banjarbaru District. The factors that most influence sales are integrity, financial, legal and critical sense, as well as external pressure, while the factors that influence purchasing are integrity, financial,Â ease of access, knowledge, and recommendations/information from others.

2026-03-31T06:03:45+00:00

Captopril, an ACE inhibitor, is commonly prescribed as first-line therapy for hypertension. In practice, patients often combine synthetic drugs with herbal remedies such as bay leaves (Syzygium polyanthum), raising concerns about potential interactions. This study investigated the effect of bay leaf infusion on the pharmacokinetic profile of Captopril in white rats (Rattus norvegicus). Ten rats were divided into two groups: group 1 received 25 mg of Captopril, while group 2 received the same dose in combination with bay leaf infusion. Blood samples were collected via the tail vein at 0; 0.5; 1; 2; 4; 6; 12 and 24 hours, and analyzed using a UV-VIS spectrophotometer (205 nm). Pharmacokinetic parameters assessed included absorption rate constant (ka), elimination rate constant (ke), half-life (tÂ½), peak time (tmax), maximum concentration (Cpmax), and area under the curve (AUC). Results showed that bay leaf infusion increased Cpmax (2.646 â†’ 3.105 Âµg/ml), prolonged tÂ½ (3.347 â†’ 16.116 h), and elevated AUC (23.382 â†’ 56.479 ÂµgÂ·h/ml). These findings indicate that bay leaf infusion significantly alters the pharmacokinetic profile of Captopril.

Integrative Study on the Binding Energy Calculation: Molecular Docking and Molecular Mechanics with Generalized Born Surface Area Targeting Acetylcholinesterase

2026-03-31T06:03:49+00:00

Alzheimer's disease (AD) imposes a significant global financial burden. Previous studies have reported that acetylcholinesterase (AChE) activity is strongly associated with AD, making it a key target in therapeutic research. Molecular docking and computational techniques are increasingly used to study these associations, yet a surge in publications has led to a departure from strictly designed paradigms. This study evaluates the accuracy of the Gibbs free energy of binding (Î”G) from molecular docking scores, Molecular Mechanics/Generalized Born Surface Area (MM/GBSA), and local Vina scores. The Spearman rank test was applied to compare Î”G predictions and the in vitro results from our previous study. The correlation coefficient for molecular docking was -0.491, the MM/GBSA correlation coefficient calculated at the best molecular docking pose was -0.309, the MM/GBSA correlation coefficient calculated at the last 5 nanoseconds (ns) snapshots was 0.164, and the correlation coefficient of the Vina local score calculated at the last 5 ns snapshots was 0.273. Our findings indicate that the Î”G prediction from the Vina local score for the last 5 ns shows the strongest correlation with in vitro results.

Antibiotic Use Patterns in Obstetric and Gynecological Surgery Patients: A Quantitative Descriptive Study Using ATC/DDD and DU90% Methods

2026-03-31T06:03:50+00:00

Surgical site infections (SSIs) are common postoperative complications in obstetric and gynecological surgery, with incidence rates up to 20% in cesarean sections. Antibiotics are the primary strategy for SSI prevention; however, antibiotic utilization patterns in this surgical setting remain poorly characterized locally. This study describes the antibiotic use profile, AWaRe classification, DDD/100 patient-days values, and DU90% segment among obstetric and gynecological surgery patients at Ulin Regional General Hospital, Banjarmasin, in 2024. A retrospective, non-experimental quantitative descriptive design was employed. Of 313 medical records reviewed, 137 met the inclusion criteria. A total of 173 antibiotic prescriptions were identified. Ceftriaxone was the most frequently used antibiotic (61.84%), with cephalosporins predominating (91.91%) and parenteral administration in 75.72% of cases. Based on the WHO AWaRe 2022 classification, 85.55% of antibiotics were in the Watch group and 13.29% in the Access group; no Reserve antibiotics were used. Ceftriaxone had the highest DDD/100 patient-days (33.74). Ceftriaxone and cefixime comprised the DU90% segment. These findings highlight a predominance of Watch-group antibiotics and support the need for targeted stewardship interventions

