  1. Caffeine Afsar fathima m.pharm

  2. The word "caffeine" came from the German word kaffee and the French word café, each meaning coffee.

  3. After ingesting caffeine, it is completely absorbed within 30 to 45 minutes, and its effects substantially diminish within about three hours. It is eventually excreted so there is no accumulation in the body.

  4. Caffeine has been shown to affect mood, stamina, the cerebral vascular system, and gastric and colonic activity. But caffeine may not be for everyone.

  5. Caffeine has been called the most popular drug in the world. It is found naturally in over 60 plants including the coffee bean, tea leaf, kola nut and cacao pod. All over the world people consume caffeine on a daily basis in coffee, tea, cocoa, chocolate, some soft drinks, and some drugs.

  6. Caffeine is in tea, coffee, chocolate, many soft drinks, and pain relievers and other over-the-counter medications. In its natural form, caffeine tastes very bitter. But most caffeinated drinks have gone through enough processing to camouflage the bitter taste.

  7. Higher doses of caffeine can cause anxiety, dizziness, headaches, and the jitters. Caffeine can also interfere with normal sleep.

  8. Caffeine also may cause the body to lose calcium, and that can lead to bone loss over time. Drinking caffeine-containing soft drinks and coffee instead of milk can have an even greater impact on bone density and the risk of developing osteoporosis .

  9. Caffeine can aggravate certain heart problems. It also may interact with some medicines or supplements. If you are stressed or anxious, caffeine can make these feelings worse.

  10. Although caffeine is sometimes used to treat migraine headaches, it can make headaches worse for some people.

  11. Caffeine is usually thought to be safe in moderate amounts. Experts consider 200–300 mg of caffeine a day to be a moderate amount for adults. But consuming as little as 100 mg of caffeine a day can lead a person to become "dependent" on caffeine.

  12. This means that someone may develop withdrawal symptoms (like tiredness, irritability, and headaches) if he or she quits caffeine suddenly.
