Tablet splitting is used in pharmacy practice to adjust the dose to be administered. It is also being advocated as a method of reducing prescription drug costs. ⋯ Tablet splitting appears to have limited usefulness as a cost-reduction strategy. Only a small proportion of products are suitable for splitting and have the potential for savings. There are also costs arising from splitting tablets in the pharmacy, or instructing patients to do so, and from wastage of product. There are also issues such as patient compliance and the risk of an incorrect dose being taken that should be considered.

To measure preferences and willingness to pay (WTP) for a novel anaesthetic (dental gel) versus existing anaesthetic options for periodontal maintenance visits. ⋯ In this population, an alternative to traditional injectable local anaesthetic (i.e. dental gel) was overwhelmingly preferred by both general population participants and recall patients for maintenance cleaning procedures. Most participants were willing to pay to have dental gel available, either for themselves or for others.

Spending on outpatient prescription drugs in the US is accelerating rapidly. Although numerous factors are driving this trend, attention has recently focused on the role played by the marketing, promotion and advertising of pharmaceuticals, in particular direct-to-consumer (DTC) advertising. In 1997, the US Food and Drug Administration (FDA) issued a 'guidance' on such mass media promotion. ⋯ This spending in 1999 was heavily concentrated on about 50 drugs. Evidence is growing that DTC promotion of prescription drugs is: (i) alerting consumers to the existence of new drugs and the conditions they treat; (ii) increasing consumer demand for many drugs; (iii) contributing increasingly to the recent sharp increase in the number of prescriptions being dispensed; (iv) raising sales revenues; and, thus, (v) contributing to the higher pharmaceutical costs of health insurers, government and consumers. The public policy issues surrounding DTC advertisements centre on the following questions: (i) are the advertisements leading to the inappropriate clinical use of some drugs? (ii) are the advertisements inducing both consumers and physicians to choose more costly new brand-name drugs over less expensive, but equally effective, older brand or generic drugs? (iii) do television advertisements for prescription drugs contain a balanced amount of information on benefits versus potential adverse effects? and (iv) will the revenue benefits generated by DTC advertising cause pharmaceutical companies to focus more on developing products to treat prevalent but not life-threatening conditions, such as baldness, sexual dysfunction or memory loss? These questions are just beginning to be probed despite prescription drug spending, insurance coverage and payment policies having become major political issues in the US.

Piperacillin/tazobactam is a beta-lactam/beta-lactamase inhibitor combination with a broad spectrum of antibacterial activity against most Gram-positive and Gram-negative aerobic bacteria and anaerobic bacteria. Piperacillin/tazobactam is effective and well-tolerated in patients with lower respiratory tract infections (LRTI), intra-abdominal infections, skin and soft tissue infections, and febrile neutropenia. In comparative clinical trials against various other antibacterial regimens, piperacillin/tazobactam has shown higher clinical success rates, particularly in the treatment of patients with intra-abdominal infections and febrile neutropenia. Cost analyses of piperacillin/tazobactam have been variable, in part, because of differences in specific costs included. Three US cost analyses found that piperacillin/tazobactam had lower total medical costs than clindamycin plus gentamicin or imipenem/cilastatin in intra-abdominal infections, and ticarcillin/ clavulanic acid in community-acquired pneumonia. Piperacillin/tazobactam plus amikacin had lower total costs than ceftazidime plus amikacin in another cost analysis of patients with febrile neutropenic episodes modelled in nine European countries. However, piperacillin/tazobactam plus tobramycin was more costly than ceftazidime plus tobramycin in hospital-acquired pneumonia in a US cost analysis. In cost-effectiveness analyses, all studies of intra-abdominal infections, pneumonia and febrile neutropenic episodes consistently reported lower costs per unit of effectiveness versus comparators. Piperacillin/tazobactam was dominant (greater efficacy and lower costs) versus imipenem/cilastatin in intra-abdominal infections and ceftriaxone, ciprofloxacin or meropenem in pneumonia. Piperacillin/tazobactam plus amikacin was dominant over ceftazidime plus amikacin in the treatment of febrile neutropenic episodes. In a cost-effectiveness analysis of skin and soft tissue infection, piperacillin/tazobactam had lower costs per successfully treated patient than ceftriaxone or cefotaxime, but a slightly higher cost-effectiveness ratio than amoxicillin/clavulanic acid. All cost-effectiveness analyses were based on decision-analytical models. ⋯ Piperacillin/tazobactam is likely to reduce overall treatment costs of moderate to severe bacterial infections by increasing initial treatment success, thereby reducing the length of hospital stay and the use of additional antibacterials. Piperacillin/tazobactam has shown clinical and economic advantages over standard antibacterial regimens in the treatment of intra-abdominal infections, LRTIs, febrile episodes in patients with neutropenia, and skin and soft tissue infections, although more complete published data are needed to confirm these results. Present data regarding clinical efficacy, bacterial resistance and costs would support the use of piperacillin/tazobactam as an empirical first-line option in moderate to severe bacterial infections.

Outpatient parenteral antibiotic therapy (OPAT) programmes have become prevalent over the past 2 decades. From the US perspective, these programmes have been shown to reduce healthcare costs. No comprehensive analysis has been published from the Canadian perspective. ⋯ This analysis supports the premise that an adult OPAT programme can substantially reduce healthcare costs in the Canadian healthcare setting.
