Talk:Propylhexedrine

Discussion of base
"Freebase propylhexedrine is a volatile, oily liquid at room temperature. The slow evaporation of freebase propylhexedrine allows it to be administered via inhalation. The evaporation of the freebase also accounts for the limited shelf-life of propylhexedrine inhalers. Many of the salts of propylhexedrine are stable, clear to off-white crystalline substances that readily dissolve in water."

 * The first reference serves to prove that propylhexedrine gradually escapes from an inhaler, which gives a standard nasal inhaler with it as the active ingredient a limited shelf-life. The second indicates that the ingredient is "relatively pure propylhexedrine hydrochloride" which is freebase propylhexedrine. It also demonstrates that the salt was soluble in water. I don't know if there is an indication of the color and solubility of other salts, since it looks like that second reference may be longer than the abstract I can see?

 * The second ref ([33]) (free accessed) links to page 650. It should link to page 359–372. I recommend use this ref   Mongrangvebet (talk) 18:34, 19 May 2024 (UTC)
