Metabolite Identification
Common NameRitodrine
DescriptionRitodrine, also known as du-21220Ritodrine or prepar, belongs to the class of organic compounds known as phenethylamines. Phenethylamines are compounds containing a phenethylamine moiety, which consists of a phenyl group substituted at the second position by an ethan-1-amine. Ritodrine is a drug which is used for the treatment and prophylaxis of premature labour. This drug has been removed from the US market, according to FDA Orange Book. The passage of β agonists through the placenta does occur and may be responsible for fetal tachycardia, as well as hypoglycemia or hyperglycemia at birth. Ritodrine is a very strong basic compound (based on its pKa). Ritodrine (trade name Yutopar) is a tocolytic drug used to stop premature labor. Also, the 4-hydroxy group on the benzene ring is important for activity as it is needed to form hydrogen bonds. However, the 4-hydroxy group makes it susceptible to metabolism by catechol-O-methyl transferase (COMT). Since it is β2-selective it is used for premature labor. Most side effects of β2 agonists result from their concurrent β1 activity, and include increase in heart rate, rise in systolic pressure, decrease in diastolic pressure, chest pain secondary to myocardial infarction, and arrhythmia. Patients with type 2 diabetes, high blood pressure or migraines should bring this to their doctor's attention before receiving care. Since ritodrine has a bulky N-substituent, it has high β2 selectivity.
