Solid lipid nanoparticles (SLN) are aqueous colloidal dispersions, the matrix of which comprises of solid biodegradable lipids. They are introduced in 1990 as an alternative carrier system to traditional colloidal carriers, such as emulsions, liposomes and polymeric micro- and nanoparticles. SLN combine advantages of the traditional systems but avoid some of their major disadvantages. They exhibit...
Pelletization process first came into existence way back during the 1950s, when the first product was introduced to the market. These pelletized dosage forms have gained popularity considerably from then because of their distinct advantages, such as ease of capsule filling because of better flow properties of the perfectly spherical pellets; enhancement of drug dissolution; ease of coating; sustai...
Plants have been one of the important sources of medicines since the beginning of human cultivation. There is a growing demand for plant based medicines, health products, pharmaceuticals, food supplements, cosmetics etc. A review of chemical constituents present in various parts of Glycyrrhiza glabra and their pharmacological actions is given in the present article. Glycyrrhiza glabra Linn, is a c...
Incorporation of drugs into non-ionic surfactant vesicles (niosomes) during their manufacture affords a possible method of achieving controlled release. The aim of this study is to formulate niosomes as carriers for delivery of diclofenac sodium (DCS). Niosomes are prepared with a series of sorbitan monoesters (Span 20, 40, 60, and 80) and sorbitan tri-oleate (Span 85) and co-surfactants of polyox...
RP-HPLC METHOD FOR SIMULTATANEOUS DETERMINATION OF AMLODIPINE BESYLATE, VALSARTAN, TELMISARTAN, HYDROCHLOROTHIAZIDE AND CHLORTHALIDONE: APPLICATION TO COMMERCIALLY AVAILABLE DRUG PRODUCTS
A simple, precise and stability-indicating HPLC method was developed and validated for the simultaneous determination of anti-hypertensive drugs Amlodipine Besylate, Valsartan, Telmisartan and diuretics Hydrochlorothiazide and Chlorthalidone. The separation was achieved on Cosmosil PAQ (150 mm × 4.6 mm) 5 μm column with gradient flow. The mobile phase at a flow rate of 1.0 mL min−1 cons...
The solubility behavior of drugs remains one of the most challenging aspects in the formulation development. Although there was a great interest in solid dispersion systems during the past four decades to increase solubility by improving dissolution rate and bioavailability of poorly soluble drugs; there commercial use has been very limited, primarily because of manufacturing difficulties and vari...
The present study was aimed to evaluate the antioxidant activity of A.sessilis plant extracts in different solvents. The antioxidant activity was studied by phosphomolybdate method and DPPH method. In phosphomolybdate method the highest activity was shown by methanolic extract (12.044 mM of ascorbic acid eqvt/gm of sample). The highest radical scavenging activity by DPPH method was found in methan...
PHYTOCHEMICAL COMPOSITION AND IN VITRO ANTIMICROBIAL ACTIVITY OF BAUHINIA RACEMOSA LAMK (CAESALPINIACEAE)
The aim of this study was to evaluate antimicrobial activity of the leaves of the Bauhinia racemosa L. In the current study, the aqueous and methanol extract of leaves of B. racemosa L. was tested against standard bacterial and fungal cultures. In vitro antimicrobial test was performed by agar well diffusion method on Mueller hinton agar and Sabouraud dextrose agar for bacterial and fungal culture...
Pyrimidine nucleus is one of the most important heterocycles exhibiting remarkable pharmacological activities. The present review provides a broad view of the biological and medicinal activity possessed by compounds having pyrimidine nucleus....
