The efficacy of granisetron in preventing acute nausea and vomiting during the 24 hours following chemotherapy in patients with cancer is equivalent to that of other serotonin 5-HT3 receptor antagonists (ondansetron and tropisetron) and similar to or greater than that of conventional antiemetic regimens such as metoclopramide plus dexamethasone. Like other 5-HT3 receptor antagonists, granisetron is generally well tolerated by most patients and its antiemetic efficacy is enhanced when used concomitantly with dexamethasone. To date, pharmacoeconomic evaluations of granisetron have involved intravenous administration of the drug to adult patients with cancer receiving single-dose or fractionated chemotherapy of moderate to high emetogenic potential. ⋯ Granisetron also remained more cost effective than ondansetron with variations in the antiemetic dosage regimens, except when the granisetron dosage remained unchanged while the ondansetron dosage was reduced to a single 8mg intravenous dose on each day prior to chemotherapy (and no change in efficacy was assumed). Other economic evaluations suggest that granisetron may be more cost effective than a combined antiemetic regimen of high dose metoclopramide plus dexamethasone, and selected use of granisetron or ondansetron in patients receiving emetogenic chemotherapy can be implemented with relatively small incremental increases to the total cancer treatment budget, albeit with a marked increase in antiemetic acquisition costs. In conclusion, granisetron is an effective and well tolerated agent for the prophylaxis of acute chemotherapy-induced nausea and vomiting, and its selective use in this clinical setting can provide cost-effective antiemetic therapy.

Propofol is an intravenous anaesthetic agent that has become widely used in day case surgery. It induces anaesthesia rapidly and 'smoothly', is associated with a quick recovery and has a lower incidence of postoperative nausea and vomiting (PONV) than other agents. In studies comparing propofol with other intravenous anaesthetics (most commonly thiopental sodium) in day case surgery, the use of propofol as induction and/or maintenance anaesthesia was associated with a shorter time to intermediate recovery (street fitness or time to discharge), although the mean time difference was generally less than 1 hour. ⋯ Based on differences in recovery time, 2 studies have estimated a decreased demand for nursing staff time associated with the use of propofol compared with thiopental sodium/isoflurane. In addition, informal patient satisfaction assessments show propofol to be equal to or better than other anaesthetic agents. With these broader considerations, it thus remains for future studies to quantify the intangible and indirect costs associated with propofol anaesthesia, to determine whether differences in recovery between propofol and other agents (especially the newer inhalational anaesthetics) are of economic importance, and to identify those instances where propofol use provides the greatest value for available funds.

Alcohol (ethanol) use disorders are prevalent in many countries and are associated with significant social and health costs. Little is known, however, about the comparative cost effectiveness of treatments for alcoholism. ⋯ We discuss pharmacological approaches to the treatment of alcohol withdrawal and dependence, describing agents that ameliorate withdrawal symptoms, deter alcohol consumption, reduce alcohol craving and produce conditioned alcohol aversion. Cost-relevant clinical considerations are elucidated and recommendations for cost-conscious pharmacological treatment of alcohol dependence are proffered.

The National Health Service (NHS) accounts for more than 98% of the UK prescription medicines market, which is the sixth largest pharmaceutical market in the world. Most of this market is driven by the UK's approximately 35,000 general practitioners (GPs). It is an open market, with most leading foreign pharmaceutical companies having a strong presence. ⋯ The pharmaceutical industry has generally performed relatively well in the UK market, managing to preserve incentives to innovation. This reflects the fact that UK GPs have been able to maintain their clinical freedom, as well as government recognition of the economic contribution made by the pharmaceutical industry. Current issues of interest in the UK pharmaceutical market context include the future of the PPRS, the debates over the imposition of a national formulary and generic substitution, and over parallel trade, the potential impact of managed-care protocols and computer-based prescribing on pharmaceutical expenditures, and possible political changes.