Molecular Basis for the Enhanced CDK2 Inhibition by Artesunate: Superior Binding Affinity to the ATP-Catalytic Site

2026-04-01T01:02:47+00:00

This study aimed to identify the most potent CDK2 inhibitor among seven artemisinin derivatives and, critically, to elucidate its binding mechanism and compare its affinity with that of the natural ligand, ATP. Molecular docking was performed using AutoDock 4.2.6 toward inactive and active forms of CDK2. Ligands were optimized using the Hartree-Fock method basis set 6-311G. Blind docking on the active form was used to determine the inhibition mechanism, employing the free energy of binding (Î”G) and dissociation constant (K_i) as affinity markers. Artesunate was the most potent derivative, exhibiting the highest affinity towards the active CDK2 form, with a Î”G of -11.7 kcal/mol and a K_i of 2.66 nM. Blind docking confirmed an ATP-competitive inhibition mechanism. Remarkably, Artesunate's K_i was significantly lower than that of ATP (8.73 nM). This enhanced affinity is attributed to specific interactions between the hemisuccinate side chain and the critical amino acid region, from 13-Gly to 16-Gly. Artesunate is suggested as a potent, ATP-competitive CDK2 inhibitor with an affinity exceeding that of ATP. These hypothesis-generating results suggest anticancer potential, yet require validation via MD or assays; limitations like scoring bias and protein flexibility necessitate cautious interpretation regarding the 13-Gly to 16-Gly target.

2026-03-31T06:03:54+00:00

The genus Cyperus is widely recognized as decorative flora. Empirically, Cyperus plants have been utilized to treat wounds, inflammation, and digestive disorders. While the genus is reported to exhibit antioxidant properties, scientific data regarding Cyperus involucratus remains limited. This research aimed to identify antioxidant compounds in C. involucratus using Ultra-High-Performance Liquid Chromatography-High Resolution Mass Spectrometry (UHPLC-HRMS). The C. involucratus methanolic extract was obtained through maceration using a 70% methanol solvent. Separation was performed using a UHPLC gradient system with a flow rate of 0.3 mL/min , while compound identification was conducted using a Quadrupole-Orbitrap MS detector in positive mode. The radical scavenging activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The analysis identified 175 metabolites within the methanolic extract. Based on mzCloud library matching with confidence scores of 97.4â€“100%, 12 primary bioactive compounds were identified: oleamide, Î± -linolenic acid, kaempferol, scutellarin, hexadecanamide, 1-linoleoyl glycerol, 1-stearoy-rac-lglycerol, adenine, adenosine, L-tyrosine, stearamide and nootkatone. The extract possessed a moderate radical scavenger with an IC₅₀ value of 57.94 Î¼g/mL. These findings provide a scientific foundation for further investigation of C. involucratus as a potential natural antioxidant, although further in vivo studies are required to validate its broader pharmacological outcomes.

Evaluation of the Rationality of the Use of Antibiotics in Paediatric Diarrheal Patients in Hospital Inpatient Facilities in the City of Bandung

2026-03-31T06:03:55+00:00

Diarrhoea in children is often associated with irrational antibiotic use, even though the cause is not bacterial infection. Excessive antibiotic use can increase antibiotic resistance, a significant problem in healthcare. This study aimed to evaluate the rationality of antibiotic use in paediatric inpatients with diarrhoea at a single hospital in Bandung, including demographic characteristics, types of antibiotics used, and appropriate indication, drug selection, dosage, and administration intervals. This study was observational, using a non-experimental descriptive analysis design. Data collection was conducted retrospectively from January to December 2024. Out of a total population of 229 patient medical records, 54 patient medical records met the inclusion criteria and were used as the study sample. The rationality of drug use refers to the Indonesian Ministry of Healthâ€™s guideline. The results showed that 55.6% of patients were male, with toddlers (46.2%) being the largest age group. Ceftriaxone was the most commonly prescribed antibiotic (24%). The rationality of antibiotic use was 100% for indications and drug selection, 94.4% for dosage, and 90.7% for the interval between doses. However, the identified discrepancies in dosage (5.6%) and administration intervals (9.3%) require immediate attention to minimize the risk of therapeutic failure and antibiotic resistance.Â

