Questran vs Bentyl
Introduction
Patients suffering from gastrointestinal disorders such as Irritable Bowel Syndrome (IBS) or high cholesterol often need medications that can manage their symptoms and improve the quality of life. Questran and Bentyl are two drugs frequently prescribed for these conditions. Both have different mechanisms of action but contribute to alleviating digestive discomforts in patients. Questran, also known as cholestyramine, is a bile acid sequestrant that works by reducing cholesterol levels in the blood by binding to bile acids in your intestines and preventing their absorption. On the other hand, Bentyl or dicyclomine acts on muscarinic acetylcholine receptors primarily found within smooth muscle tissue of the gut, thereby relieving spasms associated with IBS.
What is Questran?
Cholestyramine (the generic name for Questran) was one of the first bile acid sequestrants to be approved by the FDA in 1973. This drug works by binding to certain substances in the intestine, helping remove cholesterol from the body, making it valuable for lowering high cholesterol levels. On another note, Dicyclomine (with Bentyl as a brand name), falls under a class of drugs known as antispasmodics and is primarily used for treating symptoms associated with irritable bowel syndrome (IBS). Approved by the FDA in 1950, it works mainly by blocking acetylcholine activity on smooth muscles and glandular cells in your gastrointestinal tract. While both serve different functions — Questran focusing on reducing cholesterol levels while Bentyl targets gastrointestinal issues — they symbolize great advancements within their respective areas of treatment.
What conditions is Questran approved to treat?
Questran has been approved for the management of several medical conditions, including:
- Reduction in serum and LDL cholesterol levels in patients with primary hypercholesterolemia
- Relief of pruritus associated with partial biliary obstruction
- Postoperative control of increased bile flow in patients who have undergone ileal resection.
How does Questran help with these illnesses?
Questran helps to manage high cholesterol by limiting the amount of bile acids available in your intestines. It does this by binding to the bile acids, forming a complex that is excreted from your body. Bile acids are substances produced by your liver that play an important role in digestion and absorption of fats in your small intestine. When levels of these acids decrease, because they are being excreted along with Questran, the liver compensates by converting more cholesterol into bile acids which results in lower blood cholesterol levels.
On the other hand, Bentyl plays a different role as it manages irritable bowel syndrome (IBS) symptoms such as stomach cramping or bloating. It works on smooth muscle tissue present throughout our bodies but particularly within our digestive tract. By blocking acetylcholine - a neurotransmitter responsible for causing muscles contraction - Bentyl can reduce spasms in gastrointestinal tract hence relieving discomfort associated with IBS.
What is Bentyl?
Bentyl, which is a brand name for dicyclomine, is an anticholinergic medication that acts as a smooth muscle relaxant, commonly used to treat symptoms of irritable bowel syndrome (IBS). It works by blocking the action of acetylcholine at muscarinic receptors in the gastrointestinal tract. This results in decreased contraction and spasms of stomach and intestinal muscles. Bentyl was first approved by the FDA in 1950. As dicyclomine does not bind to or inhibit enzymes involved in cholesterol synthesis and transport like Questran does, its side-effect profile differs significantly from that drug's. Notably, it can cause dry mouth, blurred vision, heart palpitations and urinary retention due to its systemic anticholinergic effects - common side effects not typically seen with Questran use. The benefits on gut motility offered by Bentyl can be particularly beneficial for patients suffering from IBS who have not found satisfactory relief using other treatments such as bile acid sequestrants like Questran.
What conditions is Bentyl approved to treat?
Bentyl, also known as dicyclomine, is a medication that's approved by the FDA for the treatment of:
- Irritable bowel syndrome (IBS)
- Other functional conditions related to the gastrointestinal tract
Its primary function is to reduce symptoms such as stomach cramps and spasms in patients who suffer from these conditions.
How does Bentyl help with these illnesses?
Bentyl is a medication that acts by blocking the action of acetylcholine, a neurotransmitter involved in the transmission of nerve impulses. Acetylcholine plays roles in many processes in the body, including muscle contraction and relaxation, and digestive system function. By reducing its activity, Bentyl can alleviate symptoms associated with Irritable Bowel Syndrome (IBS), such as abdominal pain and spasms. The action on acetylcholine may also result in side effects like dry mouth or blurred vision due to reduced bodily secretions. Compared to Questran which works primarily by binding bile acids in your intestines to form a product that is removed from the body, Bentyl provides direct relief for muscle spasms within the gastrointestinal tract which often characterizes IBS conditions. It's usually prescribed when patients do not respond adequately to other forms of treatment or alongside them for optimal results.
How effective are both Questran and Bentyl?
Both cholestyramine (Questran) and dicyclomine (Bentyl) are commonly prescribed medications, but they treat significantly different conditions. Cholestyramine is a bile acid sequestrant that was approved by the FDA in 1973 for reducing high levels of cholesterol in the blood, whereas dicyclomine is an antispasmodic and anticholinergic agent that was approved by the FDA in 1950 to treat irritable bowel syndrome.
