What is Orexin?

Orexin, also known as hypocretin, is a neuropeptide that regulates arousal, alertness, and appetite. The most common form is narcolepsy, type 1, in which the patient experiences a short loss of muscle tone. This is caused by a lack of orexin in the brain due to the destruction of the cells that produce it.


Orexin Uses

This product is a combination of B vitamins used to treat or prevent vitamin deficiency due to poor diet, certain illnesses, alcoholism, or pregnancy. Vitamins are important building blocks for your body and help keep you in good health. Thiamine, riboflavin, niacin/niacinamide, vitamin B6, vitamin B12, folic acid and pantothenic acid are all B vitamins. Ingredients such as vitamin C, vitamin E, biotin, and zinc are also present in certain brands of B vitamins. Consult your doctor or pharmacist if you have any questions about the ingredients in your brand.

How to use Orexin

Take this medicine orally, usually once a day or as directed. Follow all directions on the package of products. If you are taking a brand containing vitamin C, take this medicine by mouth with a full glass of water (8 ounces/240 milliliters) unless otherwise directed by your doctor. If you are taking chewable tablets, chew the tablets thoroughly before swallowing.

If you take extended-release capsules, swallow them whole. Do not crush or chew capsules or tablets with extended-release. Doing so can release all drugs at once, increasing the risk of side effects. Also, do not split the extended-release tablets unless they have a score line and your doctor or pharmacist will tell you to do so. Swallow the whole tablet or split tablet without crushing or chewing it.

If you are taking a liquid product, use a medicament measuring device to measure the dose carefully. Don't use a household spoon. Some liquid products must be shaken before each dose. Some products having vitamin B12 must be kept on the tongue and held there before swallowing.

Take this medicine on a regular basis to make the most benefit from it. To help you remember, take it every day at the same time.

Frequently Asked Questions

What is the function of orexin?

Orexins are lateral hypothalamic neuropeptides that play a very important role in the regulation of alertness. In order to promote feeding behavior, orexin neurons are stimulated by food-related signals and/or low energy balance through neuronal connections to the limbic system and energy balance factors.

How does orexin affect sleep?

It is assumed that the primary role of orexins is to control sleep and excitement, and the neurons that release orexins are most active during the day. To keep us awake, these neuropeptides stimulate other neurons to release alert neurotransmitters such as dopamine, serotonin, and norepinephrine.

What does orexin due to hunger?

Crucial evidence indicates that orexin-A increases the intake of food by delaying the onset of a behaviorally normal satiety sequence. A selective orexin-1 receptor antagonist, on the other hand, suppresses food intake and advances the onset of normal satiety sequence.

How does orexin regulate the sleep/wake cycle?

They were initially recognized as feed behavior regulators, but are primarily seen as key sleep/wakefulness cycle modulators. Orexins activate orexin neurons, monoaminergic and cholinergic neurons in the hypothalamus/brainstem regions to maintain a long, consolidated waking period.

What causes a lack of orexin?

Many cases of narcolepsy are thought to be caused by a lack of a brain chemical called hypocretin (also known as orexin) that regulates sleep. The deficiency is assessed as the result of the immune system incorrectly attacking parts of the brain that produce hypocretin.

Is orexin a hormone or neurotransmitter?

Orexins (also known as hypocretins) are neurotransmitters produced in small neuronal populations within the lateral (LH) and peripheral (PFA) areas of the hypothalamus. The name orexin was derived from the Greek root word for appetite, orexis.

How is orexin produced?

Orexin-A and-B (also known as hypocretin-1 and-2) are neuropeptides produced in the lateral hypothalamus that promote many aspects of arousal via the OX1 and OX2 receptors. In fact, they are necessary for normal alertness, as the loss of orexin-producing neurons causes narcolepsy in humans and rodents.
