Note the following: Low-density lipoprotein (LDL) reduction of 25%-60% Examples include Atorvastatin, fluvastatin, lovastatin, pitavastatin, pravastatin, rosuvastatin, simvastatin Contraindications include hypersensitivity, active liver disease, pregnancy, lactation, coadministration with strong CYP3A4 inhibitors (selected statins) Vitamin B3 Vitamin B3 inhibits very-low-density lipoprotein (VLDL) synthesis. Note the following: LDL reduction of 10% High-density lipoprotein (HDL) increase of 20% Example includes Niacin (nicotinic acid) Contraindications include hypersensitivity, liver disease, active peptic ulcer, severe hypotension, arterial bleeding Fibrates Fibrates enhance lipoprotein lipase, resulting in increased VLDL catabolism, fatty acid oxidation, and triglycerides elimination. They decrease hepatic extraction of free fatty acids.

Vaughn Bell once called it the Kim Kardashian of molecules, but I don’t think that’s fair to dopamine. Suffice it to say, dopamine’s big. And every week or so, you’ll see a new article come out all about dopamine. https://www.medicalvideos.com/watch/sensitivity-and-specificity_ad5f1309b31c56e2d5a8.html Wed, 17 Jan 2024 05:32:08 +0000 https://www.medicalvideos.com/watch/sensitivity-and-specificity_ad5f1309b31c56e2d5a8.html Easily understand the concepts of SENSITIVITY and SPECIFICITY!

Angiotensin converting enzyme (ACE) inhibitors are agents used to relax blood vessels and lower blood pressure. They prevent an enzyme from producing angiotensin II, which narrows blood vessels and raises blood pressure, meaning the heart has to work harder to pump blood around the body. https://www.medicalvideos.com/watch/statins-fibrates-niacin_ceeff3c2dced65ed63ee.html Wed, 17 Jan 2024 05:32:08 +0000 https://www.medicalvideos.com/watch/statins-fibrates-niacin_ceeff3c2dced65ed63ee.html This animated video covers statins, fibrates, niacin, bile resins, and ezetimibe.

The development of new drugs and an understanding of how best to use them and the older drugs have significantly improved the quality of life of people with the disease. There are two general approaches to the treatment of Parkinson's disease with medication. The first approach attempts to increase the levels of dopamine in the brain and the second approach attempts to improve the symptoms of Parkinson's disease by other means. Most patients with Parkinson's disease can initially be treated with drugs that adequately alleviate their symptoms. If or when medications are not sufficiently effective, new, highly effective and safe surgical treatments are also available.
