Arsenic Overview
Arsenic is a trace element naturally present in the diet, with organic forms being generally non-toxic in low amounts, while inorganic forms can be harmful. It is found in foods such as seafood, poultry, grains (especially rice), bread, cereal products, mushrooms, and dairy. The estimated daily intake of organic arsenic is 12-50 mcg, with a suggested requirement of 12-25 mcg daily, while inorganic arsenic intake is estimated at 3.5-10 mcg daily. Arsenic plays a potential role in metabolism, the recycling of methionine, taurine function, and the regulation of gene expression in the body. In traditional Chinese medicine, arsenic has been used to treat various inflammatory disorders, but it is generally only found in homeopathic preparations.
Quetiapine Overview
-
Quetiapine tablets and extended-release (long-acting) tablets are used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions). Quetiapine tablets and extended-release tablets are also used alone or with other medications to treat episodes of mania (frenzied, abnormally excited or irritated mood) or depression in patients with bipolar disorder (manic depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods). In addition, quetiapine tablets and extended-release tablets are used with other medications to prevent episodes of mania or depression in patients with bipolar disorder. Quetiapine extended-release tablets are also used along with other medications to treat depression. Quetiapine tablets may be used as part of a treatment program to treat bipolar disorder and schizophrenia in children and teenagers. Quetiapine is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.
