Zinc is a cofactor for over 300 enzymes and is vital for maintaining cellular function, promoting wound healing, and modulating immune response. Its antioxidant properties also help to mitigate oxidative stress in the body.

Pharmacokinetics

Clear is absorbed in the gastrointestinal tract, with bioavailability varying based on the formulation. 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.

• Digestive issues

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 oxymel is not precisely defined but is believed to involve the combined effects of its constituents. Honey has natural antibacterial and anti-inflammatory properties, which may help soothe irritated mucous membranes and reduce coughing. Vinegar, particularly apple cider vinegar, is thought to have antimicrobial effects and may assist in breaking down mucus, facilitating easier breathing.

Pharmacodynamics

Oxymel is primarily used for its soothing effects on the throat and its potential to act as an expectorant. Honey can also stimulate the immune system and has been shown to possess antiviral properties. The presence of acetic acid in vinegar may help to alter the pH in the stomach, potentially enhancing digestive processes and nutrient absorption, indirectly supporting overall health during illness.

Pharmacokinetics

Due to its natural composition, the pharmacokinetics of oxymel are not extensively studied. However, the individual components, honey and vinegar, are rapidly absorbed in the gastrointestinal tract. Honey is metabolized primarily in the liver, while acetic acid is rapidly absorbed and metabolized through the Krebs cycle, providing energy and influencing metabolic pathways. The effects of oxymel are generally observed shortly after ingestion, depending on individual factors.

Pregnancy

Oxymel is traditionally used as a remedy and lacks extensive clinical studies to assess its safety during pregnancy. Caution is advised, and consultation with a healthcare provider is recommended.

Breast-feeding

Due to a lack of comprehensive studies, it is advisable to consult a healthcare professional before using oxymel while breastfeeding.

Storage

Store in a cool, dry place away from direct sunlight. Ensure the container is tightly closed to prevent contamination.

Formulations

• Syrup
• Liquid preparation

Indications

• Heart failure
• Edema
• Hypertension
• Congestive heart failure

Dosage

Children: Refer to the BNF for Children for specific dosage information regarding squill in paediatric patients.

Adults: Refer to the BNF for specific dosage information regarding squill in adults.

Mechanism of action

Squill contains cardiac glycosides, which inhibit the Na+/K+ ATPase enzyme. This inhibition leads to an increase in intracellular sodium levels, which causes an increase in intracellular calcium levels via the sodium-calcium exchanger. This results in enhanced myocardial contractility (positive inotropic effect) and a reduction in heart rate (negative chronotropic effect). Additionally, squill promotes diuresis by increasing renal blood flow and glomerular filtration rate.

Pharmacodynamics

The positive inotropic effect of squill enhances cardiac output and is useful in the management of certain heart conditions. The diuretic effect aids in fluid management, making it beneficial for patients with heart failure or edema. However, the therapeutic window is narrow, and toxicity can occur with overdose, leading to arrhythmias and gastrointestinal disturbances.

Pharmacokinetics

The pharmacokinetics of squill have not been extensively studied. However, it is generally understood that the active glycosides are absorbed in the gastrointestinal tract, with peak plasma concentrations occurring within a few hours after ingestion. The elimination half-life is variable and depends on the specific glycoside. The metabolites are primarily excreted via the kidneys.

Pregnancy

The safety of squill during pregnancy has not been established. Use only if clearly needed and prescribed by a healthcare provider.

Breast-feeding

It is not known whether squill is excreted in human milk. Caution should be exercised when administering to breastfeeding women.

Storage

Store in a cool, dry place, away from direct sunlight and moisture. Keep out of reach of children.

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.
