Effectiveness

How Questran Affects Patients

Cholesterol is the main ingredient in bile acids. Bile acids are produced during digestion to help with the breakdown of food in the intestines. Most of the bile acids are then reabsorbed back into the liver. Cholestyramine resin binds to bile acids in the intestine and prevents them from being absorbed. This forces the bile acids to be eliminated in the feces instead.

How Questran works in the body

Cholestyramine works to reduce the amount of bile acids reabsorbed in the gut. It does this by exchanging its chloride anions with bile acids in the gut, creating a resin-like substance that binds to the bile acids and prevents them from being reabsorbed. Cholestyramine is made up of a functional group attached to a copolymer, which helps it bind to the bile acids.

There are 20 known major drug interactions with Questran.

Common Questran Drug Interactions

Drug Name

Risk Level

Description

Mycophenolate mofetil

Major

Cholestyramine may increase the excretion rate of Mycophenolate mofetil which could result in a lower serum level and potentially a reduction in efficacy.

Mycophenolic acid

Major

Cholestyramine may increase the excretion rate of Mycophenolic acid which could result in a lower serum level and potentially a reduction in efficacy.

Raloxifene

Major

Cholestyramine can cause a decrease in the absorption of Raloxifene resulting in a reduced serum concentration and potentially a decrease in efficacy.

(R)-warfarin

Minor

Cholestyramine can cause a decrease in the absorption of (R)-warfarin resulting in a reduced serum concentration and potentially a decrease in efficacy.

(S)-Warfarin

Minor

Cholestyramine can cause a decrease in the absorption of (S)-Warfarin resulting in a reduced serum concentration and potentially a decrease in efficacy.

Questran Toxicity & Overdose Risk

Taking too much of the drug may result in a blockage of the intestines or stomach.

Patient Q&A Section about questran

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

When should you take Questran?

"Adults: 4 grams one to two times a day before meals, then your doctor may increase your dose to 8 to 24 grams a day, divided into two to six doses.

Children: 4 grams a day."

Answered by AI

What are cholestyramine side effects?

"There are many different gastrointestinal issues that can occur, including constipation, bloating, stomach pain, gas, upset stomach, vomiting, diarrhea, and loss of appetite. Each of these can be extremely unpleasant and can have a major impact on your quality of life. If you are experiencing any of these symptoms, it is important to see a doctor so that you can get the proper diagnosis and treatment."

Answered by AI

How does questran work for diarrhea?

"Cholestyramine is a medication that helps lower cholesterol levels and remove excess bile acid from the intestines, which can relieve the symptoms of diarrhea associated with bile acid malabsorption."

Answered by AI

What is the drug questran used for?

"Bile acid-binding resins are a type of medication that work by removing bile acid from the body. In people with high cholesterol, this causes the liver to make more bile acid by using cholesterol in the blood, which helps to lower the cholesterol levels."

VR-Enhanced PMR for Post-Burn Symptoms

18+
All Sexes
Baltimore, MD

The goal of this clinical trial is to learn whether progressive muscle relaxation (PMR), delivered either alone or enhanced with virtual reality (VR), can help treat chronic symptom, such as pain, itch, anxiety, sleep disturbances, and fatigue, in adult burn survivors. The main questions it aims to answer are: * Does VR-enhanced PMR (VR-PMR) reduce chronic pain, anxiety, itch, sleep disturbances, and fatigue more effectively than standard PMR? * Is VR-PMR a feasible and acceptable self-administered home-based intervention for burn survivors? Researchers will compare two self-administered intervention conditions, VR-enhanced PMR and standard PMR, using a randomized to sequence crossover design to see if VR technology enhances the therapeutic effects of PMR on chronic symptom management in burn survivors. Participants will: * Complete home-based sessions of VR-enhanced PMR * Complete home-based sessions of standard PMR * Report symptoms such as pain, itch, anxiety, sleep disturbances, and fatigue throughout the study * Use VR equipment provided for the intervention period (during the VR-PMR arm)

Supportive Care for High Cholesterol

18 - 120
All Sexes
Clark, NJ

Hypercholesterolemia is recognized as the major driver for cardiovascular morbidity and mortality. To help address this in our community, Atlantic Medical Group (AMG) formed a lipid workgroup chaired by Robert D. Fishberg, MD, and Jeffrey N. Feldman, MD. The overarching goal of the lipid workgroup is to enhance the treatment of lipid disorders in those patients with abnormal lipid levels by improving access to resources at the primary care practice level and specialty level. We aim to develop a model for primary and secondary prevention that integrates guidelines for treatment at the practice level. Our primary objective is to identify high-risk patients by utilizing the electronic health record and partnering with patients' primary care providers to provide comprehensive medical management.

Cascade Screening for High Cholesterol

18+
All Sexes
Philadelphia, PA

The goal of this clinical trial is to test two implementation strategies (automated health system \[Penn Medicine\]-mediated strategy vs. Family Heart Foundation-mediated strategy using a patient navigator) versus usual care to promote family cascade screening for familial hypercholesterolemia (FH) in Penn Medicine patients diagnosed with FH ("probands"). The main questions this study aims to answer are: (1) evaluating the effect of the three approaches on reach (proportion of probands who have at least one family member who completes screening), number of family members screened, number of family members diagnosed with FH, and proband LDL-C levels; and (2) identifying implementation strategy mechanisms focusing on health equity using mixed methods and oversampling populations that experience disparities. Participants (probands) in the active arms (health system \[Penn Medicine\]-mediated, Family Heart Foundation-mediated) will receive messaging that provides education about FH and provides instructions for participating in family cascade screening. A subset of probands will be invited to complete a qualitative interview about their experience receiving the implementation strategy. The research team will compare the active arms to Penn Medicine usual care for cascade screening to evaluate whether the active arms are more effective at promoting cascade screening than usual care.

Meal Intake for Atherosclerosis

18 - 95
All Sexes
Saint Louis, MO

High protein low carbohydrate diets have become popular in recent years to help facilitate weight loss. It is controversial if these diets are associated with an increased risk of cardiovascular disease. Recent work in mice has implicated monocytes/macrophages and mTOR signaling as the culprit cell type driving the increased cardiovascular risk with high protein diets. We aim to build on this preclinical research by evaluating the effects of liquid meals with different protein and leucine (a potent mTOR activator) contents on circulating human monocytes and platelets. Study participants will be given either a low protein liquid meal, a high protein liquid meal, or a low protein liquid meal with additional leucine. Blood will be collected from study participants just just prior to and for several hours after ingestion of the meals. Activation of amino acid-dependent signaling pathways (particularly mTOR) and downstream sequelae will be evaluated in the isolated monocytes and platelets.
