Indications

• Cerebral edema
• Elevated intracranial pressure
• Acute kidney injury
• Oliguria
• Glaucoma
• Renal function diagnostic aid

Dosage

Adults: For cerebral edema, administer 0

Mechanism of action

Mannitol elevates blood plasma osmolality, resulting in enhanced flow of water from tissues, including the brain and cerebrospinal fluid, into interstitial fluid and plasma. This action reduces cerebral edema and intracranial pressure. As a diuretic, it increases the osmolality of glomerular filtrate, leading to increased urinary excretion of water and preventing sodium and chloride reabsorption in the renal tubules. Mannitol also facilitates the urinary excretion of toxic substances and can help in assessing renal function by measuring glomerular filtration rate (GFR).

Pharmacodynamics

Mannitol is classified as an osmotic diuretic. It is chemically similar to other sugar alcohols but has a unique ability to promote diuresis by remaining unabsorbed in the renal tubules. Its use is indicated for conditions associated with increased body fluids, such as cerebral edema and glaucoma. Mannitol may be combined with other diuretics to enhance diuretic efficacy. Inhaled formulations are used in cystic fibrosis, though they may cause bronchospasm and hemoptysis.

Pharmacokinetics

Mannitol is freely filtered by the glomeruli with less than 10% tubular reabsorption, which allows for its urinary excretion rate to serve as a measurement of GFR. It does not undergo significant metabolism and is eliminated primarily through the kidneys. The onset of action occurs within 30 to 60 minutes after intravenous administration, with effects lasting for several hours. Administration may require monitoring of renal function and fluid balance.

Mechanism of action

While there is no well-controlled data to formally substantiate the method of action, ongoing studies suggest that allantoin may induce a histological wound healing profile in animal models, leading to improved reestablishment of normal skin. This includes increased vasodilation, inflammatory cell presence, angiogenesis, fibroblast proliferation, and collagen deposition in treated wounds compared to untreated ones.

Pharmacodynamics

There is limited controlled data regarding the pharmacodynamic properties of allantoin. However, studies indicate that allantoin may possess moisturizing and keratolytic effects, increasing the extracellular matrix's water content and enhancing the desquamation of dead skin cells. These activities can promote cell proliferation and facilitate wound healing.

Pharmacokinetics

Specific pharmacokinetic data for allantoin in humans is limited. However, it is known to be applied topically, which suggests local absorption at the site of application. Systemic absorption is considered minimal due to its low molecular weight and hydrophilicity.

Mechanism of action

Maltodextrin is readily metabolized by the body to glucose. Upon ingestion, it is broken down by enzymes in the digestive tract into simpler sugars, which are then absorbed into the bloodstream. This rapid conversion supports immediate energy needs, particularly during physical activity.

Pharmacodynamics

Maltodextrin primarily serves as a source of energy, particularly for athletes and individuals requiring rapid glucose replenishment. Its high glycemic index means it can quickly raise blood sugar levels, providing immediate energy. Additionally, maltodextrin can help improve hydration status and nutrient absorption when included in rehydration solutions.

Pharmacokinetics

Maltodextrin is absorbed quickly in the gastrointestinal tract, leading to a rapid increase in plasma glucose concentrations. The peak plasma glucose levels typically occur within 30 minutes to 1 hour after consumption. The metabolic pathway involves conversion to glucose, which can then be utilized by various tissues for energy or stored as glycogen in the liver and muscles.

Dosage

Children: Refer to specific peptide formulations for dosing recommendations, as they vary widely based on the intended use and formulation.

Adults: Refer to specific peptide formulations for dosing recommendations, as they vary widely based on the intended use and formulation.

Mechanism of action

Peptides exert their effects by binding to specific receptors on target cells, initiating a cascade of intracellular signaling pathways. This can lead to various physiological responses such as modulation of enzyme activity, gene expression, and cellular metabolism. The specific mechanism varies according to the peptide's structure and the biological system it affects.

