• Intestinal amoebiasis
• Urogenital trichomoniasis
• Giardiasis

Dosage

Children: For children aged 1 month to 11 years, the dosage is 50–75 mg/kg once, with a maximum of 2 g per dose. For children aged 12 to 17 years, the dosage is 2 g for a single dose, which may be repeated once if necessary.

Adults: The usual adult dosage is 2 g taken orally as a single dose for urogenital trichomoniasis or giardiasis, and 1.5 g to 2 g once daily for 3 to 6 days for intestinal amoebiasis.

Mechanism of action

Tinidazole acts as a prodrug and antiprotozoal agent. Its nitro group is reduced in Trichomonas by a ferredoxin-mediated electron transport system, generating free nitro radicals that covalently bind to DNA, causing DNA damage and cell death. The exact mechanism of action against Giardia and Entamoeba species is not fully understood but is believed to be similar to that of Trichomonas.

Pharmacodynamics

Tinidazole demonstrates in vitro and clinical activity against Trichomonas vaginalis, Giardia duodenalis (also known as G. lamblia), and Entamoeba histolytica. It does not exhibit significant activity against most strains of vaginal lactobacilli, which are beneficial bacteria in the vaginal flora.

Pharmacokinetics

Tinidazole is well absorbed following oral administration, with peak plasma concentrations occurring within 0.5 to 3 hours. It is extensively distributed throughout body tissues and fluids. The drug undergoes hepatic metabolism and is eliminated primarily through the urine, with a half-life of approximately 12 to 14 hours. Clinical and laboratory monitoring is advised if treatment extends beyond 10 days.

Dosage

Children: For children aged 1 month to 5 years, the recommended dosage is 2.5 to 5 mL twice daily. Dosage may vary based on individual response and should be guided by a healthcare professional.

Adults: For adults, the typical dosage is 1 to 2 tablespoons (around 15 to 30 mL) mixed with at least 240 mL of water, taken up to three times daily. It is important to ensure adequate fluid intake to avoid gastrointestinal obstruction.

Mechanism of action

Methylcellulose acts as a bulk-forming laxative by absorbing water in the gastrointestinal tract. This increases the stool's bulk and promotes bowel motility through mechanical stimulation of the intestinal walls, which enhances peristalsis. It does not undergo significant metabolism and directly influences the physical properties of the stool.

Pharmacodynamics

The pharmacodynamic profile of methylcellulose indicates that it increases stool bulk and moisture content, facilitating easier passage of stool. The osmotic effect helps to soften the stool, while the bulk created stimulates intestinal contractions, reducing the time stool remains in the colon and alleviating constipation.

Pharmacokinetics

Methylcellulose is not absorbed systemically as it is a non-digestible fiber. Its effects are localized to the gastrointestinal tract. After oral administration, it acts primarily in the intestines, where it retains water to form a gel-like mass. The onset of action may vary, with effects usually observed within 24 to 72 hours.

Adverse effects

• abdominal discomfort
• bloating
• diarrhea
• nausea

Precautions

• Ensure adequate fluid intake to prevent intestinal blockage.
• Use cautiously in patients with pre-existing gastrointestinal disorders.

Pregnancy

Methylcellulose is generally considered safe during pregnancy. However, it is advisable to consult with a healthcare professional before use.

Indications

• Hypovolemic shock
• Severe burns
• Postoperative fluid replacement
• Sepsis
• Trauma management

Dosage

Children: Refer to established guidelines for specific dosing, as it varies based on the type of colloidal solution used and the clinical condition being treated.

Adults: Refer to established guidelines for specific dosing, as it varies based on the type of colloidal solution used and the clinical condition being treated.

Mechanism of action

Colloidal solutions work by maintaining oncotic pressure in the blood, thus helping to retain fluid within the vascular system. This is primarily due to the large molecular weight of the colloidal particles, which cannot easily pass through capillary walls. The presence of colloids in the blood helps to draw water into the circulation, increasing blood volume and improving tissue perfusion.

Pharmacodynamics

The pharmacodynamics of colloidal solutions are centered on their ability to exert osmotic pressure, which helps maintain blood volume and pressure. This effect is particularly important in conditions such as hypovolemia and shock, where fluid replacement is necessary to restore hemodynamic stability. The efficacy of colloidal solutions can vary depending on the type of colloid used, as well as the underlying clinical condition being treated.

Pharmacokinetics

Colloidal solutions are typically administered intravenously and their pharmacokinetics can vary based on the specific formulation. Generally, colloids are distributed throughout the vascular compartment and have a longer duration of action compared to crystalloids, as they remain in circulation longer. The elimination of colloids is primarily through the reticuloendothelial system, where they are metabolized or eliminated by the liver and spleen. Factors such as particle size and composition can influence their distribution and clearance.

Adverse effects

• Allergic reactions
• Injection site reactions
• Nausea
• Vomiting
• Headache
• Fever

Precautions

Mechanism of action

Croscarmellose sodium works by swelling and absorbing water when it comes into contact with gastrointestinal fluids. This swelling leads to the rapid disintegration of the tablet or capsule matrix, facilitating the release and absorption of the active pharmaceutical ingredients.

