Abstract

Nanosilver is a type of metallic silver nanoparticles and has a particle size of 1-100 nm. The method used in the synthesis of nanosilver is a chemical reduction method with silver metal precursor AgNO3 and a bioreductant of binahong leaf extract containing flavonoid compounds. This study aims to obtain the duration, temperature and optimum point in the synthesis of nanosilver with the bioreductant of binahong leaf extract using the sonication method. This type of research is purely experimental with a 2x2 factorial design. The nanosilver characterization was conducted by determining the optimum wavelength and the transmittance value of the nanosilver formed. The effect of temperature and duration of sonication on the wavelength and % transmittance of the synthesized nanosilver in this study were analyzed by ANOVA statistical test using the Minitab 19 application with a 95% confidence level. In this study, the temperature and duration of sonication as well as their interactions have an effect on the transmittance response. The statistical results of the model have a significant effect on the % transmittance response only with p-value 0.05. The optimum point was found in the synthesis of nanosilver with the bioreductant of binahong leaf extract (Anredera cordifolia (Ten.) Steenis) using a 2x2 factorial design, namely at a sonication temperature of 80°C for 10 minutes, a sonication temperature of 70oC for 15 minutes and a sonication temperature of 80oC for 15 minutes.

Abstract

Tramadol and paracetamol are analgesic drugs that are often combined and made in the form of extemporaneously prepared capsules dosage form to treat moderate to severe pain management. This study aims to determine the quality of prescribed medication of extemporaneously prepared tramadol and paracetamol capsules combination taken from a private hospital in Semarang covering weight uniformity, moisture content, disintegration, and content uniformity. This type of research is a descriptive observational cross-sectional design. Samples were taken using simple random sampling at a pharmaceutical installation in a private hospital in Semarang. The observation result from four types of testing was compared against the standard values of each test’s parameter listed in the Indonesian Pharmacopoeia V. The results are, samples meet the weight uniformity test with an acceptance value of 7.34%; meet the moisture content test with an average moisture content of 2.647% for the first day and 3.04% for the seventh day; meet the disintegration test with a breakdown time of fewer than 15 minutes; and did not meet the uniformity test with acceptance value of 34.06% for paracetamol and 34.30% for tramadol. It can be concluded that the prescribed medication of extemporaneously prepared capsule samples derived from a private hospital in Semarang can fulfill the standard values listed in the Indonesian Pharmacopoeia V except for the content uniformity test.

Abstract

Capsule preparations containing theophylline, salbutamol sulfate, and methylprednisolone were frequently prescribed in a private hospital in Yogyakarta. Theophylline is a narrow therapeutic index drug. Extemporaneous preparation products that contain narrow therapeutic index drugs have to meet the quality requirement. This study aimed to evaluate the quality of the capsule preparations. The sample was taken from a private hospital in Yogyakarta. The samples were assessed for physical characteristics, content uniformity, and chemical stability during storage. The result found that the physical characteristics of the product were good. The coefficients of variance of the content uniformity percentage for theophylline, salbutamol sulfate, and methylprednisolone were 11.96%, 3.33%, and 45.74%, respectively. During 30 days of storage, the content of theophylline, salbutamol sulfate, and methylprednisolone decreased by 1.44%, 7.64%, and 15.7%, respectively. Capsule preparations containing theophylline, salbutamol sulfate, and methylprednisolone did not meet the quality requirement.
