Osmotic laxatives exhibit a linear dose response

Osmotic laxatives simply pull water into the intestines. In this video, we go through the process of applying your knowledge to figure out the most dangerous side effects of osmotic laxatives. We also explore the differences between a 'linear dose response' seen with osmotic laxatives, and the standard drug response seen with administration of most medications. While "the more you take, the greater the effect" is relevant to the osmotic laxatives, it is dangerous to think that our other medications will exhibit the same response.

Osmotic laxative may not only induce an electrolyte inbalance, but especially Epsom salt may lead to the kidney kidney in the case of a false dosage.

Can these osmotic laxatives be administered anally, supp or small volume enema? At a very cautious dose, so only the very hard dehydrated stool in or near the rectum is affected.
Are these osmotic laxatives also not for prolonged use?
Does psyllium husks created an osmotic pull into the bowel? Or just use up and retain the water in the bowel?
