ABSTRACT
This method describes simple, sensitive, rapid, accurate, precise and economical derivative spectroscopic methodfor the simultaneous determination of tolperisone hydrochloride (TOL) and diclofenac sodium (DIC) in bulk and synthetic mixture. In this study, dual wavelength spectroscopic method was used for simultaneous determination of tolperisone hydrochloride and diclofenac sodium using the absorbance difference at two wavelengths. The absorbance differences of 257 nm and 306.20 nm were selected for the estimation of TOL and the absorbance differences of 243.40 nm and 265.40 nm were selected for estimation of DIC. The method was found to be linear (r2>0.999) in the range of 2- 18 μg/ml for tolperisone hydrochloride. The linear correlation was obtained (r2>0.997) in the range of 2- 18 μg/ml for diclofenac sodium. The limit of determination was 0.66 and 0.27 μg/ml for tolperisone hydrochloride and diclofenac sodium respectively. The limit of quantification was 2.00 and 0.83 μg/ml. The method was successfully applied for simultaneous determination of tolperisone hydrochloride and diclofenac sodium in binary mixture.

Abstract:
Oral controlled drug delivery systems represent the most popular form of controlled drug delivery systems for the obvious advantages of oral route of drug administration. However, there are certain conditions for which such a release pattern is not suitable like cardiovascular diseases, Diabetes mellitus, Asthma, Arthritis, Peptic ulcer etc. In such cases pulsatile drug delivery system is used in which release drug on programmed pattern i.e. at appropriate time & at appropriate site of action. Pulsatile Drug Delivery systems are basically time controlled drug delivery systems in which the system controls the lag time independent of environmental factors like pH, enzymes, gastro-intestinal motility, etc. The principle rationale for the use of pulsatile release is for the drugs where a constant drug release, i.e., a zero-order release is not desired. In chronopharmacotherapy drug administration is synchronized with biological rhythms to produce maximal therapeutic effect & minimum harm for the patient. Technically, pulsatile drug delivery systems administered via the oral route could be divided into two distinct types, the time controlled delivery systems and the site-specific delivery systems, thus providing special and temporal delivery. In recent pharmaceutical applications involving pulsatile delivery; multiparticulate dosage forms (e.g. pellets) are gaining much favor over single-unit dosage forms. Various pulsatile technologies have been developed on the basis of methodologies, these includes ACCU-BREAK™, AQUALON,  CODAS®, PRODAS^®, SODAS®, MINITABS^®, DIFFUCAPS®, OROS® etc. Designing of proper pulsatile drug delivery will enhance the patient compliance, optimum drug delivery to the target side & minimizing the undesired effects.

Abstract:
Herbal medicines are very popular in treatment of the asthma in the modern era because of lots of benefits of it like less cost, less side effects, easily available etc. Herbal alternatives to asthma are better way for treatment of asthma. Various herbal medicines recognize that immune system functioning can play a vital role in helping to control the symptoms of asthma and strengthen the body's defenses against environmental allergens. Herbal medicines like ephedra, ginger, chamomile, elderberry, licorice, mullein, stinging nettle etc are very beneficial in asthma. Scientists have found evidence to support herbal's wide range of medicinal actions. These actions include the lowering of cholesterol levels, relief for allergies and asthma etc. Herbs have been used by people for longer than we have been keeping written record. Originally they were found in the wild by the gatherers and used for lots of different things. I light here, the use of herbals in asthma. It aims to tap into the body’s own healing mechanism by transforming the “triggers” of such attacks as part of the remedy. Opinions of different authors are saying that herbal medication is better way for asthma treatment.

Abstract:
Interest in transdermal drug delivery systems has increased on several fronts over the past several years because of the inherent advantages over the oral delivery such as the avoidance of gastrointestinal absorption, enzymatic and pH associated deactivation. Stratum corneum forms highly lipophilic membrane and provides the greatest resistance to penetration of drugs. A number of chemical and physical permeation enhancement techniques have been investigated. Chemical enhancers represent the most widely studied approach to transdermal drug permeation enhancement but are associated with toxicity, therefore limiting their clinical application. In recent years the emergence of number of physical techniques has expanded the range of drugs that can be delivered transdermally. Promising new technologies involved in enhancing transdermal permeation are Abrasion, Electroporation, Sonophoresis/Phonophoresis, Pressure waves, Iontophoresis, Laser Radiation,Magnetophoresis, Microneedles, Needleless injection and many more. In the present reviewed tried to discuss alternate techniques of enhancing the transdermal transport.

ABSTRACT
Sustained releases tablets have been used for reduced the dosing frequency and maintain the plasma drug concentration level within narrow therapeutic range. Aspirin used as antiplatelate agent and Atorvastatin is HMG-CoA reductase inhibitor which lowers the plasma concentration of cholesterol. Here in present study sustained release tablets of Aspirin and Atorvastatin prepared by using cellulose acetate phthalate (CAP) and microcrystalline cellulose (MCC) as a polymers. The sustain release tablet of Aspirin And Atorvastatin were prepared by wet granulation method and were substituted for film coating to mask the spotting from Atorvastatin and for protection from light. From the dissolution profile of F2B2 gives controlling the release up to 12 hrs with required value i.e. - 55.85 % for Aspirin and 54.78 % for Atorvastatin in 4 hrs respectively and 100.70 % for Aspirin and 100.60 % for Atorvastatin in 12 hrs respectively. The result of stability studies of batch F2B2 indicate that it is stable at 400C / 75 % ±0.5 % relative humidity as there was no significant differences observe for dissolution and average drug content data after two months.

ABSTRACT:
Generally, controlled release dosage forms used in many applications. Superporous hydrogel is also one of them. It has lot of advantages over conventional hydrogel. Superporous hydrogel having faster swelling due to interconnected highly porous structure. Such other properties like slippery property, their mechanical strength and better foaming process are advantageous over conventional hydrogel. Its unique mechanism for achieving gastric retention, a number of hurdles have to be overcome for any approach to be clinically useful. For example, intra-gastric floating systems require the presence of gastric juice to be effective, and this may not be the case in the fasted state. Mucoadhesive systems can easily lose their mucoadhesive properties by interaction with any materials soluble in gastric juice. In this review, types of superporous hydrogel, their preparation, their characterizations and applications are discussed.
