Locate Peer-reviewed Chemical Literature for a Specific Drug for a Particular Indication?

TOPIC: In this example, you want to find peer-reviewed literature for the drug Lipitor, a cholesterol-lowering drug using Embase® (File 72. 73) to find the CAS® Registry Number for Lipitor.

The CAS Registry Number is a unique number given to chemical substances. You will SELECT and SAVE the CAS Registry Number(s) and then you will search the biomedical literature, including Embase using the saved CAS Registry Numbers.

Biomedical databases such as MEDLINE® (File 154, 155) and BIOSIS Previews®(File 5, 55) are examples of files that contain literature related to research and development of drugs and have a CAS Registry Number field (RN=).

  High-density lipoproteins (HDL) are small particles comprised of phospholipids and stabilizing proteins, which carry cholesterol and triglycerides in the blood stream. The incidence of cardiovascular events is high in patients with low level of HDL-cholesterol (HDL-C). In the present study, we defined The PH index [Deltacoronary plaque volume/DeltaHDL-C] index as a putative clinical index of cholesterol efflux capacity of HDL from atheromatous plaque. The present study investigated the PH index in response to treatment with different types of HMG-CoA reductase inhibitors (statins), in contrast to similar changes in the PL index [Deltacoronary plaque volume/Deltalow-density lipoprotein-cholesterol (LDL-C)] by the same statins. Using the 2000-2011 PubMed database, the search keywords were "statins" and "intravascular ultrasound (IVUS)" and "plaque volume". Cross references were checked. PubMed search identified 29 references, and finally 4 ....
