ALC GLUCOSAMINE TABLETS

Indications

• Symptomatic relief of mild to moderate osteoarthritis of the knee

Dosage

Children: Refer to the BNF for Children for

Adults: 200–400 mg daily, maximum 6.5 mg/kg per day, or 1250 mg once daily, or 1500 mg once daily dissolved in at least 250 mL of water; review treatment if no benefit after 2–3 months.

Mechanism of action

The mechanism of action of glucosamine in joint health is not entirely clear, but it is believed to involve several pathways. Glucosamine is a precursor for glycosaminoglycans, which are essential for cartilage integrity. It may also reduce inflammation by inhibiting interferon gamma and Nuclear factor kappa B subunit 65 (NF-κB p65), which could improve symptoms of arthritis and joint pain. Upon uptake by living cells, glucosamine reacts with ATP to form glucosamine-6-phosphate, further contributing to glycosaminoglycan synthesis.

Pharmacodynamics

Glucosamine is theorized to provide essential building blocks for the synthesis of glycosaminoglycans, potentially slowing the progression of osteoarthritis and alleviating joint pain. Although some studies have indicated modest improvements in joint pain and function among users, the overall evidence remains inconclusive. Glycosaminoglycans are critical for maintaining cartilage elasticity, strength, and flexibility, which are vital for joint health.

Pharmacokinetics

After oral administration, glucosamine is absorbed in the gastrointestinal tract and transported into the bloodstream, where it is metabolized into various forms, including glucosamine-6-phosphate. The exact pharmacokinetics, such as absorption rate and half-life, remain largely undefined, and much of the data is derived from animal studies. Further research is required to clarify its pharmacokinetic profiles in humans.

• Occipital Horn Syndrome
• Menke's disease
• Contraception (via copper IUD)

Dosage

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

Adults: Refer to the relevant clinical guidelines and BNF for specific dosing information.

Mechanism of action

Copper is absorbed from the gastrointestinal tract via high affinity copper uptake proteins and low affinity copper uptake proteins, likely being reduced to the Cu1+ form prior to transport. Inside enterocytes, it binds to the copper transport protein ATOX1, which facilitates its transport to copper transporting ATPase-1 on the Golgi membrane for incorporation into the Golgi apparatus. Once in systemic circulation, copper binds primarily to ceruloplasmin, albumin, and alpha 2-macroglobulin. It acts as a cofactor in a variety of oxidase enzymes and also influences sperm motility when released from copper IUDs, contributing to its contraceptive effect.

Pharmacodynamics

Copper is essential for the activity of many enzymes and plays a vital role in processes such as iron metabolism, neurotransmitter synthesis, and antioxidant defense. Copper ions, particularly when released from intrauterine devices, have been shown to decrease sperm viability, thereby impacting fertility.

Pharmacokinetics

Copper is absorbed from the gut and is predominantly transported in the plasma bound to proteins such as ceruloplasmin and albumin. The absorption efficiency can vary; however, a significant portion of dietary copper is usually absorbed. The body regulates copper levels through hepatic excretion and storage mechanisms, ensuring homeostasis. Excess copper can lead to toxicity, while deficiency results in various health issues.

Pregnancy

Copper is considered essential during pregnancy, but excessive intake should be avoided due to potential toxicity.

Breast-feeding

Mechanism of action

Glycine acts primarily as an inhibitory neurotransmitter in the brain and spinal cord by binding to glycine receptors, which are ligand-gated chloride channels. This binding causes an influx of chloride ions into the neuron, leading to hyperpolarization and decreased neuronal excitability. Additionally, glycine may influence NMDA (N-methyl-D-aspartate) receptor activity, which is implicated in synaptic plasticity and memory function.

Pharmacodynamics

The pharmacodynamics of glycinate are closely tied to its action as a neurotransmitter. Its calming effects can help in reducing anxiety and improving sleep quality. Glycine's ability to modulate neurotransmission makes it a candidate for therapeutic use in various neurological and psychiatric disorders. Furthermore, its role in collagen synthesis and as a precursor to other important biomolecules highlights its significance in metabolic processes.

Pharmacokinetics

Glycine has a relatively low molecular weight and is readily absorbed from the gastrointestinal tract. It is distributed throughout the body and can cross the blood-brain barrier. The metabolism of glycine occurs mainly in the liver, where it can be converted to glucose or other metabolites. It has a short half-life, leading to rapid elimination primarily through the kidneys. The excretion of glycine is influenced by renal function, and dosage adjustments may be necessary in patients with compromised kidney function.

Pregnancy

The safety of glycinate in pregnancy has not been established. Consult a healthcare professional before use in pregnant women.

Breast-feeding

It is not known if glycinate is excreted in human milk. Caution should be exercised when administering to breastfeeding women.

Storage

Dosage

Children: Refer to specific medication guidelines for dosing adjustments due to grapefruit juice interactions.

Adults: Refer to specific medication guidelines for dosing adjustments due to grapefruit juice interactions.

