Slobodan Vukičević: Osteoporoza u ženaOd Alendronata do OsteogrowaBrijuni, 8-11 rujan 2011
Tolerancija i sigurnost • prospektivne RCT studije • bisfosfonati grupa lijekova najopsežnije proučena u povjesti medicine • od 1969 sigurnost i učinkovitost proučavana u nizu opsežnih RCT studija u bolesnika sa osteoporozom, Padgetovom bolesti, mijelomom i koštanim metastazama. Bisfosfonati koji sadrže dušik proučeni su u više od 60,000 bolesnika u trajanju od 3 ili više godina • do 201. prepisano je više od 330 milijuna oralnih bisfosfonata širom svijeta
Gideon Rodan • vodio alendronat od oktrića do FDA odobrenja • čovjek največeg moralnog integriteta i zato su klinički rezultati alendronata 100% pouzdani i bez post-hoc prilagodbi • otvorio put za novu klasu lijekova His outstanding scientific contributions included: isolation and characterization of the first transformed osteoblastic cell line (ROS 17), the dissection of the PTH signal transduction mechanisms, the concept of osteoblast-osteoclast interactions, the cloning of alkaline phosphatase, and the roles of steroids and prostaglandins in bone metabolism. As Director of the Department of Bone Biology and Osteoporosis Research at Merck, he fostered the development of the first bisphosphonate approved for treatment of osteoporosis and provided detailed studies of the mechanisms of action of the bisphosphonates.
