|HIV Infection HIV Infections||Drug: Raltegravir||Not Applicable|
A large number of people who are infected with HIV have acquired it through injection drug use. Some of these people are currently being treated with Buprenorphine for their addiction and with medications for HIV infection. Raltegravir is a medication that was approved by the Food and Drug Administration (FDA) for the treatment of HIV infection. Raltegravir acts by making it more difficult for the virus that causes AIDS to multiply and cause more damage to the immune system in someone who is HIV infected.
Earlier studies looking at the effect of Buprenorphine and HIV medications have shown that Buprenorphine and some HIV medications act differently when taken together. It is important to learn if taking Buprenorphine and HIV medications together results in changes in the blood level of either medication. If the HIV medication affects the level of Buprenorphine in the blood, an individual taking Buprenorphine and HIV medications may experience symptoms of withdrawal, even while taking their usual dose of Buprenorphine. On the other hand, if Buprenorphine decreases the amount of HIV medication in the blood, then the HIV medication may be less effective in controlling HIV infection. It is therefore important to learn if Raltegravir and Buprenorphine will affect each other when taken together.
In order to learn about the effects of Buprenorphine and Raltegravir, we will need to measure the amount of Buprenorphine in your blood for 24 hours before you have taken Raltegravir and then compare that to the amount of Buprenorphine in your blood after you have taken Buprenorphine and Raltegravir together .
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||12 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||A Study of the Pharmacokinetic and Pharmacodynamic Interactions Between Raltegravir (Isentress) and Buprenorphine|
|Study Start Date :||March 2009|
|Actual Primary Completion Date :||December 2009|
|Actual Study Completion Date :||December 2009|
Buprenorphine and Raltegravir co-administration
400 mg of raltegravir orally twice daily together with normally prescribed stable dose of buprenorphine for a minimum of 4 days and up to 14 days.
Other Name: Isentress
- Area Under the Curve (AUC) of BUP/NLX With Raltegravir (hr*ng/mL) [ Time Frame: 6-14 days after beginning co-administration of drugs ]PK parameters of BUP were determined by non-compartmental methods. AUC of BUP was determined by use of the trapezoidal rule.
