In-vitro diffusion study of ibuprofen-ï¢-cyclodextrin inclusion complex nanogel
Get PDFThe inclusion complex is one way to enhance active substance solubility, affecting medicine dissolution and penetration. The inclusion complex is formed by utilizing b-cyclodextrin as the host of the active compounds. The Ibuprofen (2-(4-isobutyl-phenyl)propionate) is a propionate acid derivative and classified in class II of the Biopharmaceutic Classification System, which has low dissolutions and high permeability. This study aims to develop a nanogel containing ibuprofen-β-cyclodextrin inclusion complex with the ratio of 1:1, 1:2 and 2:1; and to compare the in-vitro diffusion profile with pure ibuprofen gel. The inclusion complex of ibuprofen-β-cyclodextrin was prepared using the coprecipitation method with the three molar comparison ratio of 1:1, 1:2, and 2:1. The in-vitro study was performed using the gel-based viscolam, comparing the three formulas of ibuprofen-β-cyclodextrin with pure ibuprofen gel. The ibuprofen concentration of each gel tested in the experiment was 1%. The particle size characterization of ibuprofen-β-cyclodextrin inclusion complex gel resulted in having nanoparticle size (510 nm). This characteristic indicates that the inclusion complex gel could enhance the cumulative release amount of ibuprofen compared with pure ibuprofen gel with a relatively smaller particle size (156 nm). Pure ibuprofen and inclusion complex powder size measured to be 763 nm and 957 nm, respectively. The ibuprofen-b-cyclodextrin inclusion complex gel with a molar ratio of 2:1 demonstrated an increase in in-vitro diffusion profile of ibuprofen with a cumulative release amount of 740.3 µg.cm-2. Meanwhile, pure ibuprofen gel had the cumulative release amount of 294.74 µg.cm-2. The gel containing ibuprofen-β-cyclodextrin inclusion complex could enhance the cumulative release amount of ibuprofen compared to pure ibuprofen gel. The ibuprofen-β-cyclodextrin inclusion complex gel at a ratio of 2:1 exhibited an increase in the diffusion of ibuprofen in-vitro
The effect of physician prescribing patterns based on ESC guidelines on morbidity improvement among heart failure patients
Get PDFData from Basic Health Research shows the prevalence of heart failure in Indonesia is between 0.1% to 0.3% of the entire Indonesian population. This number is predicted to increase from year to year. Heart failure is a complex syndrome that can cause abnormalities in the structure and function of the heart. Based on the ejection fraction values, there are three types of heart failure, namely HFrEF (EF: < 40%), HFmrEF (EF: 40-49%), and HFpEF (EF: ≥ 50%). Considering that the type of heart failure requiring treatment according to ESC guidelines is only HFrEF, however, this study would also evaluate the effect of physician prescribing patterns on the morbidity of HFmrEF. The recommendations from ESC guidelines to the treatment of HFrEF that can reduce morbidity and mortality are three medication combinations, namely ACE inhibitors/angiotensin receptor blockers, beta-blockers, and aldosterone antagonists. Therefore, this study aims to determine the effect of the suitability of physician prescribing patterns according to ESC guidelines on improving the morbidity of heart failure patients in HFrEF and HFmrEF type. Improvements in morbidity can be seen from the quality of life score and frequency of hospitalization by using questionnaires. The study was conducted in the cardiology outpatient clinic of Dr. Saiful Anwar General Hospital and Islamic Hospital of Aisyiyah in April-May 2019. Subjects who participated in the study were 57 patients. The One-way ANOVA test results showed no significant difference between physician prescribing patterns of quality of life scores on HFrEF (p = 0.944) while the Kruskal Wallis test for the same parameters on HFmrEF also showed insignificant results (p = 0.210). The Kruskal Wallis test results showed no significant difference between the patterns of physician prescribing to the frequency of hospitalization in both HFrEF and HFmrEF (p = 0.260; p = 0.428). The results showed that physician prescribing patterns in accordance with ESC guidelines resulted in the best quality of life scores on HFrEF. The lowest frequency of hospitalization was also shown in HFrEF patients who received treatment according to ESC guidelines
Formulation optimization and antioxidant test for Self-nano emulsifying drug delivery system of soursop leaves (Annona muricata L.) chloroform extract using candlenut oil as oil phase
