Lipid-Lowering Drugs: Statins and Miscellaneous Agents

1.8K
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...

Lipid Absorption

Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Cytomegalovirus Disease

108
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Cholecystitis01:20

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Chylomicronemia induced by cimetidine.

P H Iverius, J D Brunzell

    Gastroenterology
    |September 1, 1985

    Summary

    Cimetidine can trigger chylomicronemia, a condition causing severe pain and organ issues, in individuals with hypertriglyceridemia. This risk necessitates caution when prescribing cimetidine to patients with pre-existing lipid disorders.

    Area of Science:

    • Clinical Pharmacology
    • Gastroenterology
    • Internal Medicine

    Background:

    • Hypertriglyceridemia is a common lipid disorder, often with a genetic predisposition.
    • Cimetidine is a widely used medication for treating peptic ulcers.
    • Patients with hypertriglyceridemia are at increased risk for complications like pancreatitis.

    Observation:

    • A 35-year-old male with moderate hypertriglyceridemia and a family history of hyperlipidemia developed symptoms of chylomicronemia.
    • Symptoms included abdominal pain, myalgia, and splenomegaly during cimetidine treatment for a duodenal ulcer.
    • Discontinuation of cimetidine led to the resolution of chylomicronemia and associated symptoms.

    Findings:

    • Reintroduction of cimetidine after 6 months resulted in the rapid recurrence of chylomicronemia within 6 days.

  • This case demonstrates a direct causal link between cimetidine administration and the induction of chylomicronemia in a susceptible individual.
  • The patient's underlying hypertriglyceridemia was a key factor in this adverse drug reaction.

    • Implications:

    • Clinicians should be aware of the potential for cimetidine to induce chylomicronemia in patients with hypertriglyceridemia.
    • Screening for or awareness of hyperlipidemia may be warranted before initiating cimetidine therapy.
    • Monitoring for symptoms of hypertriglyceridemia is crucial in patients with known lipid disorders receiving cimetidine.
