1. Abstract:
Pharmacokinetics is currently defined as the study of the time course of drug absorption, distribution, metabolism, and excretion. Clinical pharmacokinetics is the application of pharmacokinetic principles to the safe and effective therapeutic management of drugs in an individual patient.
Primary goals of clinical pharmacokinetics include enhancing efficacy and decreasing toxicity of a patient's drug therapy. The development of strong correlations between drug concentrations and their pharmacologic responses has enabled clinicians to apply pharmacokinetic principles to actual patient situations.
A drug's effect is often related to its concentration at the site of action, so it would be useful to monitor this concentration. Receptor sites of drugs are generally inaccessible to our observations or are widely distributed in the body, and therefore direct measurement of drug concentrations at these sites is not practical. For example, the receptor sites for digoxin are believed to be within the myocardium, and we cannot directly sample drug concentration in this tissue. However, we can measure drug concentration in the blood or plasma, urine, saliva, and other easily sampled fluids.

ABSTRACT:
Thermogravimetry is a branch of physical chemistry, materials research, and thermal analysis. It is based on continuous recording of mass changes of a sample of material, as a function of a combination of temperature with time, and additionally of pressure and gas composition.

It includes different types of Thermogravimetric analysis. In this article types, Instrumentation, Procedure, Application are priscribed.

ABSTRACT
A novel stability-indicating RP-HPLC method has been develop and validated for quantitative analysis of Sitagliptin in the bulk drug and in its pharmaceutical dosage forms using Hypersil–BDS- C18 column (250x4.6mmi.d, 5µ particle size) with 10mM Phosphate buffer (PH-3.5): ACN 60:40%v/v as isocratic mobile phase enabled separation of the drug from its degradation products. UV detection was performed at 260 nm. The method was validated for linearity, accuracy (recovery), precision, sensitivity, ruggedness and robustness. The linearity of the method was excellent over the range 10–60μg/ml (correlation coefficient 0.999). The limits of detection and quantification were 0.21 and 0.640μg/ml, respectively. Recovery of Sitagliptinfrom the pharmaceutical dosage form ranged from 99.99 to 100.05%.

Sitagliptin was subjected to stress conditions (Hydrolysis (acid, base), oxidation,thermal and photo degradation) and the stressed samples were analysed by use of the method. Degradation was observed in acid, base, and 30% H2O2. The drug was stable under the other stress conditions investigated. The degradation products were well resolved from main peak. The forced degradation studies prove the stability indicating power of the method.

ABSTRACT:
Medicinal chemistry and pharmaceutical chemistry are disciplines at the intersection of chemistry, especially synthetic organic chemistry, and pharmacology and various other biological specialties, where they are involved with design, chemical synthesis and development for market of pharmaceutical agents, or bio-active molecules (drugs).Very important part of above is the heterocyclic-chemistry. Now a days so many investigation are carried out for developing new chemical entities having suitability for human life. A lot of research work is going on presently for development of new heterocyclic derivatives.The present review article is concern with the three, five-membered heterocyclic compound pyrrole, furan & thiophene  derivatives that show diverse pharmacological activities.

ABSTRACT:
Stability is an essential quality attribute for drug products. If there is any functionally relevant quality attribute of a drug product that changes with time, this evaluation checked by pharmaceutical scientist and regulators who quantify drug product stability and shelf life. The rate at which drug products degrade varies dramatically. E.g. radiopharmaceutical products. Since the evaluation of the stability of drug is highly specialized and esoteric nature. Drug stability concerns about drug product safety, efficacy, and quality, found it to appropriate. Stability studies are done through the regulatory agencies such as FDA and HPB (health protection branch).

Abstract
The present work describes the effect of methanolic extract of Prunus amygdalus (batsch.) on pylorus ligation and Ethanol-induced gastric ulcer models in Wistar rats. The present study provides a strong evidence of antiulcer activity of Prunus amygdalus extract against gastric lesions. The antiulcer activity is recognized by a reduction in acid-secretary parameters like total and free acidity, gastric volume and ulcer score suggesting that acid inhibition accelerates ulcer healing, thereby strengthening of mucosal barrier. In this present study it shows significant protection for Hexosamine in all treated groups in comparison to negative control group. Inthe LPO results it was observed that there was significance level difference in negative control group and all other group that indicates that lipid peroxides enzyme was higher in vehicle treated group. Ulcer score was determined by the counting of spots and severity of damage in stomach part by any moiety such as ethanol. Single drug treatment (200 mg/kg and 400mg/kg of P.A.E.) was effective up to a significant level (P<0.05) in compare to negative control group.Volume of gastric juice indicate the secretions of gastric fluid and it is higher in negative control group and all drug treated group was effective in relation to negative control group in significance level (P <0.05).
