Suggest that azelastine and fexofenadine should be avoided during pregnancy. Cetirizine or loratadine may be considered for use during pregnancy in women who do not respond to either of the antihistamines of choice chlorpheniramine and tripelennamine ; and who need an antihistamine despite optimal topical therapy. Use during the first trimester should be avoided, however. Asthma management is based on disease severity. The updated recommendations for pregnant women are summarized in Table 2 and mirtazapine.
Patients Table 1 ; .14 These findings strongly suggest caution when prescribing this drug to the elderly. Reports by Mann, et al. of sedation with secondgeneration antihistamines loratadine, cetirizine Zyrtek, Pfizer ; , fexofenadine Allegra, sanofi-aventis ; and acrivastine Sempra, GlaxoSmithKline ; were infrequent, but this study did not focus on the elderly. Affrime et al.15 studied pharmacokinetics and adverse events of desloratadine Aerius, Schering ; in different age groups and suggested that no dosage adjustment of desloratadine is required in the elderly. Immunobiological Agents Three immunobiological agents have been approved by the US FDA for the treatment of moderateto-severe psoriasis: alefacept Amevive, Astellas ; , efalizumab Raptiva, Genentech ; , and etanercept Enbrel Amgen Wyeth ; .16 A recent study found alefacept to be well tolerated and effective in elderly, obese, and diabetic patients with moderate-to-severe plaque psoriasis.17 Accidental injury, headache, and pharyngitis were among the most common adverse events. Infections were primarily colds, with no opportunistic infections being reported. In psoriatic patients 65 years of age treated with efalizumab, the overall rates of adverse events were comparable to those seen in patients 65 years of age, although a higher rate of serious adverse events was observed in the older group.18 References 6, 7 6.

| Generic LoratadineRecurrent Depression: An Overview 19 million Americans--one in ten adults--experience depression each year. According to the World Bank, unipolar major depression is the leading cause of disability in the U.S. and the world. Although treatment can alleviate depressive symptoms in over 80% of the cases, two-thirds of those afflicted with depression will not get the help they need they're either not treated at all, or undertreated ; . Undertreatment results from incorrect or incomplete diagnoses, or inadequate treatment duration. Even people that do get successful help for their depression are not guaranteed smooth sailing. Indeed, for many people, depression is a chronic disease, characterized by repeated episodes of recurrent depression. Although researchers have not identified the trigger that propels people with a history of depression back into depression, they have identified some factors that put certain individuals at risk for a recurrence: People with an incomplete response to antidepressants People with a history of chronic depression or longstanding personality disorder People experiencing interpersonal loss and disappointment * People who receive criticism from others * Evidence-based medicine shows that continuation antidepressant medication the meds used to successfully treat the acute episode ; , and ITP interpersonal therapy.

All the facilities receive data from service records within the facilities. The data was mainly summarized for reports to be forwarded to the next level. Analysis was done at the district office and forwarded to the provincial office. According to the respondents most of the health facilities did not receive feedback, and did not have the analyzed data displayed, for discussion. Almost all the facilities had submitted their reports in the last twelve months. However they all reported shortage of forms as a hindering factor to report submission. Data analysis and usage tended to take place only at DHO. Feedback was not assured but some data were generally displayed as charts and diagrams at the facilities. Many facilities reported shortage of reporting tools. 2.3.3 Drug Management Most of the frequently prescribed drugs were first line drugs for the top five diseases in the facilities. They listed key drugs for malaria, pneumonia, URTI, diarrhea, STI, and skin conditions. Few of the facilities visited had the national drug policy NDP ; .

