• Gastroesophageal reflux disease (GERD)
• Heartburn
• Diarrhea
• Mucosal irritations

Dosage

Children: Refer to the BNF for Children for appropriate dosing guidelines.

Adults: Refer to the BNF for specific dosing recommendations based on the condition being treated.

Mechanism of action

Aluminum acts as an astringent, causing local shrinkage or constriction of body tissues through osmotic flow of fluids away from the area of application. This mechanism assists in reducing mucous secretions and managing conditions such as peptic ulcers and diarrhea. Additionally, it can help in drying and hardening of tissues when applied topically.

Pharmacodynamics

Aluminum-based antacids work by neutralizing gastric acid, leading to an increase in gastric pH. This action helps to alleviate symptoms associated with excess gastric acid, such as heartburn and discomfort. The astringent properties of aluminum also contribute to its therapeutic effects in managing mucosal irritations and secretions.

Pharmacokinetics

Aluminum is absorbed minimally when taken orally, with a bioavailability of about 0.1 to 0.5%. The majority of aluminum is excreted renally, and its half-life can be prolonged in individuals with renal impairment. Long-term use may lead to accumulation and potential toxicity, particularly impacting bone and neurological health.

Mechanism of action

Bicarbonate functions primarily as a buffering agent. In the body, it helps to neutralize excess acids by reacting with hydrogen ions (H+) to form carbonic acid (H2CO3), which can then be converted to carbon dioxide (CO2) and water (H2O) for excretion. This reaction helps to maintain blood pH within a narrow range, which is crucial for normal cellular function.

Pharmacodynamics

Bicarbonate administration increases blood bicarbonate levels, leading to a rise in blood pH (alkalosis). This effect can reverse conditions of metabolic acidosis where there is an excess of hydrogen ions. It can also enhance the excretion of certain drugs that are weak acids by alkalinizing urine, thereby altering the renal clearance of those substances.

Pharmacokinetics

Sodium bicarbonate is rapidly absorbed from the gastrointestinal tract after oral administration. Its effects are seen within 30 minutes to 2 hours, depending on the formulation. The bicarbonate ion is distributed throughout the extracellular fluid. It is metabolized and acts as a buffer to maintain acid-base homeostasis. The duration of action is variable and influenced by factors such as the underlying condition being treated and concurrent medications.

Dosage

Children: Refer to the BNF for Children for specific dosing recommendations.

Adults: Refer to the BNF for specific dosing recommendations.

Mechanism of action

Bismuth exerts its therapeutic effects primarily by coating the mucosal lining of the gastrointestinal tract, which protects it from irritants and helps to reduce inflammation. It also has antimicrobial properties that may help to eradicate Helicobacter pylori, a bacterium associated with peptic ulcers. The exact mechanisms at the molecular level include the formation of a protective barrier and the inhibition of bacterial growth.

Pharmacodynamics

Bismuth compounds demonstrate a protective effect on the gastric mucosa, promoting healing in ulcerative and inflammatory conditions. The antimicrobial properties of bismuth also contribute to its efficacy in treating gastrointestinal infections, particularly those caused by H. pylori. Additionally, bismuth exhibits mild antisecretory effects, which can help to alleviate symptoms of diarrhea.

Pharmacokinetics

Bismuth is poorly absorbed from the gastrointestinal tract, which allows it to exert its effects locally while minimizing systemic exposure. Following oral administration, it travels through the gastrointestinal system, where it is primarily retained in the gut. Any absorbed bismuth is excreted through the kidneys, and its half-life is relatively short due to minimal systemic absorption.

Contra-indications

Dosage

Children: Specific dosing information is not available for carbonicum. Its levels in the body are generally maintained through normal physiological processes.

Adults: Specific dosing information is not available for carbonicum. Its levels in the body are generally maintained through normal physiological processes.

Mechanism of action

Carbon dioxide acts as a signaling molecule in various physiological pathways. It is involved in the regulation of blood pH, respiratory drive, and vasodilation. Elevated levels of carbon dioxide in the blood lead to respiratory acidosis, stimulating the respiratory center in the brain to increase ventilation and expel excess CO2, thus regulating acid-base balance.

Pharmacodynamics

Carbon dioxide is a naturally occurring compound that influences various systems in the body. It helps in the transport of oxygen from the lungs to the tissues and assists in the regulation of blood pH. The presence of CO2 in the blood affects the affinity of hemoglobin for oxygen, a phenomenon known as the Bohr effect, which enhances oxygen delivery to tissues during states of increased metabolism.

Pharmacokinetics

Carbon dioxide is produced endogenously during cellular respiration and is eliminated primarily via the lungs. It diffuses readily across biological membranes due to its gaseous state. The body maintains homeostasis of carbon dioxide levels tightly through respiratory and metabolic mechanisms. The half-life of carbon dioxide in the blood is very short, as it is continuously being produced and exhaled.