Get PDFSoursop leaves (Annona muricata L.) chloroform extract has an anticancer agent that can be developed for traditional medicine preparation, even though the extract's solubility is low in the water. This study aims to generate new soursop leaves chloroform extract in the Self-Nano Emulsifying Drug Delivery System (SNEDDS). The expected result is that the solubility increases so that the drug delivery system is more effective. The extraction process of soursop leaves uses the percolation method with chloroform as a solvent. It used tween 80 and cremophore E.L. as surfactant, propylene glycol as a cosurfactant, and candlenut oil as a carrier, to make the SNEDDS formulation. Then performed a comparison between the optimal parameters for the physical properties of the SNEDDS formulation with the predictive Simplex Lattice Design (SLD) formulation with the students' t-test statistical analysis [p> 0.05]. Then carried out several tests such as loading dosage extractability, accelerated stability test, particle size, and zeta potential. Furthermore, the antioxidant test was carried out using the DPPH reagent. The optimum composition of candlenut oil, propylene glycol, a mixture of tween 80, and cremophor E.L. based on SLD is 12%: 22%: 66%, respectively. The SNEDDS optimum formulation for chloroform extract of soursop leaves produces a stable nanoemulsion, homogenous. It has a transmittance value of 90.58% ± 0.151, emulsification time of 59.44 ± 1.763 seconds, and a value of separation phase 1. The physical formulation test results showed no significant difference between observations with predictive design expert software. SNEDDS can produce 25.0 mg of soursop chloroform extract with particle size 411.4 nm, polydispersion index 0.482, and zeta potential 34.2 mV. IC50 value in 36.28 ppm indicated the antioxidant potential of the SNEDDS formulation for chloroform extract of soursop leaves is high
Ointment formulation of snakehead fish (Channa striata) Extract with variations of CMC-Na and carbopol
Get PDFÂ Snakehead fish (Channa striata) and kelulut honey (Trigona sp.) have the potential to accelerate the wound-healing process. These natural ingredients are formulated in the form of ointment because ointment is an external medicine that is easy to apply and has long contact with the skin. Previous research has shown that the snakehead fish extract ointment undergoes phase separation, so it needs a material that can bind the snakehead fish extract and kelulut honey as the active substances in the preparation. This study aimed to determine the effect of variations in the concentration of CMC-Na (3%, 4.5%, 6%) and Carbopol (0.5%, 1%, 2%) as a binder on the ointment physical properties and to determine the best snakehead fish (Channa striata) extract ointment formulation. The ointment of snakehead fish extract was tested for organoleptic, homogeneity, spreadability, and adhesion. The test results were analyzed by One Way ANOVA with a confidence level of 95%. The results showed that the higher the concentrations of CMC-Na and Carbopol used, the greater the adhesive power and the lower the spreadability. Ointment with Carbopol has a wider spreadability and a softer consistency than ointment with CMC-Na. The best formulation is shown by the Carbopol 0.5% (F4) formula, where the average spreadability with a load of 150 g is 5.09 cm and the average adhesion is 229 seconds
Antibacterial compound from Euchema spinosum originated from Tasikmalaya West Java against pathogen bacteria with TLC-bioautography
Get PDFStreptococcus mutans (Gram-positive) and Shigella dysenteriae (Gram-negative) are two types of pathogen bacteria. The use of synthetic antibiotics against both bacteria is known to impact the bacteria's resistance. E. spinosum from Tasikmalaya is a potential macroalgae as a source of an antibacterial compound for both bacteria. The research aims to determine the antibacterial metabolite compound from E. spinosum originated from Tasikmalaya against S. mutans and S. dysenteriae. The research was conducted through several stages, starting from phytochemical screening, gradual maceration using hexane, ethyl acetate, and methanol, determination of antibacterial activity, and TLC-bioautography. Phytochemical screening showed that both raw material and extracts contained alkaloids, flavonoids, and steroids. The result showed that hexane, ethyl acetate, and methanol extract could inhibit the growth of S. dysenteriae starting from a concentration of 400 µg/mL. However, only ethyl acetate extract can inhibit the growth of S. mutans, starting from a concentration of 20 µg/mL. The chromatogram of the hexane extract showed the presence of 6 spots, ethyl acetate extract showed 5, and the methanol extract showed only 4, resulted from the elution system, respectively. The TLC-bioautography against S. dysenteriae showed that there was the presence of three clear zones on the ethyl acetate extract, detected as flavonoid, and three clear zones on the methanol extract. The TLC-bioautography against S. mutans showed one clear zone on the chromatogram of ethyl acetate extract. According to the AlCl3 spray reagent confirmation test, the active compound was the flavonoid group
