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.
High doses of niacin can cause liver toxicity; doses in excess of 3 grams a day should be used only under careful medical supervision (for example, in the treatment of high cholesterol). Gout, abnormal heart rhythms and worsening of stomach ulcers have also been reported with very high doses of supplemental vitamin B3.
