Abstract

Background: Low solubility in water is a major obstacle for Meloxicam (MLX) and has implications for its limited bioavailability. Nanocrystallization techniques show potential for improving drug solubility, but nanoparticles tend to aggregate, suggesting the use of a combination of Hydroxypropyl Methylcellulose (HPMC) and Decyl Glucoside (DG) as stabilizers to overcome this problem.Objective: This study aims to develop and characterize meloxicam nanocrystals (MLX-NC) with a combination of HPMC and DG in an effort to improve solubility. MLX-NC was synthesized using ultrasonication and dried by lyophilization.Methods: The resulting formulation exhibited excellent physical stability over 28 days, as evidenced by consistent particle size (~11 nm) and polydispersity index (<0.3). Physical evaluation and characterization were performed, including particle size analysis (DLS), zeta potential, particle morphology (SEM), thermal analysis (DSC), X-ray diffraction (XRD), and saturated solubility testing.Results: The MLX-NC formulation showed a more than 200-fold increase in solubility compared to pure MLX, from 0.005 mg/mL to 1.064 mg/mL. XRD and DSC analyses confirmed that the nanocrystallization process converted the crystalline phase of MLX into an amorphous phase. These results indicate that induced amorphization can significantly improve solubility.Conclusion: The solubility of MLX can be significantly improved using ultrasonication combined with HPMC and DG. This approach has the potential to overcome the solubility limitations of BCS Class II drugs.

Abstract

The sticking phenomenon is a critical issue in the production of calcium carbonate–cholecalciferol (vitamin D3) chewable tablets, primarily driven by the hygroscopicity and reactivity of citric acid, which is used as a flavor-masking agent. This study aims to evaluate and determine the optimal method for mitigating sticking by modifying citric acid excipients using two approaches: granulation with mannitol (F1: 0.5%, F2: 1%) and coating with HPMC (F3: 0.5%, F4: 1%). The evaluation was conducted on the properties of the granule mass and quantitatively measured the percentage of sticking in industrial-scale modifications for 24 hours. The results showed that the control formula (F0), without modification, had the lowest sticking percentage (10.88%) and the highest moisture content (3.36%), as indicated by a "passable" flow property with a compressibility index of 21.47%. The 1% HPMC coating modification method (F4) was successful in eliminating stickiness to 0%, supported by moisture-control data (2.25%) and a significant improvement in powder-flow properties to “fair,” with a compressibility index of 17.06%. Although the 1% mannitol granulation method (F2) is relatively effective in reducing stickiness (0.85%), the 1% HPMC coating (F4) is more effective at physically isolating citric acid. This study concludes that the HPMC coating method is superior to the granulation method for physically isolating citric acid, yielding stable, non-sticking calcium carbonate–cholecalciferol chewable tablets.

Abstract

A persistent and abnormal increase in blood pressure in the arteries is known as hypertension (HT. This research aims to assess the consumption of antihypertension at the Puskesmas Central Cimahi. Non-analytical descriptive methods were used in this investigation. Retrospective data was collected by accessing patient prescriptions and medical record data. Fifty-six patient samples in this study met the inclusion requirements. Quantitative and qualitative methods are used to evaluate rationality. Quantitative data analysis is processed to determine the number of patients, gender, age, and type of drug classification. Qualitative data analysis is processed to evaluate the appropiate of the indication, drug, patient and dose. Based on the research results, 52 people suffered from stage 1 hypertension, and four patients suffered from stage 2 hypertension. Amlodipine monotherapy was the most frequently prescribed drug, namely 92%. While the combination of amlodipine, captropil, amlodipine, and hydrochlorothiazide amounted to 4%. The rationality of treating hypertensive patients who meet the right indications, the right drug, the right patient and the right dose is 100%. It can be concluded that the evaluation and use of hypertension medication at the Puskesmas Central Cimahi as a whole meets the criteria for rational treatment.