The effectiveness of both drugs has been well studied over time. A double-blind clinical trial conducted in 1984 showed that cholestyramine effectively lowered LDL cholesterol levels, thus reducing risks associated with heart disease. Dicyclomine's efficacy was highlighted in a randomized controlled trial from 1998 which demonstrated its significant benefits for patients suffering from irritable bowel syndrome symptoms including abdominal pain and diarrhea.
A comprehensive review published in 2007 reaffirmed cholestyramine's role as an effective primary or supplementary treatment for hypercholesterolemia. Despite having some side effects such as constipation or bloating, it is generally well-tolerated among adults and can be especially beneficial when used alongside dietary modifications.
On the other hand, dicyclomine continues to be considered one of the first-line treatments for managing symptoms related to irritable bowel syndrome due to its proven efficacy and safety profile despite potential side effects such as dry mouth or blurred vision. It works optimally at doses around 20-40 mg four times daily providing considerable relief from gut muscle spasms.
In summary, while these two medicines have very distinct uses - Questran primarily for lowering high cholesterol levels and Bentyl mainly utilized for easing IBS-related discomfort - their established histories attest to their value within their respective fields.
At what dose is Questran typically prescribed?
Oral dosages of Questran range from 1-8 packets/day, but studies have suggested that 2 packets/day are sufficient for managing high cholesterol levels in most people. Adolescents may be started on a lower dosage depending on their weight and overall health condition. In either population, the dosage can be increased after a few weeks if there is no improvement or response to initial treatment. However, it's important not to exceed the maximum dose of 8 packets/day.
On the other hand, Bentyl is typically prescribed at an initial dose of 20 mg taken four times per day (80 mg/day total). This can be reduced based on patient response and tolerability; some patients respond well to as little as 10-20 mg per day. The maximum daily dose should not exceed 160 mg under any circumstances.

Contraindications for Questran and Bentyl?
Questran and Bentyl, like many other medications, may exacerbate certain symptoms or adverse effects in some individuals. If you notice any severe side effects or an increase in discomfort after starting these medications, please seek immediate medical attention.
Neither Questran nor Bentyl should be taken if you are taking certain types of medication. For instance, Questran can interfere with the absorption of a wide range of drugs including heart medicines (like digoxin), certain anticoagulants (like warfarin) and thyroid hormones — so you must always inform your physician about which medications you're taking prior to starting on Questran. As for Bentyl, it's contraindicated for patients with conditions such as myasthenia gravis or glaucoma and those who have trouble urinating due to an enlarged prostate.
Always consult with your doctor before beginning either treatment; they will need to review all current medications and health history to prevent dangerous drug interactions or complications from existing health conditions.
How much do Questran and Bentyl cost?
For the brand name versions of these drugs:
- The price of 60 packets of Questran (4g each) averages around $200, which works out to about $3.33 per day.
- The price for 30 capsules of Bentyl (10 mg) is approximately $130, working out to roughly $4.33/day.
Thus, if you're taking one packet per day as a typical dose for Questran, it could be less expensive on a per-day treatment basis than Bentyl. However, cost should not be your primary consideration in determining which drug is right for you.

As always though, keep in mind that individual needs vary widely so consultation with a healthcare provider is essential when choosing medication options.
Popularity of Questran and Bentyl
Cholestyramine, available under the brand name Questran, was estimated to have been prescribed to about 1.2 million people in the US in 2020. Cholestyramine is used primarily for reducing high levels of cholesterol in patients who are at risk of heart disease and cannot control their levels by diet alone. It works by binding with certain substances in your intestines which carry cholesterol into your body, thus helping excrete them out before they can be absorbed.
Dicyclomine, including brand versions such as Bentyl, was prescribed to approximately 3 million people in the USA during that same year. This medication is an antispasmodic drug used for treating symptoms of irritable bowel syndrome (IBS). Dicyclomine functions by relieving spasms or cramping within the muscles of your stomach and intestines.
While both medications treat different conditions and work on separate mechanisms within the body, it's worth noting that they are essential contributors towards improving patient quality of life when dealing with chronic conditions like hypercholesterolemia and IBS respectively.
Conclusion
Both Questran (cholestyramine) and Bentyl (dicyclomine) have established records of use in patients with gastrointestinal issues, backed by numerous clinical studies indicating their efficacy over placebo treatments. Due to their differing mechanisms of action, they are prescribed under different circumstances. Questran is primarily used for reducing high levels of cholesterol in the blood or relieving itching caused by blockage in the bile ducts of the gallbladder while Bentyl acts as an antispasmodic to treat irritable bowel syndrome.
In some cases, these medications may be combined depending on a patient's specific health needs but this decision requires careful consideration by a physician due to potential contraindications between them.
Questran and Bentyl are both available as generics representing significant cost savings especially for those paying out-of-pocket. Both drugs might require an adjustment period where effects may not be immediately noticeable.
The side effect profile differs between these two medications; common side effects of Questran include constipation and bloating whereas dizziness, dry mouth, blurred vision, nausea are frequently observed with Bentyl usage. Both drugs need close monitoring when starting treatment; any new adverse symptoms should warrant immediate medical attention.
