Cholestyramine: an effective, twice-daily dosage regimen
Annals of Internal Medicine
|September 1, 1976
Summary
Cholestyramine effectively lowers plasma cholesterol in familial hypercholesterolemia patients. A twice-daily dosage is as effective as a four-times-daily regimen, potentially improving treatment adherence.
Area of Science:
- Biochemistry
- Pharmacology
- Clinical Medicine
Background:
- Familial hypercholesterolemia (FH) is a genetic disorder characterized by high plasma cholesterol levels.
- Type II hyperlipoproteinemia is a common form of FH, increasing cardiovascular disease risk.
- Effective cholesterol-lowering agents are crucial for managing FH patients.
Purpose of the Study:
- To compare the efficacy of twice-daily versus four-times-daily cholestyramine dosage in lowering plasma cholesterol.
- To assess the impact of dosage frequency on treatment adherence in patients with familial hypercholesterolemia.
Main Methods:
- A comparative study involving nine FH patients and two healthy volunteers.
- Administration of cholestyramine with two different dosage frequencies (twice-daily vs. four-times-daily) using the same total daily dose.
- Monitoring of plasma cholesterol levels to evaluate treatment effectiveness.
Main Results:
- Both twice-daily and four-times-daily cholestyramine regimens demonstrated equal effectiveness in reducing plasma cholesterol levels.
- The study suggests that a simplified twice-daily dosage can achieve comparable therapeutic outcomes.
Conclusions:
- Twice-daily cholestyramine administration is an equally effective alternative to a four-times-daily regimen for lowering plasma cholesterol in FH patients.
- Simplifying the cholestyramine dosage schedule to twice daily may significantly improve patient adherence and treatment compliance, particularly for working adults and children.

Dosage Regimen: Fixed Dose
Fixed-dose regimens are a common approach to administer drugs to achieve and maintain desired levels of the drug in the body. In this dosing strategy, a specific amount of medication is given at regular intervals, often multiple times a day, to ensure a consistent drug concentration in the bloodstream.
Fixed-dose regimens can be used for various routes of administration, including intravenous (IV) injections and oral medications. For IV administration, a predetermined amount of the drug is...

Lipid-Lowering Drugs: Statins and Miscellaneous Agents
Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...
Drugs for Treatment of Constipation-Predominant IBS
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
Cholesterol: Significance and Regulation
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.

Hepatic Drug Excretion: Enterohepatic Cycling
Enterohepatic cycling involves the active secretion of drugs and their metabolites into the bile via transporters in the canalicular membrane of hepatocytes. This secretion is an integral part of the digestive process, releasing these substances into the gastrointestinal (GI) tract.
Post-release drugs and metabolites can be reabsorbed into the body from the intestine. For conjugated metabolites like glucuronides, reabsorption requires enzymatic hydrolysis by intestinal microflora. This...

Atherosclerosis III: Management
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