Effect of virgin coconut oil (VCO) on the physical stability of sweet potato leaf extract (Ipomoea batatas (L.) Lam) creams and antibacterial activity test against Staphylococcus aureus ATCC 25923
Get PDFVCO (virgin coconut oil) has benefits for skin health such as softening the skin, maintaining skin health, and protecting the skin from radiation and free radicals. VCO as one of the raw materials for making cream preparations can affect its physical stability. This study aimed to analyze the effect of VCO on the physical stability of sweet potato leaf extract creams and antibacterial activity test against Staphylococcus aureus ATCC 25923. The creams were made with five formulas namely base, extract cream 2%, and VCO 1%, 3%, 5% added to the extract cream 2% respectively. Physical stability test included storage for six weeks at room temperature. Stability parameters were organoleptic observation, homogeneity, pH, spreadability, adhesivity, and cream type. Statistical analysis was carried out with the Anova and Kruskal Wallis tests. The organoleptic test results of the cream extract showed a distinctive odor, green color, with semisolid and homogeneous texture. Increasing the concentration of VCO will increase the spreadability of extract cream but did not affect pH and adhesion. The conclusion of this study was that extract cream 2% without the addition of VCO was the most stable cream formulation. Besides that, all the cream formulas did not show antibacterial activity against Staphylococcus aureus ATCC 25923
Evaluation of glycemic index determination method
Get PDFIn Indonesia, determination of glycemic index (GI) was performed according to approved protocols prescribed by FAO (1998) and BPOM (2011); but, remarkable differences among these methods exist, primarily regarding the points of recommendation. This present work aimed to evaluate the technical steps of the protocol for determining GI between two protocols recommended by BPOM (2011) and FAO (1998). Ten healthy subjects (age 21-36 years old and body mass index (BMI) 18.5-24.9 kg/m2) were recruited for the study. The blood glucose was measured with repeated glucose trials, while the number of sampling points for the blood glucose test was also investigated. The range of GI for rice, wheat cookies, NS-cookies, HMT-cookies were 68 – 77; 55 – 60; 35 – 43; 35 – 41, respectively, using the combination of three different aspects between FAO and BPOM protocol. Noticeably, the difference in glucose trials did not cause significant variations to GI (n=10, p>0.05). Regarding statistical performance between methods, the Coefficient of Variance (CV) resulted from BPOM protocol (10 subjects, 5 sampling points) ranged 37 to 49%, being slightly higher compared to CV obtained from FAO protocol (7 subjects with triplicate glucose trials, 7 sampling points), i.e., 33% and 35%. The conclusive remark was noticed, that the most satisfying protocol for determination of GI was achieved using no less than two reference food trials, seven subjects, and seven blood sampling points
Self-nanoemulsifying drug delivery system (SNEDDS) of piroxicam: evaluation on anti-inflammantory activity in wistar rats
Get PDFPiroxicam is a non-steroidal anti-inflammatory drug (NSAID) that is commonly used for arthritis, gout, and other musculoskeletal disorders. Piroxicam is poorly soluble in water and according to the biopharmaceutical drug classification system (BCS) is classified as a Class II drug with good permeability but poor dissolution. The self-nanoemulsifying drug delivery system (SNEDDS) has been extensively employed to improve the dissolution and absorption of water-insoluble drugs within the gastrointestinal tract, leading to enhanced oral bioavailability and increased therapeutic effect of the loaded drugs. Therefore, the present study aims to evaluate the anti-inflammatory activity of piroxicam-loaded SNEDDS as compared to conventional piroxicam suspension that was observed in male Wistar strain rats. The SNEDDS was tailored from a mixture of oleic acid, tween 80, and propylene