Methyl cellulose polymer consisting of numerous linked glucose molecules used as a stabiliser, thickener and emulsifier for foodstuffs and cosmetics. The Degree of Substitution (DS) of a given form of methyl cellulose is defined as the average number of substituted hydroxyl groups per glucose with a theoretical maximum of 3, however more typical values are 1.3 2.6. Methyl cellulose is a hydrophilic white powder in pure form and dissolves in cold (but not in hot) water, forming a clear viscous solution or gel. It is available under a variety of trade names as a treatment for constipation. Like cellulose, it is not digestible, not toxic, and not allergenic
It increases the bulk in your stool, an effect that helps to cause movement of the intestines. It also works by increasing the amount of water in the stool, making the stool softer and easier to pass.
Naphazoline is a rapid acting imidazoline sympathomimetic vasoconstrictor of ocular or nasal artierioles. It acts to decrease congestion and is found in many over the counter (OTC) eye drops and nasal preparations.
Naphazoline was first developed in 1942 as a nasal formulation for congestion.
Naphazoline is a sympathomimetic alpha adrenergic agonist that acts to vasoconstrict nasal or ocular arterioles, resulting in reduced congestion at the site of administration.

Uses
Methylcellulose is a compound used as a bulk forming laxative and is not an approved medication.
Solutions containing methyl cellulose are used as substitute for tears or saliva if the natural production of these fluids is disturbed. It is also used or constipation, diverticulosis, hemorrhoids and irritable bowel syndrome. Used in the manufacture of capsules in nutritional supplements. Its edible and nontoxic properties provide a vegetarian alternative to the use of gelatin.
Naphazoline is a sympathomimetic vasoconstrictor used for the symptomatic relief of redness and itching of the eye, and nasal congestion.
Naphazoline is indicated for use as OTC eyedrops for ocular vasoconstriction or as a nasal preparation for nasal congestion.
E Line is also used to associated treatment for these conditions: Constipation, Dry Eye Syndrome (DES), Eye disinfectionBacterial Conjunctivitis, Blepharoconjunctivitis, Conjunctivitis, Conjunctivitis allergic, Dacryocystitis, Dacryostenosis, Dermatitis, Eczematous of the Eyelid, Eye Pain, Eye redness, Iritis, Lacrimation, Nasal Allergies, Nasal Congestion, Noninfective conjunctivitis, Otitis Media (OM), Photophobia, Foreign body sensation in eye, Ocular bacterial infections, Ocular vasoconstriction
How E Line works
Methylcellulose absorbs water in the gastrointestinal lumen thereby increasing the bulk of the stool. This leads to distension and stimulation of peristalsis. The ability of methylcellulose to absorb water may contribute to its efficacy in the management of diarrhea by once again increasing the bulk and consistency of the stool.
Naphazoline is a vasoconstrictor that functions by stimulating alpha adrenergic receptors in arterioles leading to decreased congestion at the site of administration.
Naphazoline causes the release of norepinephrine in sympathetic nerves. Norepinephrine binds to alpha adrenergic receptors and causes vasoconstriction. Naphazoline is also a mild beta adrenergic receptor agonist, which can cause rebound vasodilation after the alpha adrenergic stimulation has ended. Naphazoline's release of norepinephrine also triggers a negative feedback loop which decreases production of norepinephrine, which can lead to rhinitis medicamentosa after long term use when naphazoline is stopped.
Toxicity
Organism: Mouse Test type: LD50 Route : Intraperitoneal Reported Dose: 275gm/kg ( 275000mg/kg) Toxic Effect: Details of toxic effects not reported other than lethal dose value
Organism: Mouse Test type: LDLo Route : Intravenous Reported Dose: 1gm/kg ( 1000mg/kg) Toxic Effect: Details of toxic effects not reported other than lethal dose value
In high doses or when ingested, naphazoline can lead to central nervous system depression (which can progress to coma and death), hypothermia, bradycardia, and death. This effect is especially pronounced in children under 6 years.
Long term use of naphazoline can lead to rhinitis medicamentosa once naphazoline is stopped. This condition is a result of norepinephrine release by naphazoline triggering a negative feedback loop.
Safety and effectiveness in children under 12 has not been established. Studies in elderly patients have yet to be performed. Risk in pregnancy, breast feeding, and on overall fertility have not been established, though pregnant and breast feeding patients should consider the risk and benefit before starting naphazoline treatment.
Volume of Distribution
accumulation in liver, spleen, lymph nodes, kidney, and vascular walls.
Distribution data for naphazoline are scarce but imidazoline compounds are distributed throughout the body, and can cross the blood-brain barrier.
Elimination Route
Cellulose derivatives considered in this report are virtually unabsorbed and little or no degradation of absorbed and little or no degradation of absorbable products occurs in the human digestive tract. In humans, virtually 100 percent of orally ingested methyl cellulose can be recovered in the feces withihn four days, indicating that absorption does not occur.
Absorption data for naphazoline are scarce but imidazoline compounds in general are weakly basic and lipophilic, with high bioavailability from the gastrointestinal tract.
Half Life
4.2 minutes
Half life has not been determined but effects last for 4 to 8 hours. Other imidazoline compounds have half lives varying from 2 to 12 hours.
Clearance
Clearance data for naphazoline is unavailable.
Elimination Route
When swallowed they are not absorbed to any appreciable degree and appear unchanged in feces.
Imidazoline compounds undergo some hepatic metabolism but a large fraction of the dose may be excreted unchanged in the urine. Urinary excretion is higher with more acidic urine.
