I. THERAPEUTIC CLASS

per 0.65mL dose supplied as single dose vials .
II. CLINICAL PHARMACOLOGY
Herpes Zoster
Herpes zoster (HZ), commonly known as shingles or simply “ zoster,” is a manifestation of the
reactivation of VZV, which, as a primary infection, produces chickenpox (varicella). Following
initial infection, the virus remains latent in the dorsal root or cranial sensory ganglia until it
reactivates, producing zoster. Zoster is usually characterized by a unilateral, painful, ves icular
cutaneous eruption with a dermatomal distribution.
Although the blistering rash is the most distinctive feature of zoster, the most frequently
debilitating symptom is pain, which may occur during the prodrome, the acute eruptive phase,
and the post herpetic phase of the infection. During the acute eruptive phase, local pain has
been reported to occur in up to 90% of immunocompetent individuals.
Anyone who has been infected with VZV, including those without a clinical history of varicella, is
at ris k for developing zoster, which is considered to be due to waning immunity to VZV. Nearly
all adults (~98%) in the U.S. are susceptible to zoster, where an estimated 1 million cases occur
annually. This number is expected to rise as the mean age of the pop ulation increases. The
