Why are so many medications something-hydrochloride?

Meaning, is there some metabolic property (for example) of HCl. Or some sort of chemical stabilizer?

Some medicines are organic compounds that are unable to be dissolved in water or acidic solutions (like the environment in your stomach). Whenever you see the hydrochloride, it means the pharmaceutical company has converted the insoluble drug molecule into a hydrochloride salt to increase its water solubility so it can actually be absorbed in the body. Other salts can be made, such as fumarates.
