2) bisacodyl

3) lactulose

4) docusate

QUES : loperamide, diphenoxylate and codeine inhibit intestinal propulsive motility by :

1) stimulating serotonergic receptors

2) stimulating opiod ( u) receptots

3) stimulating muscarinic receptors

4) blocking opioid (u) receptors

QUES : which of the following are actions of Antidiarrheals? ( select all that apply)

1) increase smooth muscle tone and diminish secretions

2) reduce fluid content of the stool

3) neutralize hydrochloric acid and decrease gastric PH

4) decrease peristalsis and motility of the intestinal tract

5) displace histamine from the receptor site

QUES: ANTISPASMODICS are used to treat which of the following conditions ( select all that apply)

1) Biliary colic

2) pancreatitis

3) hpermotility

4) hyperacidity

5) irritable bowel syndrome

QUES : an example of an osmotic laxative is:

1) bisacodyl

2) lactulose

3) saline laxative

Answer 1

1. Docusate.: It is emollient laxative which is anionic detergent. It lower the surface tension permit water and fatty substance to penetrate and mix with fecal matter.
2. Stimulating the opioid u receptor: The above mentioned drugs are u opioid agonist which stimulate opioid receptor which block the transmission within enteric pathway leads muscle contraction. Ultimately inhibit peristalsis.
3. 1. Increase the smooth muscle tone and diminish secretion.
   2. Reduce fluid content of the stool
   3. Decrease peristalsis and motility of intestinal tract.
4. Antispasmodic are used
   1. Biliary colic
   2. Pancreatitis
   3. Hyper motility
   4. Irritable bowel syndrome

5.Osmotic laxative is lactulose. Lactulose pull the water back in to the stool to soften the stool.
