These are the main classes of antibiotics. Most antibiotics have 2 names, the trade or brand name, created by the drug company that manufactures the drug, and a generic name, based on the antibiotic's chemical structure or chemical class. Trade names such as Keflex and Zithromax are capitalized.
Barbiturates such as Phenobarbitol or Phenobarbitone can cause depletion of calcium, folic acid, vitamin D, vitamin K, and biotin. Phenytoin such as Dilantin can deplete a wide range of nutrients including biotin, calcium, folic acid, vitamin B1, vitamin B12, vitamin D and vitamin K.
Anti-vitamins are chemical compounds that inhibit the absorption or actions of vitamins. For example, avidin is a protein in egg whites that inhibits the absorption of biotin. Pyrithiamine is similar to thiamine, vitamin B1, and inhibits the enzymes that use thiamine.itamins have diverse biochemical functions. Some, such as vitamin D, have hormone-like functions as regulators of mineral metabolism, or regulators of cell and tissue growth and differentiation (such as some forms of vitamin A).
