OBJECTIVE: Zinc chloride is an important inorganic compound used as a source of zinc and has other numerous industrial applications. Unfortunately, it lacks reliable and accurate physicochemical, thermal, and spectral characterization information altogether. Hence, the authors tried to explore in-depth characterization of zinc chloride using the modern analytical technique. MATERIALS AND METHODS: The analysis of zinc chloride was performed using powder X-ray diffraction (PXRD), particle size distribution, differential scanning calorimetry (DSC), thermogravimetric analysis/differential thermogravimetric analysis (TGA/DTG), ultraviolet-visible spectroscopy (UV-vis), and Fourier transform-infrared (FT-IR) analytical techniques...

Tablets have been choice of manufacturers over the years due to their comparatively low cost of manufacturing, packaging, shipping, and ease of administration; also have better stability and can be considered virtually tamper proof. A major challenge in formulation development of the tablets extends from lower solubility of the active agent to the elaborated manufacturing procedures for obtaining a compressible granular material. Moreover, the validation and documentation increases, as the numbers of steps increases for an industrially acceptable granulation process...

INTRODUCTION: The majority of drugs obtained through synthesis and development show poor aqueous solubility and dissolution velocity, resulting in reduced bioavailability of drugs. Most of these problems arise from formulation-related performance issues, and an efficient way to overcome these obstacles and to increase dissolution velocity is to reduce the particle size of drug substances to form drug nanosuspensions. MATERIALS AND METHODS: Danazol nanosuspensions were prepared by wet milling (WM) and high-pressure homogenization (HPH) methods...

BACKGROUND: To formulation and development of plasma volume expander (PVE) by using natural and modified starch from Solanum tuberosum. The function of blood circulation is to provide the needs of the body tissues and to maintain an appropriate environment in all tissue fluids of the body for the optimal survival and functions of the cells. Rapid restoration of the blood volume is necessary to decrease reduction in the amount of the blood. The PVEs are isotonic colloidal solutions, act by increasing the osmotic pressure of the intravascular compartment, which leads to the influx of the interstitial fluids through the capillary pore which, in turn, leads to the increase in the volume of the blood...

INTRODUCTION: The potent antifungal agent amphotericin B (AmB) is not freely soluble in water. The clinical use of AmB is limited by nephrotoxicity and poor water solubility. Polyamidoamine (PAMAM) dendrimer offers an identical carrier for drug binding that has the capacity to attach and discharge drugs in numerous ways. MATERIALS AND METHODS: In this research work, we explored the potential of PAMAM dendrimers to improve the solubility of AmB. RESULTS AND DISCUSSION: The experimental results indicated that the solubility of AmB was greatly enhanced in the presence of PAMAM dendrimer solutions...
