For all drugs and dosages, the most popular Roscovitine manufacturer choice was increasing the dosage, followed by augmenting with lithium or another antidepressant, or changing to a different drug. Conclusion The question of nonresponse is clearly important and has to be considered within the recent evolution of psychiatric classification and treatment. First, traditional classifications are being increasingly criticized for failing to define homogeneous patient groups, who might respond in a predictable

way to a specific treatment. The fact that psychiatric classification is in a state of flux is exemplified by the ongoing revision process of Inhibitors,research,lifescience,medical DSM. Research in neuroscience is expected to play a major part in the preparation of DSM-V.35 The necessity for a classification that could better guide treatment choice is manifest. Second, psychopharmacology is changing. Inhibitors,research,lifescience,medical There is an evolution from drugs directed at symptoms toward drugs directed at syndromes and the pathophysiology Inhibitors,research,lifescience,medical of psychiatric disorders. New drugs

are being evaluated for their overall efficacy, eg, for their efficacy on syndromes and cognition, rather than on a single symptom. More is required today from treatment methods. Patients and clinicians are no longer satisfied with a mere reduction in symptoms. Etiological treatment is an ideal; in some cases, this ideal might become reality. The notion

of nonresponse is best understood in its historical dimension. Our opinion is still influenced by traditional thought patterns. Inhibitors,research,lifescience,medical However, nonresponse is likely to be envisaged quite differently in the near future. A few tasks will remain crucial, such as the definition of criteria for treatment response, and the delineation of factors that exert a negative influence on drug efficacy. The problem of nonresponse Inhibitors,research,lifescience,medical exists in all domains of medicine. It is crucial for patients and their families to understand that the physicians did ail they could and offered the best available treatments to patients who remained nonresponders.
One of the elusive goals of pharmacotherapy is the ability to identify the relevant characteristics of a. patient with a particular disorder in such a way as to permit, selection of the best pharmacological others agent: the medication with the greatest, likelihood of effectiveness and the least, likelihood of adverse or undesirable effects. Despite the considerable number of treatments in our psychotherapeutic armamentarium, any individual treatment applied to a group of persons with a given disorder will leave an un acceptably high percentage nonresponsive, again consequent, to lack of efficacy or inability to tolerate the treatment. To increase the odds of therapeutic success, it.
