Oxitocina 5mg – Beligas(internacional)

Substância ativa ocitocina
Packs 1 frasco x 5 mg

A ocitocina é um hormônio secretado pelo lobo posterior da glândula pituitária, uma estrutura do tamanho de uma ervilha localizada na base do cérebro.

It’s sometimes known as the “cuddle hormone” or the “love hormone,” because it is released when people snuggle up or bond socially. Even playing with your dog can cause an oxytocin surge, according to a 2009 study published in the journal Hormones and Behavior. But these monikers may be misleading.

A ocitocina também pode intensificar memórias de vínculos que deram errado, como nos casos em que os homens têm relacionamentos ruins com suas mães. Ela também pode fazer com que as pessoas aceitem menos pessoas que veem como estranhas. Em outras palavras, se a ocitocina faz você se sentir afetuoso ou desconfiado dos outros depende do ambiente.

Ocitocina em mulheres

Oxytocin is a particularly important hormone for women. “Oxytocin is a peptide produced in the brain that was first recognized for its role in the birth process, and also in nursing,” said Larry Young, a behavioral neuroscientist at Emory University in Atlanta, Georgia.

The hormone causes uterine contractions during labor and helps shrink the uterus after delivery. When an infant suckles at his or her mother’s breast, the stimulation causes a release of oxytocin, which, in turn, orders the body to “let down” milk for the baby to drink.

Oxytocin also promotes mother-child bonding. Studies show that “female rats find pups to be aversive if [the females are] virgins,” Young told Live Science. “But once they give birth, the brain is transformed, so they find the pups irresistible,” he said. And similar findings are seen in humans.

A 2007 study published in the journal Psychological Science found that the higher a mom’s oxytocin levels in the first trimester of pregnancy, the more likely she was to engage in bonding behaviors such as singing to or bathing her baby. [11 Interesting Effects of Oxytocin]

Although maternal bonding may not always be hardwired — after all, human females can adopt babies and take care of them — oxytocin released during pregnancy “does seem to have a role in motivation and feelings of connectedness to a baby,” Young said. Studies also show that interacting with a baby causes the infant’s own oxytocin levels to increase, he added.

In men, as in women, oxytocin facilitates bonding. Dads who got a boost of oxytocin via a nasal spray played more closely with their 5-month-old babies than dads who didn’t get the hormone zap, a 2012 study found. (There is another hormone, called vasopressin, which plays a stronger role in men.)

This anti-social effect of a social hormone brings some nuance to the story of oxytocin. In one study, researchers found that Dutch students given a snort of the hormone became more positive about fictional Dutch characters, but were more negative about characters with Arab or German names. The finding suggests that oxytocin’s social bonding effects are targeted at whomever a person perceives as part of their in-group, the researchers reported in January 2011 in the journal PNAS.

Em outro estudo, publicado na PNAS em 2010, homens receberam uma dose de ocitocina e foram solicitados a escrever sobre suas mães. Aqueles com relacionamentos seguros descreveram suas mães como mais atenciosas após a dose do hormônio. Aqueles com relacionamentos problemáticos, na verdade, viam suas mães como menos atenciosas. O hormônio pode ajudar na formação de memórias sociais, de acordo com os pesquisadores do estudo, então uma cheirada fortalece associações anteriores, sejam elas boas ou ruins.

“My view of what oxytocin is doing in the brain is making social information more salient,” Young said. “It connects brain areas involved in processing social information — whether it’s sights, faces, sounds or smells — and helps link those areas to the brain’s reward system.”

Sprays de ocitocina e efeitos colaterais

Oxytocin nose sprays also have been considered for use in treating autism. The neurological disorder is marked by struggles with social functioning, so a small 2013 study published in the journal PNAS gave a dose to children and teens with autism and asked the participants to identify emotions based on pictures of people’s eyes.

The participants weren’t any better at identifying the emotions after the oxytocin burst, but the regions of their brains associated with social interaction became more active. The increased processing could mean that a burst of oxytocin might help cement behavioral therapy for kids with the disorder.

“When you think about using oxytocin to treat diseases like autism, you want to make sure you do it in a context where the social information is positive,” Young said.

O uso de sprays de ocitocina fora de um contexto médico é muito mais obscuro, no entanto. Os sprays vendidos online sem receita prometem alívio do estresse e facilidade social, mas não são regulamentados pela Food and Drug Administration (FDA). Isso significa que nada se sabe sobre sua eficácia, efeitos colaterais ou mesmo se eles contêm ocitocina.

Não há estudos de longo prazo sobre os efeitos colaterais dos sprays legítimos de ocitocina usados em pesquisas hormonais; a maioria dos estudos dá às pessoas apenas uma dose do hormônio. A ocitocina, uma versão sintética da ocitocina administrada intravenosamente para estimular o parto, tem efeitos colaterais que incluem náusea, vômito e dor de estômago.
