Most patients with multiple sclerosis (MS) present with the relapsing-remitting form of the disease. Pharmacologic treatment usually includes a disease-modifying drug, corticosteroids for acute exacerbations, and other drugs for managing symptoms such as fatigue, depression, and pain. Early use of disease-modifying therapy has improved clinical outcomes.

Mitoxantrone (Novantrone - Lederle), a synthetic anthracene related to the anthracyclines doxorubicin (Adriamycin) and daunorubicin (Cerubidine), has now been marketed in the USA to be used in combination with other drugs for initial treatment of acute nonlymphocytic leukemia in adults.

The FDA has approved an intravenous (IV) formulation of acetaminophen (Ofirmev – Cadence) for use in patients ≥2 years old for management of pain either as monotherapy (mild to moderate pain) or with an opioid (moderate to severe pain) and for reduction of fever.

(Ceredase - Genzyme) a modified form of the glycoprotein enzyme glucocerebrosidase prepared from human placenta, was recently approved by the US Food and Drug Administration as an 'orphan drug' for treatment of patients with the non-neurologic form of Gaucher's disease (Type 1).

Irinotecan hydrochloride (Camptosar - Pharmacia & Upjohn; formerly CPT-11) has been approved by the US Food and Drug Administration for treatment of metastatic colorectal cancer refractory to other drugs including fluorouracil (5-FU; Adrucil and others).

The alkylating agent lurbinectedin (Zepzelca – Jazz) has received accelerated approval from the FDA for treatment of metastatic small-cell lung cancer (SCLC) in adults with disease progression on or after platinum-based chemotherapy. Accelerated approval was based on the overall response rate and duration of response. About 13-15% of lung cancers are small-cell cancers. Most SCLCs occur in patients who are current or former smokers.

A variety of cancer chemotherapy drugs are used, mostly in combination, for treatment of locally advanced and metastatic esophageal, gastric and colorectal cancers. The mechanism of action, indications and adverse effects of some of these drugs are discussed in thei article.

Chelation therapy involves oral administration, intravenous infusion or intramuscular injection of drugs that increase excretion of heavy metals. The Medical Letter’s last article on this subject found no evidence that it was effective for treatment of cardiovascular disease. Since then, off-label use of chelation therapy has expanded to include treating children with autism and adults with Alzheimer’s disease, cancer and other chronic diseases.