Evaluation of Extraction Methods on the Antioxidant Potential of Balik Angin Leaves Ethanol Extract (Alphitonia incana (Roxb.) Teijsm. & Binn. ex Kurz)

2026-03-31T06:03:56+00:00

Alphitonia incana, also known locally as balik angin, is an endemic natural antioxidant plant of Borneo. The objective of the present work was to compare the effectiveness of maceration and Soxhlet extraction of balik angin leaves with respect to antioxidant activity and phenolicâ€“flavonoid content. Ethanolic extracts were prepared using both extraction methods, and the phenolic-flavonoid content was quantified spectrophotometrically. Antioxidant performance was assessed through DPPH, CUPRAC, and FRAP assays. The findings revealed that the Soxhlet-derived extract contained higher concentrations of phenolic-flavonoid compounds than those produced by maceration. In addition, the Soxhlet-derived extract demonstrated stronger antioxidant activity, as evidenced by lower ICâ‚…â‚€ and ECâ‚…â‚€ values in the DPPH (10.872 ppm) and CUPRAC (6.578 ppm) assays compared with the macerated extract (ICâ‚…â‚€ 13.127 ppm; ECâ‚…â‚€ 14.034 ppm) and was classified as a very strong antioxidant. The FRAP assay further supported these results, with ferric reducing power values of 1,484.1 mg AAE/g extract for the Soxhlet-derived extract and 1,295.8 mg AAE/g extract for the macerated sample. Overall, the study concludes that Soxhlet extraction is more effective than maceration in enhancing the antioxidant potential of balik angin leaf, a result that is closely associated with their elevated phenolic and flavonoid content.

Acute Oral Toxicity of Methanolic Extracts from the Fruit and Leaf of Parijoto (Medinilla speciosa Blume) in Mice

2026-03-31T06:03:57+00:00

Medinilla speciosa Blume, or parijoto, contains flavonoids, saponins, alkaloids, and tannins with pharmacological potential. However, information regarding its safety profile, particularly acute toxicity data, is still very limited, so research is needed to evaluate its safety level. This study aims to evaluate the acute oral toxicity of M. speciosa leaf and fruit extracts in ddY mice. This study used a true experimental design. M. speciosa leaf and fruit extracts were obtained by ultrasonic-assisted extraction with methanol as a solvent. The acute oral toxicity test was conducted with a fixed-dose method at a single dose of 2000 mg/kgBW. Parameters observed for 14 days included mortality, clinical symptoms of toxicity, body weight changes, relative organ weights, and histopathological analysis of the liver and kidneys. The findings indicated an absence of fatalities across all treatment groups. The LD₅₀ values for both extracts were determined to exceed 2000 mg/kgBW, categorising the fruit and leaf extracts as mildly toxic (category 5). Mild toxic symptoms were only observed in the treatment group receiving the fruit extract. Histopathological analysis of the liver and kidneys revealed mild cellular changes that were not statistically significant. Therefore, a single oral administration of M. speciosa fruit and leaf extracts at doses up to 2000 mg/kgBW is relatively safe.

In silico Evaluation of Quercetin and Apigenin from Litsea angulata as Potential Dual Binders of DPP-4 and SUR1