However, others contest such claims. Based on their study of NGOs' activities at the 1992 Rio summit, the 1993 World Human Rights Conference in Vienna, and the 1995 World Conference on Women in Beijing, Clark, Friedman, and Hochstetler 1998 ; find that NGOs' impacts on policy agendas and outcomes were not significant. Keck and Sikkink 1998: 33 ; , while making a strong case for the impact of transnational advocacy networks on domestic and transnational politics, note the lack of "convincing studies of sustained and specific processes through which individuals and organizations create or resist creation of ; something resembling a global civil society." This paper focuses on how transnational networks of businesses and NGOs seek to influence U.S. policy regarding the establishment and enforcement of an inter-governmental regime TRIPS. 3 They begin their book by noting that "World politics at the end of the twentieth century involves, alongside states, many nonstate actors that interact with each other . These interactions are structured in terms of networks . Some involve economic actors and firms. Some are networks of scientists and experts whose professional ties and shared causal ideas underpin their efforts to influence policy. Others are networks of activists, distinguishable largely by centrality of principled beliefs or values in motivating their formations. We will call these transnational advocacy networks". On page 2, they contrast such networks with business networks and epistemic communities by noting that advocacy networks are "motivated by values rather than by material concerns or professional norms." On page 9, they identify major actors in advocacy networks to include international and domestic non-governmental research and advocacy organizations. trade unions, consumer organizations, and intellectuals. 4 See Katzenstein, et. al., eds., 1999.

Side effects of Loratadine
Oral antihistamines are suitable for the majority of patients particularly when a variety of symptoms are present. Chlorpheniramine is probably the most effective antihistamine with the fastest onset of action. However, it causes drowsiness which has been reported as problematic by 14% of patients in one paper. This effect is short lived as tolerance develops after a few days. Patients should be advised to start taking chlorpheniramine in the evening for the first couple of days in order to see whether they will be affected. Loratadine is a useful alternative when drowsiness is a problem. PRN use of most antihistamines is acceptable for many patients who only experience symptoms in the morning or night and not necessarily both. Consequently a once daily administration regime is not always required. Sodium cromoglycate gives prompt relief and should be used on its own when ocular symptoms predominate or as an adjunct to oral antihistamines when the latter fail to control ocular symptoms. Intranasal beclomethasone should be used on its own when nasal symptoms predominate or as an adjunct to oral antihistamines at times of high pollen counts when antihistamine cover is inadequate.
Non-sedating antihistamines other than cetirizine, fexofenadine and loratasine are not offered as first choice. Desloratadine a metabolite of loeatadine ; and levocetirizine an isomer of cetirizine ; are more recently marketed products and there is little evidence to confirm whether, in practice, they confer any benefit over the more established non-sedating antihistamines [MeReC, 2004]. Mizolastine has been implicated in causing an abnormal prolongation of the QT interval and is not recommended first-line. Acrivastine is not recommended as it has a short half-life and needs to be taken three times a day. Topical antihistamines are not included as they are only marginally effective and may occasionally cause sensitization [BNF 46, 2003]. Long-term oral corticosteroids are not recommended for general use in chronic urticaria.
There is no clinical advantage to switching a patient from loratadine to desloratadine.