Pregnancy

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

Breast-feeding

It is unknown whether carbonicum is excreted in human milk. Caution is advised when administering to breastfeeding women.

Storage

Mechanism of action

Papain, the primary enzyme in carica, acts as a protease, facilitating the hydrolysis of peptide bonds in proteins. This enzymatic activity aids in digestion by breaking down proteins into more easily absorbed amino acids and peptides. Additionally, the antioxidants in carica may help reduce oxidative stress, thereby exhibiting anti-inflammatory effects.

Pharmacodynamics

The pharmacodynamic effects of carica largely stem from its enzymatic activity and antioxidant properties. Papain enhances protein digestion, improving nutrient absorption. The antioxidants present in carica, such as vitamin C, help neutralize free radicals, potentially reducing inflammation and promoting overall health. The anti-inflammatory effects may also be beneficial in managing conditions associated with inflammation.

Pharmacokinetics

The pharmacokinetics of carica are not well defined in clinical literature, as it is primarily consumed as a food source rather than a pharmaceutical product. However, the absorption of nutrients and enzymes from carica can vary based on the individual's digestive health. The bioavailability of papain may be influenced by factors such as gastric pH, presence of other food substances, and individual metabolic rates.

Pregnancy

There is insufficient reliable information regarding the safety of carica during pregnancy, so it is advisable to avoid use unless directed by a healthcare professional.

Mechanism of action

Aluminum Acetate is an astringent. An astrignent is a chemical that tends to shrink or constrict body tissues, usually locally after topical medicinal application. The shrinkage or constriction is through osmotic flow of water (or other fluids) away from the area where the astringent was applied. Astringent medicines cause shrinkage of mucous membranes or exposed tissues and are often used internally to check discharge of blood serum or mucous secretions. This can happen with a sore throat, hemorrhages, diarrhea, or with peptic ulcers. Externally applied astringents, which cause mild coagulation of skin proteins, dry, harden, and protect the skin. Acne sufferers are often advised to use astringents if they have oily skin. Astringents also help heal stretch marks and other scars. Mild astringent solutions are used in the relief of such minor skin irritations as those resulting from superficial cuts, allergies, insect bites, or fungal infections such as athlete's foot. Excessive dietary aluminum has been proposed to be a factor contributing to several neurological disorders in humans. Six 8-week-old female Swiss Webster mice were fed for 10 wk purified diets containing 100 (control), 500 or 1000 ug aluminum/g diet. Brain and liver lipid peroxidation was determined by evaluating the production of 2-thiobarbituric acid reactive substances in brain and liver homogenates in the presence or absence of 50 uM ferrous iron. 2-Thiobarbituric acid reactive substances production in the absence of iron in brain homogenates from mice fed the 1000 ug/g diet was higher (30%) than that in the 100 ug/g control group (3.1 vs 2.4 nmol 2-thiobarbituric acid reactive substances/mg protein). The addition of ferrous iron increased 2-thiobarbituric acid reactive substances production in brain homogenates from all 3 dietary groups. The iron induced 2-thiobarbituric acid reactive substances production was 26% higher in the 1000 ug/g brain homogenates than in the 100 ug/g group (4.9 vs 3.9 nmol 2-thiobarbituric acid reactive substances/mg protein). Brain 2-thiobarbituric acid reactive substances production in the presence and absence of iron was similar between the 100 and 500 ug/g aluminum groups. 2-Thiobarbituric acid reactive substances production in liver homogenates measured either with or without iron was similar for the 3 groups. These results show that, in mice, dietary aluminum intoxication leads to increased brain 2-thiobarbituric acid reactive substance production, suggesting that enhanced lipid peroxidation may be one possible mechanism underlying the neurological damage associated with increased tissue aluminum. Evidence is presented indicating that dementias are associated with a relative insufficiency of magnesium in the brain. Such insufficiency may be attributable to low intake or retention of magnesium; high intake of a neurotoxic metal, such as aluminum, which inhibits activity of magnesium requiring enzymes; or impaired transport of magnesium and/or enhanced transport of the neurotoxic metal into brain tissue. It is proposed that Alzheimer's disease involves a defective transport process, characterized by both an abnormally high incorporation of aluminum and an abnormally low incorporation that an altered serum protein contributes to the progression of Alzheimer's disease by having a greater affinity for aluminum than for magnesium, in contrast to the normal protein, which binds magnesium better than aluminum. The altered protein crosses the blood-brain barrier more efficiently than the normal protein and competes with the normal protein in binding to brain neurons. Binding of the altered protein to the target neurons would both facilitate aluminum uptake and impede magnesium uptake. Evidence suggests that albumin is the serum protein that is altered. Aluminum is established as a neurotoxin, although the basis for its toxicity is unknown. It recently has been shown to alter the function of the blood-brain barrier, which regulates ex
