We like introduce ourselves as one of the reliable and trusted organizations engaged in offering our clients Pyrimethamine. This derivative is indicated for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy. Pyrimethamine is used with other medications to help prevent nausea and vomiting caused by cancer drug treatment. This medication is also used to prevent nausea and vomiting after surgery. It works by blocking one of the body's natural substances that causes vomiting.
