Flibanserin / Oxytocin Description1-9
Flibanserin has been used to treat hypoactive sexual desire disorder in premenopausal women. The goal of the medication is to increase sexual desire and the number of satisfying sexual events. Flibanserin, which has generally been administered at bedtime, has a half life of 11 hours. After oral administration, flibanserin reaches its peak concentration within 45 minutes, is approximately 33% orally bioavailable, and reaches steady state within 3 days.
Oxytocin is produced in the hypothalamus and stored in the posterior portion of the pituitary gland. Oxytocin is made synthetically and has activity identical to natural oxytocin. Oxytocin stimulates contraction of smooth muscle in the uterus during labor and stimulates the alveolar ducts to eject milk after it has been produced in the breast. Thus, because of the actions of oxytocin on the uterus, it has been used to induce labor, aid in the delivery of the placenta, and control postpartum bleeding. Oxytocin has also been associated with social bonding, mood regulation and sexual functioning.
Flibanserin1,2
An imbalance in the neurotransmitters dopamine (DA), norepinephrine (NA) and serotonin (5-HT) may affect the ability for women to have positive sexual desire (libido) and have satisfying sexual events. In the prefrontal cortex, serotonin may be at increased amounts while norepinephrine and dopamine may be at decreased levels. Flibanserin has activity on serotonin receptors (5-HT1A and 5-HT2A). This activity leads to elevated NE and DA levels and reduced serotonin levels within the prefrontal cortex intracellularly. The drug may also have activity on 5-HT2B, 5-HT2C, and DA D4 receptors. The drug has not been found to be addictive or lead to misuse.
Oxytocin3-9
Oxytocin causes G-protein coupled receptors to increase intracellular calcium which leads to uterine contraction. The stimulation of uterine contractions causes more oxytocin to be released. As more oxytocin is released it positively influences even more release of oxytocin. This release of oxytocin is called positive feedback which is much different than how many hormones work in the endocrine system. Oxytocin administered exogenously causes the same response as endogenously produced oxytocin. Not only does oxytocin stimulate uterine contractions, but it also causes contractions of myoepithelial cells in the alveolar ducts found in female breast tissue. These contractions force milk from these ducts into even larger sinuses, which subsequently enables milk expulsion. When a baby attempts to latch onto the mother’s breast it causes oxytocin secretion into the blood in the same manner as vaginal delivery; instead of uterine contractions, milk is ejected from the breast. Like the actions of oxytocin in the uterus to stimulate contractions during delivery, milk-ejection from breast tissue occurs due to positive feedback. In the brain, it is proposed that oxytocin stimulates social and sexual function by its activity in many areas of the brain including its activity on and with neurotransmitters including dopamine. Both oxytocin and dopamine have been found to increase in the brain during sexual activity.
