What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Description

Valchlor (mechlorethamine) is a topical antineoplastic gel indicated for the treatment of stage IA and IB mycosis fungoides-type cutaneous T-cell lymphoma (CTCL) in patients who have received prior skin-directed therapy. Mechlorethamine is a nitrogen mustard alkylating agent that works by forming cross-links in DNA, ultimately disrupting replication and leading to apoptosis of malignant T-cells in the skin. Valchlor offers a non-invasive treatment option that targets localized lesions with minimal systemic absorption.

Directions

Valchlor is applied topically once daily to affected areas of the skin. The 0.016% gel should be applied as a thin film to completely dry skin at least 30 minutes after bathing or showering. Hands should be washed immediately after application unless treating the hands themselves, and patients should allow the gel to dry completely before covering the area with clothing. Occlusive dressings should not be used unless directed by a healthcare provider. Avoid application to mucous membranes or broken skin. Treatment should be continued as prescribed, with regular monitoring by a healthcare professional for skin reactions or disease progression.

Ingredients

Each gram of Valchlor contains:

Mechlorethamine hydrochloride 0.016% (equivalent to 0.014% mechlorethamine free base)

Inactive ingredients include:

Diethylene glycol monoethyl ether, propylene glycol, hydroxypropylcellulose, and purified water

Valchlor is supplied in a multi-use aluminum tube with a plastic screw cap and should be stored in the refrigerator (2°C to 8°C). Do not freeze.

Contraindications

Valchlor is contraindicated in patients with:

Hypersensitivity to mechlorethamine or any component of the formulation

Presence of open wounds, ulcerated skin, or active dermatoses where absorption may be increased

Concomitant use with topical products containing silver (e.g., silver sulfadiazine), which can inactivate mechlorethamine

Cautions

Valchlor is cytotoxic and should be handled with care. Use protective gloves when applying to others. Contact with mucous membranes, eyes, or non-affected skin may cause severe irritation or injury. Patients should avoid sunlight or UV exposure on treated areas due to potential photosensitivity. Secondary malignancies, including skin cancer, have been reported with long-term use of topical nitrogen mustards. Women who are pregnant or breastfeeding should not use Valchlor due to risk of fetal harm. Effective contraception is recommended for both male and female patients during and after treatment.

Common and potential side effects include:

Dermatitis (irritant or allergic)

Pruritus or burning sensation at the application site

Skin ulceration or blisters

Hyperpigmentation or hypopigmentation
