What's the difference between Ritalin, Ritalin LA and Ritalin SR?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

M$The Ritalin LA has long term duration in the body and stays effective or active for about eight to twelve hours (8-12 hours). It is usually taken only once a day and the pill or caplet must be swallowed whole with or without water, but cannot be sprinkled on food.
The Ritalin SR is an intermediate extended release form of the drug, methylphenidate, with a duration of three to eight hours in the body. After the time elapse, it becomes ineffective. It should also be taken whole, without breaking or crushing.
The ordinary Ritalin is an immediate release form and can be crushed and sprinkled on food. It has a short duration in the blood and is effective for about 3-5 hours.