Loratadine sale
Histamine plays a crucial role in the pathogenesis of IgE-mediated allergic as well as non-allergic diseases. The inflammatory role of histamine and involvement of different types of histamine receptors is well established. On the same time histamine via its specific receptors may modulate an IgE synthesis and this effect is less investigated. Our data showed that IgE regulation induced by histamine is mediated via H1 and H2 as well as H3 H4 receptors. It has been shown that histamine involves in IgE response not only in allergic diseases allergic rhinitis, asthma, atopic dermatitis ; as well as in non-allergic diseases, such as malignant bone marrow alterations. Histamine-mediated effects on IgE synthesis can be realized in these diseases via not only well-investigated H1 and H2 receptors, as well as via newly discovered and recently cloned H3 and possibly H4 receptors ? ; . IgE synthesis induced by histamine is highly dependent on the concentration of mediator and type of involved receptors. Thus, histamine in high concentrations 10-5M ; suppressed and in low concentrations 10 -8M ; stimulated spontaneous IgE synthesis. Antagonists of H1 loratadine ; and H2 cymetidine ; receptors oppositely influence on IgE response in MNC cultures of ragweed sensitive patients and patients with lymphoand erythroproliferative diseases. The study of several imidazole and non-imidazole H3 H4 antagonists FUB 181, FUB 649, FUB 372, Imoproxifan-IMP and Ciproxifan -CF ; showed that IgE synthesis highly depends on the potency and structural differences of investigated H3 H4 antagonists. IgE regulation induced by histamine is closely related to well-known IgE-regulatory cytokine mechanisms. IgE synthesis modulated by histamine and several histamine receptor antagonists H1, H2 and H3 4 ; is highly dependent on the IL4, as well as IFH and IL13 production. Underlying mechanisms of IgE regulation modulated by histamine and its antagonists may be different in atopy and bone marrow alterations. Acknowledgement: Many thanks to prof. Walter Schunack from Berlin Frie University for providing us specific histamine receptor antagonists. 159 Antibody responses to minor allergen Bet v 2 during allergen specific immunotherapy in birch pollen allergic patients Larsen JN, Bdtger U * , Poulsen LK * , Ferreras M and Svenson M * . ALK-Abell, Hrsholm, Denmark. * National University Hospital, Copenhagen, Denmark. Background: Allergen specific immunotherapy SIT ; induces small changes in the level of specific IgE but most pronounced is a quantitative increase in allergen specific IgG. The effect on antibodies to minor as compared to major allergens is not clear. In this study antibodies towards Bet v 1 and Bet v 2 of Betula verrucosa were investigated in sera of SIT treated patients. Methods: Specific antibodies were assayed by the binding of 125I labelled purified natural Bet v 2 and recombinant Bet v 1.2801. Specific IgE was assayed following binding to anti-IgE monoclonal antibody coupled to paramagnetic beads. IgE depleted serum was tested for specific IgG and following incubation with the labelled allergen, free and bound allergen were separated by protein G affinity chromatography. Sera were tested in immunoblotting with or without absorption using 1 mg birch pollen extract. Results: All sera n 50 ; were positive for IgG and IgE against Bet v 1 before and after SIT. The relative binding activities of IgG compared to IgE were up to 30 times higher after SIT. In contrast, 22% of nontreated patients were positive for IgE anti-Bet v 2 and 48% for IgG anti-Bet v 2. At 1.5 years of SIT, the prevalence of IgG- and IgE-antiBet v 2 was unchanged, however, after 5 years of treatment, the prevalence of IgG anti-Bet v 2 was 91% but the prevalence of IgE anti-Bet v 2 was unchanged when analysed by quantitative immunoassay. Contrary to this observation, 3 sera became IgE anti Bet v 2 positive after 5 years of treatment when measured by immunoblotting. Conclusion: The dominant binding activity against Bet v 1 and Bet v 2 in sera from birch pollen allergic patients both before and after SIT resides in the IgG fraction. Prolonged SIT treatment induced IgG against minor allergens in most individuals. New IgE reactivities to Bet v 2 were observed after SIT in 3 patients by immunoblotting, however, this result was not confirmed by quantitative immunoassay and may possibly indicate differences in assay sensitivity with respect to denaturation insensitive epitopes.

BY PATRICK H. HIGGINS OF FOX ROTHSCHILD LLP PHIGGINS FOXROTHSCHILD the case of Schering v. Geneva wherein the court held that a patent claim which structurally described a metabolite of loratadine CLARITIN ; was inherently anticipated and hence invalid. 339 F.3d 1373 Fed. Cir. 2003 ; . The metabolite, descarboethoxyloratadine, is formed in the patient's body upon ingestion of loratadine. Since the claim would theoretically have precluded, for example, the prior administration of loratadine, the subject matter of the claim was found to be anticipated, i.e., "that which would literally infringe if later in time anticipates if earlier, " Schering citing BristolMyers Squibb Co. v. Ben Venue Labs., Inc., 246 F.3d 1368, 1378 Fed. Cir. 2001 ; . The risk is always present, however, that a blockbuster active pharmaceutical ingredient now claimed structurally, for example, may later be found to have existed earlier, or to exist naturally. A variety of diverse claims, nevertheless, can usually be drafted by an experienced practitioner to define compositions of next generation therapeutics, for example, to preserve market exclusivity even if the active entity, unbeknownst to the public or the inventor at the time of the invention, previously existed. As is necessary in the field of biochemistry, for instance, valid claims drawn to recently discovered natural compounds must define the subject matter in a manner that does not encompass the compounds as they have previously existed. Hence distinguishing terms such as "isolated", "purified", and or "comprising . in a pharmaceuticaly-acceptable carrier", as well as carefully composed product-by-process claims, in many cases provide valuable protection, yet obviate legal anticipation. The harsh reality is, however, that the Federal Circuit has again dealt the conseINTELLECTUAL PROPERTY TODAY JULY, 2005.
