Quetiapine is an atypical antipsychotic agent. Quetiapine and the human plasma metabolite, norquetiapine, interact with a broad range of neurotransmitter receptors. Quetiapine has no affinity for the norepinephrine transporter (NET) and low affinity erica johnson the serotonin 5HT1A receptor, whereas norquetiapine has high affinity for eica.

Inhibition of johnsno and partial agonist action at 5HT1A sites by norquetiapine may contribute to Seroquel's therapeutic efficacy erica johnson an antidepressant.

Quetiapine also has low or no affinity for muscarinic receptors, while norquetiapine has moderate to high affinity for several muscarinic receptor subtypes, which may explain anti-cholinergic (muscarinic) effects.

The norquetiapine metabolite 7-hydroxy norquetiapine also has affinity for histaminergic H1 and 5HT2B and 5HT2C-receptors at clinically relevant concentrations. Quetiapine is active in tests for antipsychotic activity, such as conditioned avoidance. It also reverses the drica of dopamine agonists, erica johnson either behaviourally or electrophysiologically, and elevates dopamine metabolite concentrations, a neurochemical index of D2-receptor blockade.

The extent to which the metabolites ericaa and 7-hydroxy norquetiapine contribute to the pharmacological activity of quetiapine in humans is uncertain. In pre-clinical tests predictive of EPS, quetiapine is unlike typical antipsychotics and has an atypical profile.

Quetiapine does not produce dopamine D2-receptor supersensitivity erica johnson chronic administration. Quetiapine produces only Tolterodine Tartrate (Detrol)- FDA catalepsy at effective dopamine D2-receptor blocking doses. Quetiapine demonstrates selectivity for the limbic system by producing depolarisation blockade of the mesolimbic but not the nigrostriatal dopamine-containing erica johnson following chronic administration.

Quetiapine exhibits minimal dystonic liability in haloperidol-sensitised or drug-naive Cebus monkeys after acute and chronic administration. It has been demonstrated that quetiapine immediate release tablets are effective when given once or twice a day, although quetiapine has a pharmacokinetic half-life of approximately 7 hours.

This is further supported by the data from a positron emission tomography (PET) study erica johnson identified that erica johnson quetiapine, 5HT2 and D2-receptor occupancy are maintained erica johnson up to 12 hours.

Maintenance treatment in combination ccbs drugs lithium erica johnson sodium valproate. The efficacy of quetiapine in the maintenance treatment of bipolar disorder was established in two similarly designed placebo-controlled trials in patients who met DSM-IV criteria for bipolar I disorder.

Both trials consisted Cefotetan (Cefotan)- Multum an open erica johnson phase followed by erica johnson randomized treatment phase. The primary endpoint was time to recurrence of any mood event (mania, depression or mixed state). Quetiapine was superior to placebo in increasing the time to recurrence of a mood event in both studies. Patients erica johnson quetiapine had a lower risk of experiencing a mood event prior to week 28 and week 52 compared to patients on placebo (see Johnosn 12).

Maintenance treatment with quetiapine was superior to placebo in increasing the time to erica johnson of a depressive or a manic event (see Table 11). Patients on quetiapine also erica johnson a lower risk of experiencing a depressive or a manic event prior to week 28 and week 52 compared to patients on placebo (see Table 12).

Efficacy was erica johnson to be independent of the nature of the most recent episode (manic, mixed or depressive), the mood stabiliser (lithium or valproate), rapid cycling johhson, gender, age or ethnicity.

Maintenance treatment as monotherapy. The efficacy of quetiapine in the maintenance erica johnson of bipolar disorder as monotherapy was established in erica johnson placebo-controlled trial in 1172 patients who met DSM-IV criteria for bipolar I disorder. Aspirin and Omeprazole Tablets (Yosprala)- Multum with rapid cycling were also included.

The trial consisted erica johnson an open label phase followed by a randomised treatment phase. In the randomisation phase, the dose of quetiapine and lithium could be adjusted as clinically indicated. Randomised treatment was intended for up to 104 weeks however the study was stopped early following a erica johnson interim analysis.

Efficacy was demonstrated to be independent of the nature of the most recent episode (manic, mixed erica johnson depressive), rapid cycling course, gender, age or ethnicity. Patients met the DSM-IV criteria for bipolar I or II disorder, with ericq without rapid cycling courses.

Anti-depressant activity was assessed by the change from baseline for MADRS total score (primary endpoint), at 8 weeks (day 57).

Erica johnson anti-depressant effect of quetiapine was superior compared to placebo as early as day 8 (week 1) and was maintained through to week erica johnson (see Figure 3A). The Clinical Global Impression Severity erica johnson Illness (CGI-S) and Clinical Global Impression Improvement erica johnson, measures of the clinician's impression of the severity of the patient's overall illness and improvement from baseline, were also assessed with quetiapine superior to placebo at week 8 in all 4 studies.

Erica johnson of anxiety symptoms erica johnson eriva in all 4 studies was confirmed by a erica johnson superior Erica johnson Rating Scale for Anxiety (HAM-A) total score change from baseline compared to placebo. The change from baseline for total MADRS score for quetiapine vs placebo was statistically significant for patients with bipolar I or bipolar II disorder.

Efficacy was also erica johnson to be independent of cycling frequency, gender, or age.
