• 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.

Mechanism of action

Isoflavones exert their effects primarily by selectively binding to estrogen receptors, specifically ERβ, with a significantly higher affinity compared to ERα. This selective binding allows isoflavones to mimic estrogen in certain tissues, while also exhibiting antiestrogenic actions by blocking the binding of endogenous estrogens to their receptors. They have been shown to inhibit the proliferation of cancer cells, induce apoptosis, and modulate various metabolic pathways, including eicosanoid metabolism. Isoflavones may also improve endothelial function and support cardiovascular health by enhancing the number of circulating endothelial progenitor cells.

Pharmacodynamics

Isoflavones have been associated with several beneficial effects, particularly in postmenopausal women. Clinical studies indicate that they can lower LDL cholesterol levels, reduce blood pressure, and attenuate bone loss. They are also linked to modulation of biomarkers related to cancer development, especially in prostate cancer patients, where they may decrease prostate-specific antigen (PSA) levels and influence testosterone and androgen receptor activity. However, the evidence surrounding their impact on menopausal symptoms and cancer remains inconclusive.

Pharmacokinetics

The absorption and bioavailability of isoflavones vary depending on factors such as dietary intake and individual metabolism. Isoflavones are generally well absorbed in the gut, with peak plasma concentrations occurring within a few hours after ingestion. They undergo extensive metabolism in the liver, resulting in various metabolites that may exhibit distinct biological activities. The elimination half-life of isoflavones can vary, with some metabolites being excreted in urine. Continuous consumption may lead to accumulation and prolonged effects.

Mechanism of action

The active compounds in Paeoniae may exert their effects through multiple mechanisms, including modulation of inflammatory mediators and antioxidant activity. Some studies suggest that it may inhibit the production of pro-inflammatory cytokines and promote the expression of anti-inflammatory cytokines, thereby reducing inflammation. Additionally, certain components may enhance blood circulation and exert a mild sedative effect.

Pharmacodynamics

Paeoniae exhibits a range of pharmacological activities, including anti-inflammatory, analgesic, and calming effects. The anti-inflammatory properties are thought to be mediated by the inhibition of cyclooxygenase and lipoxygenase pathways, which are critical in the synthesis of inflammatory mediators. The calming effects may be due to its ability to modulate neurotransmitter levels, including GABA.

Pharmacokinetics

The pharmacokinetic profile of Paeoniae has not been extensively studied. However, it is known that the absorption, distribution, metabolism, and excretion of its active compounds can be influenced by the preparation method, dosage form, and individual patient factors. The bioavailability of the compounds may vary, affecting their therapeutic efficacy.

Pregnancy

Insufficient data are available to establish the safety of paeoniae during pregnancy. It is recommended to consult healthcare professionals before use.

Breast-feeding

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

Isoflavones are selective estrogen receptor modulators that exert estrogenic-like effects under certain experimental conditions, as they are structurally similar to mammalian 17β-estradiol. They may bind to both α and β isoforms of estrogen receptor (ER), but with binding affinities to ERβ approximately 20 times higher than that to ERα. The role of isoflavones on estrogen-dependent cancer has been studied, since they may mediate antiestrogenic actions by blocking the binding of endogenous estrogens and their receptor signalling. In cell culture, [DB01645] inhibited the proliferation of MDA-MB-231 human breast cancer cells, probably by arresting the cell cycle progression at the G2–M transition. In addition, genistein was shown to induce apoptosis, modify eicosanoid metabolism, and inhibit angiogenesis. There is an evidence that soy isoflavones may act on androgen receptors to inhibit tyrosine kinase activity, thereby blocking the growth and proliferation of cancer cells. Isoflavones may not significantly contribute to the hypolipidemic effects of soy protein, but may exert coronary benefits by improving endothelial function; in clinical trials of postmenopausal women, isoflavones improved flow-mediated dilation in women with impaired endothelial function. Some observational data suggests that isoflavones improve endothelial function by increasing the number of circulating endothelial progenitor cells, which replace damaged endothelial cells. Isoflavone may modulate the key transcription factors involved in the regulation of lipid metabolism by acting on the peroxisome proliferator-activated receptors (PPAR) alpha and gamma, which are receptors that regulate the transcription of genes involved in lipid and glucose homeostasis and lipid metabolism. Multiple biological actions of isoflavones, such as favorable effect on the blood lipid profile and inhibition of LDL cholesterol oxidation, may lead to cardio protective effects. [DB01645] has been shown to have antioxidant properties on hydrogen peroxide production _in vitro_ and blocks the formation of oxygen free radicals. Studies also suggest that at micromolar concentrations, genistein increases glucose-stimulated insulin secretion in cell lines and mouse pancreatic islets via a cAMP-dependent protein kinase mechanism. Based on the findings of experimental studies, genistein may exert a positive effect on bone formation by decreasing osteoclastic resorption factor, such as collagen C-telopeptide, and increasing osteoblastic formation markers, such as bone-alkaline phosphatase. _In vitro_, it antagonized the catabolic effects of parathyroid hormone (PTH) in osteoblasts by reversing the PTH-induced increase in soluble receptor activator of nuclear factor-xB ligand and decrease in osteoprotegerin expression.

Pharmacodynamics

Isolated soy protein with isoflavones was shown to decrease LDL cholesterol levels in randomized trials assessed by the American Heart Association. In a study of postmenopausal women, daily dietary intake of 101 mg of aglycone isoflavones (indicating [DB01645] and [DB13182]) was associated with lowered LDL cholesterol and apolipoprotein B levels by 8% and reduced systolic and diastolic blood pressure by 6.8% in hypertensive women. In a meta-analysis of randomized controlled trials of menopausal women, soy isoflavones attenuated bone loss of the spine and decreased the levels of deoxypyridinoline, a bone resorption marker, while increasing serum bone-specific alkaline phosphatase, a bone formation marker. The findings from studies investigating the effects of soy consumption on menopausal symptoms, breast cancer, and prostate cancer remain somewhat controversial and inconclusive. Consumption of soy isoflavones may decrease the markers of cancer development and progression in prostate cells, including prostate-specific antigen (PSA), testosterone, and androgen receptor in patients with prostate cancer but not in normal subjects. Although epidemiologic data in Asian women demonstrate that high soy food intake is associated with protection against breast cancer, soy foods have little effect on intermediary markers of breast cancer risk and postmenopausal soy intake may not reduce the risk of developing breast cancer. However, preliminary studies show that soy food intake reduces tumor recurrence in breast cancer patients. Soy isoflavones reported to interfere with thyroid peroxidase, which are involved in the production of thyroid hormones.