Pharmacodynamics

Croscarmellose sodium is classified as a superdisintegrant. Its ability to rapidly disintegrate solid dosage forms can significantly enhance the dissolution rate of the active ingredient, which is crucial for achieving therapeutic effects in a timely manner.

Pharmacokinetics

Croscarmellose sodium is not absorbed in the gastrointestinal tract and does not exert pharmacological effects in the body. It is considered non-toxic and is excreted unchanged. Its main role is as an excipient, influencing the formulation's characteristics rather than the pharmacokinetics of the active ingredients.

Precautions

• Use with caution in patients with known hypersensitivity to croscarmellose or its components.

Pregnancy

Safety in pregnancy has not been established. Use only if clearly needed.

Breast-feeding

Caution is advised when using during breastfeeding, as safety has not been established.

Formulations

• Powder
• Granules

Indications

• Monitoring respiratory function
• Assessment of metabolic status
• Management of respiratory acidosis
• Management of respiratory alkalosis

Dosage

Children: Dosing for interventions related to carbon dioxide levels in pediatric patients should be guided by clinical protocols and the BNF for Children.

Adults: Dosing for interventions related to carbon dioxide levels is typically based on clinical assessment and individual patient needs. Refer to clinical guidelines for specific scenarios.

Mechanism of action

Carbon dioxide acts primarily as a signaling molecule in the body, influencing respiratory drive and blood pH. It is produced during cellular respiration and is a critical component of the bicarbonate buffering system, which helps maintain acid-base homeostasis. Elevated levels of CO2 in the blood stimulate ventilation in the lungs, increasing the rate of gas exchange and facilitating the removal of excess CO2.

Pharmacodynamics

The pharmacodynamic effects of dioxides, particularly carbon dioxide, are closely related to its concentration in the blood. As CO2 levels increase, it leads to respiratory acidosis, which can stimulate the respiratory centers in the brain to increase ventilation. Conversely, low levels of CO2 can cause respiratory alkalosis, potentially leading to decreased respiratory drive. CO2 also plays a role in vasodilation and can affect blood flow and pressure through its influence on smooth muscle tone.

Pharmacokinetics

Carbon dioxide is produced endogenously during metabolic processes and is transported in the bloodstream primarily in three forms: dissolved in plasma, as bicarbonate ions (HCO3-), and bound to hemoglobin. The half-life of CO2 in the bloodstream is very short due to its rapid exchange with alveolar gas in the lungs. The elimination of CO2 occurs through exhalation, making it a dynamic component of respiratory physiology.

Pregnancy

Data on the effects of dioxide during pregnancy are limited. Caution is advised due to potential risks associated with exposure.

Breast-feeding

Limited data are available regarding the excretion of dioxide in human milk. Caution is recommended.

Storage

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

Dosage

Children: Refer to specific product guidelines as hydroxypropyl is typically used as an excipient and not dosed independently.

Adults: Refer to specific product guidelines as hydroxypropyl is typically used as an excipient and not dosed independently.

Mechanism of action

Hydroxypropyl functions primarily as a solubilizing agent, which aids in the dissolution of poorly soluble drugs. It interacts with water and other solvents to improve the dispersion of pharmaceutical compounds, thereby enhancing their bioavailability. Hydroxypropyl may also facilitate the permeability of drug molecules through biological membranes, contributing to their overall efficacy.

Pharmacodynamics

The pharmacodynamics of hydroxypropyl relate to its role in improving the physicochemical properties of drug formulations. By increasing solubility and stability, hydroxypropyl can enhance the absorption of drugs administered via various routes, including oral and topical. Its non-toxic nature allows for safe incorporation into formulations, making it suitable for a wide range of applications.

Pharmacokinetics

The pharmacokinetics of hydroxypropyl have not been extensively studied as it primarily acts as an excipient rather than an active pharmaceutical ingredient. When used in formulations, it is typically not absorbed into systemic circulation in significant amounts, thereby minimizing potential systemic effects. Hydroxypropyl is generally regarded as safe when used in appropriate amounts in drug formulations.

Pregnancy

Hydroxypropyl is not classified for use during pregnancy, and its safety has not been established. Caution is advised.

Breast-feeding

Indications

• Lactose intolerance
• As a filler or excipient in pharmaceutical formulations

Dosage

Children: Refer to the BNF for Children for specific dosing information based on age and clinical context.

Adults: Refer to the BNF for specific dosing information based on clinical context.

Mechanism of action

Lactose is metabolized in the intestine by the enzyme lactase into its constituent monosaccharides, glucose and galactose. In individuals with lactase deficiency, unabsorbed lactose passes into the colon, where it is fermented by bacteria, leading to gas production and osmotic effects that contribute to diarrhea.

