RP-HPLC METHOD FOR SIMULTATANEOUS DETERMINATION OF IRBESARTAN, LOSARTAN, HYDRO-CHLOROTHIAZIDE 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 Irbesartan, Losartan, diuretics Hydrochlorothiazide and Chlorthalidone. The separation was achieved on Hypersil BDS (Length 250 mm × Diameter 4.6 mm Particle size 5 μm) column with gradient flow. The mobile phase at a flow rate of 1.0 mL min−1 ...
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...
VALIDATED HPTLC METHOD FOR SIMULTANEOUS DETERMINATION OF LAMIVUDINE AND ABACAVIR SULPHATE IN TABLET DOSAGE FORM
A simple, precise, accurate and rapid high performance thin layer chromatographic method has been developed and validated for the simultaneous estimation of Lamivudine and Abacavir sulphate in combined dosage forms. The stationary phase was precoated silica gel 60F254. The mobile phase used was a mixture of (Acetone: chloroform: methanol 4: 4: 2 v/v/v). The detection of spot was carried out at 265...
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...
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...
DASAPUSHPAM: THE TRADITIONAL USES AND THE THERAPEUTIC POTENTIAL OF TEN SACRED PLANTS OF KERALA STATE IN INDIA
The Western Ghats of Kerala is famous for its medicinal plant wealth and the tradition of indigenous system of therapy, specifically the Ayurveda. Dasapushpam constitute a group of ten potential herbs which are culturally and medicinally significant to the people of Kerala in India. They are a group of ten herbs with which the ladies decorate their hairs and dance the Thiruvathira Kali on the day ...
In general, we know that small intestine is mostly the site for drug absorption but in some cases the drug needs to be targeted to some other sites for absorption due to various factors like any disease condition, degradation related situations, for sustained release of drugs etc. Colon targeted drug delivery is a relatively new concept for the absorption of drugs as it offers near neutral pH. Als...
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...
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...
Nanoemulsions are submicron sized emulsions that are under investigation as drug carriers for improving the delivery of therapeutic agents. These are the thermodynamically stable isotropic system in which two immiscible liquids are mixed to form a single phase by means of appropriate surfactant and cosurfactant. Nanoemulsion droplet sizes fall typically in the range of 20-200nm and shows narrow si...
