Children: Refer to dietary guidelines for children; beans can be introduced as a protein source in appropriate serving sizes based on age and dietary recommendations.

Adults: Refer to dietary guidelines for general consumption; beans can be included in daily meals as a primary protein source, with recommended servings varying based on dietary needs.

Mechanism of action

Beans exert their health benefits primarily through their high fiber content, which can improve digestion and glucose metabolism. They also contain phytochemicals, such as polyphenols and saponins, that may have antioxidant properties and can help reduce inflammation. Additionally, the protein in beans contributes to muscle repair and maintenance.

Pharmacodynamics

The consumption of beans has been associated with a variety of health benefits. Their high fiber content aids in the regulation of blood sugar levels, lowers cholesterol levels, and promotes satiety, which can be beneficial for weight management. The presence of antioxidants in beans helps to combat oxidative stress and inflammation in the body.

Pharmacokinetics

Beans are digested in the gastrointestinal tract, where dietary fibers are fermented by gut microbiota, producing short-chain fatty acids that are beneficial for colon health. The protein undergoes digestion in the stomach and small intestine, with amino acids being absorbed into the bloodstream. The absorption rate may vary depending on the type of bean and preparation method.

Mechanism of action

Butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) act as antioxidants by inhibiting the oxidation of lipids. They scavenge free radicals and donate hydrogen atoms to reactive species, thus stabilizing and preventing oxidative damage to cellular components. This action helps to protect the integrity of cell membranes and prevent the formation of harmful peroxides.

Pharmacodynamics

The pharmacodynamic properties of butylated compounds are primarily related to their antioxidant activity. They exhibit a dose-dependent ability to inhibit lipid peroxidation, which is crucial in protecting cells from oxidative stress. Furthermore, they may modulate certain biochemical pathways involved in cell signaling and apoptosis, although these effects are less well-characterized.

Pharmacokinetics

Butylated compounds are absorbed from the gastrointestinal tract following oral ingestion. They undergo metabolic processing primarily in the liver, where they are conjugated and excreted in urine. The half-life of butylated compounds in humans is variable, influenced by factors such as dosage and individual metabolism. Accumulation in tissues is generally low, but prolonged exposure may lead to higher tissue concentrations.

Adverse effects

• Gastrointestinal disturbances
• Allergic reactions
• Potential carcinogenic effects with prolonged exposure

Precautions

• Use with caution in patients with a history of hypersensitivity to butylated compounds
• Avoid prolonged exposure due to potential toxicity

Pregnancy

Limited data available, use only if the benefits outweigh the risks.

Breast-feeding

Formulations

• Butylated hydroxytoluene (BHT)
• Butylated hydroxyanisole (BHA)

Indications

• Vitamin D deficiency
• Rickets
• Osteomalacia
• Osteoporosis
• Hypoparathyroidism

Dosage

Adults: The usual adult dose for vitamin D deficiency is 800 to 2000 IU daily, depending on the severity of deficiency and clinical condition. Higher doses may be used under medical supervision.

Mechanism of action

Cholecalciferol is converted to its active forms, 25-hydroxyvitamin D in the liver and 1,25-dihydroxyvitamin D in the kidneys. These metabolites enhance the intestinal absorption of calcium and phosphorus, increase serum calcium levels, and mobilize these minerals from bone. This process is regulated by parathyroid hormone, which influences calcium and phosphate metabolism, particularly in the kidneys.

Pharmacodynamics

The pharmacodynamics of cholecalciferol involve its conversion to active metabolites that play a significant role in calcium and phosphorus homeostasis. The metabolites facilitate intestinal absorption of these minerals, promote bone mineralization, and influence renal reabsorption. The onset of action occurs within 10 to 24 hours following administration, as metabolic activation is required for its biological effects.

Pharmacokinetics

Cholecalciferol is absorbed in the gastrointestinal tract, and its absorption is enhanced by the presence of dietary fats. It is transported in the bloodstream bound to vitamin D-binding protein. Once in the liver, it undergoes hydroxylation to form 25-hydroxyvitamin D, which is further converted in the kidneys to the active form, 1,25-dihydroxyvitamin D. The elimination half-life of cholecalciferol varies, typically spanning several days, and it is primarily excreted in bile and urine.

Adverse effects

• Hypercalcemia
• Hypercalciuria
• Nausea
• Vomiting
• Constipation
• Weakness
• Fatigue

Interactions

• May enhance the effects of thiazide diuretics, leading to increased risk of hypercalcemia
• Anticonvulsants may increase metabolism of vitamin D, leading to reduced effectiveness
• Cholestyramine may reduce absorption of vitamin D

Precautions

• Monitor serum calcium levels in patients with renal impairment
• Caution in patients with a history of hypercalcemia or hyperparathyroidism
• Use with caution in patients taking other medications that affect calcium metabolism

Pregnancy

Cholecalciferol can be used during pregnancy if indicated, as vitamin D is essential for fetal bone development.

