ESTATIONAL trophoblastic disease GTD ; consists of a group of diseases ranging from hydatidiform mole to choriocarcinoma. All patients in the United Kingdom diagnosed with GTD are referred to one of three centers for beta human chorionic gonadotropin hCG ; monitoring and, if necessary, to one of the two centers for treatment. In our center, patients who require treatment criteria: serum hCG 20, 000 IU L 4 weeks after uterine evacuation, static or rising hCG after uterine evacuation, persistent hemorrhage, presence of metastatic disease, diagnosis of choriocarcinoma ; are stratified according to the Charing Cross scoring system Table 1 ; . This scoring system was devised as a way of stratifying patients into treatment groups according to known adverse prognostic factors rather than by strict anatomic definitions. Previously, three prognostic categories were used, namely, high score, for example, cetirizine hcl generic.

1998 ; . For this reason, the SH-SY5Y clone of human neuroblastoma cells was used to compare the effects of the four different H1 receptor blockers on mammalian cells that constitutively express HERG K channels. Due to the simultaneous expression of various classes of K channels in these cells, IHERG was studied by means of a voltage-clamp protocol in which the cell was depolarized for 10 sec to 0 mV, a membrane potential that fully activated IHERG and completely inactivated the delayed rectifier K current and then repolarized to increasingly negative voltages from 0 to 140 180 mV ; for 100 msec. Using this voltage protocol, it is possible to detect a K -selective inward tail current displaying the biophysical properties of IHERG Arcangeli et al., 1995; Bianchi et al., 1998 ; . The relatively small density of HERG K channels in SH-SY5Y human neuroblastoma cells required the use of a high 100 mM ; external K concentration as a charge carrier. Fig. 2C summarizes the percent of inhibition of IHERG by the same concentration 3 M ; of the four second-generation antihistamines examined in several SH-SY5Y human neuroblastoma cells. In analogy to the results obtained in oocytes, superperfusion with astemizole or terfenadine for 38 min caused an almost complete suppression of the inward tail current of IHERG 80% blockade ; . On the other hand, the same concentration of loratadine caused a 40% blockade of IHERG, whereas cetirizine 3 M ; was completely devoid of any inhibitory action. Differential effect of the intracellular and extracellular applications of astemizole and cetirizine on IHERG heterologously expressed after stable transfection of HEK 293 cells with HERG cDNA. The hypothesis that the lack of inhibitory action of cetirizine on IHERG in both X. laevis oocytes and SH-SY5Y human neuroblastoma cells was caused by the relatively poor access of the drug to its putative intracellular receptor site on the channel has been investigated in a subsequent series of studies. To this aim, HEK 293 cells stably transfected with HERG cDNA Zhou et al., 1998 ; were used. In fact, in these cells the 50 times higher density of IHERG compared with the SH-SY5Y human neuroblastoma cells Taglialatela M, unpublished observations ; allows the adequate recording of IHERG with lower concentrations of extracellular K 10 mM ; Using this extracellular K concentration, it is possible to obtain stable recording conditions lasting several minutes up to 1 and to resolve outward K currents carried by HERG channels. Fig. 3A shows representative current traces from the same HERG-transfected HEK 293 cell subsequently recorded in control conditions and after 5 min of extracellular 3 M cetirizine perfusion. In accordance with the results obtained in X. laevis oocytes and SH-SY5Y human neuroblastoma cells, cetirizine failed to affect inward and outward IHERG. After a 5-min perfusion with 3 M cetirizine, the inward component of IHERG in HERG-transfected HEK 293 cells was blocked by 1 4.6% five determinations; p 0.05 ; . By contrast, 3 M astemizole blocked 91.8 2.5% of the control inward current recorded before astemizole superfusion eight determinations; p 0.05 ; . It should be emphasized that the small residual outward and inward K currents recorded after prolonged 5 min ; perfusion with astemizole are likely to be carried by outwardly rectifying K channels constitutively expressed in HEK 293 cells, presumably of the delayed-rectifier type. This current does not seem to be related.
