Numerous pharmacological compounds now on the market are ineffective in treating brain disorders ,they are not getting to the brain with the concentration required to have a pharmacological effect. Since there are many barrier as blood brain barrier (BBB), P-glycoprotein (an active efflux transporter), and specific enzymatic activity are some of the mechanisms that protect the brain from harmful circumstances. These systems, in particular BBB hinder therapeutic interventions of many medications . Thus, the majority of the medicine cannot give the desired effect because they cannot penetrate the brain, so they are useless in the treatment of brain illnesses . As a result, numerous Therefore, strategies that could enhance drug delivery to

         Niosomes are bilayer vesicles formed by the self-assembly of non-ionic surfactants, they are receiving increasing attention as a potential oral drug delivery system specifically for poor soluble drugs to enhance its dissolution and ultimately its absorption and oral bioavailability. Axitinib is a tyrosine kinase inhibitor works by blocking the vascular endothelial growth factor receptors (VEGFR), decreasing the development of neovascularization which supress the tumour growth. It is classified as class 11 drug which has low bioavailability due to its poor solubility and absorption.  In this study, axitinib (AXT) capsules based niosomes formulated by thin film hydratio

Disulfiram (DSF) is a thiocarbamate derivative that has been used for the treatment of alcoholism. Researchers recently found out that DSF, a medicine authorized by the FDA to prevent alcohol consumption, has been investigated for its potential in cancer treatment. DSF, when taken by mouth, undergoes extensive metabolism in the liver, making it unsuitable for cancer treatment via oral administration. Furthermore, DSF has demonstrated the ability to enhance the cytotoxic impact of anticancer medications while preserving healthy cells. To solve the problem of instability and insufficient therapeutic efficacy, invasomal vesicles developed with better entrapment efficiency and size to serve as a carrier for the transdermal delivery of disulf

Hepatic fibrosis is a pathophysiological outcome of sustained wound healing response to chronic liver injury charecterized by excessive accumulation of extracellular matrix proteins. Progressive liver fibrosis can be caused by chronic infection of hepatitis B or C, alcohol abuse, non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, and other relatively conditions. Liver fibrosis, the subsequent cirrhosis represent a serious medical burden; yet, there is still a lack of approved methods or drugs t

Nanomicelles, a nanocarrier drug system, recently applied in medical research as a technique to deliver therapies to the targeted site. Normal nanomicelles building units are amphiphilic molecules (surfactants or polymers) containing hydrophobic tails and hydrophilic heads that self-assembled into the hydrophobic core-hydrophilic shell-like structure that dispersed into the aqueous media upon hydration. Polymeric nanomicelles had a lower critical micelle concentration by thousands of folds than surfactants of low molecular weight, resulting in a higher stability and circulation time after administration. Mixed nanomicelles have an extra advantage by improving the stability and encapsulation e

Antibody-drug conjugates (ADCs), a powerful type of pharmaceutical medications that combine immunotherapy and chemotherapy. Pemetrexed is a multitarget antifolate agent that inhibit essential enzymes involve in purine and pyrimidine synthesis, therefore serious toxicities of pemetrexed are due to lack of selectivity despite its broad antitumor activity in a wide variety of solid tumors. The aim of the study was to formulate and evaluate our prepared Atezolizumab (AtZ)-pemetrexed (Pem) conjugates as an intravenous (I.V) injectable dosage form. The characterization of the I.V formulation involved drug content, particle size, pyrogen test, sterility test, toxicity test, and stability test. The work revealed that our previously prepared

Dermatophytosis is the most common contagious fungal disease. Iraq, like the other many countries around the world, is facing an emergence of chronic, resistant and relapsing tinea infections. This study compared the efficacy, safety and the relapse rate of a combination therapeutic regimen of itraconazole and terbinafine vs. itraconazole alone in the treatment of chronic tinea infections. The research was conducted at the dermatology and venereology outpatient’s unit, Ramadi Teaching Hospital, Iraq, during the period from May 2022 to May 2023. Patients were divided equally into two groups. Group I received combination of itraconazole and terbinafine while group II was on itraconazole alone for eight weeks for each group. For assessmen

