Antiparasitics
Malaria, protozoa and worms — the drugs for humanity's oldest infections.
Antimalarial Drugs: Hitting a Parasite That Changes Address
Malaria kills hundreds of thousands of people a year, and treating it means chasing a parasite that keeps moving house — from the liver, to the blood, and sometimes into a dormant hideout that reawakens months later. Each drug is built to strike a particular address. Learn where the parasite lives at each stage, and the whole antimalarial toolkit makes sense.
Antiprotozoal Drugs: Beyond Malaria
Malaria gets the headlines, but a whole family of single-celled parasites causes diarrhoea, vaginal and gut infections, and serious tropical diseases. The good news: a handful of familiar drugs — led by one you already know from anaerobic bacteria — covers most of what you'll meet in practice.
Anthelmintics: Drugs That Deworm
Worm infections affect more than a billion people — mostly through the gut, and mostly treatable with a single dose. The drugs work by a beautifully simple idea: paralyse the worm so the body can expel it. Two names cover most of what you'll ever prescribe.
