Oral and sublingual drops and liquid preparations include and with out added flavoring. Its relative effectiveness by way of transmucosal routes (i.e. sublingual, buccal, rectal) is just like that of codeine, and, like codeine, it is also metabolized within the liver to stronger metabolites (see below).
