Comprehensive Guide to FDA-Approved Drugs Used in Dentistry
This extensive guide covers a wide array of FDA-approved drugs commonly used in dentistry, including antibiotics, antifungals, antivirals, analgesics, anti-inflammatory drugs, and various other medications. The aim is to provide dental professionals with a detailed reference to enhance their clinical practice and optimize patient care.
1. Antibiotics
Antibiotics are essential in managing bacterial infections in dentistry. They are prescribed based on the type of infection, patient history, and potential drug interactions.
1.1 Infective Endocarditis Prophylaxis
Infective endocarditis (IE) is a serious infection of the heart valves or lining. Certain dental procedures can cause transient bacteremia, increasing the risk of IE in susceptible patients. The American Heart Association (AHA) recommends antibiotic prophylaxis for patients at high risk of adverse outcomes from IE, such as those with:
- Prosthetic cardiac valves
- History of infective endocarditis
- Certain congenital heart diseases
- Heart transplant with valve regurgitation
Recommended Antibiotics:
