Mitoxantrone Intravenous, Injection and Phenytoin Sodium

• Generic Name: mitoxantrone
• Dosage Forms: n.a.
• Other Brand Names: Novantrone

Mitoxantrone injection is used alone or together with other medicines to treat advanced prostate cancer and acute nonlymphocytic leukemia (ANLL). It belongs to the group of medicines known as antineoplastics or cancer medicines. Mitoxantrone is also used to treat some forms of multiple sclerosis (MS). Mitoxantrone will not cure MS, but it may extend the time between relapses.

Mitoxantrone interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by mitoxantrone, other unwanted effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, like hair loss, may not be serious but may cause concern. Some unwanted effects may not occur for months or years after the medicine is used.

Before you begin treatment with mitoxantrone, you and your doctor should talk about the good mitoxantrone will do as well as the risks of using it.

Mitoxantrone is to be administered only by or under the immediate supervision of your doctor.

• Generic Name: phenytoin

Management of generalized tonic-clonic (grand mal) seizures.

Management of partial seizures with complex symptomatology (psychomotor and temporal lobe seizures).

Not recommended for treatment of pure absence (petit mal) seizures since the drug may increase frequency of these seizures, but may be used in conjunction with other anticonvulsants when mixed seizure types are present.

Prevention and treatment of seizures occurring during and following neurosurgery.

Used IV for treatment of status epilepticus; however, use may be limited by its slow onset of action and need for slow administration.

Benzodiazepines (e.g., diazepam, lorazepam, midazolam) are considered drugs of choice for initial treatment of status epilepticus; IV phenytoin (or fosphenytoin) may be used as a second-line agent if seizures continue.

Concurrent administration with an IV benzodiazepine or short-acting barbiturate will usually be necessary for rapid control of seizures.

Fosphenytoin appears to be better tolerated than phenytoin, and some experts state that fosphenytoin is preferred when both drugs are available.

Has been used IV for treatment of cardiac arrhythmias, particularly ventricular arrhythmias, in patients who do not respond to conventional antiarrhythmic agents or cardioversion. However, current use as an antiarrhythmic agent is limited by the drug's narrow therapeutic window, multiple drug interactions, and adverse effect profile.

Has been used IV for treatment of arrhythmias caused by cardiac glycoside intoxication, especially in the presence of AV block, because the drug improves conduction through the AV node.
