Abstract

Captopril is an antihypertensive class of Angiotensin-Converting Enzyme Inhibitor (ACEI) used as one of the treatment of hypertension. Low bioavailability and short half-life of captopril caused side effects on gastrointestinal tract, thus it can be prepared into hollow microspheres. Hollow microspheres is spherical microparticles with 1-1000 µm hollow nucleus. Many factors influence the preparation of hollow microspheres including the amount of hydroxypropyl methylcellulose (HPMC) polymer and stirring time. In this study we investigated the best composition of the number of HPMC and stirring times which can produce captopril hollow microspheres with entrapment efficiency (EE), buoyancy, and optimum particle size. Hollow microspheres captopril was prepared using a non-aquoeous solvent evaporation method. The result was captopril hollow microspheres with 25 mg HPMC and 2 hours of stirring can produce an entrapment efficiency (EE) 97,796%, buoyancy 86,747% and particle size 205,655 µm. The yield hollow microspheres captopril 91.903% ± 2.547 with spherical shape, uneven surface morphology and hollow core. The results of FT-IR analysis showed that there was no interaction between the drug and the polymer used in the formulation.

Abstract

Moringa Gum is a gum derived from the Moringa oleifera tree which can be used as a stabilizer, binder, mucoadhesive, disintegrant, sustained release and controlled release matrix. Diltiazem Hydrochloride is a drug with low bioavailability and has a low plasma half-life (3-4 h). The bioavailability and half-life of Diltiazem Hydrochloride can be improved by buccal film mucoadhesive formulation. In this study, a combination of natural polymers, namely Moringa Gum and glycerin plasticizer, was used to produce a film with swelling, mucoadhesive properties and also good folding resistance. This studi was conducted to optimize Moringa Gum and glycerin to see the release profile of Diltiazem Hydrochloride in the muchoadhesive buccal film. The formulation was carried out using the solvent casting method with optimization using a design expert while verification of the optimum formula was carried out using a one sample t test with a confidence level of 95% with the condition that the significance was p>0,05. The optimum formula obtained from the amount of polymer Moringa Gum is 75 mg and the plasticizer glycerin is 5 mg. The results of the FTIR test showed that there was no interaction between Diltiazem Hydrochloride and the moringa gum polymer. As for the release test results, the release percentage was 99.69% by following the Higuchi release model. This study concludes is that buccal film was successfully prepared using a combination of moringa gum and glycerin with its potential to increase the bioavailability and half-life of Diltiazem Hydrochloride by prolonging the contact time and controlling the release.

Abstract

Hypertension is a condition while blood pressure is increasing. The normal value of blood pressure is <120/80 mmHg. One of the drugs used to reduce blood pressure is captopril. Captopril has a short half-time, so it requires repeated administration that allows fluctuations. To solve this shortcoming, an approach was carried out using a controlled delivery system, hollow microspheres. The purpose of this research is to optimize and determine the amount of Hydroxypropyl Methylcellulose (HPMC) and Ethyl Cellulose (EC) polymers that can produce the optimum formula. Optimization is done using the factorial design method. The response that will be observed in this research is the value of entrapment efficiency, buoyancy, and particle size. The optimum formula was obtained in the combination of HPMC and EC amounts in captopril hollow microspheres are 75 mg HPMC and 200 mg EC.

Abstract

Avobenzone and octinoxate are often used as a combination of organic UV filters in sunscreen. At high exposure to UV light, these UV filters can be degraded so that their sunscreen’s effectiveness is reduced. Several studies reported that the combination of plant extracts with synthetic UV filters could increase sunscreen's SPF. Mango leaves contain high levels of flavonoids and in several studies have been shown to have photoprotective activity with good Sun Protection Factor (SPF) values. The Manalagi mango plant is a type of mango that is widely planted in yards, so it's easy to get the raw materials. This study aims to determine the effect of manalagi mango leaf extract with a concentration of 1, 3, and 5% on the physical quality (pH, viscosity, spreadability) and sunscreen activity (SPF, %TE, %TP) of sunscreen emulgel containing avobenzone and octinoxate. This study showes that increasing the concentration of manalagi mango leaf extract reduced the pH and viscosity of the preparation, and significantly increased the spreadability of all formulas. Besides that, it can also increase the SPF value and decrease the %TE and %TP values. The emulgel formula that had the highest sunscreen activity was F3 with an extract concentration of 5%, had an SPF value of 30.597 ± 0.600, %TE 0.0001 ± 0.0001, and %TP 0.0038 ± 0.0016.

Abstract

Excessive exposure to ultraviolet radiation can cause various skin problems. This problem can be prevented by using cosmetic products that contain sunscreen ingredients. In this study, optimization of the combination of quercetin and avobenzone in sunscreen spray lotion was carried out using the factorial design method. The aim of this study was to determine the optimum concentrations of avobenzone and quercetin which could provide optimum physicochemical properties and effectiveness of in vitro sunscreen spray lotion. The formula is made with a low concentration of 0.5% quercetin and an upper limit of 3%, while avobenzone has a low level of 2% and an upper level of 4%. Based on the research that has been done, the optimum formula prediction is obtained with a concentration of 0.934% quercetin and 4% avobenzone. The optimum formula has a desirability value of 0.958 and shows the predicted value of software to have an SPF in vitro value of 33.311, a %TE 0.058%, a %TP 0.002%, a viscosity of 10 dPa.s, and a pH of 5.689. The results of the analysis using the t-test (one sample t-test) with a 95% level of confidence between the software prediction results and the observation results showed a value of > 0.05, which means that there was no significant difference between the software prediction results and the observation group.

Abstract

HAMIN® is a self-emulsifying base composed of a mixture of hydrogenated palm kernel oil and hydrogenated palm kernel stearin. This formulation not only enhances the aesthetic quality of products but also simplifies the manufacturing process, as it eliminates the need for additional emulsifying agents to form a stable cream. Due to these properties, HAMIN® is considered highly suitable for the development of both pharmaceutical and cosmetic formulations. Despite its potential applications, no prior research has investigated the optimal ratio of HAMIN® palm fat base to distilled water distilled waterrequired to achieve desirable physical characteristics and drug release properties in cream formulations. Therefore, this study aims to determine the optimum composition of HAMIN® palm fat base and distilled water for the formulation of diphenhydramine hydrochloride cream. The optimization process was conducted using the simplex lattice design (SLD) method, a statistical approach commonly employed to evaluate and optimize multicomponent formulations. The experimental results demonstrated that increasing the concentration of HAMIN® palm fat base had a dominant effect on enhancing the pH, viscosity, adhesion, and stability of the cream. Conversely, a higher concentration of distilled water significantly improved spreadability, extrudability, and drug release flux. These findings indicate that the selection of base composition plays a crucial role in determining the overall performance of the cream formulation. The optimal formulation, as determined through SLD analysis, consisted of 41.667% HAMIN® palm fat base and 48.333% distilled water, achieving a desirability index of 0.649. This composition represents the most balanced formulation in terms of physical stability and drug release, making it a promising candidate for further pharmaceutical and cosmetic applications.