Pharmacodynamics

The pharmacodynamic profile of peptides is closely related to their structure and the receptors they target. Many peptides function as hormones, neurotransmitters, or growth factors, leading to dose-dependent effects. The potency and efficacy of a peptide are influenced by factors such as receptor affinity, downstream signaling pathways, and the presence of receptor antagonists.

Pharmacokinetics

Peptides are typically administered via injection as they can be degraded by gastrointestinal enzymes when taken orally. Their absorption, distribution, metabolism, and elimination vary based on the peptide's size, structure, and formulation. Generally, peptides have short half-lives due to rapid enzymatic degradation. Modifications to peptide structure can enhance stability and bioavailability.

Indications

• Caloric reduction in food and beverages
• Management of diabetes
• Weight management

Dosage

Children: Refer to the BNF for Children for specific guidelines on the use of sucralose in pediatric populations.

Adults: Sucralose is typically used in food and beverage products as a sweetener. There are no specific dosage recommendations for adults, as it is used according to taste preference and product formulation.

Mechanism of action

Sucralose acts as a positive allosteric modulator of the human sweet taste receptor. It interacts with the T1R taste receptor family, particularly enhancing the sweetness perception by binding to the hinge region of the receptor. This interaction induces a conformational change that stabilizes the active state of the receptor, increasing its responsiveness to sweet stimuli. This mechanism allows sucralose to mimic the taste of sugar without the associated caloric intake.

Pharmacodynamics

As a non-nutritive sweetener, sucralose does not undergo metabolic processing in the body, which means it does not contribute to energy intake. It provides intense sweetness at low concentrations, stimulating the sweetness receptors in the taste buds. The pharmacodynamic profile indicates minimal physiological effects beyond taste perception, making it suitable for dietary use without impacting blood glucose levels.

Pharmacokinetics

Sucralose is poorly absorbed in the gastrointestinal tract, with an estimated absorption rate of less than 15%. The majority of ingested sucralose is excreted unchanged in the urine. The elimination half-life is not well defined due to its minimal absorption, but it is generally considered to have a rapid clearance from the body. The pharmacokinetic properties support its use as a safe alternative to sugar for those managing caloric intake.

Pregnancy

Sucralose is generally considered safe during pregnancy, but it is recommended to consult a healthcare provider.

Breast-feeding

Sucralose is also considered safe during breastfeeding, although it is advisable to seek medical advice.

Storage

Store in a cool, dry place away from direct sunlight.

