The CRP level is not influenced by various hematologic factors or age and is more sensitive than the ESR for the detection of TA. The combination of ESR and CRP levels gives the best specificity 97%. Clinical studies of acyclovir did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. Other reported clinical experience has identified differences in the severity of CNS adverse events between elderly and younger patients see ADVERSE REACTIONS: Observed During Clinical Practice. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased renal function, and of concomitant disease or other drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. does levothroid pills expire

Famciclovir is a prodrug of penciclovir, which has demonstrated inhibitory activity against herpes simplex virus types 1 HSV-1 and 2 HSV-2 and varicella zoster virus VZV. In cells infected with HSV-1, HSV-2 or VZV, the viral thymidine kinase phosphorylates penciclovir to a monophosphate form that, in turn, is converted by cellular kinases to the active form penciclovir triphosphate. Biochemical studies demonstrate that penciclovir triphosphate inhibits HSV-2 DNA polymerase competitively with deoxyguanosine triphosphate. Consequently, herpes viral DNA synthesis and, therefore, replication are selectively inhibited. Penciclovir triphosphate has an intracellular half-life of 10 hours in HSV-1-, 20 hours in HSV-2-and 7 hours in VZV-infected cells grown in culture. However, the clinical significance of the intracellular half-life is unknown. Table 3 lists selected laboratory abnormalities in genital herpes suppression trials.
