Pantothenic acid is essential to normal epithelial function. The topical use of dexpanthenol, the stable alcoholic analog of pantothenic acid, is based on good skin penetration and high local concentrations of dexpanthenol when administered in an adequate vehicle, such as water-in-oil emulsions. Topical dexpanthenol acts like a moisturizer, improving stratum corneum hydration, reducing trans-epidermal water loss and maintaining skin softness and elasticity.Dexpanthenol is an alcohol derivative of pantothenic acid, a component of the B complex vitamins and an essential component of a normally functioning epithelium. Dexpanthenol is enzymatically cleaved to form pantothenic acid, which is an essential component of Coenzyme A, which acts as a cofactor in many enzymatic reactions that are important for protein metabolism in the epithelium.Dermatological effects of the topical use of dexpanthenol include increased fibroblast proliferation and accelerated re-epithelialization in wound healing. Furthermore, it acts as a topical protectant, moisturizer, and has demonstrated anti-inflammatory properties

Pantothenic acid is a precursor of coenzyme A, which serves as a cofactor for a variety of enzyme-catalyzed reactions involving transfer of acetyl groups. The final step in the synthesis of acetylcholine consists of the choline acetylase transfer of acetyl group from acetylcoenzyme A to choline. Acetylcholine is the neurohumoral transmitter in the parasympathetic system and as such maintains the normal functions of the intestine. Decrease in acetylcholine content would result in decreased peristalsis and in extreme cases adynamic ileus.

Xylometazoline is a sympathomimetic agent with marked alphaadrenergic activity, and is intended for use in the nose. It constricts the nasal blood vessels, thereby decongesting the mucosa of the nose and neighboring regions of the pharynx. This enables patients suffering from colds to breathe more easily through the nose. The effect of Xylometazoline begins within a few minutes and persists for several hours. Xylometazoline is generally well tolerated and does not impair the function of ciliated epithelium. Systemic absorption may occur following nasal application of Xylometazoline.

Xylometazoline is a sympathomimetic agent that causes vasoconstriction of the nasal mucosa. In one study comprising subjects with nasal congestion associated with the common cold, the median time of onset of subjective relief of nasal congestion was about 1.7 minutes and the time of subjective peak relief of nasal congestion was 30 minutes. Previous studies reported rebound swelling, rebound nasal congestion, rhinitis medicamentosa, and shorter duration of decongestant effect from the long-term use of xylometazoline in healthy volunteers, suggesting that the drug is most effective if used temporarily.

An early in vitro study demonstrated xylometazoline to exert anti-oxidant actions, where it inhibited microsomal lipid peroxidation and mediated hydroxyl radical scavenging activity. This suggests that xylometazoline has a beneficial effect against oxidants, which play a role in tissue damage in inflammation.

How Nasosyn works

Dexpanthenol is an alcohol derivative of pantothenic acid, a component of the B complex vitamins and an essential component of a normally functioning epithelium. Dexpanthenol is enzymatically cleaved to form pantothenic acid, which is an essential component of Coenzyme A, which acts as a cofactor in many enzymatic reactions that are important for protein metabolism in the epithelium.

Dermatological effects of the topical use of dexpanthenol include increased fibroblast proliferation and accelerated re-epithelialization in wound healing. Furthermore, it acts as a topical protectant, moisturizer, and has demonstrated anti-inflammatory properties .

Nasal congestion is caused by various etiologies, such as rhinosinusitis and allergic or non-allergic rhinitis, leading to congestion of the venous sinusoids lining the nasal mucosa. Activation of α-adrenergic receptors leads to vasoconstriction of the blood vessels of the nasal mucosa and resumption of nasal airflow. As the most abundantly expressed in the human nasal mucosa, α1A- and α2B-adrenoceptors may play the most important role in vasoconstriction of the human nasal mucosa. Xylometazoline is a more selective agonist at α2B-adrenoceptors, with affinity at α1A-, α2A-, α2C-, α1B-, and α1D-adrenoceptors. Xylometazoline decreases nasal resistance during inspiration and expiration and increases the volume of nasal airflow. Compared to oxymetazoline, another imidazoline nasal decongestant, xylometazoline had a slightly faster onset of action although they had a similar duration of action. In one study, subjects with nasal congestion reported relief of earache and sore throat in addition to nasal decongestion: it is speculated that oxymetazoline mediates this effect by causing vasoconstriction of the nasal mucosa that contains the venous sinuses and nasal decongestion allows breathing through the nose, providing relief from sore throat caused by mouth breathing that dries and irritates the throat.

Dosage

Nasosyn dosage

Check with the doctor or pharmacist if you are unsure how to use Dexpanthenol.

The usual dosage is generally:

  • Diaper rash: Apply a thin layer on the baby’s bottom at every diaper change.
  • Nipples: Apply a thin layer on the nipples after each nursing session. Wash the nipples thoroughly before the next nursing session.
  • Dry/cracked skin or light wounds and chafed skin: Apply to the dry areas and/or to the wound up to 3 times a day.
Do not exceed the recommended dose, Do not swallow. This medicine is intended for external use only.

Adults: 2 or 3 drops of Xylometazoline Adult formula (0.1%) two to three times daily. This adult formula should not be used for children under the age of 12 years.Children under 12 years: 1 or 2 drops of the Xylometazoline children's formula (0.05%) in each nostril once or twice daily. Not to be used in infants less than 3 months.

Side Effects

As with any medicine, use of Dexpanthenol may cause side effects in some users. Do not be alarmed by the list of side effects. You may not suffer from any of them. Discontinue use and refer to a doctor immediately in the event of: Allergic reaction and/or allergic skin reaction such as: atopic dermatitis, allergic dermatitis, pruritus, redness, rash, eczema, urticaria, local irritation or blistering. If a side effect occurs, worsens, or if you suffer from a side effect not mentioned in this leaflet, consult with the doctor.

The following side effects have occasionally been encountered: a burning sensation in the nose and throat, local irritation, nausea, headache, and dryness of the nasal mucosa. Systemic cardiovascular effects have occurred, and this should be kept in mind when giving Xylometazoline to people with cardiovascular disease.

Toxicity

Mouse LD50 : 9gm/kg (Intraperitoneal) Mouse: LD50 7gm/kg (Intravenous) Mouse: LD50 15gm/kg (Oral) Rabbit LD50 4gm/kg (Oral)

The oral LD50 is 230 mg/kg in rats and 75 mg/kg in mice. The subcutaneous LD50 is 90 mg/kg in rats and 53 mg/kg in mice. The intraperitoneal LD50 is 43 mg/kg in rats.

Xylometazoline poisoning is documented in three pediatric patients who were exposed to a drug concentration 40 times above the adequate dosage for children due to a compounding error: these patients experienced bradypnea and sinus bradycardia with supraventricular extrasystoles and were managed with fluid management.

Precaution

Each Xylometazoline pack should be used by one person only to prevent any cross-infection. Patients are advised not to take decongestants for more than seven consecutive days.

Interaction

No drug interactions have been reported.

Volume of Distribution

Dexpanthenol is readily converted to pantothenic acid which is widely distributed into body tissues, mainly as coenzyme A. Highest concentrations are found in the liver, adrenal glands, heart, and kidneys.
