Indications

• Fluid and electrolyte imbalances
• Hypoglycemia
• Nutritional supplementation
• Diabetic emergencies

Dosage

Children: Refer to the BNF for Children for appropriate paediatric dosing guidelines.

Adults: The dosage varies based on the clinical condition and specific formulation used. For intravenous administration, consult product literature for precise dosing.

Mechanism of action

Glucose supplies energy to tissues by undergoing glycolysis, which begins with its phosphorylation by hexokinase to form glucose 6-phosphate. This activates glucose for breakdown, ultimately generating ATP and NADH. The aerobic metabolism of glucose can yield up to 36 ATP molecules. Glucose also serves as a precursor for other biomolecules and regulates various physiological processes including gene transcription and hormone secretion.

Pharmacodynamics

Glucose is an obligatory energy source for cellular activities and plays a significant role in metabolic signaling. It is oxidized to yield energy through glycolysis, the citric acid cycle, and oxidative phosphorylation. Glucose can be converted into fat for energy storage and is stored as glycogen in the liver and muscles. Its administration increases blood glucose levels and stimulates insulin secretion, particularly through oral routes that activate gut incretin hormones.

Pharmacokinetics

Glucose is rapidly absorbed from the gastrointestinal tract or directly into the bloodstream when administered intravenously. It is distributed widely throughout the body and metabolized primarily in tissues requiring energy. The body maintains glucose homeostasis through regulatory mechanisms involving insulin and glucagon. Excess glucose can be stored as glycogen or converted to triglycerides for long-term energy storage.

Mechanism of action

Methyl parathion acts primarily by inhibiting the enzyme acetylcholinesterase, which is essential for the breakdown of the neurotransmitter acetylcholine. Its active metabolite, methyl paraoxon, is a potent inhibitor of both acetylcholinesterase and butyrylcholinesterase. The inhibition of these enzymes results in the accumulation of acetylcholine at synapses, leading to overstimulation of cholinergic receptors and resultant toxic effects.

Pharmacodynamics

The pharmacodynamics of methyl parathion involve its action as a noncompetitive inhibitor of acetylcholinesterase, causing prolonged effects of acetylcholine due to its inability to be hydrolyzed. The resultant cholinergic toxicity can lead to symptoms such as muscle twitching, respiratory distress, and potentially fatal outcomes if not treated promptly. The extent of inhibition is dose-dependent, with significant toxicity occurring after substantial enzyme inhibition.

Pharmacokinetics

Methyl parathion is absorbed through the gastrointestinal tract and can also be absorbed through the skin and respiratory tract. It is metabolized in the liver to form methyl paraoxon, which is responsible for the majority of its toxic effects. The distribution of methyl parathion in body tissues is influenced by its lipophilicity, and it is primarily excreted as metabolites in the urine. The elimination half-life and specific pharmacokinetic parameters can vary based on individual metabolism and exposure levels.

Mechanism of action

Paracetamol primarily exerts its analgesic and antipyretic effects through the inhibition of cyclooxygenase (COX) enzymes in the brain. This leads to a decrease in the synthesis of prostaglandins, which are mediators of pain and fever. Unlike NSAIDs, paracetamol has minimal anti-inflammatory effects due to its limited action on peripheral COX enzymes.

Pharmacodynamics

Paracetamol produces its analgesic effects by acting centrally in the brain, altering the perception of pain. It also acts on the hypothalamic heat-regulating center to promote vasodilation and sweating, thereby lowering elevated body temperature. The drug does not possess significant anti-inflammatory properties, distinguishing it from other classes of analgesics.

Pharmacokinetics

Paracetamol is rapidly absorbed from the gastrointestinal tract, with peak plasma concentrations typically reached within 30 to 60 minutes after oral administration. It is metabolized primarily in the liver through conjugation with glucuronic acid and sulfate, with a small fraction undergoing oxidation to form a reactive metabolite. The elimination half-life ranges from 1 to 4 hours in healthy individuals. The drug is excreted mainly in urine as its metabolites.

Pregnancy

Children: Refer to established guidelines for specific formulations, as doses may vary depending on the form of peppermint used and the age of the child.

Adults: Refer to established guidelines for specific formulations, as doses may vary depending on the form of peppermint used (e.g., tea, oil, capsules).

Mechanism of action

The primary mechanism of action of peppermint is attributed to menthol, which activates the TRPM8 (transient receptor potential melastatin 8) ion channel, producing a cooling sensation. This action can help relax smooth muscle in the gastrointestinal tract, reduce spasms, and enhance the flow of bile, facilitating digestion. Furthermore, menthol exhibits mild analgesic and anti-inflammatory properties, which contribute to its use in topical applications.

Pharmacodynamics

Peppermint has antispasmodic, carminative, and analgesic properties. It enhances gastrointestinal motility and reduces the perception of pain in the digestive tract. The herb's volatile oil components can influence smooth muscle tone, leading to relaxation and relief from cramping and discomfort. Additionally, peppermint promotes salivation and bile secretion, further aiding digestion.

Pharmacokinetics

Peppermint oil is rapidly absorbed in the gastrointestinal tract following oral administration. The main active components, such as menthol, are metabolized primarily in the liver. The half-life of menthol varies, but it is generally eliminated within a few hours. Topical applications lead to localized effects, with minimal systemic absorption. The pharmacokinetics of peppermint are influenced by factors such as dosage form and individual metabolism.

• Enhancing flavor in food products
• Replacement of carbohydrates in certain medical nutrition therapies

Dosage

Children: Refer to general dietary guidelines for carbohydrate intake in children. No specific dosing guidelines provided.

