Multiple myeloma

Active Ingredient: Melphalan

Indication for Melphalan

Population group: only adults (18 years old or older)

Melphalan, at conventional intravenous dosage, is indicated in the treatment of multiple myeloma.

For this indication, competent medicine agencies globally authorize below treatments:

0.04 mg/kg once a day for 4 days every six weeks

Route of admnistration

Oral

Defined daily dose

0.04 - 0.04 mg per m² of body surface area (BSA)

Dosage regimen

From 0.04 To 0.04 mg per m² of body surface area (BSA) once every day for 4 day(s)

Detailed description

Numerous regimes have been used and the scientific literature should be consulted for details. The administration of melphalan and prednisone is more effective than melphalan alone. The combination is usually given on an intermittent basis, although the superiority of this technique over continuous therapy is not established. A typical oral dosage schedule is 0.15 mg/kg bodyweight/day in divided doses for 4 days repeated at intervals of six weeks. Prolonging treatment beyond one year in responders does not appear to improve results.

16-200 mg/m² body surface area once every 4 weeks

Route of admnistration

Intravenous

Defined daily dose

16 - 200 mg per m² of body surface area (BSA)

Dosage regimen

From 16 To 200 mg per m² of body surface area (BSA) once every 28 day(s)

Detailed description

Conventional dose

Melphalan is administered on an intermittent basis alone, or in combination with other cytotoxic drugs. Administration of prednisone has also been included in a number of regimens.

When used as a single agent, a typical intravenous melphalan dosage schedule is 0.4 mg/kg body weight (16 mg/m² body surface area) repeated at appropriate intervals (e.g. once every 4 weeks), provided there has been recovery of the peripheral blood count during this period.

High dose

High dose regimens generally employ single intravenous doses of between 100 and 200 mg/m² body surface area (approximately 2.5 to 5.0 mg/kg body weight), but haematopoietic stem cell rescue becomes essential following doses in excess of 140 mg/m² body surface area.

0.4-5 mg/kg once every 4 weeks

Route of admnistration

Intravenous

Defined daily dose

0.4 - 5 mg per kg of body weight

Dosage regimen

From 0.4 To 5 mg per kg of body weight once every 28 day(s)

Active ingredient

Melphalan

Melphalan is a bifunctional alkylating agent. Formation of carbonium intermediates from each of the two bis-2-chloroethyl groups enables alkylation through covalent binding with the 7-nitrogen of guanine on DNA, cross-linking the two DNA strands and thereby preventing cell replication.
