  • Systematic Review on Interaction Studies of Synthetic Antidiabetic Drugs
           and Herbal Therapies

    • Authors: Priyanka Purohit, Brahmeshwar Mishra
      Abstract: Purpose: Complimentary and alternative therapies as well as traditional herbal home remedies are booming because they are perceived to be free of side effects and generally recognised as safe due to their natural origin. There are number of reports available on the interaction of anti diabetic drugs in vitro and in clinical trials. Diabetic patients are often treated with multiple synthetic drugs combination due to different co- morbidities and such patients should be informed regarding herb-drug interactions in clinical settings.Approach: Informations from the published research articles available from MEDLINE, Cochrane and Pub med as well as additional data sources were obtained from manual searches of recent journal articles and textbooks and were used in the preparation of this review article.Finding: Traditional home remedies and alternative therapies in treatment of Diabetes mellitus may pose concern or complications that would arise from these herbs on the pharmacodynamic and pharmacokinetic effects of synthetic drugs as they are used in combination therapy.Conclusion: Herbal remedies are complex mixtures of bioactive entities which may interact with prescription drugs through pharmacodynamic or pharmacokinetic mechanism and sometimes result in serious clinical consequences. Patients and Physician should be familiar with the potential effects of commonly used herbal medications to prevent, recognise and treat potential adverse effect associated with their uses.

  • Effect of Bile Salts on Transbuccal Permeability of Carbamazepine through
           Porcine Buccal Mucosa

    • Authors: G. Parthasarathy, K. Bhaskar Reddy, K. N. Jayaveera
      Abstract: The delivery of drug through buccal mucosa provides potential advantages like prevention of enzymatic degradation in gastro intestinal tract and bypassing hepatic first-pass metabolism. However the significant aspect in transbuccal drug delivery is the very restrictive passage of drug through the buccal mucosa. In our earlier work we confirmed the ability of Carbamazepine (CBZ) to permeate through the porcine buccal mucosa. Our earlier study proved that CBZ crosses the membrane by passive diffusion. But the measured Flux (Js) and permeation coefficient (Kp) of CBZ was s p insufficient to achieve plasma therapeutic concentration. In this study an approach was made to improve permeability of CBZ using some bile salts as chemical permeation enhancers like sodium taurocholate (STC) and sodium taurodeoxycholate (STDC) which are capable to lessening the barrier property of the mucosal tissue. These patches were subjected to ex vivo permeation studies. The six buccal patches of CBZ selected from our earlier reported formulations were subjected to this permeability improvement study. These patches were either based on HPMC K15M or Carbopol 934p or Chitosan in combination of PVA or PVP K30 or Sodium alginate. The significant change in Js and Kp of formulations in presence and absence of chemical permeation enhancers STC or STDC (in two different p concentrations 0.1% and 0.5 % w/w) was evaluated by ex vivo permeation studies through porcine buccal mucosa under modified Franz diffusion cell. The calculated value of Flux (Js) and Permeation coefficient (Kp) confirmed that s there was a significant increase in permeated amount of CBZ after the inclusion of permeation enhancers. The compatibility of bile salts with buccal mucosa was examined by histological studies and kinetic studies.

  • Profile of Microvascular Complications in Newly Diagnosed Type 2 Diabetics
           and its Association with Correlates of Metabolic Syndrome in a Tertiary
           Hospital: An Observational Study

