Ashwagandha (Withania somnifera Dunal) is one of the most commonly used medicinal plants in Indian Medicine for varied range of physical and psychological ailments. It is an important medicinal plant that has been used in Ayurvedic and indigenous medicine for over 3,000 years. Ashwagandha roots are a constituent of over 200 formulations in Ayurveda, Siddha and Unani medicine, which are used in ...

A binder holds powders together to form granules and also provides the cohesiveness required for binding of the granules under compression to form a tablet. Some natural excipients are currently available for pharmaceutical formulation. Aim of this study was to isolate the mucilage from different plants and to evaluate them as a binder. Here an effort was made to investigate the efficacy of muc...

High-amylose corn starch, that contains 70% of amylose chains and 30% of amylopectin, has been used to obtain substituted amylose (SA) polymers. Tablets have been prepared by direct compression, i.e. dry mixing of drug and SA, followed by compression, which is the easiest way to manufacture an oral dosage form. Until now, their controlled-release properties have been assessed only by an in vitr...

INTRODUCTION Inquiries from healthcare providers and patients about the gluten and aluminum content of Synthroid® (levothyroxine sodium tablets) have increased. The objective of this study was to measure and evaluate the gluten content of the raw materials used in the manufacturing of Synthroid. Additionally, this study determined the aluminum content in different strengths of Synthroid tablets...

The sensitivity and spatial resolution of hyperspectral imaging instruments are tested in this paper using pharmaceutical applications. The first experiment tested the hypothesis that a near-IR tunable diode-based remote sensing system is capable of monitoring degradation of hard gelatin capsules at a relatively long distance (0.5 kilometer). Spectra from the capsules were used to differentiate...

Pharmaceutical oral dosage forms are used in this paper to test the sensitivity and spatial resolution of hyperspectral imaging instruments. The first experiment tested the hypothesis that a near-infrared (IR) tunable diode-based remote sensing system is capable of monitoring degradation of hard gelatin capsules at a relatively long distance (0.5 km). Spectra from the capsules were used to diff...

The work aimed to determine the levels of hypericins expressed as hypericin in the herbal substance of St. John's wort, in capsules and tablets containing the extract of St. John's wort, tablets containing powdered herb and in tincture and juice from fresh St. John's wort, by HPLC method with spectrophotometric detection. In addition, the amount of hypericins in the infusion prepared from St. J...

In archaeology, the discovery of ancient medicines is very rare, as is knowledge of their chemical composition. In this paper we present results combining chemical, mineralogical, and botanical investigations on the well-preserved contents of a tin pyxis discovered onboard the Pozzino shipwreck (second century B.C.). The contents consist of six flat, gray, discoid tablets that represent direct ...

The aim of this study is to evaluate the adhesion ability of okra gum, which is gaining popularity as a tablet binder. For this purpose, gum was extracted from okra pods, and the binding strength of different concentrations (1%, 3%, and 5%) was determined quantitatively. Additionally, naproxen sodium tablets were prepared by using okra gum as a binder and were evaluated for their properties inc...

The deformation mechanism of pharmaceutical powders, used in formulating directly compressed matrix tablets, affects the characteristics of the formed tablets. Three polymers of different deformation mechanisms were tested for their impact on theophylline directly compressed tablets namely Kollidon SR (KL SR, plastic deformation), Ethylcellulose (EC, elastic deformation) and Carnauba wax (CW, b...
