Nitrate III by H-J Engel
In vielen pharmakologischen Instituten und kardiologischen Kliniken werden in zunehmendem Umfang Nitrate experimentell und klinisch untersucht. Dies ist iiberraschend, wenn man bedenkt, daB bereits vor iiber hundert Jahren Brunton und Murrell im Lancet iiber die giinstige Wirkung dieser Substanzen bei der Angina pectoris berichtet haben. Seit den beiden vorausgegangenen Nitrat-Symposien, in Stockholm 1975 und Berlin 1978, sind - wie erwartet - eine Menge neuer Erkenntnisse gewonnen worden. Dieses Wissen betraf Pharmakologie, Pharmakokinetik und Pharmako- dynamik der Nitrate, besonders aber auch ihre klinischen Wirkungen bei akuter und chronischer Ischamie des Herzens und bei schwerer dekompensierter Herz- insuffizienz. Daran gemessen war der Fortschritt bei der Erforschung des moleku- laren Wirkungsmechanismus der Nitrate eher bescheiden. Obwohl die meisten U ntersucher iibereinstimmen, daB Anderungen von intrazellularem Calcium wahrscheinlich der Hauptwirkungsmechanismus sind, durch welchen Nitrate zu einer Abnahme des Tonus glatter GefaBmuskulatur fiihren. Der genaue art ihrer Wirkung ist noch unbekannt. 1m Gegensatz dazu sind die dosisabhangigen Unterschiede der Wirkungen auf das venose und arteriolare GefaBsystem seit langem gut bekannt. Die Behandlung mit Nitraten stand erneut im Mittelpunkt der Diskussionen. Ausfiihrlich wurde die Frage der Entwicklung einer Toleranz nach Langzeit- Therapie mit Nitraten diskutiert. Dabei wurde der Ausdruck Pseudo-Toleranz zur Beschreibung der Anpassung des Kreislaufsystems an die chronische Vasodila- tation verwendet. Diese chronische Vasodilatation ist fiir die Langzeit-Prophylaxe sowohl bei stabiler als auch bei instabiler Angina pectoris (d. h. bei Zustanden mit erhohtem Vasomotorentonus-Spasmus) von besonderer Bedeutung.

"I was paying $11.99/month for Kindle Unlimited but realized I was renting books, not owning them. Bought this PDF and it's mine forever. Never going back to Kindle."
"Switched from Kindle to these PDFs. Same book, but I actually OWN it now. No monthly fees, no app required. Worth every penny."
"Kindle Unlimited kept raising prices. This is a one-time purchase and the file is permanently on my iPad. Best decision I've made for my reading habit."
"I compared Kindle vs this store. Kindle is cheaper monthly but you don't own anything. Here I paid once and the PDF is mine for life. Highly recommend."
"Left Kindle behind after they removed a book I was reading mid-series. With this PDF, nobody can take it away from me. True ownership feels good."
"Was skeptical about paying $18.95 when Kindle shows $3.99, but then I did the math — Kindle Unlimited is $143/year! This is way better value long term."
"Love that I can read this on any device without installing the Kindle app. The PDF works on my laptop, phone, and tablet seamlessly. So much freedom."
"My Kindle subscription was getting expensive. Switched to buying PDFs here and I'm saving money while actually building a permanent digital library I control."
