* Subject must be in good physical and mental health as judged by the Investigator based on evaluation of medical and gynecological history, physical examination, clinical laboratory, ECG, and vital signs data
* Subject is willing and able to comply with all conditions and requirements of the study

Exclusion Criteria:

* Lactation and/or pregnancy in the previous 6 months before screening, whichever is applicable
* Intention to become pregnant during the study or within 1 months after the follow up visit
* History of, or existing thromboembolic, cardiovascular or cerebrovascular disorder
* Treatment for any major psychiatric disorder in the previous 12 months or use of antidepressant medication before screening
* Any clinically significant abnormality following review of medical history, laboratory results and physical examination at screening as judged by the Investigator
* Conditions or disorders that might affect the absorption, distribution, metabolism or excretion of the study drugs
* Contraindications for the use of oxytocin
* Hypersensitivity to the active substances or to any of the excipients of the investigational product or reference therapy
* Present use or use within 30 days before the start of the study medication of one or more of the following medications: antihypertensive drugs, anti-coagulant therapy, medication that could affect myometrial contractility, sex steroids, prostaglandins and its analogues, inhalation anesthetics, vasoconstrictors/sympathomimetics and caudal anesthetics, vasopressin-like drugs
* Use of any prescribed or over-the-counter medication within 14 days before Day 1
* Administration of any other investigational drug within 3 months before Day 1 or participation in 3 or more clinical trials in the 10 months before Day 1
* Loss of more than 500 milliliters (mL) blood during the 3 months before Day 1, or intention to donate blood in the 3 months after completing the study
* Subjects with a positive test result for hepatitis B, hepatitis C, or human immunodeficiency virus (HIV) at screening
* Subjects with a history of alcohol or drug abuse or with a positive result at screening, for tests of alcohol intake or drugs of abuse
