详细说明

DrugBank - DB00867

• Drug Groups: approved
• Description: Adrenergic beta-agonist used to control premature labor. [PubChem]
• Indication: For the treatment and prophylaxis of premature labour
• Pharmacology: Beta-2 adrenergic receptors are located at sympathetic neuroeffector junctions of many organs, including uterus. Ritodrine is beta-2 adrenergic agonist. It stimulates beta-2 adrenergic receptor, increases cAMP level and decreases intracellular calcium concentration. The decrease of calcium concentration leads to a relaxation of uterine smooth muscle and, therefore, a decrease in premature uterine contractions.
• Toxicity: LD₅₀=64mg/kg (mice, IV); LD₅₀=540 mg/kg (mice, oral); LD₅₀=85 mg/kg (rat, IV)
• Affected Organisms: Humans and other mammals
• Biotransformation: Hepatic, by both the mother and fetus
• Half Life: 1.7-2.6 hours
