NEO TABLET

Indications

• Vitiligo
• Hyperpigmentation disorders

Dosage

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

Adults: Refer to BNF for specific dosing guidance.

Mechanism of action

Monobenzone acts as a depigmenting agent through an incompletely understood mechanism. It is suggested that monobenzone increases the excretion of melanin from melanocytes and interferes with the biosynthesis of melanin by inhibiting the enzyme tyrosinase. This inhibition prevents the conversion of tyrosine to dihydroxyphenylalanine, which is a precursor of melanin. As a result, the drug leads to depigmentation, especially in areas with existing hyperpigmentation, while the epidermis remains intact but lacks identifiable melanocytes.

Pharmacodynamics

Monobenzone is the monobenzyl ether of hydroquinone. It functions as a topical agent that permanently removes color from normal skin surrounding areas affected by vitiligo. By inhibiting the production of melanin, monobenzone reduces skin pigmentation and facilitates a more uniform skin tone over time. The effect is particularly pronounced in hyperpigmented skin, which fades more quickly than normal skin.

Pharmacokinetics

The pharmacokinetics of monobenzone are not extensively detailed in available literature. However, it is primarily applied topically, and its systemic absorption is likely minimal. The onset of action can vary, with effects typically observable within one to four months. The drug is metabolized within the skin, and its efficacy can be influenced by factors such as sun exposure, which can reduce its depigmenting effects.

Dosage

Children: Refer to established

Adults: Refer to established guidelines and consult a healthcare professional for recommended doses, as they can vary based on the form of garlic (raw, powdered, aged extract) and the condition being treated.

Mechanism of action

The primary mechanism of action of garlic and its active compounds, especially allicin, involves the modulation of various cellular pathways. Allicin exhibits antimicrobial properties by disrupting the integrity of microbial cell membranes, leading to cell lysis. Additionally, garlic is known to enhance nitric oxide production, which aids in vasodilation, thereby contributing to its cardiovascular benefits. It also influences lipid metabolism and has been shown to reduce levels of LDL cholesterol and triglycerides.

Pharmacodynamics

Garlic's pharmacodynamic effects include its ability to reduce blood pressure, improve lipid profiles, and exert antioxidant effects. It influences various signaling pathways, including those related to inflammation and oxidative stress. The anti-inflammatory effects are mediated through the inhibition of pro-inflammatory cytokines and the modulation of transcription factors such as NF-kB. Garlic also possesses antiplatelet activity, which can contribute to its cardiovascular protective effects.

Pharmacokinetics

The pharmacokinetics of garlic compounds can vary significantly. Allicin, the most studied active component, is rapidly absorbed and metabolized, with its effects being relatively short-lived. After ingestion, allicin is converted into various sulfur-containing compounds, which are responsible for garlic's therapeutic effects. These compounds are distributed throughout the body and are eliminated primarily through urinary excretion. The bioavailability of garlic can be influenced by factors such as preparation methods (raw, cooked, aged extracts) and individual metabolic differences.

Indications

• Adrenal insufficiency
• Chronic inflammatory conditions

Mechanism of action

Glycyrrhizin, the primary active component of Glycyrrhiza, exerts its effects primarily through inhibition of the enzyme 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2). This inhibition prevents the conversion of active cortisol to inactive cortisone, leading to increased cortisol levels. Elevated cortisol mimics the effects of aldosterone, resulting in sodium retention, potassium excretion, and increased blood pressure. Additionally, licorice has anti-inflammatory and antiviral properties attributed to its ability to modulate various immune pathways and inhibit viral replication.

Pharmacodynamics

The pharmacodynamic effects of Glycyrrhiza include anti-inflammatory, antiviral, and immunomodulatory activities. Glycyrrhizin has been shown to reduce inflammation by inhibiting the production of pro-inflammatory cytokines and mediators. Its potential antiviral properties are particularly noted in viral infections such as hepatitis C and COVID-19, where it may inhibit viral replication. Furthermore, its ability to enhance the effects of corticosteroids can be beneficial in treating conditions associated with adrenal insufficiency or chronic inflammation.

