EDDN,
Sorry must have been having a bad day drinking enough Gin and Tonics to keep up my quinine levels
You're quite correct, Chloroquine is normally traded as Avloclor or Nivaquine, and Proguanil hydrochloride normally trades as Paludrine.
The point I was actually trying to make is that they are only effective together and normally only any use against Plasmodium vivax, ovale and malariae. It has little use in most African countries against P. falciparum. As soggyboxers said, currently the best chemoprophylactics are either Malarone or doxycycline, one causing gastro-intestinal irritation and the other photosensitivity. You take your choice
