At the moment of her death nobody made the connection about cisapride of which she had been prescribed and taken three full suspension doses for three weeks ; of intensive therapy.
Population Differences: Male or African American patients have been found to prefer to undergo aggressive care when faced with terminal illness, to prefer life-sustaining care, and to die in a hospital.9, 10 It also has been found that patients without Medicare coverage or with hematologic malignancy are more likely to die in an acute care facility. Significant Opportunity for Improvement: As provided by the developer, the proportion of cancer deaths in acute care facilities is 2.49 times higher in HCSAs in the 5th percentile compared to those in the 95th percentile. Stakeholder Interests: This measure would be of particular interest to those consumers with an expressed preference to die at home and to payers to reduce costs associated with overuse. SPECIFICATIONS MEASURE ; Numerator: Patients who died from cancer in an acute care hospital.
Begun acting "out of it, " had difficulty walking, complained of headache, and then became dyspneic. They became worried by these symptoms and contacted emergency medical services. Given this new information about the patient's neurologic problems, her physicians order immediate computed tomography of the head, which reveals subarachnoid hemorrhage, likely originating from an aneurysm at the superior aspect of the basilar artery. A neurosurgeon performs an emergency ventriculostomy at the bedside to relieve her hydrocephalus. Within hours, the patient is weaned from vasopressors, intraaortic balloon counterpulsation is discontinued, her supplemental oxygen requirements decrease, and her cardiac index increases to 3.0. On the second hospital day, the patient undergoes coil embolization of the basilar artery aneurysm. A new electrocardiogram done on that day shows that the initial changes have resolved FIGURE 5 ; , and transthoracic echocardiography reveals a nearly normal left ventricular ejection fraction. By the 20th day of her hospital stay, the patient is feeling well and has undergone a remarkable neurologic recovery without focal physical weakness and with only mild memory deficits surrounding the sentinel event. FINAL POINTS This patient's case highlights the neurocardiac axis. Subarachnoid hemorrhage and other cerebral insults can be associated with electrocardiographic changes, systolic dysfunction, and release of biomarkers of myocardial necrosis. While not completely elucidated, the pathophysiology of this relationship seems to be the result of catecholamine effects on the myocardium, and is manifest histologically as contraction band necrosis. Research is REFERENCES, for example, side effect.

| Besides building a portfolio of strong patents, fully exploring the form and formulation space could result in a secondary benefit: discovering a superior product. Getting to that point isn't cheap, as Sepracor found out. More than a decade after it patented its single-isomer forms of existing drugs, it's only been able to prove significant differences among a small handful at a cost of hundreds of millions of dollars. Some of its licensing partners have taken its products forward; others have not: Lilly in-licensed Sepracor's single-isomer version of fluoxetine Prozac ; , abandoning the project when it evidenced problems at high doses. Likewise, J&J's Janssen Pharmaceutica NV unit licensed Sepracor's ticalopride originally called norcisapride ; as a replacement for cisapride Propulsid ; , which had been pulled from marketing for adverse effects. But Janssen had to pull ticalopride from Phase II trials when it, too, exhibited serious side effects. Nonetheless, the failures in Sepracor's business have been more than outweighed by the successes: Sepracor today sells a single-isomer version of albuterol called levalbuterol Xopenex ; , is awaiting approval of the sleep drug eszopiclone Estorra ; , and has a number of others in late-stage trials. Its market cap, about $1.69 billion. The larger generic companies--for example, Andrx Corp., Ivax, Apotex Inc., Barr Laboratories Inc., Mylan Laboratories Inc., Teva, Watson Pharmaceuticals Inc., Biovail Corp., and Reddy--certainly have the financial resources to do similar development, meanwhile challenging innovators' patents in more aggressive ways, forcing more of their offerings onto the market. See Exhibit 5. ; Indeed, while TransForm has not gone after the generic market, its technology--or Symyx's, or the technology of competitors that