Research on the activity of Phyllanthus niruri Linn, Typhonium flagelliforme (Lodd.) Blume and Piper crocatum have been conducted and showed various immunomodulatory activity. This study aims to investigate the immunomodulatory activity of the combination of the ethanolic extracts of Phyllanthus niruri Linn, Typhonium flagelliforme (Lodd.) Blume, and Piper crocatum by determining its macrophages phagocytic index and macrophages phagocytic capacity. Therefore, such a combination could be an alternative drug to increase immune response. In this study, the extraction procedure was carried out through maceration by using an ethanolic solvent. Combinations of herbs ethanol extract were varied in four groups of combination, at three different concentrations of 1 μg/ml, 10 μg/ml, and 100 μg/ml for each group. Macrophages were isolated from the peritoneum cavity of male mice (Mus musculus), and its phagocytic activity was quantified through the Leijh method (1986). The phagocytic index and phagocytic capacity of macrophages were determined by using latex beads as a trigger of phagocytosis and compared with negative controls of media, DMSO, and four groups of ethanolic extract combinations in different concentrations. The results indicate that all of combination group ethanol extract with a concentration of 10 μg/ml was significantly (p<0.05) optimum activated phagocytic index. Therefore the combination of Phyllanthus niruri Linn, Piper crocatum, and Thyphonium flagelliforme (Lodd.) Blume ethanolic extract might be prospective to increase nonspecific immune response.

Pharmacists and pharmaceutical personnel need to support improving the people’s quality of life during the covid-19 outbreak by providing pharmaceutical services, one of which is the Drug Information Service (PIO). Many regions in Indonesia, including DKI Jakarta, have placed large-scale social restrictions since March 2020. In connection with that, the Department of Pharmacy of Atma Jaya Catholic University of Indonesia (PSFUAJ) organized an online PIO program. This program aimed to provide the service of Covid-19 drug-related information and education to the community. The PIO was carried out from April to July 2020 via whatsapp, email, and telephone. In addition, health education was provided through e-flyers, published on Instagram @pio_farmasi_uaj. Eighty percent of the questions were submitted via whatsapp, while the rest was sent via email. Most of the questions submitted (80%) were categorized into self-edication. Further examination shows that the common questions were related to drug choice (27.78%). These data indicate that most questioners tend to provide self-medication first and that they will only see a doctor if they have not recovered or experienced any improvement. PSFUAJ will continue running this program and disseminating this program to a broader audience.

Introduction: Indonesia is a tropical country with high temperatures and humidity. Poor personal hygiene can trigger bacteria to grow and multiply. According to research, bacteria that are usually found in skin and hair including Staphylococcus aureus (37%), followed by Escherichia coli (17%). Use of antibacterial hairspray is expected to inhibit the growth of pathogenic bacteria on the surface of the scalp and hair. Using natural ingredients, i.e., cherry (Muntingia calabura L.) leaves, in the form of antibacterial hairspray preparations, is expected not to irritate the scalp, be more eco-friendly, and the raw materials are easily obtained. Methods: The preparation of cherry (Muntingia calabura L.) leaves extract was carried out by maceration method with 70% ethanol (simplisia : solvent = 1:10). Furthermore, the extract was then evaluated for phytochemical content, formulation optimization, and antibacterial activity. Afterward, formulation and preparation, and lastly, its evaluation in the form of an organoleptic test, pH test, viscosity test, homogeneity test, spreadability test, adhesion test, and product stability test. Results: The results of phytochemical screening of flavonoid compounds and tannins from cherry (Muntingia calabura L.) leaves extract resulted in a positive reaction. The minimum inhibitory level of cherry (Muntingia calabura L.) leaves extract against Staphylococcus aureus and Escherichia coli bacteria was 40 mg/ml. Cherry (Muntingia calabura L.) leaves extract was then formulated into hairspray dosage forms with different concentrations of extract in Formula A (0.1%), Formula B (0.3%), and Formula C (0.5%).

The effervescent tablet is an alternative dosage form to deliver the active pharmaceutical ingredients or natural products for therapeutic effects. Moreover, this dosage form is also used in the food industry for nutritional drinks. The tablet is preferred because of its practicality, improve water solubility, refreshing taste, and more easily absorbed than the conventional tablet. Tablet’s water dissolving time in the medium will affect the rate and amount of active ingredients. The disintegrating time of effervescent tablets is affected by the concentration of both acid and base elements, the tablet binder’s concentration (PVP), the interaction between citric acid and tartaric acid, and the concentration of the base element, the water content over the tablet, and the lubricant’s variation. The acid will affect the disintegration time however its imbalance will decrease the freshness. Therefore, an optimal balance of the base and acid element is required to make an effervescent tablet with a good disintegration time and an appropriate refreshing taste.

The Indonesian government recommended sunbathing for 15 to 30 minutes in the morning to deal with the Covid-19 pandemic. Exposure to sunlight will activate the formation of vitamin D, which the body needs for defense against Covid-19 infection. However, excessive sun exposure will cause skin problems, including psoriasis, sarcoidosis, sunburn to skin cancer. One of the protections against sun exposure is the use of sunscreen. Sunscreen protects the skin from UV exposure by two mechanisms, namely, absorbing UV rays or reflecting UV rays. Currently, many sunscreens are developed with active substances derived from nature in various dosage forms. Sunscreen protection is stated using a photoprotector claim in the form of an SPF value or other supporting claims. This SPF value can be claimed using in vivo test, which previously could be predicted by on paper and in vitro approaches. Sunscreen safety is carried out by ensuring that the raw materials used comply with the requirements and penetration tests.

Review: Metode Peningkatan Kecepatan Disolusi Dikombinasi Dengan Penambahan Surfaktan: Review: The Different Methods of Enhancing Dissolution Rate by the Present of Surfactant Sagala, Reynelda Juliani

Dissolution and solubility rates are very important parameters in designing a pharmaceutical dosage form, especially for oral drug administration. Oral drugs that have low dissolution rates often require high doses loading to improve the absorption and effectiveness in order to achieve therapeutic concentration. The increasing of drug dose is a less safe alternative solution, therefore researchers have developed physics, chemistry, and other modification in order to increase dissolution rate. These methods such as salt formation, prodrug formation, particle size reduction (micro-crystallization), co-grinding, crystal modification, micellar solubilization and complex formation, solid dispersion and self emulsifying. This review paper will focus on different methods that will be compared with the present of surfactant in these methods. The present of surfactants was able to overcome the limitation of each methods with a mechanism for reducing surface tension, micellar formation, reducing contact angle and increasing of wetting behaviour. Therefore, the present of surfactant in modification of drug dosage form could be considered to increase dissolution rate in order to achieve therapeutic effect.
