COSMOFER

Indications

• Hypovolemia
• Surgical fluid management
• Trauma
• As an adjunct in severe burns
• Increased blood viscosity conditions

Dosage

Children: Refer to appropriate pediatric dosing guidelines based on clinical condition and patient response. Consult appropriate medical references for exact dosing.

Adults: Refer to specific dosing guidelines based on clinical condition and patient response. Consult appropriate medical references for exact dosing.

Mechanism of action

Dextran complex acts by increasing the osmotic pressure in the blood plasma, which helps to draw fluid into the intravascular compartment. This results in an increase in blood volume, enhancing circulation and improving tissue perfusion. Additionally, dextran has a mild anticoagulant effect due to its ability to inhibit platelet aggregation and reduce blood viscosity.

Pharmacodynamics

The pharmacodynamic effects of dextran complex include increased plasma volume, improved blood circulation, and reduced blood viscosity. It helps maintain hemodynamic stability in patients experiencing significant blood loss or low blood volume. The anticoagulant properties may also contribute to a reduced risk of thromboembolic events.

Pharmacokinetics

Dextran complex is administered intravenously and exhibits a rapid distribution in the vascular compartment. The half-life can vary based on the molecular weight of the dextran used. Generally, dextran is metabolized by the reticuloendothelial system, primarily the liver, and is eventually excreted via the kidneys. The effects of dextran can last from several hours to days, depending on the dosage and the patient's physiological state.

Contra-indications

• Hypersensitivity to dextran or any component of the formulation
• Severe renal impairment
• Congestive heart failure
• Active bleeding disorders

Adverse effects

• Allergic reactions
• Hypotension
• Fluid overload
• Headache
• Nausea
• Vomiting
• Fever

Interactions

• May enhance the effects of anticoagulants
• Potentially interacts with other blood products or volume expanders

Precautions

• Use with caution in patients with renal impairment
• Monitor for signs of fluid overload, especially in elderly patients or those with heart conditions
• Consider monitoring coagulation parameters in patients on anticoagulant therapy

Pregnancy

Safety during pregnancy has not been established; use only if clearly needed.

Breast-feeding

Limited data available; use with caution and monitor for any adverse effects in the infant.

Storage

Store at room temperature, away from light. Do not freeze.

Formulations

• Dextran 40 solution
• Dextran 70 solution

Indications

• Nutritional deficiencies
• Anemia (iron deficiency)
• Bone health (calcium, vitamin D)
• Immune support (zinc, vitamin C)
• Metabolic disorders (B vitamins)

Dosage

Children: Refer to specific paediatric guidelines or consult a healthcare professional for recommended dietary allowances or supplementation based on the child's age, nutritional requirements, and health status.

Adults: Refer to specific guidelines or consult a healthcare professional for recommended dietary allowances or supplementation based on individual needs and health status.

Mechanism of action

Elemental substances function through various mechanisms depending on their type. For example, iron is essential for hemoglobin formation, enabling oxygen transport in the blood. Zinc plays a role in over 300 enzymatic reactions, affecting metabolism, immune function, and DNA synthesis. Vitamins act as coenzymes or precursors in metabolic pathways, facilitating biochemical reactions necessary for cellular function.

Pharmacodynamics

The pharmacodynamics of elemental substances vary widely. Minerals such as calcium and phosphorus are crucial for bone health, while potassium is vital for maintaining normal cellular function and electrical activity of the heart. Vitamins such as vitamin C have antioxidant properties, protecting cells from oxidative damage, while B vitamins are integral to energy metabolism. The effects of these elements are often dose-dependent, with both deficiencies and excesses leading to adverse health outcomes.

Pharmacokinetics

The pharmacokinetics of elemental substances involve their absorption, distribution, metabolism, and excretion. Minerals are typically absorbed in the gastrointestinal tract, with absorption rates influenced by dietary factors and the presence of other nutrients. For example, vitamin D enhances calcium absorption. Once absorbed, these elements are distributed throughout the body via the bloodstream, utilized by various tissues, or stored in organs such as the liver and bones. Excretion occurs primarily through urine and feces, with some elements having specific pathways for elimination.

Pregnancy

Consult a healthcare provider before use, as safety in pregnancy is not well established.

Breast-feeding

Consult a healthcare provider before use, as the effects on breastfed infants are not well documented.

Storage

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

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.
