Tablet splitting Break mark Results: The accuracy and precision of hand broken tablets was 104/97% resp. 2.8/3.2% (one part per tablet Weight uniformity considered; parts right/left side operator). The right/left accuracies of the splitting devices varied between 60 and 133%; the precisions 4.0 and 29.6%. The devices did not deteriorate over 100-fold use. Only hand broken tablets complied with all regulatory requirements. Conclusion: Health care professionals should realize that tablet splitting may result in inaccurate dosing. Authorities should undertake appropriate measures to assure good function of tablet splitters and, where feasible, to reduce the need for their use. ã 2014 The Authors. Published by ELSEVIERCOMPANY.

    Shopping for Drugs

    Shopping for Drugs by Devon Herrick Research Manager NCPA Policy Report No. 262 June 2003 ISBN #1-56808-130-8 Web site: www.ncpa.org/pub/st/st262 National Center for Policy Analysis 12655 N. Central Expressway, Suite 720 Dallas, Texas 75243 (972) 386-6272 Executive Summary As Congress debates ways to lower the cost of prescription drugs for seniors, and state govern- ments debate ways to lower drug costs for almost everyone else, it may be time to consider a commonsense solution: smart shopping. Seniors, the uninsured and others who pay for drugs out of pocket do not have to wait for political solutions to the problem of rising drug prices. By becoming aggressive consumers, they can cut their costs substantially. In fact, the cost of some common drug therapies can be reduced by more than 90 percent using buying techniques consumers normally use to shop for other goods. But they should be forewarned. Patients buying drugs from multiple sources may forgo the safeguard of using a single licensed pharmacist who checks for drug interactions. To ensure this does not occur, patients should make all pharmacies they use aware of all drugs they are taking. Consumers have never had more opportunities to obtain information about drugs. A patient with a prescription can find a range of prices by clicking on a few Internet pharmacy Web sites. The Internet also makes it easy to look up information on government and private programs that assist elderly, low-income and disabled patients with drug expenses. Additionally, Web-based services help patients find medications comparable to but cheaper than the ones they currently take.

    Shopping for Drugs: 2004 by Devon Herrick, Ph.D. Senior Fellow NCPA Policy Report No. 270 October 2004 ISBN #1-56808-139-1 Web site: www.ncpa.org/pub/st/st270 National Center for Policy Analysis 12770 Coit Rd., Suite 800 Dallas, Texas 75251 (972) 386-6272 Executive Summary Seniors, the uninsured and others who pay for prescriptions out of pocket are looking for ways to cope with rising drug costs. While many seniors can lower their drug bills by using the new Medicare discount drug cards and the new subsidies for low income retirees, every patient interested in saving money on drug therapy should consider a common-sense solution: smart shopping. Patients can cut costs substantially by becoming aggressive consumers. In fact, seniors can reduce the cost of some common drug therapies by more than 90 percent if they use the same buying techniques they routinely use when shopping for other goods and services. But they should be forewarned. Patients buying drugs from multiple sources forgo the safeguard of using a single licensed pharmacist who checks for drug interactions. To ensure this does not occur, patients should make all pharmacies they use aware of all drugs they are taking. Consumers have never had more opportunities to obtain information about drugs.