Mechanism of action

Grapefruit juice contains compounds called furanocoumarins, which inhibit cytochrome P450 3A4 (CYP3A4) enzymes in the liver and intestines. This inhibition can lead to increased plasma concentrations of drugs that are metabolized by CYP3A4, resulting in enhanced pharmacological effects and potential toxicity.

Pharmacodynamics

The pharmacodynamic effects of grape juice are closely related to its antioxidant properties, primarily due to resveratrol and flavonoids. These compounds help in reducing oxidative stress and inflammation. However, the primary clinical concern is the modulation of drug metabolism, particularly affecting drugs with a narrow therapeutic index.

Pharmacokinetics

Grapefruit juice can significantly alter the pharmacokinetics of certain medications by affecting their absorption and metabolism. The inhibition of CYP3A4 can lead to increased bioavailability of drugs that are substrates of this enzyme, resulting in higher plasma concentrations. The effects of grapefruit juice can persist for up to 24 hours post-consumption, complicating timing and dosing of affected medications.

Mechanism of action

Many substances termed 'mellow' typically enhance the activity of gamma-aminobutyric acid (GABA) receptors or modulate serotonin and dopamine levels in the brain. By increasing GABAergic transmission, these agents promote sedation and anxiolytic effects, while serotonergic modulation can improve mood and decrease anxiety. This interplay results in an overall calming effect.

Pharmacodynamics

The pharmacodynamic properties of mellow-related compounds often involve anxiolytic effects, mood stabilization, and potential muscle relaxant properties. The efficacy can vary significantly depending on the specific active ingredients and their respective affinities for neurotransmitter receptors. Tolerance and dependency may develop with long-term use, particularly for substances that act on GABA receptors.

Pharmacokinetics

The pharmacokinetics of mellow-related substances depend on the active ingredients. Generally, they may be absorbed through various routes, with oral administration being common. Peak plasma concentrations are usually reached within a few hours, and the half-life can range significantly based on the specific agent. Metabolism often occurs in the liver, and excretion is primarily renal.

Adults: Refer to specific seed type and formulation for dosing information, as it can vary widely based on type and intended use.

Mechanism of action

The bioactive compounds in seeds, such as polyunsaturated fatty acids, phytosterols, and antioxidants, exert various effects in the body. For example, omega-3 fatty acids found in flaxseeds can influence lipid metabolism and reduce inflammation by modulating the production of eicosanoids. Antioxidants such as tocopherols and phenolic compounds can scavenge free radicals, reducing oxidative stress.

Pharmacodynamics

Seeds have shown potential benefits, including the modulation of lipid profiles, reduction in inflammatory markers, and improvement in glycemic control. The consumption of seeds may lead to decreased low-density lipoprotein (LDL) cholesterol levels and increased high-density lipoprotein (HDL) cholesterol levels, contributing to cardiovascular health. The dietary fiber in seeds can also aid in digestive health and promote satiety.

Pharmacokinetics

The pharmacokinetics of seeds can vary widely depending on the type of seed and the specific compounds being analyzed. Generally, the bioactive components are digested and absorbed in the gastrointestinal tract, with fatty acids being incorporated into chylomicrons and transported via the lymphatic system. Antioxidants are absorbed in the small intestine and may have systemic effects, while fiber can influence gastrointestinal motility and fermentation in the colon.

• Pain associated with inflammation

Dosage

Children: Refer to specific formulations and clinical guidelines for dosing recommendations, as serratiopeptidase can vary in concentration and formulation.

Adults: Refer to specific formulations and clinical guidelines for dosing recommendations, as serratiopeptidase can vary in concentration and formulation.

Mechanism of action

Serratiopeptidase operates by breaking down proteins in the body, specifically through the cleavage of peptide bonds. This proteolytic activity helps reduce inflammation by degrading inflammatory mediators and promoting the absorption of exudates (fluid that leaks out of blood vessels) in tissues. Additionally, it may facilitate the breakdown of fibrin, a protein involved in blood clotting, which can help reduce swelling and promote healing.

Pharmacodynamics

The pharmacodynamic effects of serratiopeptidase include its ability to modulate the inflammatory response and enhance tissue healing. By reducing edema and exudate, it helps alleviate pain associated with inflammation and promotes recovery in various conditions involving tissue injury. The anti-inflammatory effects of serratiopeptidase are attributed to its ability to inhibit the synthesis and release of pro-inflammatory cytokines.

Pharmacokinetics

Serratiopeptidase is typically absorbed in the gastrointestinal tract after oral administration. It exhibits a rapid onset of action, with peak plasma concentrations usually occurring within a few hours. The enzyme is metabolized in the liver and eliminated primarily through the kidneys. Its half-life can vary based on individual patient factors and the formulation used.

Mechanism of action

Sulafte works by competitively inhibiting the enzyme dihydropteroate synthase, which is involved in the folate synthesis pathway in bacteria. By blocking this enzyme, sulafte reduces the production of dihydrofolate, a precursor of tetrahydrofolate, which is crucial for the synthesis of purines and ultimately nucleic acids.

