Pharmacokinetics and Disposition of Rilpivirine (TMC278) Nanosuspension as a Long-Acting Injectable Antiretroviral Formulation

Pharmacokinetics and disposition of rilpivirine (TMC278) nanosuspension as a long-acting injectable antiretroviral formulation.

The next-generation human immunodeficiency virus type 1 (HIV-1) nonnucleoside reverse transcriptase inhibitor rilpivirine (TMC278) was administered in rats and dogs as single intramuscular (IM) or subcutaneous (SC) injections, formulated as a 200-nm nanosuspension. The plasma pharmacokinetics, injection site concentrations, disposition to lymphoid tissues, and tolerability were evaluated in sup...

Pharmacokinetics of an injectable long-acting formulation of doxycycline hyclate in dogs

Based on its PK/PD ratios, doxycycline hyclate (DOX-h), a time-dependant antibacterial, is ideally expected to achieve both sustained plasma drug concentrations at or slightly above the MIC level for as long as possible between dosing intervals. Pursuing this end, a poloxamer-based matrix was used to produce a long-acting injectable preparation (DOX-h-LA) and its serum concentrations vs. time p...

Long-acting antiviral agents for HIV treatment

PURPOSE OF REVIEW Long-acting antiretroviral (ARV) agents are currently under development for the treatment of chronic HIV infection. This review focuses on data recently produced on injectable ARVs for patients living with HIV/AIDS and on the patients' perspectives on the use of these agents. RECENT FINDINGS Crystalline nanoparticle formulations of the nonnucleoside reverse transcriptase inh...

Long-acting rilpivirine for HIV prevention.

PURPOSE OF REVIEW Long-acting injectable antiretroviral (ARV) formulations are being developed for the treatment and prevention of HIV infection. The purpose of this review is to summarize recent preclinical and clinical data on TMC278 (rilpivirine), a nonnucleoside reverse transcriptase inhibitor (NNRTI), that is being developed for both a treatment and prevention indication. RECENT FINDINGS...
