Lamotrigine
Description: Stimulated by sales of atypical antipsychotics for bipolar depression, and despite the launch of generic risperidone, the global bipolar disorder market will grow until 2011, when revenues will peak at $6.6 billion. The market will begin to decline thereafter owing to the launch of generic versions of the leading atypical antipsychotics, quetiapine, olanzapine, and ziprasidone from 2011 onwards. Scope of this title: - Analysis of patient potential, unmet needs and clinical trial design in bipolar disorder - Overview of drugs in pre-registration, Phase III, II and I; with analysis of key companies involved in the market - Detailed profiles of key compounds in development for use in bipolar disorder, with forecasts of drug revenues to 2015 - Discussion of indication expansion strategies and insight from key industry opinion leaders Highlights of this title: - AstraZeneca will be the first company to bring an atypical antipsychotic to the bipolar depression market as a monotherapy, following demonstration of efficacy with quetiapine. Pfizer will maintain a strong schizophrenia franchise by releasing asenapine to buffer the loss in revenue due to genericization of ziprasidone. - Solvay Wyeth Lundbecks bifeprunox will be the leading market entrant in terms of bipolar disorder specific sales revenue. These companies appear to be seeking initial license for bifeprunox in the bipolar depression indication, a tactic that will both increase the commercial viability of the drug and save time money. - Despite the commercial success of Lamictal lamotrigine ; and Depakote valproate ; , the latestage bipolar disorder pipeline only includes one anticonvulsant class molecule, Novartis licarbazepine. Reasons to order your copy: - Understand unmet needs in the bipolar disorder market based on key opinion leader comments - Benchmark key late-stage bipolar disorder compounds against current market leaders - Assess the global US, Japan, five major EU ; sales forecasts of late-stage pipeline drugs; and examine their clinical and commercial potential.
Results typical and atypical antipsychotic drugs have a complex pharmacology initial screening assays were performed with a large number of typical and atypical antipsychotic drugs, for instance, lamotrigine memory.
Synopsis Cephalon Inc has announced results from three multi-centre studies which show that a new once-daily formulation of modafinil significantly improve symptoms of ADHD in children and adolescents. These three 9-week, double-blind, placebo-controlled studies involved 600 children and adolescents aged 6-17 years, who were randomised to placebo or the new formulations of modafinil. The primary endpoint was the teacher-completed school version of the ADHD Rating Scale IV. All of the modafinil treated groups showed a highly statistically significant improvement on the primary endpoint compared to placebo p 0.0001 ; . The most common side effects observed in the modafinil groups included insomnia, headache and loss of appetite. The complete Phase III study data are due to be presented at major medical meetings over the next 12 months. The company plans to accelerate the filing of its application with the FDA from the first quarter of 2005 to the fourth quarter of 2004. Modafinil ProvigilTM ; is currently available as 100 and 200mg tablets and is indicated for the treatment of excessive sleepiness associated with narcolepsy, obstructive sleep apnoea and shift work sleep disorder.

Lamotrigine is not used as a replacement drug for children under 1 for bipolar disorder due to the lack of clinical studies, lamotrigine is not recommended for treating bipolar disorder in children under 18 years old.
The Princess Royal Maternity PRM ; hospital comprises five clinical floors and has been planned to accommodate over 6000 deliveries annually. The PRM is a consultant-led unit but has a friendly atmosphere and informal relationships between medical grades, which encourages input by junior staff in management decisions. However, midwives have less impact on departmental decisions. The PRM provides 110 beds including 8 for special needs patients. Smaller ward units with many single rooms, with personal toilet and bathing facilities, are also available. Birthing facilities include a delivery suite with 234.
In levonorgestrel clearance, and the changes in serum FSH and LH, on ovarian ovulatory activity is unknown see section 4.4 ; . The effects of doses of lamotrigine other than 300 mg day have not been studied and studies with other female hormonal preparations have not been conducted. Effect of other active substances on the pharmacokinetics of lamotrigine Antiepileptic agents which induce drug-metabolising enzymes such as phenytoin, carbamazepine, phenobarbital and primidone ; enhance the metabolism of lamotrigine and may increase dose requirements see section 4.2 ; . Half-life of lamotrigine is shortened to approximately 14 hours, in children below 12 years: approximately 7 hours. Valproate reduces the metabolism of lamotrigine and increases the mean half-life of lamotrigine nearly 2 fold see sections 4.2 and 4.4 ; . Half-life of lamotrigine is extented to approx. 70 hours, in children below 12 years: 45-55 hours.

Lamotrigine Of all available so-called mood stabilisers, lamotrigine is supported by the largest trial suggesting acute antidepressant efficacy. Strictly speaking, however, it failed to show significance for the primary outcome variable, namely the Hamilton Depression Scale, against placebo Calabrese et al 1999a ; . However, other ratings CGI ; were significantly in favour of lamotrigine. Unfortunately, at present there is no controlled trial published comparing lamotrigine with a standard antidepressant. Thus, together with the considerable number of open trials of uncertain validity, we would grade the evidence for antidepressant efficacy of lamotrigine at Level B. Tolerability As always, tolerability and side effects pose distinct advantages and disadvantages for individual drugs in individual patients. Compared with lithium, valproate and carbamazepine, it appears that patients are most satisfied with lamotrigine as far as efficacy and side effects are concerned J. Goldberg, data presented at the APA 2000 ; . However, especially the risk of allergic reactions with lamotrigine and also carbamazepine should not be underestimated. Switch risk Many physicians, especially in North America, appear more concerned about the risk of a switch into mania than about maximal efficacy in treating depression. On the one hand, manic episodes can be devastating for the patient and his occupational and family life. On the other hand, insufficient treatment of depression may severely reduce the patients' functional capacities and put them at an increased risk of suicide. As far as the switch rates reported with mood stabiliser monotherapy are concerned, they appear to be between 0 and 5 %, with lithium probably being the most effective in switch prevention Calabrese et al 1999b ; . The natural risk of a switch into mania during recovery from a bipolar depression has been estimated to be between 4 and 8 % Angst 1985; Bunney et al 1972 ; . Antidepressant monotherapy without an accompanying mood stabiliser, however, may increase this switch risk significantly Lewis and Winokur 1982; Wehr and Goodwin 1987 ; . However, the highest reported switch rates up to 70 % ; originate from a time when treatment with a TCA or irreversible MAOinhibitor were the only options. When new antidepressants are used, especially SSRIs, the switch risk may not be much different from the natural switch risk Peet 1994 ; , and can be sufficiently controlled with the addition of a mood stabiliser Boerlin et al 1998 ; , although a mood stabiliser cannot totally eliminate it Bottlender et al 1998; Quitkin et al 1981 ; . Switch rates reported for SSRIs administered in combination with a mood stabiliser are of the same order as the switch rate for mood stabiliser.

Although chemicals can be used to prevent and cure diseases, a good health management system is the best tool for disease prevention. Several measures concerning disease control should be considered in advance. The use of vaccines Song et al. 1980, Lin et al. 1982, Chen and Kou 1985 ; , immunostimulants, biological control Wu and Chao 1984 ; , or probiotics containing beneficial microorganisms has the potential to replace chemotherapy. To date, however, the efficacy of these measures is not yet encouraging.

5. The patients' views and preferences have been sought. Information about patients' experiences and expectations of health care should inform the development of clinical guidelines. There are various methods for ensuring that patients' perspectives inform guideline Development. For example, the development group could involve patients' representatives, information could be obtained from patient interviews, literature reviews of patients' experiences could be considered by the group. There should be evidence that this process has taken place, for instance, lamotgigine for bipolar disorder.
