How does medicine change how your blood is?

Question

I've heard people say that medicine can sometimes change stuff in your blood. How long does it generally take medicine to completely get out of your blood and no longer show up in your blood?

It's all legal drugs. But how would you know which types of medicines would take longer than other medicines?

Answer 1

Different medicines take different times to be removed from your body some taking up to a year. Don't be concerned as long as you're taking legal drugs. Medicines can add to, decrease or increase what's in your blood.

Answer 2

people say that medicine can sometimes change stuff in your blood - yes it is true ... and it is called PharmacoDynamics ... there are many drugs that are given in pro-drug form which then get converted to active drug once inside your body or at an specific site for example the brain ... many drugs properties are used to deliver then to specific sites like for example some drug go especially to the gall bladder or the kidney so when these sites are infected you can use these drugs to act on these sites ....

How long does it generally take medicine to completely get out of your blood and no longer show up in your blood - what you are asking is known as PharmacoKinetics ... well there are many factors which determine the rate of absorption for example the quantity of drug, the route of drug, the specific property of drug like fat solubility, etc which determine its rate of absorption ... once absorption it goes through the blood and does it job and finally gets out of the body via the liver, or kidney or skin or etc ... again many factors depend upon its time of stay in the body like for example the half life (t1/2) of the drug, the volume of distribution and etc ....

pharmacology is vast subject but i hope that ive answered so that you get an idea ...
