A simple, rapid, accurate, precise, and reproducible stability indicating RP-HPLC method for the estimation of Inotuzumab Ozogamicin in bulk and injection dosage form was developed and validated as per ICH guidelines. The separation was done using BDS C18 150 × 4.6 mm, 5 µ column. The mobile phase (Water and Acetonitrile 55:45% v/v) was pumped at 1.0 ml/min, and effluent was detected at 240 nm using a PDA detector. The retention time was 2.93 ± 0.1 min, and the method produced a linear response in the concentration range of 4.5-27 µg/ml (r2– 0.9995). In recovery studies, %RSD from reproducibility was found to be below 2%. LOD and LOQ were 0.1 µg/ml and 0.34 µg/ml, respectively. The drug was subjected to different stress conditions such as acidic, alkaline, oxidative, photothermal, and hydrolysis. The drug showed more degradation in acidic conditions, and no degradation was observed in hydrolysis and photo conditions. The developed RP-HPLC method was found to be effective, sensitive, and specific for the estimation of Inotuzumab Ozogamicin in bulk...

Verapamil hydrochloride is a water-soluble drug, so it is suitable to develop controlled porosity osmotic pump. As Verapamil HCl is a short-acting drug, so developed formulation provides the advantages of controlled release formulations. The developed formulation provides advantages of less steps of manufacturing procedure, no need for laser drilling, and economical, all of which made the procedure easily amenable to mass production using conventional tablet machines. Verapamil HCl 120 mg core formulations were prepared coated with film former (cellulose acetate): pore former (sorbitol). The effect of different formulation variables, namely, membrane weight gain, and amount of pore former in the membrane, were studied. Verapamil HCl release was inversely proportional to the membrane weight (coating thickness) but directly related to the initial amount of pore former (sorbitol) in the membrane. Drug release from the developed formulations was independent of pH but dependent on the osmotic pressure of the release medium. Verapamil HCl release from the developed formulation follows zero-order. The drug release from formulation was proved as dependent on osmotic...

A glycyrrhetinic acid isolated from herbal plant Glycyrrhiza glabra (family Fabaceae), commonly known as licorice is used to formulate microemulsion as a self-emulsifying drug delivery system for oral administration using almond oil as the oil phase. Pseudoternary phase diagrams were constructed to determine the microemulsion existence region using surfactant (Tween 80) and co-surfactant (propylene glycol). Different formulations in the form of microemulsions were prepared to evaluate the effect of oil content, surfactant/co-surfactant concentration on in-vitro diffusion rates. In-vitro drug diffusion of glycyrrhetinic acid from the microemulsions was evaluated using the dialysis membrane. The amount of glycyrrhetinic acid permeated was analyzed by using the UV method. The permeability of the glycyrrhetinic acid incorporated into the microemulsion systems was considerably increased than that of the plain drug. These results indicate that the microemulsion system studied is a promising tool for increasing the solubility and oral absorption of glycyrrhetinic...

From bench to bedside, clinical research had always played as a convenient tool in the field of cancer biology to inquire about the effectiveness of different anticancer drugs on different human-derived cancer cell lines. According to the American Cancer Society, nearly 4000 new cases and 1600 deaths predicted in 2019 in the United States. Besides, to these alarming statistics, rising cost and health-related complications associated with treatments had made the research of cell lines on the anticancer drug more relevant. This article providing a comprehensive review of cancer, advanced development of the anticancer drugs, and a brief inference on progression-free survival rate (PFS) of the following anticancer and engineered monoclonal antibody drugs are...

The present research work was envisaged to develop immediate release film-coated tablets of a fixed-dose combination of Atorvastatin calcium and Amlodipine besylate used to treat the hyperlipidemia, angina pectoris, atherosclerosis, hypertension and symptoms of cardiac risk. Additionally, fixed-dose combination therapy of both drugs tends to provide a synergetic effect and reduce the pill burden. Immediate-release tablets are mostly recommended for fast upgrading drug delivery systems, and thus, an effort was made to improve the onset of action of the drug. The concept of formulating immediate-release tablets using superdisintegrants like CCS offers a suitable and practical approach to faster disintegration and dissolution characteristics. In the current investigation two methods were adopted namely direct compression and wet granulation for formulation development. Based on the drug content and dissolution results, the direct compression method was used for further study. The prepared dosage forms were also subjected to pre and post compression evaluations. The results of in-vitro drug release suggested that CF6 was the ideal formulation among all the other formulations. In-vitro drug...
