The FDA has recently approved 2 new drugs for treatment of chronic hepatitis C virus (HCV) infection. Simeprevir (Olysio – Janssen) is the third oral protease inhibitor to be approved for use in combination with peginterferon and ribavirin for treatment of chronic HCV genotype 1 infection in adults with compensated liver disease. Telaprevir (Incivek) and boceprevir (Victrelis) were approved in 2011 for the same indication. Sofosbuvir (Sovaldi – Gilead), a nucleotide analog polymerase inhibitor that has been approved for use with and without interferon for treatment of multiple HCV...

The FDA has approved an oral solution of the nonselective beta-adrenergic blocker propranolol (Hemangeol – Pierre Fabre) for treatment of proliferating infantile hemangiomas.

Many drugs can cause psychiatric symptoms, but a causal connection is often difficult to establish. Psychiatric symptoms that emerge during drug treatment could also be due to the underlying illness, previously unrecognized psychopathology, or psychosocial factors. The withdrawal of some drugs can cause symptoms such as anxiety, psychosis, delirium, agitation or depression.

Bexxar, a combination of the monoclonal antibody tositumomab and radiolabeled Iodine-131 tositumomab (Corixa Corp/GlaxoSmithKline) has been approved by the FDA for a single treatment of relapsed follicular non-Hodgkin's lymphoma (NHL) in patients who are refractory to rituximab (Rituxan - Medical Letter 1998; 40:65). It is the second radioimmunoconjugate to be approved for refractory NHL; yttrium-90 linked to ibritumomab tiuxetan (Zevalin) was approved in 2002. Tositumomab, like ibritumomab, is a monoclonal antibody of mouse origin that binds to the CD20 antigen present on the surface of >90%...

The FDA has approved the nucleoside analog telbivudine (Tyzeka - Novartis/Idenix) for treatment of patients ≥16 years old with active chronic hepatitis B virus (HBV) infection. It is the fourth oral drug marketed for this indication in the US.

The FDA has approved romidepsin (Istodax – Celgene), an IV histone deacetylase (HDAC) inhibitor, for treatment of cutaneous T-cell lymphoma (CTCL) in patients who have received at least one prior systemic therapy. The most common types of CTCL are mycosis fungoides, a low-grade lymphoma usually confined to the skin, and Sézary syndrome, a more aggressive disease with malignant lymphocytes in the blood. Both can progress to fatal systemic involvement. Romidepsin is the second HDAC inhibitor approved for this indication; vorinostat (Zolinza), an oral HDAC inhibitor, was approved...

Vorinostat (Zolinza - Merck), an oral histone deacetylase (HDAC) inhibitor, has received accelerated approval from the FDA for treatment of skin manifestations of cutaneous T-cell lymphoma (CTCL) that is persistent, progressive or recurrent after two systemic therapies. The most common types of CTCL are mycosis fungoides and SΘzary syndrome, the leukemic form of mycosis fungoides.

Telaprevir (Incivek – Vertex) and boceprevir (Victrelis – Merck) have been approved by the FDA for oral use in combination with peginterferon and ribavirin for treatment of chronic hepatitis C virus (HCV) genotype 1 infection in adults with compensated liver disease. Both telaprevir and boceprevir were developed specifically to inhibit the NS3/4A proteases that cleave HCV encoded polyproteins of the genotype 1 virus.

Many commonly used drugs can interfere with sexual function in both men and women, causing loss of libido, interfering with erection or ejaculation in men, and delaying or preventing orgasm in women. Drug-related effects on sexual function may be difficult to distinguish from the effects of depression or disease, but most are reversible when drug use is stopped and sometimes when dosage is decreased. Since many patients are reluctant to talk about sexual difficulties, physicians may wish to ask about the possibility of drug-induced sexual dysfunction, particularly when they have...

The FDA has approved daclatasvir (Daklinza – BMS), an oral direct-acting antiviral drug, for use with sofosbuvir (Sovaldi) for treatment of chronic hepatitis C virus (HCV) genotype 3 infection. Daclatasvir is the first drug approved for this indication that does not require the addition of interferon or ribavirin. It is approved in Japan and Europe in combination with other drugs for treatment of HCV genotypes 1-4.
