Solid lipid nanoparticle is the forfront of the rapidly developing field of nanotechnology and as an alternative to other traditional colloidal carriers like liposomes, polymeric nanoparticles and emulsions as they have advantages like controlled drug release and targeted drug delivery with increased stability. Objective: Solid lipid nanoparticles (SLNs) consist of spherical solid lipid particles in the nanometer size range, which are dispersed in water or in an aqueous surfactant solution. SLN technology represents a promising new approach to deliver hydrophilic as well as lipophilic drugs. Due to their unique size dependant properly, lipid nanoparticles offer to devlop the new therapeutics. Method: The incorporation of drugs into nanocarriers offers a new prototype in drug delivery that could be used for several levels of drug targeting. Hence, solid lipid nanoparticles hold great promise for reaching the goal of controlled and site-specific drug delivery and hence have attracted the wide attention of researchers. Conclusion: The present review article focus on overview about the potential advantages, disadvantages, the excipients and all the different...

Glipizide is second generation Short acting sulfonylurea prescribed for treatment of type II diabetes Mellitus. It is with short biological half-life of 3.4 ± 0.7 hrs and metabolized in the liver and excreted in the urine largely as inactive metabolites. The clinical and pharmaceutical analysis of drug requires analytical procedures along with pharmacokinetic and pharmacodynamic data with stability study for any analysis of drug. In the present review we have compiled different published analytical methods for determination of glipizide in pharmaceutical methods. The table no 1 indicate Analytical method development and validation of single Glipizide drug by HPLC method; while table no 2 indicates Analytical method development and validation of glipizide with combination of other drugs by HPLC method. In the literature review table no 3 and 4 indicates Analytical method development and validation of glipizide as well as other drugs in combined forms by UV spectrophotometer. This literature review also involved tabulated information about various formulations available of glipizide along with their method of formulation and polymers used...

Psidium guajava is a small medicinal tree that is native to South America and Brazil is among the world’s top producers and most of the country’s production is destined for the food industry. It is popularly known as guava and has been used traditionally as a medicinal plant throughout the world for a number of diseases. It contains important phytoconstituents such as tannins, triterpenes, flavonoid: quercetin, pentacyclic triterpenoid, guajanoic acid, saponins, carotenoids, lectins, leucocyanidin, ellagic acid, amritoside, beta-sitosterol, uvaol, oleanolic acid and ursolic acid. It is one of the valuable plant in the Myrtaceae family. Psidium guajava which was reported the antibacterial, anti-diarrhoeal, antihyperglycemic, anti-malarial, anti-inflammatory, anti-cancer, antioxidant activity etc. The present review is an attempt to generate interest among the masses regarding its immense potential in preventing and treating several common...

Herbal medicines are in great demand in the developed as well as developing countries for primary healthcare because of their wide biological and medicinal activities, higher safety margins and lesser costs. Lawsonia inermis L. is commonly known as Henna or Mhendi and abundantly available in tropical and subtropical areas. Henna belongs to lythraceae, also known as the loosestrife family. Ancient history of India describes its diverse uses and also plays appreciable role in Ayurvedic or natural herbal medicines. Henna has been used cosmetically and medicinally for over 9,000 years. Currently, there is a renewed interest in henna due the wide range of its pharmacological activities, safety and availability. The present attempt is to review and compile updated information on various aspects of Lawsonia inermis (Linn), a plant used all over the world. It gives a complete view of its pharmacological actions such as analgesic, anti-inflammatory, antipyretic, antiarthritic, antibacterial, antifungal, antiviral, antimalarial, antidiabetic, abortifacient, hepatoprotective, antioxidant, anticancer, antifertility, antiulcer, diuretic, wound healing, protein glycation inhibitory, enzyme inhibitory, antitrypanosomal, anticoagulant, antisickling,...

Antibiotic efflux pumps appear a major component of microbial resistance to many classes of major antibiotics namely the tetracycline, the macrolides, and the fluoroquinolones. These are totally synthetic, amphiphilic compounds with no known ‘natural’ counterpart, antibiotic efflux appears sufficient per se to confer a medium or high level of resistance, defeating medically applicable treatments of the corresponding infections with these antibiotics. Antibiotic efflux may be found in association with other mechanisms, such as antibiotic inactivation, to confer high-level resistance on bacteria. In some respects, this phenomenon bears similarities with the cooperation of drug-extruding pumps and the cytochrome P450-based degradation pathways in enterocytes. An increasing knowledge about a variety of efflux pumps that are involved in MDR of pathogens, is an important challenge for current medicinal chemistry. The existence of antibiotic efflux pumps, and their impact on therapy, must now be taken fully into account for the selection of novel antimicrobials. The design of specific, potent inhibitors appears to be an important goal for the improved control of infectious diseases...
