Oxytocin
Oxytocin (Oxt) is a peptide hormone and neuropeptide. Oxytocin is normally produced by the paraventricular nucleus of the hypothalamus and released by the posterior pituitary. It plays a role in social bonding, sexual reproduction, childbirth, and the period after childbirth. Oxytocin is released into the bloodstream as a hormone in response to stretching of the cervix and uterus during labor and with stimulation of the nipples from breastfeeding. This helps with birth, bonding with the baby, and milk production. Oxytocin was discovered by Henry Dale in 1906. Its molecular structure was determined in 1952. Oxytocin is also used as a medication to facilitate childbirth.
Oxanamide
Oxanamide (Quiactin) is an anxiolytic and muscle relaxant which can produce sedative and hypnotic effects in sufficiently high doses. An uncontrolled trial on patients treated in a clinical gynecology practice published in 1959 found that oxanamide was efficacious in the treatment of anxiety resulting from premenstrual syndrome, menopause, and various other causes, with minimal sedation or other side effects.
