what i mean is there are some that are absorbed through the skin, like motion sickness medication. so if that can be absorbed through the skin, cant all medicines be too??
(sources would be nice too)

The source below should answer your question:
All medicines are designed to be absorbed by the bloodstream, into the body. Some are taken orally, to be absorbed by the intestines - and from there into the blood stream. Other medicine is applied topically, in ointment form, to be absorbed by the skin and from there into the bloodstream.
Some mediciness are administered DIRECTLY into the bloodstream by syringe or tube.
Even others are administered through INHALATION, like asthma inhalers, the medicine is absorbed into the lungs and transported into the blood stream.
Medicine would not function, if it could not be absorbed by the body.

Medicine that is oral (taken through the mouth) works by being absorbed into the blood stream. At the bottom of the stomach is the pyloric valve that lets chyme (what you eat when digestive enzymes are added to it in your stomach). This valve opens when the chyme has been softened and is ready for absorption. Once in the duodenum (past the stomach), the food or medicine starts to be absorbed. But not all medicine is absorbed. Calcium for instance is very hard for most women to absorb. Vitamin B-12 is also hard to absorb (so many people take vitamin B-12 shots).
There is a term called isotonic. That means "same as", and in this case means same as blood plasma. If something is isotonic it will pass through the cell walls and go directly into the blood stream. DMSO is one substance that does this. If you rub it on your wrist, you get a very funny taste on your tongue very quickly.
What is a drug-food interaction?
A drug-food interaction happens when the food you eat affects the ingredients in a medicine you are taking so the medicine can't work the way it should.
Drug-food interactions can happen with both prescription and over-the-counter medicines, including antacids, vitamins and iron pills.
Are all medicines affected by food?
Not all medicines are affected by food, but many medicines can be affected by what you eat and when you eat it. For example, taking some medicines at the same time that you eat may interfere with the way your stomach and intestines absorb the medicine. The food may delay or decrease the absorption of the drug. This is why some medicines should be taken on an empty stomach (1 hour before eating or 2 hours after eating).
On the other hand, some medicines are easier to tolerate when taken with food. Ask your doctor or your pharmacist whether it's OK to take your medicine with a snack or a meal or whether it should be taken on an empty stomach.
