Drug Mode of Action ::  

Pyrimethamine is a folic acid antagonist structurally similar to trimethoprim. It inhibits parasitic dihydrofolate reductase, thus inhibiting vital tetrahydrofolic acid synthesis. It is active against pre-erythrocytic forms and is also a slow-acting schizontocide.

Drug Interactions ::

Lorazepam may induce hepatotoxicity. Increased risk of bone marrow suppression when used with agents that have myelosuppressive properties e.g. proguanil, sulfonamides, zidovudine and cytostatic agents. Increased risk of serious pancytopenia and megaloblastic anaemia when used with co-trimoxazole or other sulfonamides.
