HIV/AIDS Drugs In article 2203198, Garry Laverty and co-workers develop a long-acting injectable drug delivery implant composed of short peptide sequence attached to the zidovudine. Upon injection, this aqueous solution-based formulation rapidly forms drug-releasing hydrogel in response phosphatase enzymes present within skin space. Clinically relevant concentrations zidovudine were delivered r...
Abstract: Background: Zidovudine (Azidothymidine, AZT) is widely used in the treatment of Acquired Immuno Deficiency Syndrome (AIDS) and related conditions, either alone or combination with other antiviral agents to combat HIV. AZT a Biopharmaceutical Classification System (BCS) class III drug has various disadvantages. Thus, potential candidate for delivery via lipid-based system. Materials Me...
The article is devoted to the study of acute toxicity drug «Zidovudine»
Two- and three-drug combinations of lamivudine or stavudine with other antiretroviral drugs were evaluated for activity against human immunodeficiency virus type 1 (HIV-1) activity in peripheral blood mononuclear cells. Other agents included zidovudine, didanosine, nevirapine, and saquinavir. Paired zidovudine-sensitive and -resistant clinical HIV-1 isolates were used. Additive or synergistic i...
BACKGROUND Amdoxovir acts synergistically with zidovudine in vitro and the combination prevents or delays the selection of thymidine analogue and K65R mutations. In silico studies have shown that a reduced dose of zidovudine (200 mg) results in decreased zidovudine-monophosphate levels, associated with toxicity, while maintaining zidovudine-triphosphate levels, which are associated with antivir...
Human immunodeficiency virus type 1 (HIV-1) strains dually resistant to zidovudine and lamivudine (3TC) may arise during zidovudine-3TC combination therapy. The objective of this cross-sectional study (n = 43 patients) was to test the association between therapy response (clinical and immunologic) to zidovudine-3TC and the level of phenotypic zidovudine resistance and zidovudine resistance-asso...
Neuromuscular weakness is often found in patients receiving zidovudine therapy due to mitochondrial damage. Effect of zidovudine was evaluated in indirectly and directly stimulated isolated rat phrenic nerve hemidiaphragm preparations, by cumulative dose response curve with square wave pulses, 0.5 ms duration of 2 Hz at every 10 s. To understand the observed effect of zidovudine, interaction st...
Cross-resistance between zidovudine, stavudine, and lamivudine was studied, using purified recombinant reverse transcriptase from a zidovudine-susceptible and -resistant pair of clinical isolates of human immunodeficiency virus type 1. The zidovudine-resistant isolate exhibited low-level cross-resistance to both stavudine and lamivudine in drug susceptibility assays. Enzyme from the resistant i...
AIMS The objective of the study was to determine the effect of multiple doses of rifampicin on the steady-state pharmacokinetics of zidovudine and its 5'-glucuronosyl (GZDV) and 3'-amino (AMT) metabolites. METHODS Eight asymptomatic HIV-infected patients (seven male, one female) participated in this three-period longitudinal study. Each patient received zidovudine (200 mg every 8 h) for 14 da...