come along--could eventually become available to financially strong generic firms, giving them the same technological window into the problem as proprietary drug firms have. The likelihood that an unknown polymorph, salt, or other form of an existing product will turn into a significant improvement over the original drug is small. But as the Sepracor experience shows, just a few winners can create substantial value. Indeed, the Sepracor story proffers an intriguing and applicable side strategy. Hoechst Marion Roussel, one of the predecessor companies of Aventis, first turned to Sepracor for help when Seldane received a black box warning from the FDA: rare but dangerous interactions between Seldane, certain antibiotics, and antifungals led to potentially fatal cardiovascular problems. Once HMR introduced Sepracor's Allegra--a nearly identical alternative to Seldane, but without the side effects--it was also able to get the Since 1989 Windhover Information Inc. has been dedicated FDA to withdraw Seldane's approval, in the process dramatically exto providing superior analysis and commentary on health care market trends, company strategy, emerging tending the patent life of its antihistamine franchise. technologies dealmaking, and key industry events. A situation in which a company can actually get its own product withReaching senior executives and top industry observers drawn in favor of a longer-lived substitute is certainly rare, just as is the around the world, Windhover's products and services likelihood of finding a chemical polymorph which substantially improves include monthly newsletters, annual reference guides, web & on the original. But given the value of such a product, and such a patent desktop databases, and a full range of industry conferences. extension, it would be foolhardy for the industry not to be spending subWindhover's expertise spans the pharmaceutical, biotech, stantial time exploring the often invisible value of polymorphs, salts, and medical device and equipment, hospital supply, other solid forms inherent in their own products. and in vitro diagnostics industries.

One or more of the metabolites described by Meuldermans et al. 1988a, b ; . We speculate that UNK may correspond to the metabolite of unknown structure because, in other mammalian species, the formation of the two lactam metabolites is catalyzed not by P450 enzymes but by cytoplasmic molybdenum hydroxylases Lavrijsen et al., 1986 ; . Second, the other CYP3A enzymes examined i.e., CYP3A5, an isoform found in 20% of adult human livers, and CYP3A7, the fetal CYP3A isoform ; catalyzed rates of metabolite formation that were at least 100- and 50-fold lower, respectively, than those catalyzed by CYP3A4. In addition, at pharmacologically relevant concentrations of cisapride, CYP3A7 appeared to catalyze little or no hydroxylation of csapride to 3F or 4F. Therefore, CYP3A5 and CYP3A7 do not appear to be capable of catalyzing the biotransformation of cisapridde to any appreciable extent. The results of this study demonstrate that CYP3A4 is the P450 enzyme primarily responsible for the metabolism of cisapride and ; -norcisapride. CYP3A4 is characterized by marked interindividual variability in both enzyme content and activity up to 10- and 20-fold, respectively ; , is the predominant P450 present in adult human liver Shimada et al., 1994 ; , and is highly expressed in human small intestine Thummel et al., 1994 ; . The fetal CYP3A isoform CYP3A7 accounts for 30 to 50% of total hepatic P450 content in the fetus. Shortly after birth, activity switches from CYP3A7 to CYP3A4 Lacroix et al., 1997 ; , although CYP3A7 may be expressed to varying degrees in the adult liver Schuetz et al., 1994 ; . Livers from infants at 1 month of age possess approximately 30% of the CYP3A4 activity associated with adult livers. Hepatic CYP3A4 activity in infants appears to approach adult levels of activity by 6 to months of age Lacroix et al., 1997 ; and may even exceed adult levels of activity between 1 and 4 years of age on the basis of pharmacokinetic data for known CYP3A substrates Leeder and Kearns, 1997 ; . Previous clinical data and the in vitro results presented here and by others Bohets et al., 2000; Desta et al., 2000 ; strongly implicate CYP3A4 as the enzyme responsible for catalyzing the biotransformation of cisapride to its major metabolite, Nor. The results of this study also suggest that CYP3A4 is primarily responsible for the conversion of cisapride to the minor metabolites 3F and 4F. Also, our in vitro results demonstrate that