Pharmacodynamics

The pharmacodynamics of sulafte involve its bacteriostatic activity, meaning it inhibits the growth and reproduction of bacteria rather than killing them outright. This antibiotic effect is enhanced when combined with other antibacterial agents, such as trimethoprim, leading to synergistic effects against susceptible bacterial strains.

Pharmacokinetics

Sulafte is generally well absorbed after oral administration, with peak plasma concentrations typically occurring within 2 to 4 hours. It is widely distributed throughout body tissues and fluids, including urine, where it achieves high concentrations. The drug is mainly excreted unchanged in the urine, with a half-life that can vary based on renal function. Dosage adjustments may be necessary in patients with impaired renal function.

Mechanism of action

The mechanism of action of glucosamine in joint health is unclear, however there are several possible mechanisms that contribute to its therapeutic effects. Because glucosamine is a precursor for glycosaminoglycans, and glycosaminoglycans are a major component of joint cartilage, glucosamine supplements may help to rebuild cartilage and treat the symptoms of arthritis. Some in vitro studies show evidence that glucosamine reduces inflammation via inhibition of interferon gamma and Nuclear factor kappa B subunit 65 (NF-κB p65), improving the symptoms of arthritis and joint pain. Clinical relevance is unknown at this time. When taken up by living cells, glucosamine reacts with ATP to form glucosamine-6-phosphate, the natural precursor of glycosaminoglycans (GAGs) that contain N-acetylglucosamine (keratan sulfate and Hyaluronan) and those that have N-acetylgalactosamine (heparan sulfate and chondroitin sulfate). These GAGs are polysaccharides composed of hexosamines and monosaccharides (e.g., galactose and glucuronic acid) arranged as a linear chain of repeating disaccharide units (such as the glucuronic acid and N-acetylgalactosamine-6-sulfate of chondroitin sulfate). With the exception of hyaluronan, GAGs do not exist alone in nature but are attached to specific "core" proteins, and the composite structures are called proteoglycans (protein-glycosaminoglycans). Both hyaluronan and many different kinds of proteoglycans (such as aggrecan, versican, and syndecan) are abundant throughout the body where they perform diverse functions.

Pharmacodynamics

The administration of glucosamine, in theory, provides a building block towards the synthesis of glycosaminoglycans, slowing the progression of osteoarthritis and relieving symptoms of joint pain. Studies to this date examining the efficacy of glucosamine sulfate have been inconclusive. Glycosaminoglycans contribute to joint cartilage elasticity, strength, and flexibility. A systematic review of various studies and guidelines determined that modest improvements were reported for joint pain and function in patients taking glucosamine. A consistent joint space narrowing was observed, but with an unclear clinical significance.

Mechanism of action

Copper is absorbed from the gut via high affinity copper uptake protein and likely through low affinity copper uptake protein and natural resistance-associated macrophage protein-2. It is believed that copper is reduced to the Cu1+ form prior to transport. Once inside the enterocyte, it is bound to copper transport protein ATOX1 which shuttles the ion to copper transporting ATPase-1 on the golgi membrane which take up copper into the golgi apparatus. Once copper has been secreted by enterocytes into the systemic circulation it remain largely bound by ceruloplasmin (65-90%), albumin (18%), and alpha 2-macroglobulin (12%). Copper is an essential element in the body and is incorporated into many oxidase enzymes as a cofactor. It is also a component of zinc/copper super oxide dismutase, giving it an anti-oxidant role. Copper defiency occurs in Occipital Horn Syndrome and Menke's disease both of which are associated with impaired development of connective tissue due to the lack of copper to act as a cofactor in protein-lysine-6-oxidase. Menke's disease is also associated with progressive neurological impairment leading to death in infancy. The precise mechanisms of the effects of copper deficiency are vague due to the wide range of enzymes which use the ion as a cofactor. Copper appears to reduce the viabilty and motility of spermatozoa. This reduces the likelihood of fertilization with a copper IUD, producing copper's contraceptive effect. The exact mechanism of copper's effect on sperm are unknown. The reason for the less severe reaction when the foreign body is at a distance from the retina has been proposed to be ... that near the retina & its blood vessels there is greater oxygen tension than at a distance, which causes metallic copper to oxidize to toxic copper compounds more rapidly close to or in contact with the retina than at a distance. Furthermore, the abscess formation that is characteristic of copper undergoing oxidation close to the retina & choroiod can be attributed to attraction of polymorphonuclear leukocytes from these nearby vascular tissues, which become heavily infiltrated. Liquefaction & disorganization of the vitreous body has been explained on the basis of copper catalysis of oxidation of ascorbic acid, leading to depolymerization of the hyaluronic acid of the vitreous humor. Changes in protein & hexosamine content have also been related to decrease in viscosity of the vitreous humor. Increased content of amino acids in the vitreous humor has been consistent with proteolysis of the vitreous body, but decreased concentration in the aqueous humor has suggested suppression of secretion of amino acids by the ciliary body under the influence of copper.

Pharmacodynamics

Copper is incorporated into many enzymes throughout the body as an essential part of their function. Copper ions are known to reduce fertility when released from copper-containing IUDs.