Ketoconazole, cyclosporine or verapamil; of PgP substrates and inhibitors such as erythromycin, azithromycin, verapamil or itraconazole; or of PgP inducers such as verapamil or rifampicin [72] since most if not all ; of them are PgP substrates to one degree or other. Fexofenadine is a potent PgP substrate, and as such much of its bioavailability and clearance depend on this transport system [11]. Drugs or substances that are able to induce PgP, such as rifampicin, yield a lesser concentration of fexofenadine when co-administered with the latter drug; pharmacological interaction therefore exists in this case. The result of this interaction is a decrease in fexofenadine efficacy [34]. Loratadine may act as both a substrate and potent inhibitor of PgP, though to a lesser degree than verapamil or cyclosporine; the possibility of pharmacological interactions therefore exists [73]. The interaction of desloratadine with other drugs at PgP level cannot be ruled out, since it is a PgP substrate even though it does not inhibit the latter; it therefore does not seem responsible for possible interaction [73, 74]. The information on mizolastine is scarce and limited to an increase in plasma levels of digoxin a typical PgP substrate. Consequently, mizolastine would appear to behave as a PgP inhibitor [75]. Levocetirizine is a weak PgP substrate, it being unlikely for the drug to interact with other substances at this level, according to the study model involved Caco-2 cells ; . The same consideration applies to cetirizine [76]. However, cetirizine has also been investigated in another model a murine model involving the canceling of PgP expression ; , showing it to be clear PgP substrate [77]. As a result, possible interaction with other drugs at this level acquires increased relevance. Terfenadine and ebastine have shown their PgP inhibitory effect and capacity to interact with other drugs that function as PgP substrates; they may thus revert multipharmacological resistance [78, 25].
Zanamivir for inhalation Relenza, GlaxoSmithKline ; has been approved to prevent influenza in adults and children five years of age and older. This antiviral medication was previously approved to treat influenza A and B virus infections in this population. The new approval for prevention provides another option in addition to oseltamivir phosphate Tamiflu, Roche ; , which is indicated for both preventing and treating the flu. The effectiveness of zanamivir was demonstrated in four large-scale studies. This drug is not recommended to treat or prevent seasonal influenza in people with asthma or chronic obstructive pulmonary disease, and it is not a substitute for the flu vaccine. In preparation for a potential pandemic, the FDA has assembled a task and cinnarizine.
Firstly, Martin et al. 1998 ; tabulate statistics on only the proteins in the PDB. They found a clear alpha beta preference for proteins in the oxidoreductase, transferase, and hydrolase categories EC 1-3 ; , but for the lyase, isomerase, and ligase categories EC 4-6 ; they observe different tendencies. However, they did not have sufcient counts to establish statistical signicance for this latter nding. This is basically what we observe in Figure 4 b ; . ; Because in our analysis we use all of Swissprot and we tabulate our statistics a little differently in terms of combinations ; , we get more ``counts'' than Martin et al. 1998 ; . Thus, we are able to argue that the different distribution of foldfunction combinations observed for lyases, isomerases, and ligases are signicant. This is borne out by the chi-squared statistics at the end of Table 2. Secondly, Martin et al. ``no-relationship'' conclusion applies only to comparisons between the different enzyme classes. However, we nd our largest differences when comparing non-enzymes to enzymes and also comparing between the various types of non-enzymes. Finally, the CATH classication that Martin et al. use has only three classes in its top-most level. In contrast, SCOP has six top classes Table 1 ; . While this larger number of categories does tend to degrade our statistics somewhat, it also highlights some differences that cannot be observed in terms of the CATH classes alone, e.g. we nd clear differences between alpha beta and alpha beta proteins and also between small proteins and all others. Apparently high occurrence of convergent evolution Note that the table in Figure 2 is not square: it has more folds than functions. This shape leads to a number of interesting conclusions. The 331 foldfunction combinations we observe for 229 folds and 92 functions imply that there are 1.2 functions per fold and 3.6 folds per function. However, these numbers are somewhat skewed by the large number of folds 101 ; associated only with the single non-enzymatic function. If we exclude these, we get 128 ``enzyme-related'' folds, which are, in turn, associated with 230 331 101 ; different foldfunction combinations. This implies that for the enzyme-related folds there are on average 1.8 functions per fold and 2.5 folds per function 230 128 and 230 92 ; . The larger number of folds per function than functions per fold seems to suggest that nature tends to reinvent an enzymatic function i.e. convergent evolution ; more often than modify an already existing one i.e. functional divergence ; . How can we explain this? Firstly, 1.8 is a lower estimation for the number of functions per fold as the non-enzymatic functions were bundled into one group here. Secondly, there are several examples of functional divergence for a fold within one three-component enzyme category that are not.

