Quetiapine belongs to a class of medications known as antipsychotics.

Antipsychotic agents are the principal class of drugs used for the management of all phases of schizophrenia.

Either immediate-release or extended-release tablets may be given; dosage titrated upward over 4 days. Generally, in maintenance phase, patients continue to receive same dosage on which they were stabilized.

The norepinephrine reuptake inhibition by norquetiapine has been suggested as a possible mechanism. Quetiapine antihistaminic effect has been reported to indirectly down regulate endogenous cytokines such as interleukine 1b and interleukine-6 and thus can partly explain quetiapine XR effect on bipolar depression and mixed phases. Quetiapine XR is well absorbed. Plasma concentration of quetiapine and norquetiapine are proportionate to the total daily dose.

Peak plasma concentration of quetiapine XR is often reached in 6 hours, with a mean terminal half-life of 7 hours. Absorption of quetiapine XR is highly affected by food intake. Steady state concentrations are expected within 2 days of dosing. Quetiapine XR is metabolized by the liver. The primary pathways are via sulfoxidation and oxidation. In vitro studies report involvement of the cytochrome P 3A4 isoenzyme. Dosage adjustments are recommended for patients with hepatic insufficiency.

Accordingly, medication dosage adjustment is highly recommended in this subpopulation. Figueroa and colleagues 18 compared pharmacokinetic profiles of quetiapine XR and quetiapine immediate release IR in patients with schizophrenia, and schizoaffective and bipolar disorder. C amx was achieved in 5 hours with quetiapine XR compared to 2 hours with quetiapine IR.

For example, ketoconazole slows quetiapine metabolism and thus increase its plasma concentration while phenytoin, carbamazepine and thioridazine lower it. As monotherapy, the FDA-approved quetiapine XR for the treatment of acute depressive episodes of bipolar disorder and acute manic or mixed episodes in bipolar I disorder based on two placebo-control trials see Table 1.

The FDA has also approved it as adjunct therapy with lithium and divalproex for the treatment of acute manic or mixed episodes as well as maintenance of bipolar I disorder, though this latter approval appears to be based on extrapolated data from quetiapine IR studies. All subjects were hospitalized for at least 4 days at the beginning of the study. The target flexible daily dose ranged from to mg. The primary outcome measure was change of YMRS total score after 3 weeks of randomization.

Among subjects on quetiapine XR, Two hundred and eighty subjects were recruited in this study. Subjects were randomized to either placebo or quetiapine XR with the later being progressively tapered to a total of mg daily by day 4 of the study. The separation between the two arms was evident as early as week one of randomization. Similarly, more subjects on quetiapine XR achieved remission than placebo Finally, Discontinuation rates were comparable to placebo though nearly a third of subjects receiving active medication withdrew from both studies.

During the 8-week acute depression study, the most commonly reported side effects were dry mouth There was no reported incidence of mania or hypomania reported in the acute depression study. The use of quetiapine XR in bipolar disorder has been associated with extrapyramidal side effects. In the 3-week acute mania study, EPS, ie, akathesia, dystonia, hypertonia, tremors and extrapyramidal disorder, were reported in 4. In a 3-week study of quetiapine XR in the treatment of bipolar mania, weight gain was noted to be relatively modest.

In the 8-week acute bipolar depression study, the mean average weight gain for quetiapine was 1.


For Schizoaffective Disorder Hello, I have been taking seroquel XR for just over a year now, started with 25mgs dose, now up to mgs dose. I found that my thoughts are controllable, relatively a good sleeping aid. Just be careful not to eat after an hour or so of taking certain brands of this medication.

Diuretics may also increase plasma lipid levels and cause glucose intolerance and insulin resistance, so they have to be used with caution in individuals with hyperlipidaemia andor diabetes. In addition, most diuretics produce an increase in plasma uric acid levels, which may lead to gout. ACE inhibitors are used to treat cardiac failure and hypertension. Inhibition of ACE prevents formation of angiotensin II, which is a powerful vasoconstrictor (see Figure resistance and therefore reduction in blood pressure. Reduction in blood pressure also improves cardiac output.

The fungal cell membrane contains a sterol called ergosterolwhich keeps the membrane stable. In human cell membranes, the sterol is cholesterol. This difference in cell membrane structure allows some selective toxicity of antifungal drugs and most antifungal drugs work by interfering with ergosterol production. Others prevent division of fungal cells.
