Ganciclovir for the treatment and suppression of serious infections caused by cytomegalovirus.
Ganciclovir is a congener of acyclovir with in vitro activity against cytomegalovirus. Ninety-seven patients with the acquired immune deficiency syndrome (AIDS) and a serious cytomegalovirus infection received ganciclovir, 3.0 to 15 mg/kg per day. Viremia cleared during drug therapy in 88 percent of patients. Viral shedding from urine and throat ceased or became inapparent during treatment in 78 percent and 68 percent of patients, respectively. Among patients with cytomegalovirus retinitis, 87 percent of evaluable patients had improvement in (30 of 60) or stabilization (22 of 60) of their disease. However, when the drug was discontinued, progression or recurrence of disease always occurred. Long-term suppressive therapy with ganciclovir, 5.0 mg/kg five to seven times weekly, prevented the recurrence of cytomegalovirus disease (p less than 0.001). The drug was eliminated by renal excretion, and in patients without renal impairment (creatinine clearance rates of more than 60 ml/minute/1.73 m2), ganciclovir has a mean half-life of 4.2 hours. Significant neutropenia and leukopenia occurred in 55 percent and 32 percent of patients, respectively.
