The Uses of Amprolium

Definition

ChEBI: An organic chloride salt having 1-[(4-amino-2-propylpyrimidin-5-yl)methyl]-2-methylpyridin-1-ium as the counterion. Used for prevention of coccidiosis in poultry and cattle.

Manufacturing Process

1.9 grams of p-toluene sulfonyl chloride was added gradually with shaking to a cooled (0-5°C) solution of 1.67 grams of 2-n-propyl-4-amino-5-hydroxymethyl pyrimidine in 10 ml of 2-methylpyridine. The reaction mixture, after standing three hours in an ice bath, and 15 hours at room temperature, was evaporated to dryness in vacuo. The residue was dissolved in 20 ml of water, acidified with hydrochloric acid and poured over a column of Amberlite IRA- 400 ion exchange resin on the chloride cycle. The eluate was evaporated to dryness to give a residue of 1-(2-n-propyl-4-amino-5-pyrimidylmethyl)-2- methyl pyridinium chloride hydrochloride. On recrystallization from a methanol-ethanol mixture, the quaternary had melting point 246°C (dec.).

Side Effects

Amprolium is considered one of the safest anticoccidial medications, and adverse reactions such as anorexia or diarrhoea may occur with high doses and prolonged use. Thiamine deficiency can cause central nervous system (CNS) symptoms, but can be reversed with the addition of thiamine to the diet. However, thiamine supplementation may affect the efficacy of the drug.
