drugs get metabolised (broken down) at different rates.
Some drugs are metabolised quickly, therefore have shorter half lives and more frequent dosing to maintain optimal levels.
some drugs take longer and need less dosing.
Other things can also affect half lives

The half-life of the drug is the time taken for the plasma concentration of the drug to reduce to 50% of its original value. Units of half life are hour, minute, or day. The formula for calculation half life of a drug is as follows: Cp is the concentration at time one and Cp/2 is the concentration at time one half-life later:- In( Cp/2) = In Cp - Kel . t1/2 half life of the drug (t 1/2) = 0.693/kel
How long will you go through withdraw from tramadol and is there something over the counter you can take to help?
The answer to this is somewhat complicated. Some of this depends on the dose and the elimination half life. The higher the dose, the longer it will take for your body to eliminate it. This is just common sense. Half-life indicates the amount of time it takes for the body to eliminate half of the remaining dose. After one half life, half of the original amount remains. After two half-lives, one-quarter of the original amount remains and so on. However, you asked about withdrawal. Withdrawal is a complex phenomenon that depends on how long you have been using this medicine and at one dose. All humans build up a tolerance to the effects of this agent. Restated, you will need more and more drug over time to achieve the same effect. The name for this is "tolerance" and it should not be confused with addiction as they are not the same. Tolerance depends on the length of time the drug has been used and the dose. Withdrawal occurs when there is a sudden reduction in the dose. While withdrawal is not dangerous, it is unpleasant. There are medicines to address this problem that you can obtain from your physician. Withdrawal can be minimized by tapering the dosage slowly as well. You should also discuss this with your physician. Do not try to do this on your own. You really need to discuss this with your treating physician.
