Oral steroids

Oral Steroids

Oral steroids involve modification of the parent steroid to make it harder for the liver to degrade the steroid molecules. This modification is almost always the addition of an alkyl (methyl) group at the 17 position of the steroid ring. The liver can still degrade the steroid, but not as effectively as the un-modified steroid. Therefore, oral steroids make several cycles through the bloodstream before being excreted. Most oral steroids are, to various degrees, excreted from the body unchanged. Because of this alkyl group prolonged use and high doses can be toxic on the liver.

The most popular oral steroids are
