Abstract

The use of drugs that are less soluble in water will become clinically less efficient, this is caused by the low penetration of the drug into the body. A microemulsion is a dispersion system such as an emulsion that can increase the solubility of drugs that are sometimes difficult to dissolve in water. Microemulsions have long-term stability, clear, transparent, and good penetration capabilities. In this study, a microemulsion formulation with active ingredients griseofulvin and virgin coconut oil was conducted as an oil phase. The resulting microemulsion evaluates physical stability during 35 storage days. The results showed that the microemulsion preparation remained stable during storage time without changes in color, odor, and consistency, while the pH and dosage viscosity experienced less significant changes. The consequences of the centrifugation test at 3700 rpm for 5 hours and freezing tests for 24 days showed stable preparation and cannot be separated. The diffusion test results obtained by FG2 had the largest permeation percentages of 3.6136%, FG3 2.8724%, and the smallest FG1 2.0477%.Keywords: microemulsion, griseofulvin, stability, diffusion test

Abstract

Solubility as a cause of ineffective active pharmaceutical ingredients (API) needs to be a concern. One of the solutions to increase the solubility by choosing active ingredients in the amorphous form. However, the amorphous form tends to be unstable because it has high Gibbs free energy and molecular mobility. To overcome those properties solid dispersion methods can be an answer. The dispersion of the amorphous form in the polymer is expected to prevent the transformation of API to crystal stable form. The solid dispersion (SD) resulted needs for physicochemical characterization to prove the ability of SD to maintain the amorphous form. Therefore, the physicochemical properties of the amorphous solid dispersions (ASDs) have to analyze there in any interactions that are able to occur between the drug and the polymer. Also for evaluate the stability of the ASDs within a certain period. In the article presents, some articles related with ASDs and its characterization will studying, include several product on the market as example. The number of literature used in this article is 69 articles.Keywords: Solubility, amorphous for, solid dispersion, characterization ASDs.

Abstract

Warfarin is an oral anticoagulant that has been widely used and has strong efficacy, but the use of warfarin is still a concern because of its narrow therapeutic index which cause interactions when co-administration with drugs, herbs or food. This interaction can affect the pharmacokinetics and pharmacodynamics of warfarin and the most fatal effect from warfarin interactions is bleeding. In this review article data on warfarin-herbs interactions were collected based on pharmacokinetic parameters (AUC0-∞, Cmax, T1/2, Cl/F, and V/F), while pharmacodynamic parameters (International normalized ratio (INR), platelet aggregation, AUC INR and Protombine Time). As a result some herbs had significant interactions with warfarin. Herbs that affect warfarin pharmacokinetic were Danshen gegen, echinacea, St. John's wort and caffeine and herbs that affect pharmacodynamic were policosanol, Ginkgo biloba, cranberry, St. John's wort, ginseng, pomegranate, Psidium guajava and curcumin, so co-administration warfarin with herbs need to be considered.Keywords: Warfarin, Interactions, Herbs, Pharmacokinetics, Pharmacodynamics

Abstract

Many techniques can be used to improve drug solubility, which is the development of the liquisolid technique. This technique has a mechanism for increasing the surface area of the drug as well as wetting from the addition of non-volatile solvents resulting in a lower surface tension and contact angle, so the solubility and drug release very increases. Liquisolid tablets show a lower contact angle compared to the conventional tablets. The liquisolid technique approach is also promising because the process is simple in making low production costs and allows the manufacturing industry, including non-volatile solvents, fillers, dryers, and disintegrants. Liquisolid characterized by specific instruments such as powder x-ray diffraction (PXRD), Fourier transforms infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and scanning electron microscope (SEM). Several liquisolid techniques are described in this review. The liquisolid technique is proven and able to change the physicochemical properties of active pharmaceutical ingredients, especially the solubility, drug release, and stability of the formula so that this technique can be a solution for class II and IV BCS pharmaceutical active drug classes.Keywords: Active Pharmaceutical Ingredients, Contact Angle, Solubility, Drug Release, Stability, Liquisolid Technique

Abstract

We developed a simple and rapid method for the determination of abemaciclib in human serum using supported liquid extraction (SLE) method for pretreatment and LC-MS/MS. Abemaciclib was extracted using SLE method with methyltert-butyl ether (MTBE) as elution buffer, and analyzed by LC-QTOF MS system, LCMS9030 (Shimadzu). Abemaciclib and fluconazole (internal standard) were detected with ESI spray in positive ionization mode, and the transition were set at 507.3/393.1629 for abemaciclib and 307.1/220.0677 for fluconazole. The retention times of abemaciclib and fluconazole were 2.76 and 2.98 min, respectively, and good linearity was obtained from 20–1,000 ng/mL for abemaciclib. The regression equation (weight = 1/x2) describing the calibration curve in human serum was y = 0.0196 x – 0.056 (R2 = 0.999), where y is the peak area ratio of abemaciclib against the IS and x is the nominal concentration of abemaciclib. The intra- and inter-assay accuracy varied between -4.3–1.7%, and the precision varied between 0.90–6.19%. The mean recovery rate of abemaciclib was 87.7 ± 4.3%, and the mean matrix factor was 1.00 ± 0.083. Our method offers speed and simplicity of sample preparation, which is one of great advantages in the analysis of clinical specimens. We believe that the present method will contribute to establishing a methodology for determining the optimal dose of abemaciclib for individual patients. Key words: abemaciclib, SLE, supported liquid extraction, quantification

Abstract

The correlation between the high content of selenium (Se) in plasma and the low prevalence of cardiovascular disease has been published in previous epidemiological studies. The content of Se in the plasma is determined by daily intake. A preliminary surveillance of Se content of several plants showed that the seeds of jengkol (Pithecellobium lobatum Benth.) has the highest concentration of Se. This study aims to develop a pharmaceutical formulation of Se supplement for adjuvant therapy of cardiovascular disease. The jengkol seeds was made into film coated tablets with a wet granulation method. Optimization of the core tablet formula was carried out with variations of binder concentration and coating material. Evaluation was carried out on uniformity of size and weight, disintegration time, hardness and friability. The content evaluation was carried out including the levels of Se, water content, ash, fat, protein, carbohydrate and crude fiber. The results showed that the F3 had the lowest friability and highest hardness. The coating of tablets using PVA has covered the smell of jengkol seed. The evaluation results showed that film coated tablets contained the Se level content of 0.074 ± 0.004 µg/g, water content of 2.19%, ash content of 1.88%, fat content of 0.89%, protein content of 0.66%, carbohydrate content of 94.38% and crude fiber content 1.79%. The results showed that the jengkol seed film coated tablet formulation could be used as a supplement in additional therapy for cardiovascular disease.Keywords    : Pithecellobium lobatum, film coated tablet, herbal supplement, selenium
