Catoxymag-N suspension

Indications

• Indigestion
• Heartburn
• Gastroesophageal reflux disease (GERD)
• Peptic ulcer disease

Dosage

Children: Refer to the BNF for Children for appropriate dosing information in paediatric patients.

Adults: Refer to the BNF for specific dosing guidelines. Generally, aluminium hydroxide is taken as needed for symptom relief, often in the form of chewable tablets or liquid preparations.

Mechanism of action

Aluminium hydroxide works by reacting with hydrochloric acid in the stomach to form aluminum chloride and water, which reduces acidity and raises the pH level of gastric contents. This neutralization helps alleviate symptoms associated with acid-related disorders.

Pharmacodynamics

The pharmacodynamics of aluminium hydroxide involves its ability to neutralize gastric acid, leading to an increase in gastric pH. This results in a decrease in pepsin activity, which can alleviate symptoms of acid reflux and protect the gastric mucosa. It may also have a mild constipating effect due to its aluminum content.

Pharmacokinetics

Aluminium hydroxide is not significantly absorbed systemically; its primary action is localized to the gastrointestinal tract. When administered, it acts quickly to neutralize gastric acid, with effects typically observed within minutes. The elimination of aluminum from the body occurs primarily through the kidneys, although its low solubility limits systemic absorption.

Interactions

• aluminiumhydroxide+deferasirox: Severe (decreases exposure)
• aluminiumhydroxide+enteralfeeds: Unknown (increases risk of blocked enteral or nasogastric tubes)
• aluminiumhydroxide+roxadustat: Unknown (decreases exposure)

Indications

• Nutritional supplementation
• Herbal therapy for various conditions
• Preservation of medicinal properties of plants

Dosage

Children: Dosage for dried herbal preparations in children should be approached cautiously and is best determined by a healthcare professional. Refer to paediatric guidelines for specific dosing recommendations.

Adults: Dosage for dried herbal preparations varies widely depending on the specific herb and its intended use. Refer to specific guidelines or reputable sources for dosing information.

Mechanism of action

The mechanism of action for dried herbal preparations varies depending on the specific plant material involved. Generally, the active constituents in dried herbs can exert their effects through various pathways, such as modulating neurotransmitter systems, influencing metabolic pathways, and acting on specific receptors in the body. For instance, flavonoids, terpenes, and alkaloids found in certain dried herbs can exhibit anti-inflammatory, antioxidant, or antimicrobial properties.

Pharmacodynamics

The pharmacodynamics of dried drugs depend on their specific chemical constituents. These compounds can affect physiological functions, such as modulating inflammatory responses, enhancing immune function, or affecting neurotransmission. The effects can vary widely based on the type of herb, the method of drying, and the concentration of active ingredients.

Pharmacokinetics

The pharmacokinetics of dried herbal preparations can vary significantly based on the specific herb used. Generally, after ingestion, the active compounds are absorbed in the gastrointestinal tract, metabolized primarily by the liver, and then excreted through urine or feces. The bioavailability of these compounds can be influenced by factors such as the form of the preparation (e.g., powder, extract), the presence of other food substances, and individual patient characteristics.

Pregnancy

Safety during pregnancy has not been established. Consult a healthcare provider before use.

Breast-feeding

Consult a healthcare provider before use during breastfeeding.

Storage

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

Dosage

Children: Refer to specific guidelines for pediatric dosing; consult the BNF for Children for accurate dosage information.

Adults: Refer to specific guidelines for use; dosage may vary based on the context of use.

Mechanism of action

Hydroxide ions act primarily as bases, neutralizing acids to form water and salts. They participate in various biochemical pathways, including selenium metabolism and the degradation of reactive oxygen species. Hydroxide can influence enzyme activity and stability by altering the pH of the environment, thereby affecting metabolic reactions.

Pharmacodynamics

Hydroxide ions can impact biological processes by changing the local pH, which influences enzyme activity, ion transport, and the solubility of other compounds. Their ability to neutralize acids can help regulate physiological pH, contributing to homeostasis in living organisms.

Pharmacokinetics

As an inorganic ion, hydroxide does not undergo traditional pharmacokinetic processes like absorption, distribution, metabolism, or excretion. Instead, it is rapidly equilibrated in biological fluids and participates in acid-base reactions, having immediate effects on the local environment.

Pregnancy

There is limited information regarding the use of hydroxide during pregnancy. Consult a healthcare professional for advice.

Breast-feeding

Limited data is available on the excretion of hydroxide in breast milk. Consult a healthcare professional before use.

Storage

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

Indications

• Gastroesophageal reflux disease (GERD)
• Peptic ulcer disease
• Dyspepsia
• Heartburn
• Flatulence

Dosage

Children: Refer to specific medication guidelines for pediatric dosing recommendations.

Adults: Refer to specific medication guidelines for dosing recommendations.

Mechanism of action

The aluminum hydroxide and magnesium hydroxide components act as antacids by neutralizing gastric acid, which raises the pH of the stomach contents. Simethicone works by reducing surface tension of gas bubbles, facilitating their elimination. This combined action helps to relieve symptoms associated with hyperacidity and gas.

Pharmacodynamics

Triscilicate provides symptomatic relief from conditions caused by excess gastric acid. The antacids neutralize the acid, providing quick relief from peptic discomfort, while simethicone helps to reduce bloating and abdominal pain caused by gas. The onset of action is typically rapid, often within minutes.

Pharmacokinetics

Aluminum and magnesium salts are minimally absorbed from the gastrointestinal tract; their effects are primarily local. Aluminum can accumulate in renal impairment, while magnesium can have a laxative effect. The elimination half-lives vary, but generally, the compounds are excreted through feces and urine, with the majority of their action occurring in the gut.

Pregnancy

Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Consult healthcare professionals for guidance.

Breast-feeding

Use with caution. Consult healthcare professionals for advice regarding the use in breastfeeding mothers.

Storage

Store at room temperature, away from moisture and heat. Keep out of reach of children.