glycol. Twenty male Wistar strain rats (aged 2-3 months, weighed 150-250g) were selected and were divided equally into 4 different groups receiving 1% PVP, SNEDDS carrier, piroxicam suspension (1.8 mg/Kg BW), and SNEDDS piroxicam (1.8 mg/Kg BW). Acute inflammation was induced by a carrageenan-induced paw edema model where the carrageenan was injected sub plantar in the hind paw of the rats to induce edema. Several parameters including paw edema volume, AUC0-6, and percent anti-inflammatory effect, were measured to evaluate the anti-inflammatory activity experienced in each group. At the end of this study, the piroxicam SNEDDS group significantly demonstrated better protection from paw edema compared to the piroxicam suspension group (Ï<0.05), suggesting that SNEDDS may enhance the anti-inflammatory activity of piroxicam
Inhibitory activity of several extract of Piper betle Leaf against S. aureus
Get PDFA high number of infections from year to year require infectious diseases to get serious attention. The antimicrobial compound exploration must be continued to anticipate the development of infectious diseases. The purpose of this study was to find out in vitro antimicrobial activity of n-hexane, ethyl acetate, and ethanol fractions of Piper betle green leaves against S. aureus, and profiles of secondary metabolite compounds contained in these three extracts. The antimicrobial activity test was carried out by disk diffusion test of the fraction of n-hexane, ethyl acetate, and ethanol at a concentration of 6,25, 12,5, and 18,75 µg/disk. Detection of secondary metabolite content was done by the Thin Layer Chromatography method with stain-view reagents. The highest antimicrobial activity was found in the ethyl acetate fraction and was significantly different from the activity in the ethanol and n-hexane fractions. However, the antibacterial activity of all fractions was lower compared to the positive control of amoxiclav 30µg/disk. The phytochemical screening results of secondary metabolites of each fraction were shown that the n-hexane fraction contained alkaloids, terpenoids, flavonoids, polyphenols, and anthraquinone; the ethyl acetate fraction contained terpenoids, polyphenols, and anthraquinone; while the ethanol fraction contained alkaloids, terpenoids, polyphenols, and anthraquinone. Based on the test results, it is concluded that all fractions of Piper betle leaf extract had high antimicrobial activity; meanwhile, the ethyl acetate fraction had the highest activities among others. Each fraction was proven to have a different composition of secondary metabolites
The effect of propylene glycol and polyethylene glycol 400 on physicochemical properties of peel off mask of nanosilver using bioreductor Sweet Orange Peels (Citrus sinensis L. Osbeck)
Get PDFNanosilver (AgNPs) can be synthesized using plant extracts that safe, simple, and environmentally friendly. Sweet orange contains flavonoids and citric acid, which can be a bioreductor and capping agent in silver biosynthesis to increase antimicrobial activity. AgNPs are then dispersed in a gel for acne treatment through a peel-off mask preparation. Humectants provide moisture, prevent skin irritation and regulate the viscosity of the preparation. Propylene Glycol (PG) and Polyethylene Glycol 400 (PEG 400) are humectants combined to obtain good physicochemical properties of the preparation. This study aims to determine the character of AgNPs and the effect of humectant combinations on the physicochemical properties of peel-off mask preparations. AgNPs characterization was performed using UV-VIS Spectrophotometry, Particle Size Analysis, and Scanning Electron Microscope. The PG-PEG 400 combinations are F1 (0: 100%); F2 (25%: 75%); F3 (50%: 50%); F4 (75%: 25%) and F5 (100%: 0). The physical-chemical test for 28 days included organoleptic, viscosity, dry time, and pH. The biosynthesis results produced AgNPs with maximum absorption of nanoparticles at 435 nm, rod morphological shapes measuring 106 ± 10.6 nm, and PI 0.26 ± 0.06. Statistical analysis showed that the PG-PEG 400 combination significantly affected the viscosity, dispersibility, and dry time of the preparation but affected nothing to pH. The combination of PG-PEG 400 decreased the viscosity and increased the dispersibility of peel-off mask preparation. The higher concentration of propylene glycol caused the dry time of preparation to become longer. Formulas with PG-PEG 400 combination of 25%: 75% and 75%: 25% meet the requirements of viscosity, dispersibility, dry time, and pH and not significant changes during 28 days of storage at room temperature
