Action of oral and parenteral bethanechol on decompensated bladder.

A double blind balanced Latin-square study was conducted on 20 adult patients with decompensated bladders to determine the relative effectiveness of oral and parenteral bethanechol chloride (Urecholine) on the stretch response of bladder muscle. Detrusor reaction was measured by modified cystometry. Five mg. of subcutaneous bethanechol chloride produced a significant increase in intravesical pressure which was more rapid in onset, of larger magnitude, and of shorter duration than oral doses of 100 and 200 mg.
