Dextran is a polysaccharide that differs from others in that its glucose units are joined together 1:6 glucoside links. The main chain of glucose has short branches at frequent intervals which are probably joined by 1:3 and 1:4 glucoside links. The chains can be composed of about 200,000 glucose units. Many bacteria, like Leuconostoc, can synthesize dextran from sucrose, and this activity is used commercially to obtain dextran.

Dextran 40 is a sterile, nonpyrogenic preparation of low molecular weight dextran (average mol. wt. 40,000) in 5% Dextrose Injection or 0.9% Sodium Chloride Injection. It is administered by intravenous infusion.

Dextran 75 is a complex branched glucan with an average molecular weight 75000 Daltons. It is produced from certain bacteria that with α-1,6 glycosidic linkages between glucose molecules and α-1,3 linkages between branches. When labelled with technetium Tc99m, dextran 75 is intravenously administered as an imaging agent to detect and diagnose conditions in the vascular compartment such as pericardial effusion or ventricular aneurysm.

Glycerin is a hyperosmotic laxative, given rectally, which usually produces a bowel movement within 15 minutes to 1 hour. Hyperosmotic laxatives encourage bowel movements by drawing water into the bowel from surrounding tissues. This produces a softer stool mass and increased bowel action. These products are used for fast, predictable relief of occasional constipation.

Glycerin is commonly classified as an osmotic laxative but may act additionally or alternatively through its local irritant effects; it may also have lubricating and fecal softening actions. Glycerin suppositories usually work within 15 to 30 minutes.

Uses

Dextran is a low molecular weight dextran used as an adjunctive treatment of shock or impending shock due to hemorrhage, burns, surgery or other trauma, as well as the prophylaxis of venous thrombosis and pulmonary embolism during high-risk medical procedures.

Dextran is used as the restoration of blood mass during surgical interventions if there is hypovolemia due to trauma or dehydration. It is as well used after the presence of hemorrhage in cases of blood loss to a level inferior to 15% of the blood mass, if compatibility test cannot be completed or when blood lots need to be tested for pathogen detection. Dextran is also used for the prevention of profound postoperative venous thrombosis.

Dextran as well presents ophthalmic applications as solutions or ointments for the temporary relief of xerophthalmia or minor ocular irritations.

For the relief of occasional constipation

How Aqona Teas Eye Drops works

In preclinical studies, the mechanism of action is thought to be related to the blockage of the uptake of tissue plasminogen activator by mannose-binding receptors. This process has a direct effect by enhancing endogenous fibrinolysis.

When administered rectally, glycerin exerts a hygroscopic and/or local irritant action, drawing water from the tissues into the feces and reflexively stimulating evacuation. Glycerin decreases intraocular pressure by creating an osmotic gradient between the blood and intraocular fluid, causing fluid to move out of the aqueous and vitreous humors into the bloodstream.

Dosage

Aqona Teas Eye Drops dosage

Children under 2 years: Consult a physician.

Children (2 to 6 years): only 1 Glycerin 1.15 suppository per 24 hours or as directed by a physician.

Adults and Children (From 6 years): only 1 Glycerin 2.30 suppository per 24 hours or as directed by a physician

Insert suppository well up into rectum. Suppository need to melt completely to produce laxative action.

Side Effects

Glycerin when used rectally may cause rectal discomfort or a burning sensation

Toxicity

Some reports have shown adverse effects when used in therapeutical doses and some teratogenic effects have been demonstrated when used in large doses. The current LD50 reported in rats is 10700 mg/kg.

Glycerol has very low toxicity when ingested ; Rat LD50 (oral)-12600mg/kg Mice LD50 (oral )-4090mg/kg Human TDLo (oral) - 1428mg/kg

Volume of Distribution

The reported volume of distribution of dextran suggested a distribution throughout the blood volume. This volume of distribution is reported to be of around 120 ml. The organ that presented a higher accumulation of dextran was the liver.

Glycerin is distributed throughout the blood. Although glycerin generally does not appear in ocular fluids, it may enter the orbital sac when the eye is inflamed, with a consequent decrease in osmotic effect.

Elimination Route

Dextran presents a very low oral bioavailability that is reduced as the chain gets longer. Thus, the bioavailability of dextran is inversely proportional to the length of the carbohydrate chain.

Well absorbed orally, poorly absorbed rectally. Studies in humans and animals indicate glycerol is rapidly absorbed in the intestine and the stomach

Half Life

The elimination half-life will depend on the length of the carbohydrate chain. The higher the molecular weight of the dextran the longer it will be the elimination half-life. The half-life will go from 1.9 hours from dextran 1 to 42 hours in the case of dextran 60.

30 - 45 minutes

Elimination Route

The elimination of dextran will depend on the length of the carbohydrate chain, the administration route, and the molecular weight. For dextran 1, it is reported to be mainly secreted unchanged in the urine in a ratio of 80% of the administered dose when administered parentally. It is registered that the weight threshold for unrestricted glomerular filtration is about 15 kDa and if the dextran overpasses 50 kDa it will not be renally eliminated in any significant amount.

Approx 7-14% of dose is excreted unchanged in the urine within 2.5 hr.
