A simple, precise, accurate UV-spectroscopic method was developed and validated for the determination of Mycophenolate Mofetil in bulk and dosage form using solvents like methanol for dissolving the drug and acetate buffer of pH-3.5 for dilutions. At the λmax of 250nm, it was proved linear in the range 10- 50 μg/ml, and exhibit good correlation coefficient (R2 =0.995) and excellent mean recovery (99.990-100.014). The developed method was validated for accuracy, precision, robustness, ruggedness according to ICH guidelines. All these parameters showed adaptability of the method for the quality control analysis of Mycophenolate Mofetil in bulk and in marketed formulation.Keywords

The objective of the present study is to develop Aceclofenac control release matrix tablet formulations by wet granulation method employing starch citrate, a new modified starch. Starch acetate prepared by reacting potato starch with acetic anhydride in the presence of sodium hydroxide at elevated temperatures was insoluble in water and has poor swelling and gelling property when heated in water. The degree of substitution (DS) of starch acetate was found to be 1.60 and high DS develop hydrophobicity are insoluble acetone and chloroform. In the micromeritic evaluation, the angle of repose and compressibility index values revealed the excellent flow characteristic of starch acetate prepared. All the physical properties studied indicated that starch acetate is a promising pharmaceutical excipient in tablets. Aceclofenac, a widely prescribed anti inflammatory analgesic drug belongs to BCS class II and exhibit variable oral bioavailability due to its poor solubility and dissolution rate. Matrix tablets of Aceclofenac (100 mg) prepared employing starch acetate as matrix former in different proportions gave slow and controlled release more than 12 hr. Aceclofenac release was diffusion controlled and dependent on percentage of starch acetate. As the polymer concentration was increased, release rate was decreased. Good linear relationship was observed between percent polymer and release rate (K0). Thus drug release from the matrix tablets could be controlled by varying the proportion of drug: polymer in the matrix.Keywords

Solubility is one of the key parameters to attain desired concentration of drug in systemic circulation to show pharmacological response. Various methods are engaged to augment the aqueous solubility of poorly water-soluble drugs and hydrotropic solubilisation is one of them. Hydrotropy is defined as a solubilization process whereby addition of a large amount of second solutes results in an increase in the aqueous solubility of another solute and chemicals which are used in the hydrotropy are called hydrotropes like sodium benzoate, sodium citrate, urea, niacinamide etc. Based on advantages like the high selectivity, independent of pH and cheap, easy availability makes this technique more prevailing than other solubilisation methods. Mixed hydrotropy is a solubilisation technique to augment the water solubility of poorly water soluble drugs by the way of different ratio of blends of hydrotropic agents which gives synergistic augmentation effect. The purpose of this review article is to illustrate the need for solubility, hydrotropic solubilisation, mechanism of action of hydrotrope, classification of hydrotropes, advantages and mixed hydrotropic technique of solubilisation for improving the solubility which in turn helps to attain absorption and improved bioavailability.Keywords

Nowadays about 74% of drugs are taken orally and are found not to be as effective as required. To improve such characters transdermal drug delivery system was emerged. Drug delivery through the skin to attain a systemic effect of a drug is commonly known as transdermal drug delivery and differs from traditional topical drug delivery. Transdermal drug delivery systems (TDDS) are dosage forms involves drug transport to viable epidermal and or dermal tissues of the skin for local therapeutic effect while a very major fraction of drug is transported into the systemic blood circulation. The adhesive of the transdermal drug delivery system is critical to the safety, efficacy and quality of the product. Topical administration of therapeutic agents offers many advantages over conventional oral and invasive methods of drug delivery. Several important advantages of transdermal drug delivery are limitation of hepatic first pass metabolism, enhancement of therapeutic efficiency and maintenance of steady plasma level of the drug. This review article provides an overview of advantages and disadvantages, factors affecting transdermal drug delivery, components and types of transdermal drug delivery, methods of preparation and methods of evaluation.Keywords

In the pharmaceutical Industry oral route is considered as the safest and convenient route. Fast dissolving tablets (FDTs) are solid dosage forms containing drugs that disintegrate in the oral cavity within less than 1 minute leaving an easy to swallow residue. These dosage forms include superdisintegrants which impart quick disintegration with existence of saliva and can be swallowed without difficulty. Fast dissolving tablets are the very good preference for the paediatric as well as geriatric patients. To improve the bioavailability of many drugs, fast dissolving drug delivery systems are used widely. Sophisticated technologies used for manufacturing fast dissolving tablets are by direct compression method, freeze drying method, sublimation method, mass extrusion and cotton candy process. Taste is the vital factor since these tablets disintegrate directly in the mouth. FDTs are evaluated by various parameters such as hardness test, friability test, water absorption ratio, wetting time, disintegration test and dissolution test. These tablets are also well-known as mouth dissolving tablets and orodispersible tablets. This review article will emphasize on ideal properties, challenges, advantages, disadvantages, conventional techniques, patented technologies and evaluation of orodispersible tablets.Keywords

Emulgel is one of the promising topical drug delivery system for the delivery of hydrophobic drugs which overcome a variety of disadvantages of ointments and creams like greasiness as well as phase inversion. The aim of present work was to develop and evaluate Oxiconazole emulgel. Oxiconazole emulgel was prepared by using polymers like Carbopol 934 and HPMC K4M at different concentrations. Oxiconazole is a broad spectrum anti - fungal agent used in treat of various skin infections such as athlete’s foot, jock itch and ring worm. The prepared emulgels were evaluated in terms of physical appearance, measurement of pH, viscosity, spreadability, drug content and in vitro diffusion studies and skin irritation study. Formulation F1 containing carbapol 934 is considered as optimized formulation because it showed highest drug release i.e., 58.57% in 8 hrs.Keywords

Nasal drug delivery has got a great deal of attention as a convenient, reliable and potential method for the systemic administration of drugs. It is specially for those molecules which are ineffective orally and only effective if given by injection. The nasal route of drug delivery has advantages over the other alternative systems of non-invasive drug administration. Nasal route is advantageous for the drugs which are unstable on oral administration as they are much degraded in GIT or else metabolized by first pass effect in liver. Nasal route is alternative to parenteral therapy and as well helpful for long term therapy. Nasal mucosa is greatly vascularised as well as mainly permeable giving fast absorption and onset of action. Nasal route is non invasive, extensively used for the local treatment might also be used for systemic therapy as drug directly goes in systemic circulation. Nasal route gives excellent absorption of small molecules, than that of large molecules can be augmented by absorption promoters. The present review presents information pertaining to nasal drug delivery system such as advantages, limitations, anatomy of nose, mechanism of drug absorption, barriers to drug absorption, factors influencing nasal drug absorption, strategies to improve nasal absorption, excipients used in nasal formulations, nasal formulations and their evaluation.
