Transdermal drug delivery system (TDS) is not practically for delivery of materials whose final target is skin itself. Application topical agents generally offer many problems such as rashes, skin irritancy and burning sensation etc due to higher percutaneous absorption of drugs on the skin. Some conventional dosage e.g., gels and ointments which are often aesthetically unappealing, greasiness and...
Transdermal drug delivery is proving to be superior to the conventional oral delivery of drugs owing to its distinct virtues. But it has got its own limitations as well- inability to transport large molecules, inability to overcome the barrier properties of stratum corneum and many more. Using this route of drug delivery along with novel approaches can help to solve these problems. Formulating the...
IN VITRO ANTIBACTERIAL, ANTIOXIDANT, HAEMOLYTIC, THROMBOLYTIC ACTIVITIES AND PHYTOCHEMICAL ANALYSIS OF SIMAROUBA GLAUCA LEAVES EXTRACTS
Objective: To study the leaves of Simarouba glauca for their antibacterial, antioxidant, haemolytic, thrombolytic activities and to perform phytochemical evaluation. Methods: The three extracts (chloroform, methanol, ethyl acetate) of Simarouba glauca were screened for antibacterial activity against five pathogenic microorganisms by well diffusion method. In vitro antioxidant activity of extract w...
Antibiotic is one of the most important commercially exploited secondary metabolites produced by bacteria, fungi and Streptomyces and employed in a wide range. Most of the antibiotics used today are from the microbes. Bacteria are easy to isolate, culture, maintain and to improve their strain. Bacillus species being the predominant soil bacteria because of their resistant endospore formation and p...
Most of the new chemical entities coming out from High-throughput screening in drug discovery process are failing due to their poor solubility in the water. Poorly water-soluble drugs show many problems in formulating them in conventional dosage forms. One of the critical problems associated with poorly soluble drugs is too low bioavailability. The problem is even more complex for drugs belonging ...
The present article is a descriptive study of the performances of ethosomes and proniosomes as specialized delivery systems for transdermal drug delivery system. Vesicular systems, such as ethosomes and proniosomes are used in cosmetic and pharmaceutical products to encapsulate ingredients, to protect ingredients from degradation, to increase bioavailability, and to improve cosmetic performance....
Herbal medicine is gaining popularity once again and there is an increased interest in green medicine simply because it is considered as safe. Traditionally also plants and plant extracts were used to cure many diseases and disorders. However, before usage it is of utmost important to ensure its safety. The extract may be therapeutically very efficient but if it’s toxicity assessment is not wo...
VISUAL ESTIMATION AND SPECTROPHOTOMETRIC DETERMINATION OF TANNIN CONTENT AND ANTIOXIDANT ACTIVITY OF THREE COMMON VEGETABLE
Antioxidant activities of different vegetables Bitter gourd, Tomato and Spinach (Momordica charantia, Lycopersicon esculentum, Spinacia oleracea) were determined. In addition, rapid visual estimation of tannin content, total phenolic, tested for their free radical scavenging activity (FRSA) in the DPPH (1, 1-dephenyl- 2-picrylhydrazil radical) of those samples were assessed. A new technique was us...
DEVELOPMENT AND VALIDATION OF SPECTROPHOTOMETRIC METHOD FOR SIMULTANEOUS ESTIMATION OF GLICLAZIDE AND METFORMIN HYDROCHLORIDE IN BULK AND TABLET DOSAGE FORM BY SIMULTANEOUS EQUATION METHOD
A simple, rapid, accurate, precise, specific and economical spectrophotometric method for simultaneous estimation of Gliclazide (GLC) and Metformin hydrochloride (MET) in combined tablet dosage form has been developed. It employs formation and solving of simultaneous equation using two wavelengths 227.0 nm and 237.5 nm. This method obeys Beer’s law in the employed concentration ranges of 5-25 μ...
Traditional remedies and preparation used for the treatment of skin, or the folk preparations used for healing skin diseases are known to be as Cosmeceuticals and cosmetics. The desire of gook looking and to be beautiful gave a huge market for the cosmetics. This is not a new tradition for human to look good; it has been a long ancient follow through for both the sexes to be presentable by beauty....
