Here's the main thing to remember-- these drugs work mainly by slowing the bowel down so that stuff stays in longer, and more water is absorbed so the result is very hard, like concrete. Fiber (bulking agents) work by retaining water, so the stool cannot get TOO hard. Generally real problems with them are NOT caused by them per se, but rather by misuse of them in which you have one or more meals in which they are not taken, with fiber meals before and after. This results in one small concrete plug from the normal meal, which then sticks to and gums up everything on either side, so you have one giant mass which doesn't want to move. You've seen the result. Thus, the important thing with bulk laxatives is that you must have some with each and every meal you eat. On narcotics and fiber, even ONE meal low residue meal will get you in the end, so to speak, a couple of days later. The result is worse than no fiber at all, because at least with no fiber you reduce all meals to a series of rabbit or deer pellets. With fiber you have to go all the way, or not at all. That said, by far the best bulk laxative I know if is natural banana. This has not only fiber for bulk, but also other stuff for lubrication and even some serotonin which is a mild stimulant. We humans are deluxe model chimps, and we're built to eat bananas! If you can stand to eat three large bananas a day, you'll be well served. If not, banana as frequently as you can, and some fiber with meals you don't get banana. If you don't like Metamucil (made from psyllium seed hulls), try citrus fiber (Citrucel) which holds a little more water. Don't forget an extra glass of water with the meal. Finally, you may find that bulking agents aren't enough, and you have to resort to magnesium. Here the same rules apply as to frequency. A little with each meal works better than one big blast each day, since that can result in cramps and water behind one harder bit of residue. Magnesium is harmless unless you have kidney disease (which you'd know about if you had it that bad) so generally you can experiment to see how much magnesium it takes per meal. If you really get to hating the cherry flavored Phillips, there are also magnesium oxide tablets and milk of magnesia tablets which are equivalent. They absorb enough water to work from the meal you take them with, if you remember the extra glass. There is new on the laxative market a slightly different kind of osmotic laxative which can be used in place of magnesium, and is more pleasant tasting than Phillips. It's called MiraLax, and is the same polyethylene glycol (a soluble plastic) which has long been used for colonoscopy prep. It's about as inert as fiber, and long term studies show it's probably safe for the long term (although the packaging recommends 2 weeks). I think it's still by prescription only, but that's because it's relatively new for this use. Stay away from bisacodyl/Dulcolax and other stimulant laxati ves-- they work but your body adapts to them and becomes dependent. Bulk and osmotic agents such as are discussed above don't have so much of a problem that way. Lastly, there are "stool softeners" (docusate, PeriColase, etc) which are supposed to soften stool but actually probably work partly by irritation, since your body adapts rapidly to them also. Again, not a good idea for long term use.

However, it's a fact that bisacodyl's effects rapidly wear off (so says the PDR, the texts and my own experience in practise using it), and if it was a mere stool softener by means of surfactant properties, this would hardly be true.

Different groups, No? COMMENT: Yeah, sorry, that was a brain spasm, and I meant to say docusate above. Bisacodyl and docusate are formally labeled as being in different groups or classes of laxatives, but BOTH of them are in fact bowel irritants. The difference is mainly one of degree. The detergent docusate (the so-called "stool softener") shows its irritative action in the fact that it increases fluid leakage into the gut, and can cause rectal mucosal damage (as you read in the PDR). This is not surprising. Detergents cause havoc with mucosa, a fact which seems to shock, but shouldn't surprise anybody whose ever had soap in their eyes. Your cell membranes are soap-like molecules which are susceptible to being emulsified in bad ways and washed away, and the amazing thing is that cells unprotected by epidermis stand up to detergents as well as they do. Detergents are so disruptive to cell membranes that a simple detergent called nonoxyl-9 has been used as a spermicide contraceptive. It also dissolved the lipid coated HIV virus in the test tube, and was once not so long ago recommended as part of safe-sex programs. Alas, the stuff also played havoc on the delicate mucosal membranes of the vagina, and there is evidence that the resulting irritation made people MORE rather than less susceptible to HIV infection, overall. It's the same docusate mistake in another guise. They labeled nonoxyl-9 a "spermicide," and virus-cide, you see, and not a "lipid disrupting detergent and mucosal irritant." Labels. All knowledge is one piece. Divisions in learning are put there for the benefit of our tiny brains, but they aren't there in reality. A lesson HERE also applies THERE, if you can just learn to see beyond labels. Anyway, the body rapidly adapts to the action of both irritant classes of laxatives. The only honest to God "stool softeners" which don't chew on the fragile gut wall, are the osmotic agents and soluble fibers. SBH |
