Bumetanide is nearly totally absorbed from the gastro-intestinal tract. After peroral administration, a bioavailability of between 80-95% is observed. Diuresis begins within ½-1 hour with a peak effect between 1 and 2 hours. The diuretic effect lasts up to about 4 hours. Bumetanide is eliminated with half-life ranging from between 1 to 2 hours after oral administration of a dose of -2 mg. It is strongly bound to plasma proteins and renal excretion of unchanged drug accounts for about half of the total clearance. The hepatic metabolism and biliary excretion accounts for the other half. The primary metabolites are conjugated alcohols of bumetanide. No active metabolites have been found. Bumetanide has a steep dose response curve.

Seven steroidal glycosides, along with one known glycoside, were isolated from the rhizomes of Ruscus hypophyllum (Liliaceae). Comprehensive spectroscopic analysis, including 2D NMR spectroscopy, and the results of acid hydrolysis allowed the chemical structures of the compounds to be assigned as (23 S ,25 R )-23-hydroxyspirost-5-en-3β-yl O -α- l -rhamnopyranosyl-(1   →   4)-β- d -glucopyranoside ( 1 ), 1β-hydroxyspirosta-5,25(27)-dien-3β-yl O -α- l -rhamnopyranosyl-(1   →   4)-β- d -glucopyranoside ( 2 ), (22 S )-16β,22-dihydroxycholest-5-en-3β-yl O -α- l -rhamnopyranosyl-(1   →   4)-β- d -glucopyranoside ( 3 ), (22 S )-16β-[(β- d -glucopyranosyl)oxy]-22-hydroxycholest-5-en-3β-yl O -α- l -rhamnopyranosyl-(1   →   4)-β- d -glucopyranoside ( 4 ), (22 S )-16β-[(β- d -glucopyranosyl)oxy]-22-hydroxycholest-5-en-3β-yl β- d -glucopyranoside ( 5 ), (22 S )-16β-[(β- d -glucopyranosyl)oxy]-3β,22-dihydroxycholest-5-en-1β-yl O -α- l -rhamnopyranosyl-(1   →   2)-(3,4-di- O -acetyl-β- d -xylopyranoside) ( 6 ), and (22 S )-16β-[(β- d -glucopyranosyl)oxy]-3β,22-dihydroxycholest-5-en-1β-yl O -α- l -rhamnopyranosyl-(1   →   2)- O -[β- d -xylopyranosyl-(1   →   3)]-β- d -xylopyranoside ( 7 ), respectively. This is the first isolation of a series of cholestane glycosides from a Ruscus species.

It will always be this way because when someone is in pain they want to be out of pain as quickly as possible.  In that regard, people will follow the palliative model brought forth by allopathics.  But once out of pain, they may try to "look deeper" into the pain and it's many possible causes.  Removing the cause, not so much, if it involves changing eating habits.  I, for one, love sourdough bread, raw dairy and potatoes - so I have no intention of eliminating them from my diet.  I don't eat those foods every day (except the dairy) but I still won't be giving them up after almost 60 years of no problems from them.  I probably am the exception, in that I rare;y take or need pain killers, but instead I use massage, acupressure, etc.
