Abstract
Tablet is the most preferred oral dosage form, due to many advantages it offers to formulators as well as physicians and patients. However, the process of manufacturing tablets is complex. Hence, careful consideration has to be given to select right process, and right excipients to ultimately give a robust, high productivity and regulatory compliant product of good quality.

ABSTRACT
Postoperative adhesions are a significant health problem with major implications on quality of life, health care and expenses on treatment. The purpose of this review was to investigate the incidence of post operative adhesions and the treatment measures such as efficacy of preventative techniques and adhesion barriers. The National Library of Medicine, Medline and A-Z databases were used to identify articles related to postoperative adhesions. Ileal pouch–anal anastomosis, open colectomy, and open gynecologic procedures are associated with the highest risk of adhesive small-bowel obstruction (class I evidence). Based on expert opinion (class III evidence) intraoperative preventative principles, such as meticulous haemostasis, avoiding excessive tissue dissection and ischemia, and reducing remaining surgical material such as powdered gloves have been published. Laparoscopic techniques, result in fewer adhesions than laparotomy techniques (class I evidence). Available bioabsorbable barriers, such as hyaluronic acid/carboxymethylcellulose, have been shown to reduce adhesions (class I evidence). Postoperative adhesions are a significant health problem after the surgery. General intraoperative preventative techniques, laparoscopic techniques, and the use of bioabsorbable mechanical barriers in the appropriate cases reduce the incidence and severity of peritoneal adhesions and post operative adhesions.

Abstract:
Nanoparticles are the preparations having size in nanometers. Particulate systems like nanoparticles have been used as a physical approach to alter and improve the pharmacokinetic and pharmacodynamic properties of various types of drug molecules. They have been used in vivo to protect the drug entity in the systemic circulation, restrict access of the drug to the chosen sites and to deliver the drug at a controlled and sustained rate to the site of action. Various polymers have been used in the formulation of nanoparticles for drug delivery research to increase therapeutic benefit, while minimizing side effects. Here, we review various aspects of nanoparticle formulation, characterization, effect of their characteristics, drug loading, in vitro release profile and their applications in delivery of drug molecules and therapeutic genes.

ABSTRACT
As a very few drugs are coming out of research and development and already existing drugs are suffering the problem of resistance due to their irrational use. Hence, change in the operation is a suitable and optimized way to make the some drug more effective by slight alternation in the drug delivery. Presently pharmaceutical industries are focusing on development of sustained release formulations due to its inherent boons. Sustained release dosage forms are designed to release a drug at a predetermined rate by maintaining a constant drug level for a specific period of time with minimum side effects. The basic rationale of sustained release drug delivery system optimizes the biopharmaceutical, pharmacokinetic and pharmacodynamics properties of a drug in such a way that its utility is maximized, side-effects are reduced and cure of the disease is achieved. There are several advantages of sustained release drug delivery over conventional dosage forms like improved patient compliance due to less frequent drug administration, reduction of fluctuation in steady-state drug levels, maximum utilization of the drug, increased safety margin of potent drug, reduction in healthcare costs through improved therapy and shorter treatment period. The basic goal of sustained release is provide promising way to decrease the side effect of drug by preventing the fluctuation of the therapeutic concentration of the drug in the body and increase patient compliance by reducing frequency of dose. This article contains the basic information regarding sustained-release formulation and also the different types of the same.

ABSTRACT
Acyclovir is an Anti-viral drug, widely used in the treatment of Ocular herpes simplex. Ophthalmic insert of acyclovir formulated using Methyl cellulose (MC A4CP), polyvinylpyrrolidone (PVP K30) and polyvinyl alcohol as polymers and glycerin use as plasticizer by solvent casting method with aim of increasing the contact time, achieving sustained release drug. The prepared ophthalmic insert were evaluated for uniformity of thickness, weight uniformity, drug content, % moisture absorption, % moisture loss, folding endurance and surface pH. In vitro drug release of formulated batches was performed using Modified Franz Diffusion cell. A 3² full factorial design was applied to systematically optimize the ocular insert. FTIR spectroscopy was performed to study the drug interaction effect in formulation using KBr disc method. On the basis of all physicochemical parameters and in vitro drug release studies, and overall Desirability, the formulation (F8) was found to vary significantly depending on the type of polymers used and their combinations and it was selected for sterility, stability, ocular irritancy study. The result of invitro diffusion study of formulation exhibited non-fickian in nature. From stability studies inserts were remained stable both physically and chemically. The formulation was found to be practically nonirritant in ocular irritation studies using hen's egg chorioallantoic membrane.

Abstract
Irbesartan is chemically 2-butyl-3-({4-[2-(2H-1,2,3,4-tetrazol-5-yl) phenyl] phenyl} methyl) -1,3-diazaspiro [4.4] non-1-en-4-one. Irbesartan is an Angiotensin II receptor antagonist effective in the treatment of   Hypertension.  It is also effective in the treatment of High blood pressure.  It is also effective when used alone or in combination with other drugs. Objective of the present study is to develop a simple, sensitive, accurate, precise and rapid first order derivative spectrophotometric method for the estimation of irbesartan in pure form. For the estimation of irbesartan, solvent system employed was 50% v/v aqueous ethanol and wavelength of detection (λ_det) was 237 nm. The linearity was obtained in the range 8 – 18 µg/ml, with a regression coefficient, R² = 1. The LOD & LOQ were found to be 0.5 µg/ml and 1.63 µg/ml respectively. Obtained results showed that there is minimum intra day and inter day variation. The developed method was validated and recovery studies were also carried out. Sample recovery using the above method was in good agreement with their respective labeled claims, thus suggesting the validity of the method and non-interference of formulation excipients in the estimation. First order derivative spectroscopy method is simple, rapid and reproducible and further it can be used for the analysis.

Abstract
The aim of the present investigation is to know about AIDS and its treatments. Various treatments for AIDS are described here.AIDS stands for acquired immunodeficiency syndrome. Acquired immune deficiency syndrome(AIDS) is a disease of the human immune system caused by the human immunodeficiency virus (HIV). HIV is transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk. This transmission can involve anal, vaginal or oral sex, blood transfusion, contaminated hypodermic needles, exchange between mother and baby during pregnancy, childbirth, breast feeding etc. As of 2009, AVERT estimated that there are 33.3 million people worldwide living with HIV/AIDS, with 2.6 million new HIV infections per year and 1.8 million annual deaths due to AIDS. Highly active antiretroviral therapy (HAART) continues to have a favourable impact on disease progression and mortality in settings where it is available to people living with HIV.