Breast-feeding

Cholecalciferol is excreted in breast milk, but is generally considered safe during breastfeeding.

Storage

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

Formulations

• Capsules
• Tablets
• Liquid formulations

Indications

• Head lice infestation
• Body lice infestation
• Scabies

Dosage

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

Adults: Refer to BNF for specific dosing information.

Mechanism of action

Benzyl alcohol, a component of hydroxytoluene, inhibits lice from closing their respiratory spiracles. This action allows the vehicle to obstruct the spiracles, leading to asphyxiation of the lice.

Pharmacodynamics

The pharmacodynamics of hydroxytoluene involves its local anesthetic properties and its ability to disrupt the respiratory function of certain parasites. It exerts its effects primarily on ectoparasites like lice, leading to their death through suffocation. Its effectiveness is facilitated by its lipophilicity, which allows it to penetrate the cuticle of the lice and interfere with their respiratory system.

Pharmacokinetics

Hydroxytoluene is absorbed through the skin when applied topically. Its pharmacokinetic profile is influenced by its formulation, with variations in absorption rates based on the vehicle used. Once absorbed, it undergoes metabolic processes primarily in the liver, where it may be conjugated and excreted in urine. The elimination half-life and specific metabolic pathways are not well defined, requiring further research for comprehensive understanding.

Pregnancy

Hydroxytoluene should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Breast-feeding

Caution is advised when administering hydroxytoluene during breastfeeding due to limited data on its excretion in human milk.

Storage

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

Indications

• Calcium deficiency
• Osteoporosis prevention
• Osteomalacia
• Rickets
• Paget's disease
• Hypoparathyroidism

Dosage

Children: Refer to specific product guidelines or consult a healthcare professional for appropriate dosing.

Adults: Refer to specific product guidelines or consult a healthcare professional for appropriate dosing.

Mechanism of action

The calcium carbonate found in shells acts as a calcium supplement, which is essential for many physiological functions, including bone formation and maintenance. It provides the necessary calcium ions that play a critical role in various cellular processes, including muscle contraction, neurotransmitter release, and blood coagulation.

Pharmacodynamics

Calcium carbonate is a source of calcium, a vital mineral that maintains bone density and overall bone health. When ingested, it dissociates in the stomach, releasing calcium ions that are absorbed in the intestines. It contributes to the prevention of osteoporosis and can aid in the treatment of calcium deficiencies. The effectiveness of calcium carbonate is influenced by factors such as the presence of food in the stomach, which may enhance its absorption.

Pharmacokinetics

After oral administration, calcium carbonate is dissolved in gastric acid and then absorbed primarily in the small intestine. The rate of absorption can be affected by the presence of food. The peak plasma concentration of calcium typically occurs within 1 to 3 hours post-ingestion. The elimination half-life of calcium varies, as it is stored in the bones and slowly released back into circulation. The body regulates calcium levels through hormonal control involving parathyroid hormone and calcitonin.

Pregnancy

Consult a healthcare provider for guidance, as safety during pregnancy may vary based on specific shellfish.

Breast-feeding

Consult a healthcare provider for guidance, as safety during breastfeeding may vary based on specific shellfish.

Storage

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

Indications

• Management of menopausal symptoms
• Cardiovascular health improvement
• Cholesterol reduction
• Dietary protein source
• Potential role in cancer prevention

Dosage

Children: Refer to specific dietary guidelines and recommendations for children, as soya products can be part of a balanced diet.

Adults: Refer to specific dietary guidelines as soya is primarily consumed as a food source rather than a pharmacological agent.

Mechanism of action

Soya exerts its effects primarily through its isoflavones, which are phytoestrogens that can bind to estrogen receptors in the body. This action can modulate estrogen activity, leading to various physiological effects, such as alleviating menopausal symptoms and influencing lipid metabolism. Additionally, the protein in soya can help lower cholesterol levels and improve cardiovascular health by enhancing endothelial function and reducing inflammation.

Pharmacodynamics

The pharmacodynamics of soya is largely attributed to its isoflavone content, including genistein and daidzein. These compounds can mimic estrogen and may exert both estrogenic and anti-estrogenic effects depending on the tissue type. The consumption of soya has been associated with improvements in lipid profiles, reductions in blood pressure, and potential protective effects against certain cancers, particularly hormone-dependent cancers.

