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.

Mechanism of action

Oxides do not have a single mechanism of action as they are a broad category of compounds. However, in general, metal oxides can exhibit catalytic properties, while non-metal oxides may participate in biochemical reactions by forming acids or bases upon dissolution in water.

Pharmacodynamics

The pharmacodynamics of oxides depend on the specific type of oxide and its interaction with biological systems. For instance, metal oxides may have antimicrobial properties, while certain non-metal oxides can influence metabolic pathways through their acid-base chemistry. The effects vary widely, necessitating specific studies for each oxide's role in therapeutic contexts.

Pharmacokinetics

The pharmacokinetics of oxides are also variable. Many metal oxides are poorly soluble and thus have limited absorption when ingested. Non-metal oxides, such as carbon dioxide, can be readily absorbed and utilized in metabolic processes. The distribution, metabolism, and excretion of oxides depend on their chemical form and the biological system in which they are involved.

Pregnancy

Not applicable as oxide is not a drug but a class of chemical compounds.

Breast-feeding

Not applicable as oxide is not a drug but a class of chemical compounds.

Storage

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

Indications

• Malaria caused by Plasmodium falciparum
• Malaria caused by Plasmodium vivax
• Severe malaria (as part of combination therapy)
• Fever of unknown origin in endemic areas

Dosage

Children: Refer to specific pediatric guidelines based on age, weight, and clinical status.

Adults: Refer to specific guidelines for dosing, considering individual patient factors such as severity of disease, renal function, and concurrent medications.

Mechanism of action

Quinine acts by interfering with the parasite's ability to metabolize and utilize erythrocyte hemoglobin. It is known to inhibit heme polymerization, which is required for the detoxification of free heme. This leads to the accumulation of toxic heme within the malaria parasite, ultimately resulting in its death. Additionally, quinine has effects on the cardiac muscle by blocking sodium channels and has some antipyretic effects through its action on the hypothalamus.

Pharmacodynamics

Quinine exhibits a dose-dependent reduction in parasitemia and has been shown to increase survival rates in severe malaria cases. It has a long half-life, which allows for once-daily dosing in some situations. Quinine's analgesic and antipyretic effects provide symptomatic relief in febrile conditions. Quinine can cause dose-dependent side effects including cinchonism, which is characterized by tinnitus, headache, and gastrointestinal disturbances.

Pharmacokinetics

Quinine is well absorbed from the gastrointestinal tract and reaches peak plasma concentrations within 1 to 3 hours post-administration. It is extensively metabolized in the liver, primarily by cytochrome P450 enzymes, with a half-life ranging from 10 to 12 hours. The drug is excreted mainly in the urine as metabolites, with a small percentage being eliminated unchanged. Renal impairment can increase the half-life and necessitate dosage adjustments.

Pregnancy

Insufficient data available to establish safety in pregnancy. Consult a healthcare provider for guidance.

Breast-feeding

Limited data on excretion in breast milk; caution is advised. Consult a healthcare provider.

Storage

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

Indications

• Acute diarrhea
• Chronic diarrhea
• Gastrointestinal upset
• Mild gastrointestinal inflammation

Dosage

Children: Refer to BNF for Children for specific dosing guidance.

Adults: Refer to BNF for specific dosing guidance.

Mechanism of action

Subgallate exerts its effects mainly through its astringent action, which leads to the precipitation of proteins in the gastrointestinal tract. This process results in the formation of a protective barrier that helps to reduce fluid secretion, enhances mucosal integrity, and decreases stool frequency. It also promotes the absorption of fluids and electrolytes, aiding in the management of diarrhea.

Pharmacodynamics

The pharmacodynamics of subgallate involve its ability to bind to proteins and mucins in the gastrointestinal lining, thereby providing a protective effect against irritants and inflammatory agents. Its astringent properties help reduce secretions and increase the absorption of fluids in the intestines. Subgallate may also have mild antibacterial effects, contributing to its efficacy in treating certain types of diarrhea.

Pharmacokinetics

Subgallate is not extensively absorbed systemically and primarily acts locally within the gastrointestinal tract. After administration, it exerts its therapeutic effects directly where it is required. The onset of action is relatively rapid, and the duration of effect can vary depending on the formulation and individual patient factors. Metabolism and excretion details for subgallate are limited, but it is generally eliminated from the gastrointestinal tract without significant systemic absorption.

Pregnancy

Subgallate may be used during pregnancy if the potential benefit justifies the potential risk to the fetus. Consult healthcare professionals for specific guidance.

Breast-feeding

It is unknown whether subgallate is excreted in human milk. Caution should be exercised when administering to breastfeeding women.

Storage

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