One of the innovative approaches to delivering drugs via topical route is nanoemulation (NE), which is easy to manufacture, stable over the long term, and has a potent solubilization property. Pimecrolimus is a low water soluble drug used to treat psoriasis, eczema, atopic dermatitis and vitiligo. This work describes the high-energy ultrasonication technique used to prepare pimecrolimus nanoemulsion. A pseudo-ternary phase diagram was created in order to determine the ideal ratios of oil-surfactant/co-surfactant mixture for the creation of nanoemulsions. Based on pimecrolimus's solubility in various oils, surfactants, and co-surfactants, Tween 80 was chosen as a surfactant, ethanol as a co-surfactant, and benzyl alcohol as an oil phase .

The term "inflammatory bowel disease" refers to a group of gastrointestinal tract inflammatory disorders that are considered idiopathic, chronic, and relapsing. The two primary disorders that comprise inflammatory bowel disease are Crohn's disease and ulcerative colitis. Infliximab, a chimeric monoclonal antibody, is a medication used to treat a number of autoimmune diseases such ulcerative colitis, Crohn’s disease, rheumatoid arthritis, and psoriasis. Therapeutic drug monitoring is a tool used in therapeutic decision-making that allows dosage modifications to be made in accordance with clinical and laboratory measures, usually blood concentrations of the drug, in order to achieve the drug exposure linked to the best res

The transdermal route of drug delivery has received significant attention in pharmaceutical research due to its ability to overcome many challenges associated with oral medication administration, including the ability to bypass first-pass metabolism, ensuring a more predictable and prolonged period of action, as well as minimizing the occurrence of adverse reactions. Transferosomes are a type of ultra-deformable lipid-based vesicles, that have the potential to offer several benefits compared to the traditional lipid-based vesicles such as liposome. The major goal of this research was to prepare (for the first time) dapagliflozin-loaded transferosomes for the purpose of minimizing the potential risk of hyperglycemia associated with oral a

          Chronic stable angina pectoris (CSAP) is a prevalent heart disease which can be defined as a symptom or a clinical syndrome of stable coronary artery disease (CAD). CAD is usually caused by the presence of atherosclerotic plaques or blood clot within coronary arteries that may lead to ischemia. miRNA 133a is mainly expressed in the muscle and it has a role in apoptosis, angiogenesis, hypertrophy, atherosclerosis and ischemia. MR-proADM is of endothelial origin and produced by different sites in the body mainly by the heart, kidneys, lungs and adrenal medulla. MR-proADM plasma level is thought to be predictive of CAD. The aim of the current study was to detect the serum levels of micr

Abstract

A sensitive, precise and reliable indirect spectrophotometric method for the determination of chlordiazepoxide (CDE) in pure and pharmaceutical dosage forms is described. The method is based on oxidative coupling reaction between amino group resulting from acidic decomposition of CDE with phenothiazine in the presence of sodium periodate to produce an intense green soluble dye that is stable and shows a maximum absorption at 602 nm. The calibration plot indicates that Beer’s law is obeyed over the concentration range of 0.1?50 µg/mL, with a molar absorptivity of 1×10⁴ L/mol cm and correlation coefficient of 0.9994.All the conditions that affecting on the stability and sensitivity of the fo

Adiponectin is one of the most important hormones secreted by adipose tissue and plays a major role in the development of obesity. A variant-specific ADIPOQ single nucleotide polymorphism (SNP rs-266729) with a C to G missense mutation can be strongly associated with obesity. Therefore, this study aims to evaluate the association of single nucleotide polymorphisms (SNP rs-266729) of the ADIPOQ gene with obesity and some biochemical markers in these patients. The case-control study included 186 participants (106 patients and 80 healthy control). DNA was extracted from whole blood and then the Restriction Fragment Length Polymorphism Polymerase Chain Reaction (RFLP-PCR) technique was used to limit the genotype of the ADIPOQ gene (rs266729)
