BETASIL PEPPERMINT 8.5MG/7.5MG LOZENGES

Indications

• Eczema
• Dermatitis
• Psoriasis
• Allergic reactions
• Insect bites

Dosage

Children: In children, the dosage is usually lower and should be determined based on the specific condition and the child's age and weight. It is important to refer to appropriate pediatric guidelines for dosing recommendations.

Adults: The dosage of Betasil depends on the condition being treated and the formulation used. It is typically applied in a thin layer to the affected area once or twice daily, depending on the severity and location of the condition. For specific dosing recommendations, refer to product-specific guidelines or consult a healthcare professional.

Mechanism of action

Betasil exerts its effects by binding to glucocorticoid receptors, leading to the modulation of gene expression. This results in the inhibition of pro-inflammatory cytokines and the induction of anti-inflammatory proteins. Additionally, it stabilizes lysosomal membranes, decreasing the release of inflammatory mediators and promoting vasoconstriction, which contributes to its anti-inflammatory effects.

Pharmacodynamics

The pharmacodynamic effects of Betasil include a reduction in the inflammatory response and modulation of the immune response. It also acts to decrease the permeability of capillaries, which reduces edema and erythema. Its efficacy in treating inflammatory skin conditions can vary based on the vehicle used in the formulation, as the absorption and penetration may differ.

Pharmacokinetics

Betasil is absorbed through the skin, with the extent of absorption depending on the formulation, the area of application, and the condition of the skin. Once absorbed, it is metabolized in the liver, and its metabolites are excreted in the urine. The onset of action can vary, with effects typically observed within hours of application. Systemic absorption is generally low, but occlusive dressings can enhance systemic exposure.

Pregnancy

Consult with a healthcare provider before use as safety during pregnancy has not been established.

Breast-feeding

Consult with a healthcare provider before use as it is unknown if the drug is excreted in human milk.

Storage

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

Indications

• Irritable bowel syndrome
• Dyspepsia
• Nausea
• Headaches
• Respiratory congestion

Dosage

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

Adults: Refer to the relevant product-specific information for dosing recommendations, as peppermint formulations can vary widely.

Mechanism of action

The primary active component, menthol, works by activating the TRPM8 (transient receptor potential cation channel subfamily M member 8) ion channel, which is involved in the sensation of cold and cooling. This action can lead to a localized anesthetic effect, reducing pain and discomfort. Additionally, menthol can cause relaxation of smooth muscle in the gastrointestinal tract, aiding in the relief of digestive symptoms.

Pharmacodynamics

Peppermint exhibits antispasmodic effects, particularly in the gastrointestinal tract, by relaxing the smooth muscles. It also has a mild analgesic effect due to its cooling sensation, which can provide symptomatic relief in various conditions. Furthermore, peppermint oil may have antimicrobial properties, contributing to its use in treating certain infections.

Pharmacokinetics

Menthol is rapidly absorbed after oral administration and is metabolized in the liver. The peak plasma concentration typically occurs within a few hours. The elimination half-life of menthol is approximately 1.5 to 2 hours, and it is primarily excreted in the urine as metabolites. The pharmacokinetics of peppermint oil can vary based on the formulation and route of administration.

Interactions

• peppermint oil + lomitapide: Unknown (increases exposure)

Pregnancy

Peppermint is generally considered safe for use in pregnancy when used in culinary amounts. However, high doses should be avoided due to potential uterine stimulation.

Breast-feeding

Peppermint is considered safe during breastfeeding when used in culinary amounts. Caution is advised with high doses as effects on the infant are not well studied.

Storage

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