Mirtazapine is known to decrease sleep latency, promoting sleep efficiency and increasing the total amount of sleeping time in patients suffering from both depression and insomnia.

Maprotiline is more toxic than the other tetracyclic drugs Mianserin and Mirtazapine.

Mirtazapine ( Remeron, Avanza, Zispin ) is a noradrenergic and specific serotonergic antidepressant ( NaSSA ) which was introduced by Organon International in the United States in 1990 and is used primarily in the treatment of depression.

Mirtazapine is not considered to have a risk of many of the side effects often associated with other antidepressants like the SSRIs, and may actually improve certain ones when taken in conjunction with them.

Mirtazapine is also believed to be capable of this, and for this reason in the United States and certain other countries it carries a black box label warning of these potential effects.

Mirtazapine is considered to be relatively safe in the event of an overdose.

Mirtazapine is an antagonist / inverse agonist at the following receptors:

Mirtazapine is a very strong H < sub > 1 </ sub > receptor inverse agonist and as a result, it can cause powerful sedative and hypnotic effects.

Mirtazapine is typically prescribed in doses ranging from 15 mg to 45 mg.

Mirtazapine in combination with an SSRI, SNRI, or TCA as an augmentation strategy is considered to be relatively safe and is often employed therapeutically, with a combination of venlafaxine and mirtazapine sometimes referred to as " California rocket fuel ".

** Mirtazapine ( Remeron ), an antidepressant that also has antiemetic effects.

Mirtazapine and other antidepressants may cause a withdrawal syndrome upon discontinuation.

Mirtazapine may be used as an inexpensive antiemetic alternative to ondansetron.

Mirtazapine, a different type of antidepressant, also has antipruritic effects due to its strong antagonism of the H < sub > 1 </ sub > receptor.

** TCAs ( e. g. Imipramine, Mirtazapine ) and

An additional requirement is that the system not be racemic: a mixture of right-and left-handed molecules will cancel the chiral effect.

The racemic hydrochloride is the only form available in most countries, such as the Netherlands, Belgium, France and in the United States, as of March 2008.

These are more potent opioid agonists compared to racemic methadone because the dextrorotary form ( d-methadone ) is not an opioid agonist ( it is an NMDA antagonist ), therefore by using only the laevorotary form instead of the racemate the opioid agonist potency is doubled.

Covidien ( formerly Mallinckrodt ), is the major racemic methadone producer and sells bulk methadone to producers of generic preparations and distributes its own product in the form of tablets, dispersible tablets and oral concentrate under the brand name Methadose in the United States.

The most common route of administration at a methadone clinic is in a racemic oral solution, though in Germany, only the R enantiomer ( the L optical isomer ) has traditionally been used, as it is responsible for most of the desired opioid effects.

There are two methadone isomers that form the racemic mixture which is more common as it is cheaper to produce.

The laevorotary isomer, which is isolated by several recrystalisations from racemic methadone, is more expensive to produce than the racemate.

It is more potent at the opioid receptor than the racemic mixture and is marketed especially in continental Europe as an analgesic under the trade names Levo-Polamidone, Polamidone, Heptanone, Heptadone, Heptadon and others.

If the diad consists of units oriented in opposition, the diad is called a racemo diad as in a racemic compound.

Thalidomide is racemic – it contains both left-and right-handed isomers in equal amounts.

A meta-analysis of studies using Vitamin E, sorting results by the form ( racemic vs non-racemic ) used, is necessary.

Sarin is a chiral molecule ( typically racemic ), with four substituents attached to the tetrahedral phosphorus center.

In chemistry, a racemic mixture, or racemate (), is one that has equal amounts of left-and right-handed enantiomers of a chiral molecule.

A racemic mixture is denoted by the prefix (±)- or dl-( for sugars the prefix-may be used ), indicating an equal ( 1: 1 ) mixture of dextro and levo isomers.

The melting point of the racemic conglomerate is always lower than that of the pure enantiomer.

: In contrast to the racemic compound or conglomerate, there is no big difference in affinity between the same and opposite enantiomers.

This fact also leads to the question of how biological homochirality evolved on what is presumed to be a racemic primordial earth.

Atropine is a racemic mixture of d-hyoscyamine and l-hyoscyamine, with most of its physiological effects due to l-hyoscyamine.

Lignin is a cross-linked racemic macromolecule with molecular masses in excess of 10, 000 u.

On this, she builds an `` egg compartment '' or `` egg cell '' which is filled with that famous pollen-and-nectar mixture called beebread.

Basically, this means that simpler processing equipment ( the mixture has good flowing characteristics ) and less external heat ( the foaming reaction is exothermic and develops internal heat ) are required in one-shot foaming, although, at the same time, the problems of controlling the conditions of one-shot foaming are critical ones.

In a typical application -- the making of rigid urethane foam sandwich panels -- an amount of foam mixture calculated to expand 10 to 20% more than the volume of the panel is poured into the panel void and the top of the panel is locked in place by a jig.

The bread baked from this mixture is light in color and fragrant in aroma.

For, in the process of decanting, the bottle is only tilted once instead of several or more times at the table: hence, a minimum of the undesirable mixture of wine and dregs.

It is an over-all impression Mr. Sansom strives for, an impression compounded of visual details, of a savory mixture of smells, of much loving attention to architecture and scenery, of lights and shadows, of intangibles of atmosphere and of echoes of the past.

Hence it is the atomic number alone that determines the chemical properties of an element ; and it is for this reason that an element can be defined as consisting of any mixture of atoms with a given atomic number.

The mixture is roughly half sand ( 50 %), one-third clay ( 35 %), and one-sixth straw ( 15 %) by weight.

The mixture is molded by the frame, and then the frame is removed quickly.

The same mixture to make bricks, without the straw, is used for mortar and often for plaster on interior and exterior walls.

Depending on the form into which the mixture is pressed, adobe can encompass nearly any shape or size, provided drying time is even and the mixture includes reinforcement for larger bricks.

An alloy is a mixture or metallic solid solution composed of two or more elements.

Unlike pure metals, most alloys do not have a single melting point, but a melting range in which the material is a mixture of solid and liquid phases.

However, for most alloys there is a particular proportion of constituents ( in rare cases two )— the eutectic mixture — which gives the alloy a unique melting point.

The term alloy is used to describe a mixture of atoms in which the primary constituent is a metal.

If there is a mixture of only two types of atoms, not counting impurities, such as a copper-nickel alloy, then it is called a binary alloy.

If there are three types of atoms forming the mixture, such as iron, nickel and chromium, then it is called a ternary alloy.
