The object of the study was to formulate and evaluate Aceclofenac orodispersible tablets (ODT) by wet granulation method using different super disintegrants in different concentrations. Orodispersible tablets produce rapid dissolution of drug and absorption thereby producing rapid onset of action. Five batches (AFD1, AFD2, AFD3, AFD4, AFD5) of Aceclofenac orodispersible tablets were prepared and characterized for hardness, friability, thickness, uniformity of weight, drug content, disintegration time, In-vitro dissolution studies. Formulation (AFD5) was found to be better formulation in terms of rapid disintegration and maximum percentage of drug release compared to other...

A simple, sensitive, highly accurate UV spectrophotometric method has been developed for the determination of mesalamine in bulk and tablet dosage form. Solution of mesalamine in distilled water shows maximum absorbance at 330 nm. Beer’s law was obeyed in the concentration range of 2-16 μg/ml with the slope, intercept, correlation coefficient, detection and quantitation limits were also calculated. The proposed method has been applied successfully for the analysis of the drug in pure and in its tablets dosage forms. Result of percentage recovery and placebo interference shows that the method was not affected by the presence of common excipients. The method was validated by determining its sensitivity, accuracy and precision which proves suitability of the developed method for the routine estimation of mesalamine in bulk and solid dosage form. The method was then validated for different parameters as per the ICH (International Conference for Harmonization) guidelines. Mesalamine was subjected to stress degradation under different conditions recommended by ICH. The samples generated were used for degradation studies using the developed...

Lamivudine, a BCS Class I synthetic nucleoside analogue, has a a short biological half-life of 5–7 and is mainly absorbed in the upper gastrointestinal tract. The purpose of the study is to develop a controlled release floating tablets of lamivudine employing HPMC K4M and sodium alginate. The floating tablets of lamivudine were prepared employing HPMC K4M and sodium alginate as matrix formers and sodium bicarbonate as an effervescent agent. The tablets formulated were evaluated for tablet weight variation, drug content uniformity, hardness, friability, floating behaviour and in-vitro drug release. All the formulations fulfilled the official requirements for tablet weight variation, drug content uniformity, hardness and friability. Tablets formulated by using a combination of HPMC K4M/sodium alginate and HPMC K4M alone gave a lesser floating lag time when compared with tablet formulated with sodium alginate alone. All the tablets were found to remain buoyant in 0.1N HCl for a period >24h. The drug release from the prepared tablets was found to be diffusion controlled and followed first order kinetics. Non-Fickian...

A substantial interest in rational design of novel transition metal complexes which bind and cleaves duplex DNA has been a motivation of the present investigation. This DNA adhesion of metal complex which targets bacterial DNA and cleaves it thereby results in an effective antibacterial agent. In the present work two series of metal diketonates were prepared by using diketones like acetyl acetone and benzoyl acetone. Metals like Cu2+, Ni2+, Co2+ were used for complexation. Bacterial cultures Staphylococus aureus, Bacillus subtilis, Escherichia coli and pseudomonas aeruginosa and fungal cultures Candida albicans, Aspergillus niger were used for screening anti-bacterial and anti-fungal activities respectively. Anti-microbial screening was carried out by using Kirby-Bauer disc plate method .It was found that metal complexes of benzoyl acetone shown more anti-microbial action. The presence of aryl ring in the molecular structure seems to augment the antimicrobial activity of the compound. Further Cu (II), Ni (II), Co (II) complexes of ML2 stoichiometry were characterized by UV, IR, mass and 1H NMR...

Objective: To assess incidence, causality, severity, predictability and preventability of adverse drug reactions (ADRs) in hospitalised oncology patients. Materials and Methods: A prospective observational, non-randomized, parallel sequence study was conducted at Dr B. Borooah Cancer Institute (BBCI) after getting an approval from human ethical committee. Patients hospitalised at BBCI from Aug 2010 to June 2011 were interviewed about symptoms related to their drug therapy. Patient medical records were also reviewed for data collection. Results: Total 663 patients associated with hospitalizations were interviewed. 899 ADRs were identified in total 410 (61.84%) patients detected with ADRs. Most of all ADRs were moderate, predictable and not preventable. The most common ADRs were leucopenia, weakness, anorexia, alopecia, vomiting, diarrhoea, nausea, abdominal pain, fatigue, and anaemia in this study. Conclusions: For definite conclusion study should be repeated. Strict drug analyzing and in vivo study is also required if feasible. Key message: The process of defining and concluding about ADRs should be continuous and ongoing to keep a record of newly marketed drugs and medicinal...
