| pubmed-article:1234488 | pubmed:abstractText | The effect of syrup, B.P. and codeine phosphate syrup, B.P.C. on blood alcohol levels was determined in six normal subjects. 2 Treatment with syrup alone had little or no influence on the concentration of ethanol in blood. 3 In contrast, pretreatment with codeine phosphate syrup significantly reduced alcohol absorption, as assessed by the maximum blood levels achieved or the area subtended by the blood concentration-time curve. It is suggested that the diminished absorption of ethanol is related to the pharmacological action of codeine on the stomach. 4 It was considered that the concentration of ethanol in linctuses or syrups containing codeine was unlikely to have any significant effect on the central nervous system. | lld:pubmed |