Adults: Refer to general dietary guidelines for carbohydrate intake. No specific dosing guidelines provided.

Mechanism of action

Sugar is metabolized in the body to provide energy. Upon ingestion, sucrose is broken down by the enzyme sucrase into its constituent monosaccharides, glucose and fructose, which are then absorbed into the bloodstream. These monosaccharides can be utilized by cells for energy or stored as glycogen in the liver and muscles.

Pharmacodynamics

As a simple carbohydrate, sugar elevates blood glucose levels rapidly after consumption, leading to increased insulin secretion from the pancreas. This insulin facilitates the uptake of glucose by tissues, promoting energy production. The rapid increase in blood sugar can provide quick energy but may also lead to potential negative effects on metabolism and weight if consumed in excess.

Pharmacokinetics

After oral administration, sugar is quickly hydrolyzed in the gastrointestinal tract. Peak plasma glucose concentrations typically occur within 30 minutes to 2 hours post-ingestion, depending on the amount consumed and individual metabolism. The half-life of glucose in the bloodstream is relatively short, as it is rapidly taken up by tissues or converted into glycogen.

Pregnancy

Sugar is generally considered safe for use during pregnancy, but excessive intake should be avoided to prevent gestational diabetes and excessive weight gain.

Breast-feeding

Sugar is safe during breastfeeding; however, excessive consumption should be avoided.

Mechanism of action

Glucose supplies most of the energy to all tissues by generating energy molecules ATP and NADH during a series of metabolism reactions called glycolysis. Glycolysis can be divided into two main phases where the preparatory phase is initiated by the phosphorylation of glucose by hexokinase to form glucose 6-phosphate. The addition of the high-energy phosphate group activates glucose for the subsequent breakdown in later steps of glycolysis and is the rate-limiting step. Products end up as substrates for following reactions, to ultimately convert C6 glucose molecule into two C3 sugar molecules. These products enter the energy-releasing phase where the total of 4ATP and 2NADH molecules are generated per one glucose molecule. The total aerobic metabolism of glucose can produce up to 36 ATP molecules. These energy-producing reactions of glucose are limited to D-glucose as L-glucose cannot be phosphorylated by hexokinase. Glucose can act as precursors to generate other biomolecules such as vitamin C. It plays a role as a signaling molecule to control glucose and energy homeostasis. Glucose can regulate gene transcription, enzyme activity, hormone secretion, and the activity of glucoregulatory neurons. The types, number, and kinetics of glucose transporters expressed depends on the tissues and fine-tunes glucose uptake, metabolism, and signal generation to preserve cellular and whole body metabolic integrity. Vascular calcification is a hallmark of type 2 diabetes. Glucose stimulates calcification in culture of vascular smooth muscle cells (VSMCs) but the underlying mechanisms remain obscure. We observed that high glucose levels stimulated mouse and human VSMC trans-differentiation into chondrocytes, with increased levels of Sox9, type II collagen, glycosaminoglycan and Runx2 expression, and increased alkaline phosphatase activity and mineralization. These effects were associated with increased expression of IL-1beta, which stimulated alkaline phosphatase and calcification, suggesting that glucose induces chondrocyte differentiation of VSMCs, possibly through IL-1beta activation.

Pharmacodynamics

Blood glucose is an obligatory energy source for humans involved in various cellular activities, and it also acts as a signaling molecule for diverse glucose-sensing molecules and proteins. Glucose undergoes oxidation into carbon dioxide, water, and yields energy molecules in the process of glycolysis and subsequent citric cycle and oxidative phosphorylation. Glucose is readily converted into fat in the body which can be used as a source of energy as required. Under a similar conversion into storage of energy, glucose is stored in the liver and muscles as glycogen. Glucose stores are mobilized in a regulated manner, depending on the tissues' metabolic demands. Oral glucose tablets or injections serve to increase the supply of glucose and oral glucose administration is more effective in stimulating insulin secretion because it stimulates the incretin hormones from the gut, which promotes insulin secretion.

Mechanism of action

Acute poisoning ... is related to ... inhibiting action on enzyme acetylcholinesterase. Toxic manifestations generally occur only after more than 50% of plasma cholinesterase is inhibited. ... Methyl parathion ... depend on oxidative activation by replacement of thiono-sulfur with oxygen for ... toxicity. Methyl parathion has only a slight inhibitory action on acetylcholinesterase and butyrylcholinesterase, but its active metabolite, methyl paraoxon, is a potent inhibitor of both these enzymes. A study was conducted examining the inhibition of (Ca2+ and Mg2+)-ATPase by parathion (56382) and methyl parathion. Enzyme activity was assessed spectrophotometrically in pig erythrocyte membranes containing calcium2+ (Ca2+) and magnesium2+ and in solubilized membrane preparations incubated with the test agents. The enzyme response to ATP was biphasic. Equations expressing the kinetics of the substrate curves described two classes of the ATP binding active site, one with high affinity and low maximum rate and one with low affinity and high maximum rate. High affinity active sites were stimulated by low ATP concentrations (20 uM), whereas low affinity active sites were stimulated by high ATP levels (2 mM). Parathion and methylparathion dose dependently inhibited enzyme activity; parathion had a greater inhibitory effect than methylparathion. Lineweaver-Burke and Dixon plots indicated noncompetitive inhibition. Parathion and methylparathion induced enzyme inhibition occurred over a range of free calcium ion concentrations (0.5 to 5 mM); the inhibition was significantly greater at lower Ca2+ concentrations (1 to 100 uM) than at higher concentrations. The authors conclude that parathion and methylparathion inhibit ATPase activity by binding to a site on the enzyme rather than through an interaction with associated lipids.