Pharmacodynamics

The pharmacodynamics of lactose are primarily related to its effects on gastrointestinal function. In healthy individuals, lactose is effectively broken down into glucose and galactose, which are absorbed and utilized for energy. In individuals with lactose intolerance, the unabsorbed lactose can cause osmotic diarrhea and colonic fermentation, leading to discomfort and symptoms associated with lactose intolerance.

Pharmacokinetics

Lactose is not absorbed in the gastrointestinal tract until it is hydrolyzed into glucose and galactose by lactase. The absorption of glucose and galactose occurs in the small intestine. The half-life is not applicable as lactose is not typically administered as a medication but is rather ingested as a natural component of food. Its metabolism primarily occurs in the intestine.

Adverse effects

• Bloating
• Diarrhea
• Abdominal pain
• Flatulence

Precautions

• Use with caution in patients with lactose intolerance.
• Consider potential for gastrointestinal upset in sensitive individuals.

Pregnancy

Lactose is generally considered safe for use during pregnancy. However, consult a healthcare professional for individual advice.

Breast-feeding

Lactose is safe to use while breastfeeding, as it is a natural sugar present in breast milk.

Storage

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

Indications

• Nutritional support
• Source of carbohydrates
• Dietary fiber source
• Animal feed

Dosage

Children: As with adults, there are no specific dosing recommendations for maize for children. It can be introduced into the diet in age-appropriate forms and quantities, keeping in mind the overall dietary balance.

Adults: There are no specific dosing recommendations for maize as it is typically consumed as part of a balanced diet. It can be included in daily meals in various forms such as whole kernels, flour, or as part of dishes.

Mechanism of action

Maize primarily acts as a source of energy due to its high carbohydrate content. The complex carbohydrates in maize are broken down into glucose, which is then utilized by the body for energy production. It also contributes to dietary fiber intake, which can aid in digestive health and regulation of blood sugar levels.

Pharmacodynamics

The consumption of maize influences blood glucose and insulin levels due to its carbohydrate content. It has a relatively low glycemic index when consumed in whole form, which can help in managing blood sugar levels. The dietary fiber present in maize can also promote satiety and aid in weight management.

Pharmacokinetics

The digestion of maize begins in the mouth with salivary amylase breaking down starches into simpler sugars. In the stomach and small intestine, enzymes further break down these carbohydrates. The resultant glucose is absorbed into the bloodstream, where it is transported to cells for energy production. The absorption rate can vary based on the form of maize consumed (e.g., whole kernels versus processed forms).

Pregnancy

Maize is generally considered safe for consumption during pregnancy as it is a staple food and provides essential nutrients.

Breast-feeding

Mechanism of action

Pregelatinised starch acts primarily as a thickening agent and binder in pharmaceutical formulations. When mixed with water, it swells and forms a gel-like consistency, which helps in the uniform distribution of active ingredients and enhances their release and absorption in the gastrointestinal tract. Its ability to gel enables better disintegration of tablets upon administration, facilitating the dissolution of the drug.

Pharmacodynamics

The pharmacodynamics of pregelatinised starch is closely related to its physical properties as a polymer. Upon contact with water, it hydrates and expands, creating a viscous solution that can improve the release profile of drugs. This can lead to enhanced dissolution rates of poorly soluble compounds, improving their bioavailability. Additionally, it can impact the stability and shelf-life of formulations by providing a protective matrix for active ingredients.

Pharmacokinetics

Pregelatinised starch is not absorbed systemically as it primarily acts as an excipient. It undergoes gastrointestinal transit without significant degradation. Its function is to facilitate the release and absorption of the active pharmaceutical ingredients in the formulation rather than exhibiting pharmacokinetic properties of its own.

Pregnancy

Pregelatinised starch is generally considered safe for use during pregnancy, but it is recommended to consult a healthcare provider before use.

Mechanism of action

Tinidazole is a prodrug and antiprotozoal agent. The nitro group of tinidazole is reduced in <i>Trichomonas</i> by a ferredoxin-mediated electron transport system. The free nitro radical generated as a result of this reduction is believed to be responsible for the antiprotozoal activity. It is suggested that the toxic free radicals covalently bind to DNA, causing DNA damage and leading to cell death. The mechanism by which tinidazole exhibits activity against <i>Giardia</i> and <i>Entamoeba</i> species is not known, though it is probably similar. The nitro group of tinidazole is reduced by cell extracts of Trichomonas. As a result of this reduction a free nitro radical is generated which may be responsible for the antiprotozoal activity. The mechanism by which tinidazole exhibits activity against Giardia and Entamoeba species is not known.

Pharmacodynamics

Tinidazole is a synthetic antiprotozoal agent. Tinidazole demonstrates activity both in vitro and in clinical infections against the following protozoa: <i>Trichomonas vaginalis</i>, <i>Giardia duodenalis</i> (also termed <i>G. lamblia</i>), and <i>Entamoeba histolytica</i>. Tinidazole does not appear to have activity against most strains of vaginal lactobacilli.

Mechanism of action

It has very good absorptive properties.
