Treatment Summary

Loperamide is a medication used to treat diarrhea. It works by blocking the release of certain chemicals in the gut, which reduces the amount of fluid in the stool. It does not get absorbed into the body, so it does not affect the central nervous system or adrenal glands, but it does block histamine and interrupt the release of acetylcholine in the stomach.

How Loperamide Hydrochloride Affects Patients

Loperamide is an anti-diarrheal medication that helps relieve diarrhea. It helps reduce the speed of digestion and encourages the body to absorb more fluid and electrolytes from the digestive system. It also tightens the anal sphincter, which helps reduce incontinence and sudden urges to go to the bathroom. The effects of loperamide usually start within an hour and can last up to three days. Although it is a potent mu-opioid receptor agonist, it does not usually provide pain relief. Taking large amounts of loperamide can interfere with how the heart works, which can cause irregular heartbe

How Loperamide Hydrochloride works in the body

Loperamide is a drug that helps manage gastrointestinal issues. It works by binding to opioids receptors on the circular and longitudinal muscles of the intestine. This binding activates certain pathways which reduce nerve activity in the gut, decreasing the release of neurotransmitters and other molecules. This leads to decreased peristalsis, which slows down the movement of food through the gut. Loperamide also helps with the absorption of water and electrolytes, and can lead to firmer stools.

Loperamide Hydrochloride Toxicity & Overdose Risk

The toxic dose of loperamide in rats is 185 mg/kg. Taking too much loperamide can cause serious heart problems, such as an irregular heartbeat, or sudden death. It can also lead to symptoms of opioid toxicity, like confusion, sleepiness, pinpoint pupils, stiff muscles, shallow breathing, and a blocked intestine. If you suspect an overdose, medical treatment may include naloxone to reverse the toxic effects.

Loperamide Hydrochloride for Diarrhea

Get a prescription from your doctor so you can buy it in bulk; 100 count bottles. Insurance companies will cover the cost this way. The drug is effective at masking symptoms, but I want to get to the root of the issue and eliminate it altogether. This might be connected to the surgery I had in California over three years ago, but nobody seems to know for sure.

Patient Q&A Section about loperamide hydrochloride

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What are side effects of loperamide?

"The following are symptoms of a bad reaction to a medication: blistering, peeling, or loosening of skin; chest pain or discomfort; decrease in urine volume; decrease in frequency of urination; difficulty in passing urine; fast, pounding, or irregular heartbeat or pulse; hives or welts; itching; rash; or irregular or slow heartbeat."

Answered by AI

What does loperamide hydrochloride do?

"Loperamide is a medicine used to treat diarrhoea by making the stool firmer. It can help with short-term diarrhoea or irritable bowel syndrome (IBS) by decreasing the number of bowel movements and making the stool less watery. Loperamide is also used for recurring or longer lasting diarrhoea from bowel conditions such as Crohn's disease, ulcerative colitis and short bowel syndrome. It works by slowing down the movement of the intestine so that the body can absorb more water from the stool."

Answered by AI

Why is loperamide not recommended?

"This medicine could lead to heart rhythm problems, such as torsades de pointes, ventricular arrhythmias. If you or your child have chest pain or discomfort, a fast, slow, or irregular heartbeat, fainting, or trouble breathing, check with your doctor right away. Loperamide may raise your chances for stomach or bowel problems."

Answered by AI

When is the best time to take loperamide?

"Adults and teenagers should take 4 mg (2 tablets) after the first loose bowel movement, and 2 mg (1 tablet) after each loose bowel movement after the first dose has been taken. No more than 8 mg (4 tablets) should be taken in any 24-hour period."

Nutritional Therapy + Anti-TNFα for Crohn's Disease

All Sexes
Vancouver, Canada

Children with Crohn's disease (CD), a type of Inflammatory Bowel Disease (IBD), often face serious health challenges, including poor growth, frequent hospital stays, and long-term medication use. Although biologic drugs like infliximab, an anti-TNFα (Tumor necrosis factor α) medication, have improved treatment, they don't work for everyone: many children still experience symptoms or disease flare-ups. Nutritional therapies, especially the Crohn's Disease Exclusion Diet (CDED), may help improve treatment outcomes. This study will assess whether starting CDED at the same time as infliximab leads to better responses to treatment. The goal of this study is to improve how well children respond to therapy, reduce drug exposure, and support better long-term health.

MITI-001 for Irritable Bowel Syndrome

18 - 65
All Sexes
Redwood City, CA

While the pathophysiology of diarrhea-predominant irritable bowel syndrome (IBS-D) is complex and heterogeneous, dysbiosis of the gut microbiome is frequently observed, suggesting that a substantial subset of patients with irritable bowel syndrome (IBS) have symptoms that are initiated and/or perpetuated by a microbiome dysfunction. Successful randomized controlled trials (RCT) for IBS-D (Ford 2018; Black 2022) leveraging microbiome-targeted therapies (antibiotics or low microbiome fermentation diets) suggest the gut microbiome is at least partially involved in IBS symptoms. Furthermore, fecal microbiota transplantation (FMT) for patients with IBS-D has demonstrated promising results (El-Salhy 2020), supporting the possibility that altering the microbiome composition could ameliorate IBS-D symptoms. MITI-001 is a transplantable gut bacterial community composed of 157 live bacterial strains, encompassing 79 genera of commensal bacteria, that have been isolated from healthy donor stool, purified, and banked. The hypothesis of the proposed research is that MITI-001 can target the pathophysiologic lesion in a subset of IBS-D patients, restore the altered microbial metabolic process, and thus alleviate IBS-D symptoms.

The goal of this trial is to learn if an interactive evidence-based educational outreach visits to clinicians who prescribe biologics change prescribing of biosimilar medications. The main questions it aims to answer are: 1. Do educational outreach visits lead to a higher number of prescriptions for biosimilar versions of adalimumab? 2. Do in-person or virtual visits work better? Researchers will compare clinicians offered the educational outreach visit to those who are not offered the visit to see if there is a difference in prescribing of biosimilar versions of adalimumab instead of the original brand-name version. Participants will be offered the chance to meet with a trained clinician who will provide educational information tailored to their knowledge and attitudes on the topic. They will also be provided an educational brochure and patient educational materials.

Morning Light Therapy for Inflammatory Bowel Disease

All Sexes
New York, NY

The pilot study will focus on the effects of morning light therapy (MLT) in adult patients with ulcerative colitis (UC) who have evidence of poor sleep quality and active inflammation. The specific population is at risk for circadian rhythm sleep-wake disorders and has significant potential benefit from circadian realignment, which may lead to improved sleep quality and, ultimately, UC-related inflammatory activity. During an initial one-week lead-in period, participants will obtain baseline circadian-related labs, complete symptom-related surveys, and use a wearable device continuously to obtain baseline sleep-wake data. After the lead-in week, patients will undergo one hour of MLT while wearing wearable devices continuously and completing daily symptom surveys. At the end of four weeks of MLT, patients will obtain post-intervention circadian and inflammatory assessments in addition to completing the same symptom-related surveys.

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are chronic inflammatory conditions of the gastrointestinal tract that affect millions of people in the United States of America. Among patients with IBD, symptomatic flares are quite common; up to 40-50% of patients in some populations report having a flare at least once per month. For most patients with IBD flares, the typical outpatient treatment consists of corticosteroids and, in some instances, initiation of or switching between 5-aminosalicylic acid-acid preparations, immunomodulators, or biologics. These treatments, while often effective, can have harmful side effects, especially when used for long durations of time. Therefore, alternative treatments are highly sought after by both patients and providers.
