How does the drug work in the colon

How does the drug work in the colon
Submitted: 2 years ago.

Hello, this is Dr. David. I have read your question and I'm ready to help.
sounds like you have been taking laxatives.
laxatives like senokott and ducolax and miralax pull water from your blood system into your colon to help start to move your bowels when you are very constipated .
if you are dehydrated and not drinking enough water, there will not be enough water in your blood system to go into your colon to help move your bowels
so you have to make sure you drink lots of water and fluids and gadorade or chicken broth or juice to help these medications pull water into your colon so you can fix your constipation.
also using Fleet enemas and Fleet suppositories can help get your stools to start moving from below as well if you are very constipated.
you might need a doctor or nurse to help with finger dis-impaction to help get your stools to start to move
let me know if you have questions.

Thank you Dr David. I was really wanting to know the efficacy of the Amitiza before I call my Primary physcian for Rx. I have been sick for a while now and on lots of meds a R.N to Boost and I lucked out getting a Onc. (. No disrespect ) I just had my chemo on Friday will Amitiza interfere with that
Expert:  Dr. David replied 2 years ago.
I see
Amitiza or lubiprostone activates CIC-2 chloride channels which increase intestinal fluid secretion and motility
what chemo have you been getting.
you have to make sure you are not dehydrated from your chemotherapy.
anti-nausea medications like zofran often will cause constipation.
what chemo are you getting?
Customer: replied 2 years ago.

Have you been approved to prescribed to dispense Myurvanic. I think I didn't spell that correctly My Dr's can't prescribe yet. I think that will bea God send
Expert:  Dr. David replied 2 years ago.
you are welcome
Linzess or lanaclotide is another option to help fight constipation.
you can use lactulose as well
I'm not sure what "Myurvanic" is
