Ranydol Spas

Uses

Dimethicone is an ingredient used to treat dry and irritated eyes.

Dimethicone is a colorless liquid with both cosmetic and therapeutic uses. It is used in topical creams and ointments to help distribute the active ingredients. Dimethicone is used as an anti-foaming agent, a hair and skin conditioner, and in the treatment of head lice and, as an anti-bloating/anti-flatulence agent , .

How Ranydol Spas works

When applied topically, dimethicone forms a layer to delay the evaporation of water . In the treatment of head lice dimethicone 100, the respiratory systems of head lice are targeted. NYDA works by suffocating the lice, nymphs and the embryos. The physical properties of this drug, including the viscosity and spreading property of the solution allow it to easily flow into the respiratory system of all developmental stages of the insect, causing suffocation and death of the organisms. It diffuses through the stigmata (spiracles) of the lice, into the tracheae of the head lice as well as through the aeropyles of the egg operculum. The solution then displaces oxygen. The low viscosity, volatile dimethicone enables the NYDA head lice solution to penetrate into the breathing system. Its evaporation causes the thickening of the NYDA solution. The remaining high viscosity dimethicone ultimately encloses the respiratory system and thus leading to suffocation of all stages of head lice (adult lice, larvae and eggs). This mode of action prevents the development of lice resistance by preventing the formation of new progency .

Studies performed using house crickets and lice suggest a close correlation between the death of the lice and the influx of the solution into the insect head tracheae. These data strongly suggest that the total filling of the head tracheae immediately blocks the oxygen supply to the insect central nervous system. Death, following numerous stages of disability after the entrance of dimethicones into the abdominal tracheal system, demonstrates the sequence of oxygen deprivation. NYDA was applied directly to the head and mouth of the organism, and was found to have no effect when applied solely to the outside of the head/mouth .

Domperidone acts as a gastrointestinal emptying (delayed) adjunct and peristaltic stimulant. The gastroprokinetic properties of domperidone are related to its peripheral dopamine receptor blocking properties. Domperidone facilitates gastric emptying and decreases small bowel transit time by increasing esophageal and gastric peristalsis and by lowering esophageal sphincter pressure. Antiemetic: The antiemetic properties of domperidone are related to its dopamine receptor blocking activity at both the chemoreceptor trigger zone and at the gastric level. It has strong affinities for the D2 and D3 dopamine receptors, which are found in the chemoreceptor trigger zone, located just outside the blood brain barrier, which - among others - regulates nausea and vomiting

Dosage

Ranydol Spas dosage

Adults: 10 - 20 mg every 4 - 8 hours daily

Children: 0.2 - 0.4 mg/kg every 4 - 8 hours daily.

Domperidone tablet and suspension should be taken 15 - 30 minutes before a meal. For acute nausea and vomiting, maximum period of treatment is 12 weeks.

Side Effects

Domperidone may produce hyperprolactinemia which may cause galactorrhea & breast enlargement, soreness and reduced libido. It may rarely cause dry mouth, thirst, headache, nervousness, drowsiness, diarrhea, skin rash and itching.

Toxicity

The minimum lethal oral dose of dimethicone 200 (50 cs), dimethicone 550 (75 cs), dimethicone in rats .

A 76-week dietary toxicity study of a silicone antifoam compound (94% polydimethylsiloxane silicone oil and 6% silicone dioxide) was performed in mice. Three groups were given diet containing 0, 0.25%, or 2.5% of the test article. The dose levels in the treatment groups were estimated to be 580 and 5800 mg/kg/day. Mortality was increased in the 5800 mg/kg/day females. No target organs of toxicity were observed. The no-effect dose was 580 mg/kg/day. This study is of limited usefulness for assessing the toxicity of dimethicones, due to the small number of organs/tissues that were examined .

In one clinical study, 145 subjects were treated with either NYDA (dimethicone )or with a permethrin-based lice product. The number of subjects experiencing any adverse events was similar in both groups. In the NYDA group, 29 adverse events were reported in 25 subjects. All except two adverse events were categorized as being unrelated to the lice treatment (e.g., superficial wound after a fall, otitis externa following swimming in a pool). Two patients in the NYDA group experienced ocular irritation after treatment when the product entered the eyes. The irritation resolved spontaneously in both cases after rinsing the eyes with clean water .

Side effects include galactorrhea, gynecomastia, or menstrual irregularities.

Precaution

Domperidone should be used with absolute caution in case of children because there may be an increased risk of extra-pyramidal reactions in young children because of an incompletely developed blood brain barrier.

Interaction

Domperidone may reduce the hypoprolactinaemic effect of bromocriptine. Anti-muscarinics and opioid analgesics may antagonize the action of Domperidone on gastrointestinal function.

Volume of Distribution

Following injection of [14C]dimethicone fluid in the hind limb of rats, the radioactivity was distributed primarily in the gastrointestinal tract, and no evidence of metabolism was observed. When [14C]dimethicone was administered through i.p. injection in rats, the following distribution of radioactivity was observed at 25 days after dosing: 51% in adipose tissue, 27% in gastrointestinal tissues, and 15% in liver .

Elimination Route

This drug is not believed to be absorbed when used in quantities from 1-30% .

Half Life

7 hours

Pregnancy & Breastfeeding use

Use in pregnancy: The safety of this drug has not been established for pregnant women. So it is not recommended during pregnancy.

Use in lactation: Domperidone may precipitate galactorrhea and improve postnatal lactation, which is secreted in breast milk but in very small quantities insufficient to be considered harmful.

Contraindication

Domperidone is contraindicated to the patients who have hypersensitivity to this drug and in case of neonates.

Acute Overdose

Overdose has been reported primarily in infants and children. Symptoms of overdosage may include disorientation, somnolence and extrapyramidal reactions. There is no specific antidote to domperidone, but in the event of overdose, the administration of activated charcoal may be useful. Anticholinergics, antiparkinson drugs may be useful in controlling extrapyramidal reactions. The patient should be observed closely and supportive measures employed.

Storage Condition

Store in a cool dry place protected from light. Keep out of reach of children.
