Beim Schwartz-Bartter-Syndrom (Syn.: "Syndrom der inadäquaten ADH-Sekretion" (SIADH)) besteht eine, in Bezug auf die Blutplasma-Osmolalität, unangemessen hohen Ausschüttung von Antidiuretisches Hormon (ADH, Syn.: Adiuretin). Dies führt zu einer zu geringen Flüssigkeitsausscheidung über die Nieren mit Entstehung eines unzureichend verdünnten Urins. Die Erkrankung ist laborchemisch gekennzeichnet durch eine hypotone Hyperhydratation mit Verdünnungshyponatriämie (Serum-Natrium < href="http://de.wikipedia.org/wiki/Urin" title="Urin">Urins (> 100 mOsm/kg).[1] Häufigste Ursache ist ein kleinzelliges Bronchialkarzinom im Sinne eines paraneoplastischen Effekts.[2]

efavirenz synthese

Herstellung [Bearbeiten]

Die vielstufige Synthese von Efavirenz, inclusive der Racematspaltung einer Zwischenstufe, ist in der Literatur beschrieben.[2]

Pharmakologie [Bearbeiten]

Efavirenz gehört zur Substanzklasse der nichtnukleosidische Reverse-Transkriptase-Inhibitoren. Der Wirkstoff bindet nicht-kompetitiv an die Reverse Transkriptase von HIV-I, nahe der Substratbindungsstelle für Nukleoside. Dadurch wird die katalytisch aktive Bindungsstelle blockiert. Es können nur wenige Nukleoside binden und die Polymerisation wird deutlich verlangsamt.

zollinger ellisons syndrom

Zollinger-Ellisons syndrom är en ovanlig sjukdom orsakad av en eller flera gastrinproducerande tumörer, vanligen belägna i bukspottkörteln och ibland även i duodenum. De höga nivåerna av hormonet gastrin leder till en överproduktion av saltsyra i magsäcken vilket orsakar återkommande magsår och kan även ge diarré. Behandlingen är kirurgisk borttagning av tumören alternativt medicinsk behandling med protonpumpshämmare som sänker saltsyraproduktionen. Tumören kan i vissa fall sprida sig till lever och närliggande lymfknutor.

Duchennes muskeldystrofi är en progressiv

Bookmark and Share


Viktigaste symptomet är muskelförtvining främst i lår och bäcken men även andra delar av kroppen, i första hand extremiterna. Detta kan börja redan när barnet är nyfött men senast före sex års ålder. Problem med motorik, lätt att ramla, deformerade muskler, svimmning och förstorade vader är ett symptom som uppmärksammas före 6års ålder eller efter.


Den vanligaste orsaken till död är ofta komplikationer i andningsmuskulaturen eller hjärtarytmi. Vissa dör i tonåren, men medellängden är cirka 30år. Det finns även vissa som är över 50 år gamla idag enligt forskarna och framsteg inom forskningen har förbättrat möjligheten för de drabbade att leva längre.


Det finns ännu inget sätt att bota Duchennes muskeldystrofi. Fokus ligger istället på att minska de symptom som sjukdomen orsakar. Steroidhormoner används för att minska effekten av den muskelförsvagning som sjukdomen leder till. Lättare muskelträning kan rätt utförd motverka nedbrytningen av befintliga muskler. När andningsförmågan förändras på grund av försvagad andningsmuskulatur kan respiratoriska hjälpmedel sättas in. Ett vanligt läkemedel som används hos dom flesta med DMD är Kortison, det ska ha en effekt som gör effekten på muskelförsvagningen segare, men man minskar också risken att få skolios.

VIAGRA®, an oral therapy for erectile dysfunction, is the citrate salt of sildenafil, a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5).

Sildenafil citrate is designated chemically as 1-[[3-(6,7-dihydro-1-methyl-7-oxo-3-propyl-1H- pyrazolo[4,3-d]pyrimidin-5-yl)-4-ethoxyphenyl]sulfonyl]-4-methylpiperazine citrate and has the following structural formula:

VIAGRA (sildenafil citrate) is formulated as blue, film-coated rounded-diamond-shaped tablets equivalent to 25 mg, 50 mg and 100 mg of sildenafil for oral administration. In addition to the active ingredient, sildenafil citrate, each tablet contains the following inactive ingredients: microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, magnesium stearate, hypromellose, titanium dioxide, lactose, triacetin, and FD & C Blue #2 aluminum lake.

Is soma an addiction? Do you need to relax?

Disclaimer: if taken without control or the help of a doctor, this can become a very addictive drug and can cause real damage, so no action should be taken without asking a doctor first.

Carisoprodol is a centrally-acting skeletal muscle relaxant whose active metabolite is meprobamate. Although several case reports have shown that carisoprodol has abuse potential[1] both by itself and as a potentiator of hydrocodone, dihydrocodeine, codeine and similar drugs, it continues to be prescribed in North America, alongside cyclobenzaprine. In Europe, doctors favor cyclobenzaprine due to its lower abuse factor. In the United Kingdom, benzodiazepines are preferred instead. Carisoprodol is a colorless, crystalline powder, having a mild, characteristic odor and a bitter taste. It is slightly soluble in water and freely soluble in alcohol, chloroform and acetone. Its solubility is practically independent of pH.

Carisoprodol is marketed in the United States under the brand name Soma, and in the United Kingdom and other countries under the brand names Sanoma and Carisoma. Carisoprodol is especially useful against various types of pain (whether or not related to muscle spasm) because of its analgesic-sparing (potentiating) effect on opioid analgesics. Carisoprodol is available by itself or mixed with aspirin and in one preparation (Soma Compound With Codeine) along with codeine and caffeine as well.

As of November 2007 Carisoprodol (Somadril, Somadril comp.) has been taken off the market in Sweden due to problems with dependence, abuse and side effects. The agency overseeing pharmaceuticals has considered other drugs used with the same indications as carisoprodol to have the same or better effects without the risks of the drug.[2].

In the EU, the European Medicines Agency has issued a release recommending that member states suspend marketing authorization for this product. [3]

As of March 2009, carisoprodol is considered to be a schedule CIV by the states of Florida, Arizona, Idaho, Minnesota, Kentucky, Hawaii, and Washington State (not verified, WA still using DEA scheduling). Beginning in July 2002, Florida led the state movement to schedule carisoprodol when a state bill was passed due to an understanding within state drug enforcement circles that the drug was becoming more widely abused. Possession of the drug without a valid prescription in the state of Florida is now a third degree felony. The rest of the United States, excluding the above named states, falls under the DEA scheduling for the drug, which considers carisoprodol a non-scheduled chemical, meaning that carisoprodol is considered a general prescription medication by the federal government of the United States, with oversight provided solely by the U.S. Food and Drug Administration (FDA).
