Sample Use Guides

Adults and Adolescents 12 Years of Age and Older: 1 tablet or 5 mL (1 teaspoonful) of the oral solution every 4 to 6 hours as needed; do not exceed 6 tablets or 30 mL (6 teaspoonfuls) in 24 hours. Children 6 to 11 Years of Age: 1/2 tablet or 2.5 mL (1/2 teaspoonful) of the oral solution every 4 to 6 hours as needed; do not exceed 3 tablets or 15 mL (3 teaspoonfuls) in 24 hours.
Route of Administration: Oral
Isolated caprine urinary bladder detrusor muscle strips were incubated with homatropine at 5 uM after being contracted with 100 mum acetylcholine. The drug inhibited the ACh-induced contraction of the caprine detrusor and that this inhibition was reversed by raising the concentration of ACh.
