Tolerability and safety are important considerations in optimising pharmacotherapy for bipolar disorder. This paper reviews the tolerability and safety of lamotrigine, an anticonvulsant recommended in the 2002 American Psychiatric Association guidelines as a first-line treatment for acute depression in bipolar disorder and one of several options for maintenance therapy. This paper reviews the tolerability and safety of lamotrigine using data available from a large programme of eight placebo-controlled clinical trials of lamotrigine enrolling a total of nearly 1800 patients with bipolar disorder. This review is the first to collate all the safety information from these clinical trials, including data from four unpublished studies. The results these trials in which 827 patients with bipolar disorder were given lamotrigine as monotherapy or adjunctive therapy for up to 18 months for a total of 280 patient-years of exposure demonstrated that lamotrigine is well-tolerated with an adverse-event profile generally comparable with that of placebo. The most common adverse event with lamotrigine was headache. Lamotrigine did not appear to destabilise mood and was not associated with sexual adverse effects, weight gain, or withdrawal symptoms. Few patients experienced serious adverse events with lamotrigine, and the incidence of withdrawals because of adverse events was low. Serious rash occurred rarely (0.1% incidence) in the clinical development programme including both controlled and uncontrolled clinical trials. These findings - considered in the context of data showing lamotrigine to be effective for bipolar depression - establish lamotrigine as a well-tolerated addition to the psychotropic armamentarium.

INTRODUCTION: The incidence of bipolar disorder in the general population has been estimated at approximately 5%. The purpose of this study was to establish a relationship between patients' complaints on arrival to a primary care clinic and their subsequent scores on the Hirschfeld Mood Disorder Questionnaire (MDQ). METHOD: After reviewing data obtained from 178 consecutive patients, 171 were found adequate for study inclusion. The inclusion criteria for this study were presentation to a family practice office for care regardless of complaint and age of 18 years or older. Study participants were asked to complete a historical/demographic questionnaire, which gathered data on primary and secondary complaints and medication history, and the MDQ. RESULTS: Thirty patients (17.5%) tested positive on the MDQ for bipolar symptoms; all were aged 65 years or under. Of those who tested positive, 20% (N = 6) presented with a primary complaint of anxiety or depression. Somatic primary complaints of pain and headache carried a high likelihood of secondary complaints of anxiety or depression. CONCLUSION: Patients with complicated or multiple somatic complaints in primary care may also have concomitant undiagnosed bipolar disorder. Clinicians should use a high index of suspicion for the diagnosis of bipolar disorder when treating patients with these assessment characteristics. Further research is necessary to determine if these trends are applicable in a larger population.

Lamotrigine is a novel anticonvulsant agent that has recently been introduced as a long-term treatment in bipolar disorder. Its role in the treatment of epilepsy is based on its actions to decrease ion channel conductance and antagonise glutamatergic function. Therefore, it has a mode of action unlike other agents used on a long-term basis in mood disorders. The evidence for efficacy is stronger for the prevention of depressive, rather than manic, episodes. The pivotal trials are in bipolar I disorder, but there is interest in its actions in patients with bipolar II and spectrum conditions. Its efficacy in other psychiatric conditions remains to be properly established. It is well tolerated and, with careful prescribing, the incidence of rash occurs no more than with placebo; however this is still a concern. Although usually well tolerated, headache, insomnia and drowsiness are probably the most common side effects.

Epilepsy and bipolar disorder are commonly treated by combination drug therapy, such as lamotrigine and oxcarbazepine. To ensure the safety of this combination, information on pharmacokinetics and tolerability must be available. The objective of study was to evaluate the pharmacokinetics and tolerability of coadministered lamotrigine and oxcarbazepine in healthy subjects. This randomized, single-blind, parallel-group study comprised three cohorts: lamotrigine (200 mg daily) plus oxcarbazepine (600 mg twice daily), lamotrigine (200 mg daily) plus placebo, and oxcarbazepine (600 mg twice daily) plus placebo. Serial blood samples were collected at steady state to determine serum concentrations of lamotrigine and plasma concentrations of oxcarbazepine and its active metabolite 10-monohydroxy metabolite (MHD). Pharmacokinetic parameters were determined by noncompartmental methods. Tolerability was monitored through adverse event reports, clinical laboratory results, vital signs, and electrocardiograms. A total of 47 male volunteers received study drugs. At steady state, lamotrigine AUC((0-24)) and C(max) were not significantly affected by oxcarbazepine co-therapy, nor were MHD AUC((0-12)) and C(max) significantly affected by lamotrigine co-therapy. The most common adverse events, headache, dizziness, nausea, and somnolence, occurred more frequently during lamotrigine and oxcarbazepine combination therapy than during the monotherapy. No significant changes in clinical laboratory parameters, vital signs, or electrocardiograms were reported. In conclusion, the combination of lamotrigine and oxcarbazepine does not require dose adjustments based on pharmacokinetic data. However, it is important to recognize that the combination therapy was associated with more frequent adverse events.

Migraine is a common chronic disorder that presents with recurrent attacks of headache and associated symptoms. Various somatic and psychiatric conditions have been reported as comorbid conditions with migraine. Among the psychiatric disorders that have been reported as comorbid with migraine are major depression, anxiety, panic disorder, and bipolar disorder. Recent studies discussing the comorbidity of headache and psychiatric disorders are reviewed here.