Pharmacokinetics

The bioavailability of isoflavones from soya varies but is generally well-absorbed following consumption. After ingestion, isoflavones undergo extensive metabolism in the liver and intestines, leading to the formation of various metabolites that can be detected in the plasma. The elimination half-life of these metabolites varies, but they are typically cleared from the body within hours to a few days, depending on individual metabolism and the amount consumed.

Mechanism of action

Most individuals naturally generate adequate amounts of vitamin D through ordinary dietary intake of vitamin D (in some foods like eggs, fish, and cheese) and natural photochemical conversion of the vitamin D3 precursor 7-dehydrocholesterol in the skin via exposure to sunlight. Conversely, vitamin D deficiency can often occur from a combination of insufficient exposure to sunlight, inadequate dietary intake of vitamin D, genetic defects with endogenous vitamin D receptor, or even severe liver or kidney disease. Such deficiency is known for resulting in conditions like rickets or osteomalacia, all of which reflect inadequate mineralization of bone, enhanced compensatory skeletal demineralization, resultant decreased calcium ion blood concentrations, and increases in the production and secretion of parathyroid hormone. Increases in parathyroid hormone stimulate the mobilization of skeletal calcium and the renal excretion of phosphorus. This enhanced mobilization of skeletal calcium leads towards porotic bone conditions. Ordinarily, while vitamin D3 is made naturally via photochemical processes in the skin, both itself and vitamin D2 can be found in various food and pharmaceutical sources as dietary supplements. The principal biological function of vitamin D is the maintenance of normal levels of serum calcium and phosphorus in the bloodstream by enhancing the efficacy of the small intestine to absorb these minerals from the diet. At the liver, vitamin D3 or D2 is hydroxylated to 25-hydroxyvitamin D and then finally to the primary active metabolite 1,25-dihydroxyvitamin D in the kidney via further hydroxylation. This final metabolite binds to endogenous vitamin d receptors, which results in a variety of regulatory roles - including maintaining calcium balance, the regulation of parathyroid hormone, the promotion of the renal reabsorption of calcium, increased intestinal absorption of calcium and phosphorus, and increased calcium and phosphorus mobilization of calcium and phosphorus from bone to plasma to maintain balanced levels of each in bone and the plasma. In particular, calcitriol interacts with vitamin D receptors in the small intestine to enhance the efficiency of intestinal calcium and phosphorous absorption from about 10-15% to 30-40% and 60% increased to 80%, respectively. Furthermore, calcitriol binds with vitamin D receptors in osteoblasts to stimulate a receptor activator of nuclear factor kB ligand (or RANKL) which subsequently interacts with receptor activator of nuclear factor kB (NFkB) on immature preosteoclasts, causing them to become mature bone-resorbing osteoclasts. Such mature osteoclasts ultimately function in removing calcium and phosphorus from bone to maintain blood calcium and phosphorus levels. Moreover, calcitriol also stimulates calcium reabsorption from the glomerular filtrate in the kidneys. Additionally, it is believed that when calcitriol binds with nuclear vitamin D receptors, that this bound complex itself binds to retinoic acid X receptor (RXR) to generate a heterodimeric complex that consequently binds to specific nucleotide sequences in the DNA called vitamin D response elements. When bound, various transcription factors attach to this complex, resulting in either up or down-regulation of the associated gene's activity. It is thought that there may be as much as 200 to 2000 genes that possess vitamin D response elements or that are influenced indirectly to control a multitude of genes across the genome. It is in this way that cholecalciferol is believed to function in regulating gene transcription associated with cancer risk, autoimmune disorders, and cardiovascular disease linked to vitamin D deficiency. In fact, there has been some research to suggest calcitriol may also be able to prevent malignancies by inducing cellular maturation and inducing apoptosis and inhibiting angiogenesis, exhibit anti-inflammatory effects by inhibiting foam cell formation and promoting angiogenesis in en

Pharmacodynamics

The in vivo synthesis of the predominant two biologically active metabolites of vitamin D occurs in two steps. The first hydroxylation of vitamin D3 cholecalciferol (or D2) occurs in the liver to yield 25-hydroxyvitamin D while the second hydroxylation happens in the kidneys to give 1, 25-dihydroxyvitamin D. These vitamin D metabolites subsequently facilitate the active absorption of calcium and phosphorus in the small intestine, serving to increase serum calcium and phosphate levels sufficiently to allow bone mineralization. Conversely, these vitamin D metabolites also assist in mobilizing calcium and phosphate from bone and likely increase the reabsorption of calcium and perhaps also of phosphate via the renal tubules. There exists a period of 10 to 24 hours between the administration of cholecalciferol and the initiation of its action in the body due to the necessity of synthesis of the active vitamin D metabolites in the liver and kidneys. It is parathyroid hormone that is responsible for the regulation of such metabolism at the level of the kidneys.
