The distribution of zinc in the body is primarily in muscle and bone, with renal excretion being the main route of elimination. The half-life of zinc can vary based on dietary intake and individual metabolism.

Indications

• Constipation
• Decreased intraocular pressure

Dosage

Children: For children, refer to the BNF for Children for appropriate glycerin dosing guidelines.

Adults: For constipation, glycerin can be administered rectally as a suppository. Follow specific product guidelines for dosage.

Mechanism of action

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

Pharmacodynamics

Glycerine is commonly classified as an osmotic laxative but may also exert local irritant effects, lubricating, and fecal softening actions. Its onset of action typically occurs within 15 to 30 minutes when used as a suppository.

Pharmacokinetics

Glycerine is readily absorbed and metabolized in the body. It undergoes glycerol metabolism pathways, contributing to various biochemical processes including phospholipid biosynthesis. The pharmacokinetic profile of glycerine indicates a rapid onset of action due to its osmotic properties.

Dosage

Children: For children over 1 year of age, a common dosage is 1 to 2 teaspoons of honey for cough relief. Honey should not be given to children under 1 year due to the risk of botulism.

Adults: For cough relief, a common recommendation is to take 1 to 2 tablespoons of honey, as needed. Honey can be taken directly or mixed with warm water or herbal teas.

Mechanism of action

Honey exhibits various mechanisms of action, including its antibacterial and anti-inflammatory properties. The high sugar concentration creates a hypertonic environment that inhibits the growth of bacteria. Additionally, honey contains hydrogen peroxide, methylglyoxal, and flavonoids that contribute to its antimicrobial effects. The antioxidant properties of honey help in mitigating oxidative stress and promoting wound healing.

Pharmacodynamics

The pharmacodynamics of honey involve its ability to promote healing and provide symptomatic relief from coughs and sore throats. Honey's viscosity and stickiness can coat the throat, providing a soothing effect and reducing irritation. Its natural sugars also serve as an energy source, while its antioxidants may help in reducing inflammation and promoting overall health.

Pharmacokinetics

Honey is primarily absorbed in the gastrointestinal tract. The sugars in honey are rapidly metabolized, providing quick energy. The absorption rate can vary based on the composition of the honey and individual digestive factors. Honey's components, including vitamins and minerals, may also have varying rates of absorption depending on the specific nutrient and the individual's metabolism.

Mechanism of action

The mechanism of action of tinctures depends on the specific herbs or plants used in their preparation. Generally, the active compounds extracted from the plant material interact with various biological pathways, including receptor modulation, enzyme inhibition, and antioxidant activity. For example, flavonoids and alkaloids found in many tinctures may exhibit anti-inflammatory, analgesic, or antimicrobial effects through their interaction with cellular signaling pathways.

Pharmacodynamics

The pharmacodynamics of tinctures is influenced by the specific constituents of the herbal material. These constituents may exert effects such as enhancing or inhibiting neurotransmitter activity, modulating inflammatory responses, or influencing metabolic pathways. The effects can vary widely among different tinctures based on the plant used, the extraction method, and the concentration of the active ingredients.

Pharmacokinetics

The pharmacokinetics of tinctures involves absorption, distribution, metabolism, and excretion of the active compounds. After administration, the alcohol or vinegar solvent aids in the rapid absorption of these compounds through the mucosal membranes or gastrointestinal tract. Once absorbed, the compounds are distributed throughout the body and may undergo metabolic transformations primarily in the liver. The elimination half-life varies based on the specific herb and its active constituents, with some compounds being excreted unchanged while others are metabolized into active or inactive metabolites.

Formulations

• Tinctures of various herbs and compounds, including but not limited to: echinacea, valerian, and calendula

Mechanism of action

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. Glycerin (glycerol) and sorbitol are hyperosmotic laxatives. When administered rectally, glycerin and sorbitol exert a hygroscopic and/or local irritant action, drawing water from the tissues into the feces and reflexly stimulating evacuation. The extent to which the simple physical distention of the rectum and the hygroscopic and/or local irritant actions are responsible for the laxative effects of some of these drugs is not known. Only extremely high oral doses of sorbitol (25 g daily) or glycerin exert laxative action. /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. The physicochemical effects of a series of alkanols, alkanediols and glycerol on erythrocyte shape and hemolysis at 4 and 20 degrees C were examined. We calculated the dielectric constant of the incubation medium, Ds, and the dielectric constant of the erythrocyte membrane Dm in the presence of organic solutes. The ratio Ds/Dm = -38.48 at 20 degrees C defines the normal biconcave shape in a medium without hemolytic agents. A decrease in Ds/Dm favors externalization or internalization with consequent hemolysis. Alkanols and alkanediols convert biconcave erythrocytes into echinocytes, which is accompanied by an increase in the projected surface area. Glycerol converts biconcave erythrocytes into stomatocytes, which was accompanied by a marginal decrease in the projected surface area. Progressive externalization in alkanols and alkanediols or internalization in glycerol resulted in a decrease in the projected surface area and the formation of smooth spheres. The degree of shape change induced was related to the degree of hemolysis and the ratio Ds/Dm. A decrease in temperature reduced both the degree of shape change and hemolysis. .../Thus/ physicochemical toxicity may be a result of a temperature dependent hydrophobic interaction between the organic solutes and the membrane and is best interpreted by the ability of the solutes to change Ds and Dm.

Pharmacodynamics

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.
