Oxytocin is a nonapeptide (nine amino acids) hormone secreted by the posterior pituitary. Oxytocin produces action both peripherally and in the brain. Oxytocin is released by males and females during orgasm and is considered by many to be the hormone of desire, social recognition and bonding. 


Traditionally, Oxytocin has been administered by injection or nasal spray  because oral dose forms would be destroyed by the gastrointestinal tract. Belmar Pharmacy compounds new options for patients in both an Oral Tablet of Oxytocin in our BLA System and a Sublingual tablet which is dissolved under the tongue.

The oral tablet version from Belmar utilizes our proprietary 
BLA System which is designed to present Oxytocin to the lymphatic network for absorption. Click on BLA System for more information about our absorption mechanism. 

Tablets (both oral and sublingual) are more convenient than injections and nasal sprays. They are scored for dosing options, stable and travel well. 

Oxytocin has recently received significant interest in the Autism community. Researchers have found that autistic children have lower plasma levels of oxytocin than those of other children. Oxytocin plays a role in social behavior, including but not limited to: repetitive behaviors, the desire to form social bonds, social recognition, processing social cues, regulated feeding, excessive grooming, stress response and being aloof.

Oxytocin has also become the subject of studies in female sexual dysfunction specifically difficulty achieving orgasm. Oxytocin increases sexual receptivity and counteracts impotence. (Pedersen, C.A., 2002), (Arletti, 1997)
For more information on its use for this condition click the link below to see a presentation by Dr. Jorge Flechas:


Oxytocin has action on uterine contraction, milk letdown, orgasm, sexual arousal, bonding and maternal behavior. Side effects of Oxytocin from the literature on injection and nasal include: hemorrhage in the brain and uterus, increased blood pressure, heart rate and cardiac output, uterine contractions.