Formulations

• Granulated sucralose
• Liquid sucralose
• Tablets

Mechanism of action

Mannitol is an osmotic diuretic that is metabolically inert in humans and occurs naturally, as a sugar or sugar alcohol, in fruits and vegetables. Mannitol elevates blood plasma osmolality, resulting in enhanced flow of water from tissues, including the brain and cerebrospinal fluid, into interstitial fluid and plasma. As a result, cerebral edema, elevated intracranial pressure, and cerebrospinal fluid volume and pressure may be reduced. As a diurectic mannitol induces diuresis because it is not reabsorbed in the renal tubule, thereby increasing the osmolality of the glomerular filtrate, facilitating excretion of water, and inhibiting the renal tubular reabsorption of sodium, chloride, and other solutes. Mannitol promotes the urinary excretion of toxic materials and protects against nephrotoxicity by preventing the concentration of toxic substances in the tubular fluid. As an Antiglaucoma agent mannitol levates blood plasma osmolarity, resulting in enhanced flow of water from the eye into plasma and a consequent reduction in intraocular pressure. As a renal function diagnostic aid mannitol is freely filtered by the glomeruli with less than 10% tubular reabsorption. Therefore, its urinary excretion rate may serve as a measurement of glomerular filtration rate (GFR). The exact mechanism of action of inhaled mannitol in the symptomatic maintenance treatment of cystic fibrosis remains unclear. It is hypothesized that mannitol produces an osmotic gradient across the airway epithelium that draws fluid into the extracellular space and alters the properties of the airway surface mucus layer, allowing easier mucociliary clearance. MANNITOL IS.../USED/ IN PROPHYLAXIS OF ACUTE RENAL FAILURE. IT IS USED FOR THIS PURPOSE IN CONDITIONS AS DIVERSE AS CARDIOVASCULAR OPERATIONS, SEVERE TRAUMATIC INJURY, OPERATIONS IN THE PRESENCE OF SEVERE JAUNDICE, AND MGMNT OF HEMOLYTIC TRANSFUSION REACTIONS. IN EACH OF THESE CONDITIONS, A PRECIPITOUS FALL IN THE FLOW OF URINE MAY BE ANTICIPATED EITHER AS THE RESULT OF AN ACUTELY REDUCED FILTRATION RATE OR FROM ACUTE CHANGES IN TUBULAR PERMEABILITY. THE LATTER MAY BE CONSEQUENCE OF THE PRESENCE OF NOXIOUS AGENT WITHIN THE TUBULAR FLUID IN EXCESSIVELY HIGH CONCN, IN SOME INSTANCES SUFFICIENT TO RESULT IN ACTUAL PRECIPITATION. IN THESE SITUATIONS, MANNITOL EXERTS OSMOTIC EFFECT WITHIN THE TUBULAR FLUID, INHIBITS WATER REABSORPTION, & MAINTAINS THE RATE OF URINE FLOW. ...CONCN OF TOXIC AGENT WITHIN TUBULAR FLUID DOES NOT REACH EXCESSIVELY HIGH LEVELS THAT OTHERWISE WOULD HAVE BEEN ACHIEVED BY MORE COMPLETE REABSORPTION OF WATER. ...EVEN THOUGH /GLOMERULAR/ FILTRATION RATE IS REDUCED, MANNITOL IS STILL FILTERED @ GLOMERULUS. THE TUBULAR IMPERMEABILITY TO MANNITOL IS NOT ALTERED BY ACUTE RENAL ISCHEMIA OF SHORT DURATION. HENCE, THE MANNITOL THAT IS FILTERED IS ALSO EXCRETED IN THE VOIDED URINE. UNREABSORBED SOLUTE LIMITS BACK DIFFUSION OF WATER. ...URINE VOL CAN BE MAINTAINED EVEN IN PRESENCE OF DECR GLOMERULAR FILTRATION.

Pharmacodynamics

Chemically, mannitol is an alcohol and a sugar, or a polyol; it is similar to xylitol or sorbitol. However, mannitol has a tendency to lose a hydrogen ion in aqueous solutions, which causes the solution to become acidic. For this reason, it is not uncommon to add a substance to adjust its pH, such as sodium bicarbonate. Mannitol is commonly used to increase urine production (diuretic). It is also used to treat or prevent medical conditions that are caused by an increase in body fluids/water (e.g., cerebral edema, glaucoma, kidney failure). Mannitol is frequently given along with other diuretics (e.g., furosemide, chlorothiazide) and/or IV fluid replacement. Inhaled mannitol has the possibility to cause bronchospasm and hemoptysis; the occurrence of either should lead to discontinuation of inhaled mannitol.

Mechanism of action

There is no well controlled data that can formally substantiate the method of action. However, ongoing studies suggest that there may exist a histological wound healing profile induced by allantoin in rats that leads to the amelioration and fastening of the reestablishment of normal skin. This facilitation of wound healing is supported by observations that wounds inflicted to rat subjects to which topical allantoin preparations were applied histologically demonstrated increased vasodilation, presence of inflammatory exudates, number of inflammatory cells, angiogenesis, fibroblast proliferation, and increased collagen deposition when compared to rat subjects with wounds that did not receive any allantoin administration.

Pharmacodynamics

There is no well controlled and appropriate data that can formally substantiate the pharmacodynamic properties of allantoin. Nevertheless, ongoing studies suggest that allantoin possesses moisturizing and keratolytic effects, as well as abilities to increase the water content of the extracellular matrix and enhance the desquamation of upper layers of dead skin cells, all of which are activities that can promote cell proliferation and facilitate wound healing.
