Can someone explain the definition of 1/2 life to me? A clear, simplified answer? I am not a simple person, but more of a visual learner. So, when it's broken down for me in language, I can break it down in my brain and 'see' to understand what I'm reading. Make sense? Hopefully? @lemonhead ~ no making fun of the new kid! :P
Hello Jillynnie. I can answer that for you. A half life is how long a drug, when taken, it takes your body to break down that drug, retain in in your body, and then leave your body. Some medications can stay in your blood system, often say a week. Another from the time thats its taken, might leave your body within the same day you took it. A short halflife, taken is just that. The drug effectively works for a short period of time. A long halflife, means it will stay within your body for days, often a week, even longer. Hope this helps. I'm not a chemist either. :-0)
Just wanted to say thank you for asking this question. The term "half-life" can be very misleading and confusing and was to me also in the same way it was to you when I first started learning about medicine... it refers to biological half-life of a drug or medicine which is basically how long it takes for a drug to reduce to half its pharmacological activity (half its effect).
Here's a link for you to read that I think is helpful and explanatory. Happy Holidays!
