The skin produces oils and has a epidermis layer which is a membrane of two fatty acids touching at their hyrophilic heads. The lipid(fat) portion is on the outside. If the chemicals of the drug are not fat soluble, then the drug cannot penetrate the nonpolar membrane. Nonpolar substances are usually only soluble in nonpolar solutions and the same goes with polar substances. When a polar substance contacts the skin, the nonpolar part of the fatty acid prevents it from being exocitosisized and it wont enter but rather just sit there on the outside.
1) The skin produces oil. Fat-soluble drugs use this oil as a medium of transfer to move to the skin (from the medicinal skin-patch).
2) Under the skin, the body has a layer of fat. Fat-soluble drugs are able to be absorbed into it and through it.
one is not more desirable than the other. the body requires both water-soluble & fat- soluble vitamins to function properly.

It can be compounded in that way, yes
Medications that are inhalants are delivered through the nose and have effects on the respiratory system. These can be things such as oxygen or drugs for decongestion.
These drugs are preferably delivered in the central line as they may damage peripheral veins. The blood flow is higher in central veins and it can hence dilute the drug's irritating effect, reducing the damage to the vein.
Doing so might calm a baby because ethanol can be absorbed transdermally.

Answer is D. wholesaler
A combination of inhaled anesthetic gases and intravenous drugs are usually delivered during general anesthesia; this practice is called balanced anesthesia.
YES! I found this answer in my A&P book finally and yes it must be lipid-soluble to penetrate the skin.