Pharmacokinetics

Glycyrrhizin is absorbed from the gastrointestinal tract, with peak plasma concentrations occurring within 1-2 hours after oral administration. It undergoes extensive metabolism in the liver, primarily through conjugation processes, leading to the formation of glycyrrhetic acid as a major metabolite. The elimination half-life of glycyrrhizin is approximately 6-8 hours. Glycyrrhiza components are excreted in urine predominantly as conjugated forms. Long-term use can lead to accumulation and potential side effects due to its mineralocorticoid-like effects.

Mechanism of action

Strychnine is a strong convulsant. The alkaloid excites the CNS by specifically antagonizing the inhibitory neurotransmitter amino acid, glycine, at postsynaptic receptors. Inhibitory glycine receptors are abundant in the spinal cord and brain stem where they are mainly involved in the regulation of motor functions. Strychnine-binding glycine receptors have also been found in the cortex, as well as in the auditory and visual systems. When inhibition is blocked, ongoing neuronal excitability is increased and sensory stimuli produce exaggerated reflex effects. Glycine receptors in higher brain centers such as the substantia nigra, neostriatum, and hippocampus are commonly insensitive to strychnine, explaining why strychnine symptoms are largely spinal in origin. Strychnine can also depress nicotinic-cholinergic responses through interaction with nicotinic receptors and at high concentrations in vitro binds to other receptors as well.

Pharmacodynamics

Strychnine's pharmacodynamic effects are primarily characterized by its convulsant properties. By antagonizing glycine receptors, it leads to increased neuronal excitability, resulting in heightened muscle tone and spasms. This can lead to a series of clinical effects including severe muscle contractions, hyperreflexia, and in high doses, can culminate in respiratory failure and death. The drug's effects are particularly prominent in the spinal cord, influencing motor function and reflex pathways.

Pharmacokinetics

Strychnine is well absorbed when administered orally and is distributed widely throughout the body. It crosses the blood-brain barrier, allowing it to exert its central nervous system effects. The metabolism of strychnine occurs primarily in the liver, and it is excreted via the kidneys. Its half-life and elimination can be influenced by various factors including dosage and individual patient characteristics, but specific pharmacokinetic parameters require further research for precise

Mechanism of action

Vancomycin works by inhibiting bacterial cell wall synthesis. It binds to the D-alanyl-D-alanine terminus of the cell wall precursor units, preventing their incorporation into the growing cell wall. This action disrupts the integrity of the bacterial cell wall, leading to cell lysis and death. Vancomycin is particularly effective against dividing bacteria that are actively synthesizing their cell walls.

Pharmacodynamics

The pharmacodynamics of vancomycin involve its time-dependent killing properties, meaning that the efficacy of the drug is related to the duration of time that serum concentrations exceed the minimum inhibitory concentration (MIC) for the target organism. The drug exhibits bactericidal activity against susceptible organisms, particularly against staphylococci and enterococci. Resistance can develop, particularly with enterococci, if vancomycin is used inappropriately.

Pharmacokinetics

Vancomycin is poorly absorbed from the gastrointestinal tract, which is why oral formulations are used primarily for localized infections like C. difficile. When administered intravenously, it distributes widely into body tissues and fluids. The volume of distribution is approximately 0.4 to 1 L/kg. Vancomycin is primarily eliminated by the kidneys, with a half-life ranging from 4 to 6 hours in individuals with normal renal function. Dosage adjustments may be necessary in patients with renal impairment.

Storage

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

Mechanism of action

Monobenzone is a depigmenting agent whose mechanism of action is not fully understood. It is proposed that it increases the excretion of melanin from the melanocytes. This effect is erratic and may take one to four months to occur while existing melanin is lost with normal sloughing of the stratum corneum. Hyperpigmented skin appears to fade more rapidly than does normal skin, and exposure to sunlight reduces the depigmenting effect of the drug. Following skin depigmentation after topical application of monobenzone, the histological studies indicate similar results as that seen in vitiligo, where the epidermis is intact but with the absence of identifiable melanocytes. ...INTERFERES WITH BIOSYNTHESIS OF MELANIN. IT INHIBITS ENZYME TYROSINASE & THEREBY PREVENTS CONVERSION OF TYROSINE TO DIHYDROXYPHENYLALANINE, PRECURSOR OF MELANIN.

