Abstract:
In this general overview, we discussed about dentifrices, types of dentifrices, formulation, evaluation and its recent trends. There have been many dentifrices produced over the years, many focusing on marketing strategies to sell products, such as offering whitening capabilities. The most essential dentifrice recommended by dentists is toothpaste which is used in conjunction with a toothbrush to help remove food debris and dental plaque.

ABSTRACT:
The antibacterial activity of essential oils and their derivatives has been recognized for a long time. In the present study, the antibacterial properties of the essential oils obtained from the seeds of Seseli indicum, of Apiaceae family a wild weed found in the flood prone area of river Tapti, Gorakhpur (India). The essential oil obtained from seed was 3.4%. Essential oils were investigated for activity against Escherichia coli, Staphylococcus aureus and Bacillus subtilis using a punched-hole method. Essential oils inhibited all bacteria at both, low and high concentration. The results of this study confirmed the possibility of using Seseli indicum essential oils in broad spectrum antibacterial activities.

1.Abstract
Aceclofenac is a drug with narrow therapeutic index and short biological half-life, so can achieve steady state concentration rapidly. This study was aimed at developing and optimizing niosomal formulation of aceclofenac in order to improve its bioavailability as compare to liposomes.This niosome is prepared by modified ether injection technique. In this span 60 & span 20 is used as non ionic surfactants. Different 6 formulation are prepared, In this NFS-1 to 3 formulation are prepared using the span 60 & NFS-4 to 6 are prepared using span 20 along with different proportion of cholesterols. Because of the presence of nonionic surfactant with the lipid, there is better targeting of drugs to tumor, liver and brain. In evaluation study, the effect of the varying composition of non ionic surfactant and cholesterol on the properties such as drug entrapment efficiency, drug content, particle size & shape and drug release were studied. Moreover, the release of the drug was also modified and extended over a period of 72 h in all formulations. NSF-3 emerged as the most satisfactory formulation. Further, release of the drug from the most satisfactory formulation NSF-6 was evaluated through dialysis membrane to get the idea of drug release. The mechanism of dug release was governed by K- Peppas model. In all the niosomes prepared with spans, as the concentration of surfactant increased drug entrapment efficiency increased. Among the spans, span 60 having high phase transition temperature (gel to liquid transformation) and having critical packing parameter (CPP) ranging from 0.5 to 1 entrap drug molecule without any cholesterol. The only drawback of span 60 vesicles was rapid leakage of drug from the vesicle because of high phase transition temperature. In all the cases the best fit model was found to be Peppas with ‘n’ value between 0.65 to 0.73 suggesting the non fickian (anomalous) release mechanism for the drug i.e., erosion followed by diffusion controlled. Formulation NSF-6 showed high entrapment efficiency (96.07%±0.35), particle size (4.22±0.47μm) and drug release (87.21%) over 72 h. Hence it was considered to be good niosomal formulation with greater bioavailability.

ABSTRACT
The present study is formulating Rabeprazole modified release beads (Immediate and Time, Pulsatile Release) and to target the release of the drug in intestine and to avoid stability related problems. Preparation of immediate release (IR) Rabeprazole beads has done by drug layering process and barrier coated beads by providing an enteric coating membrane on IR beads. Timed release beads has done by providing a Film coating for IR and lag time coating for TPR (Timed, Pulsatile Release)  on enteric coated beads. Encapsulation Process and evaluation of enteric coated IR and TPR beads has done by physical evaluation and chemical evaluation. Stability studies have done for best quality Rabeprazole IR and TPR enteric coated beads formulations. Based on the results Formulation 3 and Formulation 9 were selected as the best formulation developed for Rabeprazole Dual Drug Release Capsules.

ABSTRACT:
The demand for mouth dissolving tablets has been growing during the last decade especially for elderly and children who have swallowing difficulties. Chlorpheniramine maleate is a non-steroidal anti-inflammatory drug (NSAID) histamine H1 antagonist with antihistamine drug it is commonly used  in allergic reactions, hay fever, rhinitis, urticaria, and asthma. The main criteria for mouth dissolving tablets are to disintegrate or dissolve rapidly in oral cavity with saliva in 15sec to 60sec with need of water. The disintegrants used should fulfill the criteria by disintegrating the tablets in specified time limit.in the present investigation variety of super disintegrants Crospovidone, sodium starch glycolate,kyron t-314 , were selected and tablets were prepared by direct compression method in different concentration like 3%,6% and 8%. The prepared tablets were evaluated for weight variation, hardness, friability, in vitro disintegration time, wetting time, in vitro dissolution study, etc.formulation f-9 shows the lowest disintegration time (29sec) and wetting time (37sec). In vitro dissolutionstudies revealed that formulation F-9 containning 9% t-314  showed 98% drug release at the end of 10 min.

ABSTRACT:-
In this review article, we discussed about Bioavailability and bioequilance study, bioavailability means rate and extent to which active ingredients absorbed from a drug product and become available at site of action. This article provides the information about important aspect involved in bioequivalence and regulatory requirement for bioequivalence study. The rate or rapidity at which drug is absorbed is important consideration in treatment of acute conditions such as asthma attack in pain. Extent of absorption is of special significance in treatment of chronic conditions like hypertension, epilepsy. In this review we discussed all the factors affecting bioavailability from its dosage form, objective/purpose of bioavailability study, design and evaluation of bioequilance study, methods of assessing of bioavailability and bioequilance etc.
