Ezetimibe pharmacokinetics
Common Questions and Answers about Ezetimibe pharmacokinetics

There was an in vitro study on ezetimibe inhibiting HBV DNA production. The ed50 was fairly low and in a similar range as lamuvidine. So it looked very interesting. But in an in vitro study you have a constant exposure to the drug, which is impossible to achieve in vivo. And the cells used are not the same as regular hepatocytes in human liver, with many differences in gene expression and cellular physiology.
also statins like simvastatin were reported to boost response a little but better not mix 2 statins, in a report researchers of ezetimibe effect on hbv and hcv suggested the use of ezetimibe with interferon but without simvastin
ezetimibe dose is 10-20mg daily but human trials with dose 50mg daily for a limited time did not find any sides or toxicity
- Absorption, oral: time to peak concentration 7h
- Elimination half-life = 12 h
(It says also that in general it can be administered once daily because it has a 24 h effect.Why?)
- Can you give another example to clarify it better please?
- When it says divide in 2 doses , does it mean only in the morning and dinner? 3 doses (morning-lunch-dinner)?
Thank you for taking the time to answer!!
Your biliary acids were very low, which shows that there is no blockage of the HBV receptor. You have to consider the pharmacokinetics of the ezetimibe and possibly also the irbesartan. Blockage is only effective if it is a 24 hour continuous affair. If you leave the door open for the rats just one hour a day, your house will be filled with them.
to see if the irbesartan does a better job in vivo, you can simply measure your bile acids now after you take it.
The FDA-approved drug ezetimibe (sold under the trade-name Zetia) is readily available and perfectly targeted to the receptor, Sainz said, so the researchers had an ideal method for testing NPC1L1's involvement in HCV infection.
The researchers showed that ezetimibe inhibited HCV infection in cell culture and in mice transplanted with human liver cells. And, unlike any currently available drugs, ezetimibe was able to inhibit infection by all six types of HCV.
You could consider going for a higher dose of Lipitor, another way to go is to consider taking a drug that limits cholesterol absorption such as Ezetimibe. There is a combination drug Simvastatin and ezetimibe that may be better in controlling cholesterol. Discuss these drugs with your doctor.
Best of luck to you. Stay positive.
no study for its activity on hbv, we do know it has activity but the trial has never started
simvastatin lowers hcc 50% and prevents fibrosis/cirrhosis so it is indicated on all hbver, this has thousands of pateints studied for decades to find this data on hcc
you better use simvastatin instead other statins, also ezetimibe has in vitro effect on hbv so these are the best choices on hbvers
I can't help out on the pharmacokinetics, but your reasoning is sound: it doesn't make sense to dose so that the drug runs out.
I'd query Schering-Plough as well as your hepatologist, if I were you.
Please give me a heads-up if you solve the riddle.
About two years ago my doctor added ezetimibe to my regimen. It has been lowering my bad cholesterol how ever the first of this month I missed taking them for about a week and for the first time in years I felt less fatigued. I do have Fibromyalgia which is usually the cause of my fatigue, but this is a different type of fatigue. I have not restarted either of the cholesterol meds back because I have felt so much better. I know I need to talk to my doctor about it.
I had very high cholesterol, due to familial hypercholesterolemia, and living on just salad for weeks did nothing for the levels. Statins have worked wonders in bringing the levels down but I also take Ezetimibe which slows absorption of fats through the gut lining. Now I can basically eat what I want and my cholesterol levels are always within the range required.
Cholesterol in the blood is not the cause of disease, it's like a side effect from the initial problem.
