Diário Oficial Da União
The ''Diário Oficial da União'' (literally ''Official Diary of the Union''), abbreviated DOU, is the government gazette, official gazette of the Federal Government of Brazil, Federal Government of Brazil. It is published since 1 October 1862 and was created via the Imperial Decree 1,177 of its 9 September as the ''Official Journal of the Empire of Brazil''. Its current name was adopted after Brazil became a federal republic, and the "Union" came into being as the legal personality of the new federal government. The official journal is published by the Imprensa Nacional, Brazilian National Press. Though the journal has been published since 1862, it had many predecessors, as follows: # Gazeta do Rio de Janeiro (10/9/1808 – 29.12.1821) # Gazeta do Rio (1/1/1822 – 31/12/1822) # Diário do Governo (2/1/1823 – 28/6/1833) # Diário Fluminense (21/5/1824 – 24/4/1831) # Correio Oficial (1/7/1833 – 30/6/1836) e (2/1/1830 – 30/12/1840) # Without proper journal (31/12/1840 – ...

Anticholinergic
Anticholinergics (anticholinergic agents) are substances that block the action of the acetylcholine (ACh) neurotransmitter at synapses in the central nervous system, central and peripheral nervous system. These agents inhibit the parasympathetic nervous system by selectively blocking the binding of ACh to its receptor in nerve cells. The nerve fibers of the parasympathetic system are responsible for the involuntary movement of Smooth muscle tissue, smooth muscles present in the gastrointestinal tract, urinary tract, lungs, sweat glands, and many other parts of the body. In broad terms, anticholinergics are divided into two categories in accordance with their specific targets in the central and peripheral nervous system and at the neuromuscular junction: antimuscarinic agents and antinicotinic agents (ganglionic blockers, neuromuscular blockers). The term "anticholinergic" is typically used to refer to antimuscarinics that competitively inhibit the binding of ACh to muscarinic a ...

Management Of Parkinson's Disease
In the management of Parkinson's disease, due to the chronic nature of Parkinson's disease (PD), a broad-based program is needed that includes patient and family education, support-group services, general wellness maintenance, exercise, and nutrition. At present, no cure for the disease is known, but medications or surgery can provide relief from the symptoms. While many medications treat Parkinson's, none actually reverses the effects of the disease. Furthermore, the gold-standard treatment varies with the disease state. People with Parkinson's, therefore, often must take a variety of medications to manage the disease's symptoms. Several medications currently in development seek to better address motor fluctuations and nonmotor symptoms of PD. However, none is yet on the market with specific approval to treat Parkinson's. Medication The main families of drugs useful for treating motor symptoms are levodopa, dopamine agonists, and MAO-B inhibitors. The most commonly used treatm ...

Dothiepin
Dosulepin, also known as dothiepin and sold under the brand name Prothiaden among others, is a tricyclic antidepressant (TCA) which is used in the treatment of depression. Dosulepin was once the most frequently prescribed antidepressant in the United Kingdom, but it is no longer widely used due to its relatively high toxicity in overdose without therapeutic advantages over other TCAs. It acts as a serotonin–norepinephrine reuptake inhibitor (SNRI) and also has other activities including antihistamine, antiadrenergic, antiserotonergic, anticholinergic, and sodium channel-blocking effects. Medical uses Dosulepin is used for the treatment of major depressive disorder. There is clear evidence of the efficacy of dosulepin in psychogenic facial pain, though the drug may be needed for up to a year. Contraindications Contraindications include: * Epilepsy as it can lower the seizure threshold * TCAs should not be used concomitantly or within 14 days of treatment with monoamine oxid ...

Muscarinic Antagonists
A muscarinic acetylcholine receptor antagonist, also simply known as a muscarinic antagonist or as an antimuscarinic agent, is a type of anticholinergic drug that blocks the activity of the muscarinic acetylcholine receptors (mAChRs). The muscarinic receptors are proteins involved in the transmission of signals through certain parts of the nervous system, and muscarinic receptor antagonists work to prevent this transmission from occurring. Notably, muscarinic antagonists reduce the activation of the parasympathetic nervous system. The normal function of the parasympathetic system is often summarised as "rest-and-digest", and includes slowing of the heart, an increased rate of digestion, narrowing of the airways, promotion of urination, and sexual arousal. Muscarinic antagonists counter this parasympathetic "rest-and-digest" response, and also work elsewhere in both the central and peripheral nervous systems. Drugs with muscarinic antagonist activity are widely used in medicine, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thioxanthenes
Thioxanthene is a chemical compound in which the oxygen atom in xanthene is replaced with a sulfur atom. It is also related to phenothiazine. Several of its derivatives are used as typical antipsychotics in the treatment of schizophrenia and other psychoses. Derivatives The derivatives of thioxanthene used clinically as antipsychotics include: * Chlorprothixene (Cloxan, Taractan, Truxal) * Clopenthixol (Sordinol) * Flupenthixol (Depixol, Fluanxol) * Thiothixene (Navane) * Zuclopenthixol (Cisordinol, Clopixol, Acuphase) The therapeutic efficacy of these drugs is related to their ability to antagonize the D2 receptors in the brain, though they have actions at other sites such as serotonin, adrenaline, and histamine receptors as well which mostly contribute to side effects. The thioxanthenes, as a class, are closely related chemically to the phenothiazines. The major structural difference is that the nitrogen at position 10 in the phenothiazines is replaced by a carbon atom w ...
