BACKGROUND DLBS1442, a proprietary and standardized semipolar bioactive extract of the fruit Phaleria macrocarpa, is preclinically proven to have anti-inflammatory properties. The current clinical study evaluated the efficacy and safety of DLBS1442 in alleviating symptoms of premenstrual syndrome and primary dysmenorrhea. METHODS This was an open study(More)
The medicinal value of earthworm has been widely known since the history of Asian ancient medicine. This present study aims to determine the mechanism of action and effect of a standardized extract of Lumbricus rubellus named as DLBS1033. The fibrinogen degradation, antiplatelet aggregation, and ex vivo antithrombotic assay using human blood were performed(More)
BACKGROUND DLBS3233 is a standardized extract combination containing Lagerstroemia speciosa and Cinnamomum burmannii. The effect of DLBS3233 on glucose uptake, adiponectin secretion, and insulin signaling was examined in this study. METHODS 3T3 Swiss albino preadipocytes and adipocytes were used to investigate gene expression detected using the reverse(More)
INTRODUCTION The present study was conducted to compare the bioavailability of two candesartan cilexetil 16 mg tablet formulations (test and reference formulations). MATERIALS AND METHODS This study was a randomized, single- blind, two-period, cross-over study which included 24 healthy adult male and female subjects under fasting conditions. The(More)
PURPOSE The present study was conducted to evaluate whether the bioavailability of pregabalin capsules 150 mg manufactured by PT Dexa Medica was equivalent to the reference formulation. METHODS This was a randomized, open-label, two-period, two-sequence, and crossover study under fasting condition, with a 1-week washout period. Plasma concentrations of(More)
DLBS1033 is a bioactive protein fraction isolated from Lumbricus rubellus that tends to be unstable when exposed to the gastrointestinal environment. Accordingly, appropriate pharmaceutical development is needed to maximize absorption of the protein fraction in the gastrointestinal tract. In vitro, ex vivo, and in vivo stability assays were performed to(More)
This study assessed the gastric acid antisecretory effect of DLBS2411 fractionated from Cinnamomum burmannii. Hydrogen potassium adenosine triphosphatase (H(+)/K(+) ATPase) activity and its gene expression were observed, and the antioxidant activity of DLBS2411 was also investigated. Treatment of DLBS2411 decreased the level of H(+)/K(+) ATPase messenger(More)
BACKGROUND The present study was conducted to compare the bioavailability of two bisoprolol fumarate 5 mg film-coated tablet formulations (test and reference formulations). PATIENTS AND METHODS This study was a randomized, single-blind, two-period, two-sequence crossover study that included 18 healthy adult male and female subjects under fasting(More)
A lectin-like protein of unknown function designated as LSMT was recently discovered in the edible mushroom Agaricus bisporus. The protein shares high structural similarity to HA-33 from Clostridium botulinum (HA33) and Ricin-B-like lectin from the mushroom Clitocybe nebularis (CNL), which have been developed as drug carrier and anti-cancer, respectively.(More)
We report novel pharmaceutical salts of an anti-hypertensive drug carvedilol (CVD) with pharmaceutically acceptable salt formers, including oxalic acid (OXA), fumaric acid (FUMA), benzoic acid (BZA), and mandelic acid (MDA) via conventional solvent evaporation technique. The pKa difference between CVD and selected acids was greater than 3, thus suggesting(More)
