Maxillary Artery Branches. The Buccal artery is a small artery of the head and a branch of the second part of the maxillary artery (the 7th branch of the external carotid) and supplies both the buccinator muscle and cheek. The maxillary artery (the 7th branch of the external carotid) gives off an infraorbital artery.
For high cholesterol, 300-1,2000 milligrams of niacin has been taken by mouth daily for 6-44 weeks as wax-matrix, immediate-release (crystalline); 2 grams of niacin has been injected into the vein over 11 hours. The maximum recommended daily dose is 3 grams.
The recommended dietary allowance (RDA) of this vitamin is 14 to 16 mg daily in adults, and slightly more for pregnant women (18 mg) and less for children (2 to 12 mg). Niacin given at or around these doses is not associated with significant side effects or liver injury. Niacin is a component of most multivitamin and vitamin B preparations in concentrations close to the minimum daily requirement, which are not effective in lowering lipid levels.