CYP3A7 does not catalyze the biotransformation of cisapride to Nor, 3F, or 4F to any appreciable extent. Based on these observations, one would anticipate that the developmental pattern of cisapride biotransformation would reflect CYP3A4 ontogeny, thereby placing the most immature infants at the greatest risk for serious cardiac adverse effects associated with an accumulation of cisapride in plasma. However, this anticipated pharmacokinetic pattern was not observed in a study of 37 neonates and young infants who were given cisapride 0.8 mg kg day ; , which produced plasma concentrations following an initial dose similar to those observed in adults taking therapeutic doses of the drug Kearns et al., 2001 ; . It should be noted, however, that the plasma concentrations of cisapride found in neonates might be affected by differences in the relative contribution of intestinal and hepatic CYP3A isoforms to its metabolism during the first few months of life, particularly since the drug is administered orally. To date, the developmental pattern of intestinal CYP3A expression has not been characterized. In contrast to the situation with cisapride, clinical data and our own in vitro studies have shown that the biotransformation of ; -norcisapride to its metabolite or metabolites ; proceeds extremely slowly. Clinical studies have further shown that ; -norcisapride is extensively excreted unchanged by renal mechanisms Meuldermans et al., 1988b ; . Therefore, factors related to CYP3A4-mediated metabolism e.g., ontogeny of CYP3A enzymes, inhibition, induction, etc. ; will be clinically unimpor.

Overview Patients in the hospital experience acute pain from operative and non-operative procedures, and from a variety of medical conditions. To provide optimal analgesia and facilitate recovery and discharge, it is critical to prescribe and administer the appropriate analgesic regimen. While the traditional approach was to use "prn" parenteral or oral analgesia, requiring patients to ask for medication when needed, this approach is now considered outdated, and a proactive approach to pain control is the new standard.9 This section offers a model for determining an appropriate oral analgesic regimen to be used while the patient is in the hospital and after discharge. The method can be used to support a clinical decision-making process based on evaluating multiple variables that impact the quality of pain care. These variables are outlined below. Because evidence-based guidelines on the specific management of pain are largely unavailable, the information presented is based on a consensus of the advisory panel.

Pharmacology - Cisapride: In order to assess hERG potassium pharmacology, the gastrointestinal prokinetic cisapride was selected. This compound is a potent hERG channel blocker with a reported IC50 value in the low nanomolar range see below ; . The reported IC50 values are highly dependent on the voltage protocols used. However when the voltage is stepped to depolarized levels greater than + 20 mV, assessment of the reduction in tail current amplitudes on stepping back to negative potentials -40 -50 mV ; produces similar IC50 values; i.e. 7-44 nM Rampe et al., 1997 ; , 7 nM Mohammad et al., 1997 ; and 20 nM Walker et al., 1999 ; . In this study, bath application of cisapride Figure 6, 3 and 30 nM ; inhibited the tail current amplitude by 51.4 3.0% and 89.5 0.7% respectively n 3 cells ; . Thus, the extent of block seen is similar to the published reports described above.
Of drugs dependent on CYP2C19, which metabolizes phenytoin Dilantin ; , phenobarbital, omeprazole Prilosec ; , and other drugs.9 Variance in drug response among persons of different ethnic origins also can be caused by genetic variations in other drug-metabolizing enzymes, drug transporters, and drug receptors.3 DrugInteractions Many drug interactions are the result of an alteration of CYP450 metabolism.10 The nonsedating antihistamines terfenadine Seldane ; and astemizole Hismanal ; , and the gastrointestinal motility agent cisapride Propulsid ; , were all withdrawn from the U.S. market because metabolic inhibition by other drugs led to life-threatening arrhythmias.11 The calcium channel blocker mibefradil Posicor ; was withdrawn from the U.S. market in 1998 because it was a potent enzyme inhibitor that resulted in toxic levels of other cardiovascular drugs.12 Drugs interact with the CYP450 system in several ways. Drugs may be metabolized by only one CYP450 enzyme e.g., metoprolol by CYP2D6 ; or by multiple enzymes 392 American Family Physician.