Pharmacodynamics

Monobenzone is the monobenzyl ether of hydroquinone. Monobenzone, applied topically to the skin, is used as a depigmenting agent inhibitting melanin produced by polymerization of oxidation products of tyrosine and dihydroxyphenyl compounds. Monobenzone works by permanently removing color from normal skin located around skin with vitiligo.

Mechanism of action

Plant growth regulator with systemic properties. Penetrates into the plant tissues, and is decomposed to ethylene, which affects the growth processes. Studies have established the variety of target sites in pests and nontarget organisms at which the metabolically activated organophosphorus pesticides act. The high potency and specificity of the organophosphorus pesticides have made these cmpd useful chemical probes to further the knowledge of their mode of action and their metabolism. Many organophosphorus pesticides have been classified as phosphorylating agents. Some enzymes inhibited by organophosphorus cmpd have included acetylcholinesterase, kynurenine formamidase, neuropathy-target esterase, carboxyesterases, and other unknown esterases. Bioactive phosphorylating agents have been designed that are sufficiently stable to reach the organism, yet are reactive at the target site. The majority of organophosphorus bioactivations have been initiated by oxidation at sulfur or nitrogen connected to phosphorus, but some bioactivations involve oxidation at carbon or heteroatom centers distant from phosphorus. The phosphorus center is not the toxic site of some organophosphorus cmpd. The toxic effects of phosphinyliminodithiolanes, phosphorothionates, and ethephon are mediated through other reactive moieties. Butyrylcholinesterase (BChE) is inhibited by the plant growth regulator (2-chloroethyl)phosphonic acid (ethephon) as observed 25 years ago both in vitro and in vivo in rats and mice and more recently in subchronic studies at low doses with human subjects. The proposed mechanism is phosphorylation of the BChE active site at S198 by ethephon dianion. The present study tests this hypothesis directly using [(33)P]ethephon and recombinant BChE (rBChE) with single amino acid substitutions and further evaluates if BChE is the most sensitive esterase target in vitro and with mice in vivo. [(33)P]Ethephon labels purified rBChE but not enzymatically inactive diethylphosphoryl-rBChE (derivatized at S198 by preincubation with chlorpyrifos oxon) or several other esterases and proteins. Amino acid substitutions that greatly reduce rBChE sensitivity to ethephon are G117H and G117K in the oxyanion hole (which may interfere with hydrogen bonding between glycine-N-H and ethephon dianion) and A328F, A328W, and A328Y (perhaps by impeding access to the active site gorge). Other substitutions that do not affect sensitivity are D70N, D70K, D70G, and E197Q which are not directly involved in the catalytic triad. The effect of pH and buffer composition on inhibition supports the hypothesis that ethephon dianion is the actual phosphorylating agent without activation by divalent cations. Human plasma BChE in vitro and mouse plasma BChE in vitro and in vivo are more sensitive to ethephon than any other esterases detected by butyrylthiocholine or 1-naphthyl acetate hydrolysis in native-PAGE. All mouse liver esterases observed are less sensitive than plasma BChE to ethephon in vitro and in vivo. More than a dozen other esterases examined are 10-100-fold less sensitive than BChE to ethephon. Thus, BChE inhibition continues to be the most sensitive marker of ethephon exposure.

Mechanism of action

Strychnine is a strong convulsant. The alkaloid excites the CNS by specifically antagonizing the inhibitory neurotransmitter amino acid, glycine, at postsynaptic receptors. Inhibitory glycine receptors are abundant in the spinal cord and brain stem where they are mainly involved in regulation of motor functions. Strychnine-binding glycine receptors were also found in the cortex, as well as in the auditory and visual systems. When inhibition is blocked, ongoing neuronal excitability is increased and sensory stimuli produce exaggerated reflex effects. Glycine receptors in higher brain centers such as the substantia nigra, neostriatum, and hippocampus are commonly insensitive to strychnine, explaining why strychnine symptoms are largely spinal in origin. Strychnine can also depress nicotinic-cholinergic responses through interaction with nicotinic receptors and at high concentrations in vitro binds to other receptors as well.