    • Authors: Nikhitha Chandrashekar, Nivedita Maity, Pramila Kalra
      Abstract: Aim: The primary objective was to study the profile of microvascular complications in newly diagnosed type 2 diabetics in a tertiary hospital and to determine its association with correlates of Metabolic Syndrome.Settings and Design: This was a prospective observational study conducted over a period of six months among patients attending the Endocrinology outpatient of a tertiary care centre in a South Indian city.Materials and Methods: We studied the correlation of microvascular complications (neuropathy, nephropathy, retinopathy and foot ulcers) in 44 newly diagnosed type 2 diabetics with associated risk factors i.e., hypertension, obesity and dyslipidemia.Results: The prevalence of peripheral neuropathy, nephropathy and retinopathy was 15.9%, 2.3% and 2.3% respectively. The study showed that out of 44 patients, 18 had hypertension (40.91%). Four out of the 18 hypertensive patients had microvascular complications (22.2 %). There was a significant association between obesity and peripheral neuropathy (P< 0.05).Conclusion: There was a maximum prevalence of peripheral neuropathy amongst the newly diagnosed diabetics thus they should be wary of the corresponding symptoms of numbness and tingling of feet. It was seen that out of the total 44 diabetic patients, 9.09% had both hypertension and microvascular complications. The low percentage is because 52% of the total hypertensives were on antihypertensive medication. There was also a significant association between obesity and neuropathy. Thus, those with obesity and hypertension are at a high risk of developing microvascular complications.

           Phenylbutazone Induced Chronic Ulceration in Experimental Animals

    • Authors: Bhupesh Kumar Vema, Alok Mukerjee, Amita Verma, Shanti Bhushan Mishra, Alka Verma
      Abstract: Purpose: The objective of the study was to investigate the possible effects of 50% ethanolic extract of Capparis zeylanica (CZE) on gastric secretion and Phenylbutazone ulcer in rats. Approach: Twenty four adult male rats were used in this study (four groups) and several parameters were determined to assess any degree of protection. The ulceration was induced by Phenylbutazone at a dose of 100 mg/kg b.w.Findings: Phenylbutazone toxicity induced + CZE treated rats showed a significant decrease (p > 0.001) in volume of gastric juice, free and total acidity, pepsin concentration and acid output with a significant increase (p > 0.001) in pH compared to Phenylbutazone toxicity induced rats. Phenylbutazone caused a significant decrease (p > 0.001) in TC:P with a concomitant increase (p > 0.001) in protein and DNA. After treatment of CZE in rats, a significant increase (p > 0.001) in the carbohydrate concentration in terms of TC:P ratio and significantly lowered (p > 0.001) protein concentration in gastric juice was observed. CZE tended to increase mucin activity in Phenylbutazone + CZE group.Conclusion: It can be concluded that CZE imparted a protective action against phenylbutazone induced chronic ulcer in rats.

      Abstract: Purpose: A Drug Master File (DMF) is a submission to the Food and Drug Administration (FDA) that may be used to provide confidential detailed information about facilities, processes, or articles used in the manufacturing, processing, packaging, and storing of one or more human drugs. The submission of a DMF is not required by law or FDA regulation, it is submitted solely at the discretion of the DMF holder. The DMF contains factual and complete information on a drug product's chemistry, manufacture, stability, purity, impurity profile, packaging, and the cGMP status of any human drug product. The present work gives the Detailed idea on how to file Drug Master File in US, EUROPE, CANADA, AUSTRALIA.Approach: A Drug Master File is a submission of information to the FDA to permit the FDA to review this information in support of a third party's submission without revealing the information to the third party. In US, DMF filing was done through NDA for drugs, ANDA for generics and BLA for Biologics. In Europe, DMF filing was done through MAA via centralized procedure for eligible products and for other products via decentralized procedure was used. In CANADA, DMF filing was done through NDS for both drugs and biologic products, where as in AUSTRALIA different application processes and regulatory requirements apply depending on the type of therapeutic goods that is applied.Findings: This gives you clear vision on how to file Drug master file in US, EUROPE, CANADA and AUSTRALIA. This paper also gives you the comparison of DMF fling procedure in the above-mentioned countries so that reader can have clear idea on how to file DMF and different concerns on DMF among the above counties.Conclusion: The DMF contains factual and complete information on a drug product's chemistry, manufacture, stability, purity, impurity profile, Packaging and the cGMP status of any Drug product for humans. The content and the format for Drug Master File is used to obtain marketing Authorization. The main objective of the DMF is to support regulatory requirements of a medicinal product to prove its quality, safety and efficacy. This helps to obtain a marketing authorization grant. Now from 2016 onwards most of the regulated countries will use eCTD or their electronic format for their DMF submission.
