The deposition of a drug to its required destination is crucial for effective lung treatment. It is important to design a suitable formulation that delivers the active ingredient to the desired site and resists the natural cleansing mechanisms of the airways. Large porous particles used as active substance carriers appear to be the most effective option for lung drug delivery. The present article provides a basic overview of the mechanisms of deposition of dry inhalable powders and methods of their preparation and evaluation. Spray drying together with micronization and crystallization techniques are among the most used methods of preparation of the discussed particles. Besides, these techniques can be combined with other production processes (encapsulation, emulsification, etc.). The evaluation of the properties of particles suitable for pulmonary application is based on specific requirements for their density, porosity, shape, aerodynamic parameters, and deposition in the lungs, which can now be simulated on an accurate model of artificial lungs.

Preparation and Evaluation of Polymer-Based Ultrasound Gel and Its Application in Ultrasonography

Ultrasound imaging is a widely used technique in every health care center and hospital. Ultrasound gel is used as a coupling medium in all ultrasound procedures to replace air between the transducer and the patient’s skin, as ultrasound waves have trouble in traveling through air. This research was performed to formulate an inexpensive alternative to commercially available ultrasound gel as it is expensive and imported from other countries. Different formulations with different concentrations of carbopol 980 (CAR 980) and methylparaben were prepared with natural ingredients such as aloe vera gel and certain available chemicals that have no harmful effects on the skin. To justify the efficiency of the formulations; necessary physicochemical characteristics such as visual clarity, homogeneity, transparency, skin irritation, antibacterial activity, pH, stability, spreadability, conductivity, acoustic impedance, viscosity, and cost were evaluated. Moreover, a comparison study was also conducted with commercially available ultrasound gel that was utilized as a control. All samples showed excellent transparency and no microbial growth. S1 was the only formulation that met all of the requirements for commercial ultrasound gel and produced images that were similar to those produced by commercial ultrasound gel. So, this formulation could be used as an alternative to expensive commercial ultrasound gel for taking images in hospitals and medical centers.

Preparation and Evaluation of Polyherbal Hair Oil

The various products to enhance beauty and elegance to look young and charming. Cosmetics thus play a vital role in human life. Now a days, herbal cosmetic are widely used because of the Belief that they have fewer side effects and better safety. Hair is one of the primary parts of the body which Acts as a protective appendage. The objective of the present work is to develop a hair oil for general purpose (daily use) using various herbs. The formulated oil was evaluated for its organoleptic properties, acid value, Saponification value, refractive index, pH etc. All the parameters were found to be good and within the Standards.

PREPARATION AND EVALUATION OF BB CONCEALER CREAM CONTAINING NEEM OIL FOR ACNE TREATMENT

Acne vulgaris is a chronic dermatological inflammatory disease with symptoms like redness, comedones and blemishes appearing on face and neck. Propionobacterium acnes plays an important role in this disease. Neem oil, an ayurvedic, anti-bacterial medicine is non-comedogenic. Concealer is a type of cosmetic used to mask and camouflage blemishes and imperfections visible on skin and are available as liquid, balm, cream and stick. BB creams in cosmetics is termed as “beauty balm, blemish base, blemish balm” designed to serve as foundation, moisturizer and sunscreen all at once. The current study was to develop an aesthetic BB cream combining an anti-acne activity with concealing effect. Concentrations of upto 25 %w/w neem oil was prepared and evaluated for appearance, texture, pH, spreadability, antibacterial properties and in vitro release studies. All the formulations confirmed activity against P. acnes. Prolonged activity of neem oil observed at the end of 6 h as demonstrated in vitro
