- Plantago seed
- DrugBank Accession Number
- DB11097
- Background
Platango seeds refer to the seeds collected from various species of plantago trees. It is found in some laxatives for treating occasional constipation and restoring regularity in bowel movements. Its potential benefit in maintaining remission in ulcerative colitis has been studied 1.
Regardless, this agent is most predominantly used as a gentle laxative agent in many parts of the world that is more commonly referred as psyllium or psyllium husk.

The active ingredient psyllium husk is comprised of the episperm and collapsed adjacent layers removed from the seeds of Plantago afar L. or Plantago indica L. 3. Psyllium husk is abundant in alimentary fibres and mucilages, with its mucilage content in particular being higher than that of other plantago species 3. Specifically, psyllium husk is capable of absorbing up to 40 times its own weight in water 3. Psyllium husk consists of 85% water-soluble fibre - it is subsequently partly fermentable (in vitro 72% unfermentable residue) and acts by hydration in the bowel 3.
Gastrointestinal tract motility and transit rate is capable of being modified by psyllium husk via mechanical stimulation of the gut wall as a result of the increase in intestinal bulk by water and the decrease in viscosity of the luminal contents 3. Taken with an adequate amount of liquid (at least 30 ml per 1 g of the agent), psyllium husk produces an increased volume of intestinal contents as a result of its highly bulking properties and therefore a stretch stimulus which triggers a defecation 3. Concurrently, the swollen mass of mucilage generates a lubricating layer that makes the transit of the intestinal contents easier 3.
- Mechanism of action
Psyllium seeds are comprised of dietary fibre which, when mixed with water forms a gel-like mass that works as a mild laxative Label. This gel-like mass subsequently moves down a patient's digestive system and makes stools softer by increasing their water contents Label. At the same time psyllium seed lubricates the intestine, which improves the transit of stools Label. Moreover, as the presence of the gel-like mass increases the stool bulk it also increases the tension and/or the stretch stimulus in the bowel wall which serves to trigger bowel movements Label.
The dietary fibre of which psyllium husk is comprised is fermented to various degrees by bacteria in the colon, resulting in production of carbon dioxide, hydrogen, methane, water, and short chain fatty acids, which are absorbed and brought into the hepatic circulation 3. In humans, such fibre reaches the large bowel in a highly polymerized form that is fermented to a limited extent, resulting in increased fecal concentration and excretion of short chain fatty acids 3.
- Absorption
Psyllium husk is capable of hydration and swelling to form a mucilage because it is only partially solubilized 3. The polysaccharide dietary fibres of which psyllium husk is comprised of need to be hydrolyzed to monosaccharides before intestinal absorption can occur 3. The sugar residues of the xylan backbone and side chains are joined by beta-linkages however, which cannot be broken by human digestive enzymes 3.
Less than 10% of the mucilage gets hydrolyzed in the stomach, with formation of free arabinose 3. Intestinal absorption of the free arabinose is about 85% to 93% 3. As a consequence, psyllium remains predominantly in the gastrointestinal tract as a 'bulk' agent that passes largely unchanged throughout the gut 4. The agent has remarkable water holding capacity because of its high hemicellulose content 4.
- Volume of distribution
Psyllium husk when administered as intended largely undergoes little absorption into the body and plasma.
- Protein binding
The protein binding of psyllium husk is not formally documented at this time. Regardless, because psyllium husk is largely not adsorbed when administered, it is believed that the drug may not exhibit any kind of protein binding 2.
- Metabolism
As psyllium remains largely in the gut as a 'bulk' agent that passes predominantly unchanged throughout the gastrointestinal tract, there is little opportunity for marked absorption into or metabolism by the body 4.
- Route of elimination
Psyllium husk when administered as indicated is usually excreted in the faeces 2.
- Half-life
The half-life of psyllium husk is not formally documented at this time. Regardless, because psyllium husk is largely not adsorbed when administered, it is believed that the drug may not exhibit any kind of half-life 2.
- Clearance
Psyllium husk when administered as intended largely undergoes little absorption into the body and plasma.

Overdose with psyllium husk can cause abdominal discomfort, flatulence, and/or intestinal obstruction 3.
The LD50 of psyllium husk administered orally to mice has been observed in some studies to occur in doses up to 2940 mg/kg or 3360 mg/kg in rats 5.