B.D. is a 48-year-old professional woman. She has been suffering for migraine since she was 28, but she did not have serious problems until last year, when headache episodes became more frequent and it was necessary an admission to emergency room. At the beginning, the events were about 6 per month, lasting from 2 to 4 days, beating and of high intensity together with nausea, vomit, photo and phonophobia and visual area. Looking at the anamnesis, we report a psychiatric treatment since about ten years, because of type II bipolar disorder. In spite of the psychopharmacological treatment, as the patient came in our Regional Headache Center, she talked about 7 events with aura (scintillating scotomas, emianopsia) per month, lasting 2-4 days with photo and phonophobia, nausea, crying crisis, anxiety. Although the neurological examination was normal, the sudden aggravation of pain symptomatology and the unresposiveness to usual painkillers, suggested a cerebral CT and CT-angiography. CT and CT-angiography discovered the presence of an aneurysm of the right middle cerebral artery (MCA) of 4 mm diameter, with parietal irregularities. The patient was operated to reduce the hemorrhagic risk, with a positive result. One year after the operation, the patient reports a decrease of headache events with a frequency of 2 per month, lasting only a few hours, which she can now solve with COXIB.

Carbamazepine (CBZ) has a long history of successful use in epilepsy and, therefore, has a safety profile that is well characterised. Additionally, an extended-release formulation of CBZ (CBZ-ERC; Equetro, Shire US) has recently been approved for use in bipolar disorder. The most frequent adverse events associated with CBZ are somnolence, fatigue, dizziness and headache. Rash and leukopoenia may occur in approximately 10% of patients, but are benign and transient in most cases. Rare serious adverse effects include agranulocytosis, aplastic anaemia, Stevens-Johnson syndrome and toxic epidermal necrolysis. Although changes in lipid profiles have been noted, hyperglycaemia does not occur with CBZ, and clinically significant weight gain is uncommon. Proper monitoring and careful titration of the extended-release formulation should allow for successful use of CBZ in psychiatric patients.

Migraine affects nearly 12% of the adult population in the United States and causes significant lost productivity and decrements in health-related quality of life. The burden of migraine and the challenge in managing it are increased by the comorbid psychiatric conditions that occur in association with it. Studies in both clinical and community-based settings have demonstrated an association between migraine and a number of specific psychiatric disorders. This review will focus on the relationships between migraine and depression, generalized anxiety disorder, panic disorder, and bipolar disorder. In large scale population-based studies, persons with migraine are from 2.2 to 4.0 times more likely to have depression. In longitudinal studies, the evidence supports a bidirectional relationship between migraine and depression, with each disorder increasing the risk of the other disorder. Migraine is also comorbid with generalized anxiety disorder (Odds Ratio [OR] 3.5 to 5.3), panic disorder (OR 3.7), and bipolar disorder (OR 2.9 to 7.3). A diagnosis of migraine should lead to a heightened level of diagnostic suspicion for these comorbid psychiatric disorders. Similarly, a diagnosis of one of these psychiatric disorders should increase vigilance for migraine. Treatment plans for migraine should be mindful of the comorbid conditions.

Since 2005, the chief residents of the University Outpatient Clinic of Lausanne have established a database of articles chosen from miscellaneous reviews and electronic journals and selected for their scientific value and practical usefulness. This first review is based on articles published in 2006 and covering five topics useful for the primary care physician: chronic daily headaches are frequent in women, isolated vertigo is only exceptionally a sign of stroke and a bipolar disorder must be investigated in case of depression. HIV testing in a medical setting is at present more satisfactory than rapid HIV testing at home and finally watchful waiting of inguinal hernia is possible in asymptomatic or pauci-symptomatic men.

Oxcarbazepine is an antiepileptic drug that has been approved by the US FDA and is indicated for use as monotherapy or adjunctive therapy in the treatment of partial seizures in adults and children aged over 4 years. The aim of this report is to investigate the results of clinical trials in order to ascertain the efficacy and safety of oxcarbazepine for use in bipolar disorder and schizoaffective disorder. Oxcarbazepine is a keto-congener of carbamazepine with fewer side effects and drug interactions. Orally administrated oxcarbazepine is rapidly and completely absorbed and has a half-life of 9 h. Currently, there is a lack of controlled clinical trials studying the use of oxcarbazepine. In light of controlled and open-label prospective studies, it may be useful for manic symptoms in the treatment of bipolar and schizoaffective patients. Case reports, retrospective and prospective studies suggest that oxcarbazepine might have prophylactic efficacy and long-term benefit for these patients. In addition, owing to its lower propensity for drug interactions and side effects, it may be useful in the treatment of refractory patients with bipolar and schizoaffective disorder. However, most of the trials have relevant methodological shortcomings. The side-effect profile of oxcarbazepine is similar to carbamazepine, but the severity of these effects appears to be slightly less. The symptoms that are most frequently associated with the use of oxcarbazepine are asthenia, headache, dizziness, somnolence, nausea, diplopia and skin rash. Isolated cases of hyponatremic coma have been reported, thus electrolyte abnormalities should be closely monitored. Oxcarbazepine is now a generic drug, but the metabolite licarbazepine and other related compounds, such as eslicarbazepine, are currently being studied under controlled conditions and might become useful therapies for bipolar and schizoaffective disorder in the future.
