Indications

• Vitamin C deficiency
• Scurvy
• Collagen-related disorders
• Skin health improvement
• Immune system support

Dosage

Children: Pediatric dosing should be based on weight and age, and it is essential to consult the BNF for Children for specific recommendations.

Adults: General adult dosing recommendations should be referred to established guidelines or pharmacological references.

Mechanism of action

Acetateascorbic acts as a potent antioxidant, scavenging free radicals and reducing oxidative stress in tissues. It also plays a crucial role in the hydroxylation of proline and lysine residues in collagen, which is essential for maintaining the structural integrity of connective tissues. The presence of acetate may enhance its stability and bioavailability compared to standard ascorbic acid.

Pharmacodynamics

The pharmacodynamic effects of acetateascorbic primarily stem from its antioxidant activity and its involvement in collagen biosynthesis. The compound helps in reducing the risk of cellular damage by neutralizing reactive oxygen species. Its role in collagen synthesis contributes to tissue repair, wound healing, and overall skin health. Additionally, it may modulate immune responses, aiding in the prevention of infections.

Pharmacokinetics

Acetateascorbic is absorbed through the gastrointestinal tract, with peak plasma concentrations occurring within 2 hours after administration. The compound is widely distributed throughout the body and is concentrated in the adrenal glands, pituitary gland, and leukocytes. It is metabolized primarily in the liver and excreted in urine. The elimination half-life is approximately 30 minutes to 2 hours, depending on the dose and the individual's health status.

Dosage

Children: Refer to the BNF for Children for specific dosing recommendations based on the child's age and condition.

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

Mechanism of action

Acid thiamine acts as a coenzyme for several important enzymes, including pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase. These enzymes are crucial for the metabolism of carbohydrates and the conversion of pyruvate to acetyl-CoA, which is a key step in energy production. Thiamine also plays a role in the synthesis of neurotransmitters, particularly acetylcholine, which is vital for nerve function.

Pharmacodynamics

Thiamine is absorbed in the gastrointestinal tract and is distributed throughout the body, particularly in the heart, liver, and kidneys. It exerts its effects by facilitating metabolic processes that convert carbohydrates into energy, thus preventing the accumulation of pyruvate and lactate. A deficiency in thiamine can lead to neurological symptoms and metabolic disorders, such as Wernicke's encephalopathy and Beriberi.

Pharmacokinetics

Acid thiamine is rapidly absorbed from the gastrointestinal tract, with peak plasma concentrations occurring within 1-2 hours after oral administration. It is primarily excreted in the urine as thiamine and its metabolites. The half-life of thiamine in the body is relatively short, typically around 1-2 hours, necessitating regular dietary intake to maintain adequate levels.

Pregnancy

Acidthiamine is generally considered safe during pregnancy, but it is advised to consult a healthcare provider before use.

Breast-feeding

Acidthiamine is excreted in breast milk; caution should be exercised and a healthcare provider should be consulted.

Storage

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

Formulations

• Tablets
• Injectable solution

Indications

• Riboflavin deficiency
• Pyridoxine deficiency
• Supplementation in conditions affecting absorption or increased metabolic demand
• Supportive therapy in certain neurological disorders

Dosage

Adults: Refer to established guidelines and clinical protocols for specific dosing

Mechanism of action

Riboflavin is a precursor of coenzymes (FMN and FAD) involved in redox reactions, crucial for the metabolism of carbohydrates, fats, and proteins. Pyridoxine is converted to pyridoxal phosphate, a coenzyme that plays a vital role in amino acid metabolism, neurotransmitter synthesis, and the metabolism of glycogen. Together, these vitamins support cellular function and energy metabolism.

Pharmacodynamics

Riboflavin supports the body's energy production through its role in the electron transport chain and as a cofactor in enzymatic reactions. Pyridoxine is essential for the synthesis of neurotransmitters such as serotonin, dopamine, and gamma-aminobutyric acid (GABA), influencing mood and cognitive function. Adequate levels of these vitamins are necessary for maintaining normal physiological processes and overall health.

Pharmacokinetics

Riboflavin is absorbed in the small intestine, primarily in the duodenum and jejunum, with absorption being facilitated by active transport. It is distributed throughout the body and excreted in urine as riboflavin and its metabolites. Pyridoxine is also absorbed in the small intestine, with high bioavailability. It is converted to its active form, pyridoxal phosphate, in the liver and other tissues. Both vitamins have a relatively short half-life, and excess amounts are typically excreted in urine.

Pregnancy

Riboflavin (Vitamin B2) and pyridoxine (Vitamin B6) are generally considered safe during pregnancy. However, it is advisable to consult a healthcare provider for individual circumstances.

Breast-feeding

Both riboflavin and pyridoxine are excreted in breast milk and are considered safe for breastfeeding mothers. Consultation with a healthcare provider is recommended.

Storage

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

Indications

• Pain management
• Anxiety disorders
• Depression
• Attention-deficit hyperactivity disorder (ADHD)
• Substance use disorders
• Certain types of cancer

Dosage

Children: Refer to BNF for Children for specific paediatric dosing information as it varies widely among synthetic drugs.

Adults: Refer to specific product guidelines or BNF for dosing information as it varies widely among synthetic drugs.

Mechanism of action

Synthetic drugs can act through various mechanisms depending on their structure and intended use. They may function by inhibiting or activating specific receptors, modulating enzyme activity, or affecting neurotransmitter levels in the brain. For example, some synthetic opioids bind to the mu-opioid receptors in the central nervous system, producing analgesic effects.

Pharmacodynamics

The pharmacodynamics of synthetic drugs varies widely based on their chemical composition and target receptors. Generally, these drugs can produce a range of effects from sedation and analgesia to stimulation and increased energy. The potency and efficacy of synthetic drugs depend on their affinity for specific receptors and their ability to cross biological membranes.

Pharmacokinetics

Pharmacokinetics of synthetic drugs involves absorption, distribution, metabolism, and excretion (ADME). These drugs are typically well absorbed after administration, with bioavailability varying by route. They may be extensively metabolized in the liver, often resulting in active metabolites. Elimination half-lives can differ significantly, affecting dosing regimens and potential accumulation in the body.

Pregnancy

The safety of synthetic compounds during pregnancy varies widely. Always assess the specific compound and consult relevant guidelines.

Breast-feeding

The safety of synthetic compounds during breastfeeding depends on the specific compound. Consult relevant guidelines for each individual case.

Storage

Store in a cool, dry place, away from direct sunlight. Specific storage conditions may vary based on the individual compound.
