Mechanism of action

Ammonium ions participate in various metabolic pathways, including the biosynthesis of amino acids and nucleotides. It serves as a nitrogen source for organisms, facilitating the synthesis of essential biomolecules. The presence of ammonium can influence pH levels and osmotic balance within cells, thereby affecting cellular functions and enzyme activities.

Pharmacodynamics

Ammonium affects cellular metabolism by acting as a nitrogen donor in the synthesis of organic compounds. Its role in the nitrogen cycle and as a substrate in biochemical pathways allows for the maintenance of cellular functions, including energy production and cellular growth. Alterations in ammonium levels can influence various physiological processes, including neurotransmitter synthesis and energy metabolism.

Pharmacokinetics

Ammonium is readily absorbed and distributed in biological systems. It can be produced endogenously through amino acid metabolism or obtained from dietary sources. The excretion of ammonium primarily occurs through the kidneys, where it is converted to urea for elimination. Ammonium levels are regulated by various mechanisms, including the action of renal tubular cells that either secrete or reabsorb ammonium based on the body's needs.

Indications

• Cough associated with respiratory tract infections
• Acid-base disorders
• Edema management

Dosage

Children: Refer to the BNF for Children for appropriate paediatric dosing guidelines based on age and condition.

Adults: Refer to the BNF for specific adult dosing guidelines as they depend on the indication and clinical context.

Mechanism of action

Ammonium chloride increases acidity by raising hydrogen ion concentrations. It dissociates into ammonium and chloride ions; the ammonium is converted to urea in the liver, releasing hydrogen ions that lower pH. The chloride ions displace bicarbonate in extracellular fluid, leading to acidosis and increased renal excretion of electrolytes and water, resulting in fluid mobilization.

Pharmacodynamics

Ammonium chloride acts as a systemic acidifier, facilitating the excretion of chloride and sodium, while also increasing the acidity of body fluids. The conversion of ammonium to urea in the liver with the release of hydrogen ions contributes to a decrease in blood pH, affecting acid-base balance in the body.

Pharmacokinetics

Ammonium chloride is absorbed from the gastrointestinal tract and metabolized in the liver, where it is converted to urea. The dissociated ions impact renal function, leading to increased excretion of sodium, potassium, and water. The elimination half-life and specific metabolism details are not explicitly defined.

Adverse effects

• Nausea
• Vomiting
• Abdominal pain
• Diarrhea
• Dizziness
• Headache

Interactions

• Antacids may reduce the effectiveness of ammonium chloride

Mechanism of action

Cocobenzyldimethyl exerts its antibacterial effects by interacting with the phospholipid bilayer of the microbial cell membrane. This interaction increases membrane permeability, causing leakage of cellular contents and ultimately resulting in cell death. Additionally, it may alter the surface tension of biological fluids, enhancing its effectiveness as a disinfectant.

Pharmacodynamics

Cocobenzyldimethyl demonstrates broad-spectrum antimicrobial activity against a variety of bacteria, fungi, and viruses. Its cationic nature allows it to bind to negatively charged cell surfaces, facilitating penetration and disruption of the microbial cell membrane. Its activity is concentration-dependent, with higher concentrations leading to more rapid bactericidal effects.

Pharmacokinetics

The pharmacokinetics of cocobenzyldimethyl are not well-characterized due to its primary use in topical applications. Systemic absorption is minimal; thus, systemic side effects are rare. Metabolism and excretion pathways are not extensively studied, but it is expected to be eliminated primarily via local degradation at the site of application.

Indications

• High-level disinfection of heat-sensitive medical instruments
• Sterilization of surgical and medical equipment
• Preservation of biological specimens

Dosage

Children: Refer to specific product guidelines for use in paediatric settings, as dosing and exposure times may vary based on the type of equipment being disinfected and institutional protocols.

Adults: Refer to specific product guidelines for appropriate concentrations and exposure times for disinfection and sterilization. The concentration of glutaraldehyde used typically ranges from 2% to 3% for disinfection purposes, with a contact time of 20 to 30 minutes.

Mechanism of action

Glutaraldehyde exerts its antimicrobial effects by forming cross-links with proteins and nucleic acids, disrupting cellular structure and function. This leads to the inactivation of microorganisms, including bacteria, fungi, and viruses. Its efficacy is attributed to its ability to penetrate microbial cell walls and react with essential cellular components.

Pharmacodynamics

The pharmacodynamic profile of glutaraldehyde indicates that it has potent bactericidal, virucidal, and sporicidal properties. Its activity is concentration-dependent, meaning higher concentrations lead to more rapid microbial kill rates. Glutaraldehyde is effective against a wide range of pathogens, making it suitable for high-level disinfection and sterilization protocols.

Pharmacokinetics

Glutaraldehyde is not intended for systemic use, and therefore, traditional pharmacokinetic parameters such as absorption, distribution, metabolism, and excretion are not typically applicable. When used as a disinfectant, it acts locally on the surfaces of instruments or equipment, with minimal systemic absorption.

Adverse effects

• Irritation of skin, eyes, and respiratory tract
• Allergic reactions
• Nausea
• Headaches

Precautions

• Use with caution in patients with a history of respiratory disorders
• Avoid contact with skin and mucous membranes

Pregnancy

There is limited data on the use of glutaraldehyde during pregnancy, hence it should be used only if the potential benefit justifies the potential risk to the fetus.

Breast-feeding

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

Storage

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

Formulations

• Solution for disinfection
• Sterilizing agent

Mechanism of action

Ammonium chloride increases acidity by increasing the amount of hydrogen ion concentrations. Ammonium chloride can be used as an expectorant due to its irritative action on the bronchial mucosa. This effect causes the production of respiratory tract fluid which in order facilitates the effective cough. The acid-forming properties of ammonium chloride result from dissociation of the salt to an ammonium cation and a chloride anion. In patients with normal hepatic function, the ammonium cation is converted to urea by the liver and a hydrogen cation is released which reacts with a bicarbonate ion to form water and carbon dioxide. The chloride anion combines with fixed bases in the extracellular fluid, thereby reducing the alkaline reserve of the body. The net result is the displacement of bicarbonate ions by chloride anions. The displacement of bicarbonate by chloride alters the bicarbonate:carbonic acid ratio if the body and acidosis results. The increased chloride concentration in the extracellular fluid produces an increased load to the renal tubules and appreciable amounts of chloride anions escape reabsorption. These anions are excreted along with cations and water. Sodium is the principal cation excreted; however, potassium excretion may also be increased to some degree. By increasing the excretion of both extracellular electrolytes and water, ammonium chloride causes a net loss of extracellular fluid and promotes the mobilization of edema fluid.

Pharmacodynamics

Systemic acidifier. In liver ammonium chloride is converted into urea with the liberation of hydrogen ions ( which lowers the pH) and chloride.
