Pharmacokinetic Study in Patients With Chronic Kidney Disease and Healthy Volunteers (CKD)
May 28, 2013 updated by: University of California, San Francisco
Pharmacokinetic Study of Propranolol, Losartan, and Eprosartan in Healthy Volunteers and Patients With Chronic Kidney Disease
The purpose of this study is to find out how chemicals in the blood of patients with chronic kidney disease affect how medications are removed from the body.
The patient will take one dose of three different drugs, one on each week, for a total of three single doses.
The investigators want to find out if these three different medications are affected in different ways by the chemicals in the blood of patients with kidney disease.

Detailed Description
It has been demonstrated that proteins known as drug transporters in different human organs and tissues are important for a drug to be absorbed, distributed, metabolized, and eliminated (ADME)18.
The chemical properties of drugs can affect whether it needs a transporter protein to enter the cell or not.
It is not well known how these proteins are affected in chronic disease and how different drugs may be absorbed, metabolized, or eliminated differently in certain diseases.
Preliminary studies suggest that some drugs (those requiring drug transporter proteins) may show altered elimination in the presence of uremic toxins.
Uremic toxins are substances accumulated in the blood of patients with chronic kidney disease and many are not removed through hemodialysis (HD).
We hypothesize that the different classes of drugs (BDDCS class1, 2, and 3) will have different degrees of changes in AUC, meaning that for a class 1 drug we would see less of a change in AUC than in a class 3 drug because a class 3 drug requires transporters.
Previous studies can't make that comparison because they used different patients for each drug, so even if there were a change in a class 1 drug, it can't be compared to a class 3 drug.
In order to get an accurate comparison, we will test the three drugs on the same patient and see how he AUC changes from drug to drug within the same patient comparing it to the healthy volunteer (taking the same three drugs).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Chronic Kidney Disease
Propranolol, Losartan, and Eprosartan will be administered to patients who have been diagnosed with Chronic Kidney disease and have a glomerular filtration rate (GFR) below 40ml/min.
|
Propranolol 40mg PO will be given with 6oz of water.Blood samples will be obtained for 12 hours to determine the medication concentration in the plasma.
There is no therapeutic effect on this study, since patients will receive a low single dose of the medication, and we'll assess the different pharmacokinetic parameters based on the concentrations of the medicine in plasma.
Other Names:
Losartan 50mg PO will be given with 6oz of water.
Blood samples will be obtained for 12 hours to determine the medication concentration in the plasma.
There is no therapeutic effect on this study, since patients will receive a low single dose of the medication, and we'll assess the different pharmacokinetic parameters based on the concentrations of the medicine in plasma.
Other Names:
Erythromycin 125mg PO will be given with 6oz of water.
Blood samples will be obtained for 12 hours to determine the medication concentration in the plasma.
There is no therapeutic effect on this study, since patients will receive a low single dose of the medication, and we'll assess the different pharmacokinetic parameters based on the concentrations of the medicine in plasma.

Experimental: Healthy Volunteers
Propranolol, Losartan, and Eprosartan will be administered to healthy volunteers without chronic kidney disease.
