Excessive drug therapy, environmental pollutants, hepatic cancer and alcoholic intoxicants are the main causes of liver disorders. The hepatic disorders/toxicity can occur by several mechanisms like cytochrome P450 activation, lipid peroxidation, induction of nitric acid synthase, mitochondrial dysfunction, activation of pro-inflammatory mediators and bile acid-induced liver cell death. In spite of consistent human effort and drug discovery, the modern drug has very little to offer. (Prunus armeniaca) is commonly known as Khubani or moon of the faithful or Egg of the sun, which is used as folk medicine in traditional Indian medicinal system as well as worldwide medicinal system, belongs to the family Rosaceae. Prunus armeniaca fruit is the rich source of vitamin, carbohydrate, thiamine, niacin, iron, organic acids, phenols and volatile compounds viz. benzaldehyde, esters, norisoprenoids, terpenoids and minerals. The seed of Prunus armeniaca contain very small amount toxic hydrogen cyanide amygdalin, present in bitter prunus armeniaca kernels which are prescribed as anticancer drug, in asthma, cough and constipation. Prunus armeniaca is having some reported activities like anticancer,...

Background: Dolutegravir and Rilpivirine are two antiretroviral drugs that have been approved for the treatment of HIV Infection. An error-free, accurate, precise and valid reverse-phase liquid chromatography method was developed for the quantitation of Dolutegravir and Rilpivirine in its bulk form as well as in combined dosage form by forced degradation studies. Methods: Chromatographic separation of these two drugs Dolutegravir and Rilpivirine, was achieved with an INERTSIL ODS C18 (250 × 4.6 mm, 5 μm) reverse-phase analytical column with a 10 min analytical run time using a mixture of 0.1% OPA: Acetonitrile in the ratio of (60:40 v/v) as mobile phase. The mobile phase was streamed at a flow rate of 1.0 mL min-1 with a column temperature of 250 °C and detection wavelength was carried out at 230 nm. The retention time was found to be 3.4 min for Dolutegravir and 4.3 min for Rilpivirine. Results: The linearity limit of Dolutegravir and Rilpivirine was found to be in the range of 0.999 and 0.999. The method validation was...

Microsponges are novel drug delivery systems made up of cross-linked spongy, polymeric, porous, spherical microspheres particles which vary in size from 5-300 μm. This delivery system as the advantage of producing controlled release formulations of poorly soluble drugs. It increases drug stability, reduces side effects and modifies drug release profiles making it a versatile drug delivery vehicle. These active micro sponges can entrap a wide variety of substances and be incorporated into formulations, such as capsules, gels, liquids, creams and powders and share a broad package of benefits. This article presents a broad review of Micro sponges delivery system (MDS), discussing its characteristics, benefits, different preparation methods (Liquid-Liquid Suspension Polymerization, Quasi-Emulsion Solvent Diffusion) and release mechanisms. It also covers different characterization parameters like particle size, size distribution, morphology, surface topography, loading efficiency, production yield, compatibility studies, true density, in-vitro release studies and MDS systems applications in oral, topical cosmetics bone and...

Zingerone is an active phenolic acid and the least pungent component of Zingiber officinale. It is known to exhibit different pharmacological properties which include anti-inflammatory, antioxidant, anticancer and antimicrobial activities. But, so far there has been no information available on the role of zingerone in experimental breast carcinogenesis. The objective of this experiment is to untwine the anticancer qualities of zingerone against dimethylbenz (a) anthracene (DMBA)-incited mammary carcinogenesis. To achieve this goal, female Sprague-Dawley rats were arbitrarily classified into six groups. Group 1 was notified as the control, groups 2-5 were given a single dose of DMBA (25 mg/kg b.wt, subcutaneously) in the 4th week. Along with DMBA, groups 3 (initium), 4 (post-initium) and 5 (entire period) rats received zingerone (20mg/kg b.wt. p.o) every day in different time periods during the experimental period of 16 weeks. Group 6 rats received 20 mg/kg b.wt. of zingerone alone. Cancer-bearing animal mammary tissue when evaluated by western blot showed increased immune expression patterns of ER, PR, HER2/ neu, cyclin D1 and also...

One of the major barriers in the development of oral dosage form is poor solubility. Poor water solubility obstructs drug bioavailability and decreases its pharmaceutical development. Many drugs are in the pipeline to enhance solubility to formulate dosage form to be taken by the most preferred route of administration that is the oral route. Etodolac is nonsteroidal anti-inflammatory drug having a wide spectrum of activities but belongs to BCS class II. The attempt has been made in this work to improve solubility by forming ternary inclusion complexes of Etodolac with PVP K30 and β-Cyclodextrins. The ternary inclusion complexes were prepared by the physical mixing method and kneading method. The prepared complexes were analyzed by different analytical techniques comprising differential scanning calorimetry, infrared spectroscopy and solubility study. Special emphasis was given on the solubility evaluation of drugs and complexes. Based on observations and results, one can easily conclude about the usefulness of the complexation technique for the enhancement of...
