| The condition responds well if treatment is started early, and a combination of sulphadiazine and pyrimethamine is the treatment of choice. |
| Several other drugs have been evaluated, including tetracycline, primaquine, sulfadiazine and pyrimethamine. |
| Induced cross resistance to other drugs, like sulfadoxine and pyrimethamine, an antimalarial treatment, is a major concern. |
| Small colony mutants 540 and a subclone of 540 were obtained from cells exposed to pyrimethamine. |
| Chloroquine diphosphate, mefloquine, quinine, and pyrimethamine were obtained from Sigma-Aldrich. |
| Pyrimethamine and sulfadiazine generally are used to treat infants with congenital toxoplasmosis. |
