From conformational analysis, we have determined the two lowest energy crystal structures for the hard segments of 4,4Ј-diphenylmethane diisocyanate/1,4butanediol (MDI/BDO)-based polyurethane elastomer. Both crystal forms give prominent X-ray scattering at ϳ7.6 Å. In one crystal form, (1), there is
minophen following oral administration of equivalent doses of pacetaminophenyl decanoate. The availability of drug from this ester form was 34% of that produced by acetaminophen. Concomitant administration of p-acetamidophenyl decanoate, pancreatic lipase (3 Wilson units/mg), and calcium chloride in
