Monitoring the manufacturing and quality of medicines: a fundamental task of pharmacovigilance.

Unlabelled: The collection and assessment of individual case safety reports (ICSRs) is important to detect unknown adverse drug reactions particularly in the first decade after approval of new chemical entities. However, regulations require that these activities are routinely undertaken for all medicinal products, including older medicines such as generic medicinal products with a well-established safety profile. For the latter, the risk management plans no longer contain important risks, considered important safety concerns, on the basis that routine pharmacovigilance activity would not allow their further characterisation.

Evaluation of quantitative signal detection in EudraVigilance for orphan drugs: possible risk of false negatives.

Different strategies have been studied to allow a better characterization of the safety profile of orphan drugs soon after their approval. At the end of the development phases only few data are available because of the small number of subjects exposed to an orphan medicine for the treatment of rare or ultra-rare conditions. As a consequence, the evaluation of the safety profile is limited at the time of the first approval.

Pharmacovigilance of medicines for rare and ultrarare diseases.

The assessment of the safety of medicines for rare diseases during the development phase is often limited by the few data available from small numbers of patients. This also applies to a lesser extent during the postmarketing phase of the lifecycle of a medicine. By using all available sources of data for rare diseases drugs, and by carefully assessing these data, the most informed safety profile can be obtained.

Drug safety evaluation of defibrotide.

Introduction: Hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), is a potentially life-threatening complication of chemotherapeutic conditioning used in preparation for hematopoietic stem-cell transplantation (SCT). Defibrotide (DF) has been shown in Phase II and III trials to improve complete response in patients with severe VOD (sVOD). None of the articles, to date, provide a comprehensive review of the safety of DF in VOD and/or a range of other conditions.

Dopamine is involved in the antidepressant-like effect of allopregnanolone in the forced swimming test in female rats.

Evidence from both animal and human studies suggests a role for dopamine in the therapeutic effect of antidepressant drugs. Consistently, dopamine receptor antagonists antagonize the effect of antidepressant drugs in different experimental models of depression. Neurosteroids, and in particular allopregnanolone, seem to be involved both in the pathophysiology of depression and in the mechanism of action of antidepressant drugs, and their role seems to be particularly important in the understanding of mood disturbances related to the different phases of the reproductive life in women.