The drug was administered daily for up to 4 weeks, whereas safety in children 611 years of age is based on placebo-controlled and uncontrolled clinical studies in which 5 or 10 mg of the drug was administered orally daily for up to 4 weeks, respectively. Recommended pediatric doses are based on crossstudy comparisons of the pharmacokinetics and pharmacodynamics of cetirizine in adults and children and on safety profiles of the drug from studies in adults and children at recommended or higher doses and propulsid.
Loratadine vs cetirizine
Little is known about the safety of hydroxyzine use during pregnancy, and there are no published reports on the effects of cetirizins on pregnancy outcome.
Rhinitis treatment Levocetirizine is the R or active enantiomer of cetirizine, which is itself an active metabolite of hydroxyzine, a first-generation antihistamine. Levocetirizine is reported to have less cerebral histamine receptor binding than the racemic compound, which would result in reduced central nervous system side effects. A 6-month placebo-controlled study of levocetirizine was conducted in Europe in 551 subjects with allergic rhinitis.19 The symptomatic response to active treatment was rapid and sustained. At 4 weeks, reduction in total nasal symptom score with levocetirizine including congestion ; was 18% more than that in the placebo group, despite the use of less rescue medication. The Juniper rhinitis-specific quality of life score also improved by 0.48 compared with placebo 0.50 is considered a clinically meaningful change ; . Improvement in individual symptoms generally paralleled total symptom score except for nasal congestion, which improved significantly in the levocetirizine group only from 3 months on. The only difference in side effects was with somnolence, which was reported by 1.8% of the placebo and 6.8% of the levocetirizine subjects. However, further analysis revealed that the total duration of combined fatigue, asthenia, and somnolence in the 2 groups was similar, 3.26 days per 100 days in the placebo group and 3.72 days per 100 days in the levocetirizine group. Levocetirizine was compared with desloratadine and placebo in a crossover nasal challenge study in 24 subjects.20 Single doses of each drug were administered, followed by a nasal challenge with increasing doses of grass pollen extract. Both antihistamines were more effective than placebo P , .001 ; . Desloratadine increased the threshold by 1.93 allergen doses, whereas levocetirizine and clemastine.
ATC code: R06AE07 Pharmacotherapeutic group: Antihistamines for systemic use Xetirizine dihydrochloride is a racemate and an anti-allergic with specific histamine H1receptor blocking characteristics. Cetirixine inhibits cutaneous reactions in allergic individuals by VIP Vasoactive Intestinal Polypeptide ; and the P substance, neuropeptides that are considered involved in the allergic reaction. Effect is reached within 2 hours with a maximum effect after 4 hours, and remains for at least 24 hours. In allergic individuals, cstirizine inhibits the recruitment of eosinophiles after stimulation with allergens and unselective histamine liberators, by a mechanism that is not primarily explained by the H1-receptor blocking characteristics of the pharmaceutical.

Inventorship complexities are typified in a PCT application from Sheffield-based BioActa Ltd relating to a peptide screen. The inventors have residential addresses in Basel a Spaniard ; and the UK Sheffield and Epsom ; , but the attorney responsible for filing the case is located at Novartis, also in Basel. Our researches, based on previous inventorship, indicate that the Spanish inventor is in fact a Novartis employee, and that in October 2001 BioActa, a University of Sheffield spin-off, announced a collaborative research and license agreement with Novartis to investigate novel therapies for the treatment of angiogenesis-related diseases. The Epsom address corresponds to the company's Chairman. BioActa employs the research of professors Brown and Lewis, specifically the proprietary fibrinogen fragment Alphastatin. Our DOLPHIN database points to WO0188129 and WO0218440 as significant cases leading up to the present one. UCB also raises SPC issues, indirectly, in a process case concerned with the antihistaminic cetirizine follow-up efletirizine. As basic protection for levo ; cetirizine begins to expire February 2002 onwards ; , emphasis shifts to the SPCs based on EP58146, expiring in 2007 in the UK, for example. Marketing approval for efletirizine, and the grant of the pseudopolymorph case EP919550, might in the near future trigger an SPC application for this related active.
