Methods: The price of different brands of the same anticancer medicines available in the hospital pharmacies of two cancer hospitals was assessed. Prices of different dosage forms such as a single tablet, capsule and vial were calculated. The difference in the maximum and minimum price of the same drug manufactured by different pharmaceutical industries was determined, and the percentage variation in price was calculated. The prices of medicines (brands) were also compared with the price determined by the government where available.
Results: Price variation was assessed for 31 anticancer medicines belonging to six broad categories. Prices were found to vary maximally among the following medicines, each belonging to separate categories: among alkylating agents, the price of temozolomide 100 mg capsule varied 308%; among antimetabolite agents, the price of pemetrexed 500 mg injection varied 134%; among hormonal drugs, the price of letrozole 2.5 mg tablet varied 200%; among antibody class, the price of trastuzumab 440 mg injection varied 73%; among natural products, the price of irinotecan 100 mg injection varied 590%; and among miscellaneous agents, the price of bortezomib 2 mg injection varied 241%. There was a significant difference in the mean MRP of the alkylating agents with the antimetabolites (p-value 0.006) and the monoclonal antibody (p-value
METHODS: The Pub med data base was searched for human clinical studies, reviews pertinent to application of green tea polyphenols in periodontal health dating from Sep 1980- Sep 2014.
RESULTS: The retrieved inference from the epidemiological surveys, in vitro studies and overviews of polyphenols, postulate green tea as potential natural antioxidant. Green tea mouthwashes possess limitations, which make them ineffective during the chronic stages of periodontitis. Human studies reveal that the prognosis of periodontal disease is better when the green tea catechins are used via local drug delivery.
CONCLUSION: The maintenance of periodontal health could be enhanced by emphasizing the habit of drinking green tea in periodontitis patients. The future scope of the research demands the analysis of polyphenols at molecular level to have a better understanding of its overwhelming applications.
