“ABSTRACT While in vitro results at clinically relevant concentrations do not predict abacavir (1592U89) interactions with drugs highly metabolized by cytochrome P450, the potential does exist for a pharmacokinetic interaction between abacavir and ethanol , as both are metabolized by alcohol dehydrogenase.”
“The geometric least squares mean area under … curve extrapolated to infinite time for abacavir increased 41% (from 11.07 to 15.62 μg · h/ml), and the … increased 26% (from 1.42 to 1.79 h) in the presence of ethanol (mean ethanol maximum concentration … of 498 μg/ml).”
“The percentages of abacavir dose recovered in urine as abacavir and its two major metabolites were each altered in the presence of ethanol , but there was no change in the total percentage (≈50%) of administered dose recovered in the 12-h collection interval.”
