Laxatives can be divided into 5 groups.Each of them is the most effective drugs, which are different in mechanism of action.The first group includes irritating drugs - they are the most effective and fast time-steps.These include "Regulaks", "bisacodyl", "Guttalaks", and good help from natural senna leaves, castor oil and buckthorn bark.The mechanism of action they share - a stimulation of the receptors of the colon.In this stimulates peristalsis, laxative effect arises after about 10 hours after ingestion.Often, these substances can not be taken as they can cause atrophy of the receptors and goiter.
The second group includes osmotic laxatives, which hold a large amount of fluid in the lumen of the intestine, and the stool thereby soften.They are effe
ctive and do not cause a syndrome "indolent ulcer."Chronic administration, especially in the elderly, there may be an insufficient number of sodium and potassium salts.Citrate and polyethylene glycol - are examples of the most effective osmotic laxatives.
most safe and effective laxative, are prebiotics - substances that are not digested in the stomach and pass into the lower sections of the intestine, which stimulate the growth of beneficial microflora."Duphalac" and "Prelaks" further contribute to the stimulation of muscle cancer, restore its function.
Well help bulk laxatives, which are represented by polysaccharides.These include, for example, agar-agar, methyl cellulose and bran.Bulk laxatives are able to absorb water and swell under its influence.At a certain concentration is formed contractile wave that pushes the stool.Nevertheless, they are very soft, gradually freeing the intestines.Because of side effects is worth noting bloating and flatulence.
The latter group includes detergents.And if simpler, it fennel oil, vaseline and sweet almond oil.The effect of these is faster than the others, because the oil is already operating in the small intestine.Detergents soften the stool, help them slip through the intestines.Only here the frequent use of these drugs causes a deficiency of fat-soluble vitamins, which is a serious side effect.
