Betaval Lotion 60ml Overview

Generic Information

• Generic Name: Betamethasone valerate
• Brand Name: Betaval Lotion
• Formulation: Lotion (Topical)
• Volume: 60 mL

Pharmaceutical Class

• Class: Corticosteroids (Topical)
• Type: Glucocorticoid, Anti-inflammatory corticosteroid

Indications for Use

Betaval Lotion (betamethasone valerate) is used for the treatment of inflammatory skin conditions, such as:

• Eczema (Atopic dermatitis)
• Psoriasis
• Contact dermatitis (allergic reactions)
• Seborrheic dermatitis
• Other inflammatory skin conditions that are responsive to corticosteroids.

Common Side Effects

• Skin irritation: Burning, stinging, or itching at the site of application.
• Dryness or peeling of the skin.
• Skin thinning (with prolonged use).
• Stretch marks (striae).
• Folliculitis: Inflammation of hair follicles.
• Hypopigmentation: Lightening of the skin at the site of application.

Serious Side Effects (Less Common)

• Adrenal suppression: Particularly with prolonged or extensive use, this can affect the adrenal glands, reducing hormone production.
• Cushing’s syndrome: Symptoms may include weight gain, “moon face,” and thinning skin.
• Delayed wound healing: Corticosteroids can impair the skin’s ability to heal wounds.
• Skin infections: Risk of infections, particularly if the skin is broken or damaged.
• Systemic side effects: Rare but possible, especially with prolonged use, including effects on metabolism and immune function.

Dosage and Usage Instructions

• Typical Dosage: Apply a thin layer of Betaval Lotion to the affected area 1-2 times per day.
• Duration of Use: The treatment should generally not extend beyond 2 weeks unless directed by a healthcare provider, to avoid complications like skin thinning and adrenal suppression.
• Application: Clean and dry the affected area before application. Avoid applying to broken or infected skin unless directed by a doctor. Do not cover with airtight dressings unless advised by a healthcare provider.
• Discontinuation: If no improvement is observed after a few weeks or if side effects occur, consult a healthcare provider for advice.

Drug Interactions

• With Food: There are no significant interactions with food for Betaval Lotion.
• With Other Medications:
  • CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): These can increase the systemic absorption of corticosteroids, enhancing their effects and side effects.
  • Other corticosteroids (oral or topical): The concurrent use of other corticosteroids should be avoided due to the increased risk of systemic corticosteroid effects, such as adrenal suppression, skin thinning, and other adverse effects.
  • Immunosuppressive drugs (e.g., cyclosporine): Using immunosuppressive drugs with Betaval Lotion may increase the risk of infections or delay wound healing.
• Other Interactions:
  • Topical alcohol-based products: These may increase skin irritation when used alongside Betaval Lotion.
  • Infection control: Caution is advised when using Betaval Lotion on areas with active infections.

Regulatory Approval and Manufacturer

• Regulatory Approval: Betaval Lotion is approved by health authorities like the FDA and EMA for the treatment of inflammatory skin conditions.
• Manufacturer: Betaval Lotion is generally manufactured by GlaxoSmithKline (GSK) or other regional pharmaceutical companies depending on the market.

Pharmacist-Related Data

Drug Name and Chemical Details

• Drug Name: Betamethasone valerate
• Chemical Formula: C22H29FO5
• Molecular Weight: 392.47 g/mol
• CAS Number: 2152-44-5
• Chemical Structure: Betamethasone valerate is a synthetic corticosteroid, which belongs to the glucocorticoid class and possesses anti-inflammatory and immunosuppressive properties.

Pharmacodynamics

Mechanism of Action

Betamethasone valerate is a glucocorticoid that acts by binding to specific receptors within target cells, forming a complex that translocates to the cell nucleus. This interaction alters gene expression, leading to the suppression of pro-inflammatory mediators such as cytokines and prostaglandins, thereby reducing inflammation and immune responses.

Therapeutic Effects

• Anti-inflammatory: Reduces inflammation in the skin, relieving symptoms such as redness, swelling, and discomfort.
• Immunosuppressive: Suppresses immune system responses, particularly in allergic or autoimmune skin conditions.
• Antipruritic: Alleviates itching associated with inflammatory skin disorders.

Pharmacokinetics

Absorption

• Betamethasone valerate is absorbed through the skin upon topical application. The extent of absorption is influenced by factors such as the condition of the skin (e.g., broken or inflamed skin increases absorption). Systemic absorption is usually minimal, but it can be enhanced with prolonged or excessive use.

Distribution

• After absorption, the drug is distributed throughout the body, although in low concentrations due to its topical use. Betamethasone is known to concentrate in fatty tissues and has a relatively low systemic bioavailability when used as directed.

Metabolism

• Betamethasone valerate is primarily metabolized by the liver to inactive metabolites that do not contribute to the drug’s therapeutic effects.

Excretion

• The inactive metabolites are excreted in the urine. Only a small amount is excreted through the feces.

Half-Life

• The half-life of betamethasone valerate is typically 5–10 hours in plasma. However, the half-life in the skin tissue may be prolonged, especially with extended use or high doses.

Drug Interactions

With Food

• No significant food interactions are known for Betaval Lotion.

With Other Medications

• CYP3A4 inhibitors (e.g., ketoconazole, ritonavir): These medications can increase the systemic absorption of Betaval Lotion, leading to a higher risk of systemic corticosteroid effects like adrenal suppression and other adverse effects.
• Other corticosteroids (oral or topical): Concurrent use of other corticosteroids should be avoided to prevent excessive systemic absorption and associated side effects.
• Immunosuppressants (e.g., cyclosporine, methotrexate): The combination of Betaval Lotion with immunosuppressive agents can heighten the risk of infections and delay the skin’s healing process.

Other Interactions

• Alcohol-based topical treatments: These can cause skin irritation when used with Betaval Lotion and should be avoided.
• Infection: Betaval Lotion should be used cautiously on skin with active infections, as corticosteroids may mask infection symptoms and increase susceptibility to skin infections.

Clinical Considerations

Pregnancy Category

• Category C: Betaval Lotion is classified as Category C during pregnancy, meaning that it should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus. Prolonged or extensive use should be avoided during pregnancy.

Lactation

• Betamethasone can pass into breast milk, but in small amounts. Although the risk is low with topical use, it is still advised to use Betaval Lotion with caution while breastfeeding, particularly with long-term use or when applied to large areas of skin.

Pediatric Use

• Pediatric patients are more vulnerable to the systemic effects of corticosteroids. Prolonged use of Betaval Lotion in children can result in growth suppression and skin thinning. The medication should only be used on children for short periods, and it should be applied cautiously.

Geriatric Use

• Older adults may be more prone to side effects like skin thinning, delayed wound healing, and adrenal suppression. Therefore, Betaval Lotion should be used with caution in geriatric patients, and long-term use should be avoided.

Other Considerations

• Skin infections: Betaval Lotion should be used cautiously on areas of the skin with active infections, as corticosteroids can mask the signs of infection and hinder healing.
• Sensitive skin areas: Betaval Lotion should not be used extensively on sensitive skin areas (like the face, groin, or underarms) to prevent side effects such as skin thinning and other local complications.
• Occlusion: Avoid using occlusive dressings unless specifically instructed by a healthcare provider, as this can increase absorption and the risk of side effects.