2026-03-31T06:03:58+00:00

Litsea angulata leaves have traditionally been used for diabetes management; however, the molecular mechanisms underlying their antidiabetic activity remain poorly understood. This study aimed to evaluate the interaction potential of two major flavonoids from L. angulata, quercetin and apigenin, against two protein targets associated with type 2 diabetes mellitus: dipeptidyl peptidase-4 (DPP-4, PDB ID: 1X70) and sulfonylurea receptor 1 (SUR1, PDB ID: 5YKG). Ligand structures were optimized using density functional theory at the B3LYP/6-31G level, followed by molecular docking simulations using AutoDock Vina. Sitagliptin and glibenclamide were used as reference ligands for DPP-4 and SUR1, respectively. The docking results showed that quercetin and apigenin exhibited moderate binding affinities toward DPP-4 (â€“8.0 and â€“7.5 kcal/mol), interacting with key residues including Arg125 and Tyr547. In contrast, both flavonoids demonstrated stronger predicted binding energies toward SUR1 (â€“9.1 and â€“9.0 kcal/mol) compared with glibenclamide (â€“8.8 kcal/mol), although the interactions occurred at residues different from the primary functional binding site. The proteinâ€“ligand interactions were mainly stabilized by Ï€â€“Ï€ stacking and van der Waals interactions rather than strong hydrogen bonds. Additional in silico analysis indicated that both compounds possess favorable physicochemical and pharmacokinetic properties based on ADME prediction, while toxicity assessment suggested relatively acceptable safety profiles. These findings indicate that quercetin and apigenin may serve as promising flavonoid scaffolds for the development of antidiabetic agents targeting multiple proteins involved in glucose regulation. Further experimental studies are required to validate their pharmacological activity and clarify their mechanisms of action.

Molecular Docking Studies and ADME-Tox Prediction of Phytocompounds from Lycopersicon esculentum mill. as a Drug Candidate for Alopecia Treatment

2026-03-31T06:03:59+00:00

Alopecia is a disorder of the hair follicles that causes hair loss, either in limited areas or throughout the entire body. This study aims to evaluate the potential and molecular interactions of compounds found in the Rampai plant (Lycopersicon esculentum Mill.). The Rampai plant is known to contain various secondary metabolites such as alkaloids, flavonoids, arbutin, amygdalin, and pectin, which have the potential to be developed as antialopecia drug candidates through an in-silico approach to androgen receptors (PDB ID: 4K7A) and ADME-Tox profile predictions. The in-silico approach was conducted using the molecular docking method to predict the interaction between the active compounds from the Rampai plant and the androgen receptor using Autodock Tools 1.5.7 and Vina software, while the ADME-Tox analysis was conducted through the pkCSM platform. The molecular docking results showed that the reference ligand (Minoxidil) had an affinity energy of âˆ’7.353 kcal/mol, while the test compound with the best affinity was isorhamnetin with a value of âˆ’8.398 kcal/mol, which was lower (more stable) than Minoxidil. In addition, the ADME-Tox prediction results for isorhamnetin show favorable pharmacokinetic characteristics, especially in terms of skin permeability, absorption and distribution. Thus, isorhamnetin has the potential as an androgen receptor antagonist and a role in the development of therapies for alopecia.

2026-03-31T06:04:01+00:00

Acne vulgaris is a cutaneous disorder associated with Propionibacterium acnes and Staphylococcus aureus. This study investigated the antibacterial activity of patindis leaf extract (Urophyllum arboreum) and its microneedle acne patch against both bacteria. The extract was prepared from dried simplicia by maceration using 96% ethanol. Phytochemical screening was conducted using test-tube methods. Antibacterial testing included determination of inhibition zone diameter using the well-diffusion method, as well as the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Clindamycin 1% was used as a positive control, while 20% DMSO and microneedle patches without extract served as negative controls. The U. arboreum leaf extract contained flavonoids, alkaloids, saponins, condensed tannins and terpenoids. At concentrations of 1.25%, 2.5%, and 5%, the extract produced inhibition zones of 12.368, 14.693, 18.403 mm against P. acnes and 14.523, 17.408, 18.840 mm against S. aureus, respectively. The MIC and MBC values against both bacteria were 0.625%. The microneedle acne patch formulations produced inhibition zones of 9.196 mm (F1), 10.140 mm (F2), and 10.713 mm (F3) against P. acnes, but showed no activity against S. aureus. These results indicate that the microneedle acne patch containing U. arboreum leaf extract has potential as an alternative topical antibacterial agent.
