Introduction
Recent trends in Pharmaceutical formulation development technology have presented viable dosage alternatives for patients who may have difficulty swallowing tablets or liquids. Traditional tablets and capsules administered with an 8-oz. (One glass) of water may be inconvenient or impractical for some patients. However, some patients, particularly pediatric and geriatric patients, have difficulty swallowing or chewing solid dosage forms. Many pediatric and geriatric patients are unwilling to take these solid preparations due to fear of choking. For example, a very elderly patient may not be able to swallow a daily dose of antidepressant in the form of a Caplet shaped Tablet. An eight-year-old with allergies could use a more convenient dosage form than antihistamine syrup. A schizophrenic patient in the institutional setting can hide a conventional tablet under his or her tongue to avoid their daily dose of an atypical antipsychotic. A middle-aged woman undergoing radiation therapy for breast cancer may be too nauseous to swallow her H2-blocker. Fast-dissolving tablets (FDTs) / Orally disintegrating tablets (ODTs) are a perfect fit for all of these patients. Fast-dissolving drug delivery systems have rapidly gained acceptance as an important new way of administering drugs. There are multiple fast-dissolving OTC and Rx products on the market worldwide, most of which have been launched in the past 3 to 4 years. There have also been significant increases in the number of new chemical entities under development using a fast-dissolving drug delivery technology.

Abstract
Transdermal drug delivery system (TDDS) has emerged as a potential novel drug delivery system in the last 30 years to improve the therapeutic efficacy and safety, maintain steady state plasma level of drugs and overcome significant drawbacks of the conventional oral dosage forms and parenteral preparations. TDDS is ideally suited for diseases that demand chronic treatment with frequent dosing. This review deals with a brief insight on the formulation aspects, the physical and chemical enhancers being explored to enhance the transdermal delivery of drugs across the stratum corneum, the evaluation parameters (physicochemical, in vitro, in vivo studies) and therapeutic applications of TDDS.

Abstract:
Ayurvedic Pharmaceutical Sciences has been recently reinforced in Indian pharmacy institute due to global acceptance of Ayurveda. Some pharmacy institute have continued curriculum related to Ayurvedic Pharmaceutical Sciences as integral part of pharmacognosy or medicinal chemistry. Some pharmacy schools pioneered courses related exclusively to Ayurvedic Pharmaceutical Sciences. The courses available range from diploma to master’s level however there is little information has accumulated for doctorate and postdoctrate level studies in Ayurvedic Pharmaceutical Sciences.

Abstract
Pre-clinical phase is a laboratory test of a new drug on animal subjects, conducted together evidence justifying a clinical trial. For those drugs which are in clinical phase, method development requires various pre-clinical bioanalytical support parameters. Bioanalytical support plays a pivotal role in answering a series of questions concerning the toxicity, pharmacokinetic parameters, safety assessment, formulation optimization .Once method development process was initiated one should know the different techniques of sampling, handling, sample preparation methods that are suitable and problems in it. After sample preparation, suitable analytical techniques have to be selected for method development.  The developed method now have to be validated, for this, Initially “Analytical Instrument Qualification” has to be performed which includes four main phases- Design qualification, Installation qualification, Operational qualification and Performance qualification. Method is said to be validated when all considered validation parameters like linearity, specificity, selectivity etc are within the limits. Thus the method is developed and validated for a drug in preclinical phase using analytical technique of suitable sensitivity and selectivity.

Abstract
A simple, accurate, cost effective and reproducible spectrophotometric method has been developed for the estimation of Sitagliptine in bulk and pharmaceutical dosage form. Visible spectrophotometric method, which is based on measurement of absorption at maximum wavelength 540 nm. The accuracy of the methods was assessed by recovery studies and was found to be ranging from 99.5-101.5 .The developed method was validated with respect to linearity, accuracy (recovery), precision and specificity. Beers law was obeyed in the concentration range of 25-125 µg/ml having line equation y = 0.026x + 0.016 with correlation coefficient of 0.999. Results of the analysis were validated statistically and by recovery study.

Abstract
This article provides a basic view of what defines biological medicinal Products, often called biologicals, and how they differ from chemical products. In entering into this thought process, let us remember that proteins range in size from small amino acid chains up to macromolecules of hundreds of kilodaltons in size. In addition, in order to appreciate the science behind the regulations, an understanding of organic chemistry is necessary, and preferably knowledge of molecular cell biology and how proteins are created in cells via the DNA expression mechanisms. Although the details are inevitably complex and specialist as a result, we will look at some basic concepts pertinent to biologicals so that a regulatory generalist can be effective in dealing with such products.

Abstract
Pulsatile Drug Delivery Systems are gaining a lot of interest as they deliver the drug at the right place at the right time and in the right amount, thus providing spatial and temporal delivery and increasing patient compliance. These systems are designed according to the circadian rhythm of the body. The principle rationale for the use of pulsatile release of the drugs is where a constant drug release is not desired. A pulse has to be designed in such a way that a complete and rapid drug release is achieved after the lag time. Various systems like capsular systems, osmotic systems, single- and multiple-unit systems based on the use of soluble or erodible polymer coating and use of rupturable membranes have been dealt with in the article. It summarizes the latest technological developments, formulation parameters, and release profiles of these systems. These systems are beneficial for the drugs having chronopharmacological behavior where night time dosing is required, such as anti-arhythmic and anti-asthmatic. Current review article discussed the reasons for development of pulsatile drug delivery system, types of the disease in which pulsatile release is required, classification, advantages, limitation, and future aspects of pulsatile drug delivery system.

Abstract
Animal testing had been in practice from the last many decades. Animal testing and experimentation leads to killing and cruelty of hundreds of thousands of animlas each year. Misconception is so much about the general public that the use of animals is considered mandatory for meeting the learning objectives. The existence of methods like In vitro pyrogen test, embryonic stem cell test, carcinogenicity test etc. has paved the good pathway for the usage of alternatives to animal experimentation. Alternatives to animal experiments can only be put into practice by the general awareness of the public about the animal welfare, the tediousness of the animal methods, and the expensive and time consuming nature of these methods. In this review a various alternative testing methods are discussed so that pavement should be directed into a meaningful research, healing and protection and is mandatory for restoring faith and respect in medical profession. This review will provide an insight on the various alternatives to animal experimentation so that a path can be lighted which would be terror free and without dragging the animal to a life of horror and unbearable pain.

EDIBLE VACCINE - A GREAT BOON IN MEDICINAL SCIENCE

Abstract
Biotechnologists in recent years have come up with a new concept.This new concept is about edible vaccine. The difference here lies, that crops like “golden rice” provided extra nutrition that naturally didn’t occur in it. But edible vaccines are GM crops that would provide extra added “immunity” from certain diseases.
Edible vaccines are composed of antigenic proteins and do not contain pathogenic genes (because obviously they use attenuated strains). Thus, they have no way of establishing infection and safety is assured.Oral administration is possible , production is highly efficient and can be easily scaled up.For example, hepatitis-B antigen required to vaccinate whole of China annually, could be grown on a 40-acre plot and all babies in the world each year on just 200 acres of land,Cheaper (single dose of hepatitis-B vaccine would cost approximately 23 paise), grown locally using standard methods and do not require immense capital investment of pharmaceutical manufacturing facilities, exhibit good genetic stability. Do not require special storage condition. Since syringes and needles are not used chances of infection are also less. Fear of contamination with animal viruses - like the mad cow disease, which is a threat in vaccines manufactured from cultured mammalian cells - is eliminated, because plant viruses do not infect humans.
