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

• Cardiac arrest in the context of metabolic acidosis

Dosage

Children: Refer to the BNF for Children for specific pediatric dosages, as they depend on the clinical condition

Adults: Refer to local guidelines and BNF for specific dosing recommendations as they may vary based on clinical condition and severity. General adult dosing for bicarbonate may range from 1 to 2 mEq/kg IV initially, followed by maintenance doses as needed.

Mechanism of action

Bicarbonate acts as a buffer that neutralizes excess acids in the body. It dissociates in solution to produce bicarbonate ions (HCO3-) which can react with hydrogen ions (H+) to form carbonic acid (H2CO3), subsequently leading to the production of carbon dioxide (CO2) and water (H2O). This process helps to raise the pH of the blood and other fluids, counteracting acidosis. Bicarbonate is involved in several metabolic pathways, including the urea cycle and various biosynthetic pathways.

Pharmacodynamics

Bicarbonate's primary pharmacodynamic effect is its ability to buffer hydrogen ions, thus increasing blood pH. This is essential in conditions such as metabolic acidosis, where the body accumulates excess acid. By raising blood pH, bicarbonate can help alleviate symptoms associated with acidemia, such as fatigue, confusion, and shortness of breath. Its effects can also influence the renal and respiratory systems to regulate acid-base homeostasis.

Pharmacokinetics

Bicarbonate is rapidly absorbed from the gastrointestinal tract. It is distributed throughout the body fluids, and its effects can be seen within minutes of administration. The kidneys play a significant role in bicarbonate homeostasis by reabsorbing bicarbonate from urine and excreting hydrogen ions. The elimination half-life can vary, depending on the patient's metabolic state and renal function.

Pregnancy

Use with caution. Consult with a healthcare provider before use.

Breast-feeding

Use with caution. Consult with a healthcare provider before use.

Storage

Store in a cool, dry place away from light.

Indications

• Acute poisoning
• Overdose of certain toxins
• As an emetic in specific clinical scenarios

Dosage

Children: For children, the dosage is typically 10 to 15 mL of syrup of ipecac for children aged 1 year and older. Again, it is crucial to seek guidance from a poison control center or healthcare provider.

Adults: For adults, the typical dose for inducing emesis is 15 to 30 mL of syrup of ipecac, taken orally. However, due to the risks associated with its use, consultation with a poison control center or healthcare provider is recommended for specific situations.

Mechanism of action

Ipecacuanha contains alkaloids such as emetine and cephaeline, which stimulate the chemoreceptor trigger zone in the medulla oblongata, leading to the induction of vomiting. These compounds also increase gastric motility and secretions, further contributing to its emetic effect.

Pharmacodynamics

The emetic action of ipecacuanha is dose-dependent, with lower doses potentially causing nausea without vomiting, while higher doses can lead to significant emesis. Its effects are mediated through the central nervous system and gastrointestinal tract.

Pharmacokinetics

Ipecacuanha is absorbed through the gastrointestinal tract, with peak plasma concentrations occurring within 1-3 hours after administration. The elimination half-life and specific metabolic pathways of the active components are not well characterized, but they are believed to be metabolized in the liver and excreted primarily in urine.

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.

Contra-indications

• Hypersensitivity to any component of the tincture

Formulations

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

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.
