Psyllium is known as this type of laxative.

What is 1 to 3 hours?

This class of drugs reduces gastric acid production by blocking the proton pump in parietal cells of the stomach
What are proton pump inhibitors (PPIs)
This specific drug works by binding to opioid receptors in the GI tract to slow motility and relieve diarrhea.
What is loperamide (Imodium)?
A common side effect of this drug is tachycardia, dizziness, headache, flushing, nausea and vomiting
What is Imodium? (OPIATE-RELATED ANTIDIARRHEAL AGENTS)
