Acyclovir update

Clinical use of acyclovir.

Acyclovir transport into human erythrocytes.

The mechanism of transport of the antiviral agent acyclovir (ACV) into human erythrocytes has been investigated. Initial velocities of ACV influx were determined with an "inhibitor-stop" assay that used papaverine to inhibit ACV influx rapidly and completely. ACV influx was nonconcentrative and appeared to be rate-saturable with a Km of 260 +/- 20 microM (n = 8). However, two lines of evidence ...

Polymorphs and hydrates of acyclovir.

Acyclovir (ACV) has been commonly used as an antiviral for decades. Although the crystal structure of the commercial form, a 3:2 ACV/water solvate, has been known since 1980s, investigation into the structure of anhydrous ACV has been limited. Here, we report the characterization of four anhydrous forms of ACV and a new hydrate in addition to the known hydrate. Two of the anhydrous forms appear...

Acyclovir Therapy for Herpesvirus Infections

boast authors who are experts in their fields, stand alone as comprehensive critiques of the current technology or as organized, well-integrated sections of the complete retrovirus body of literature. Clinicians and basic researchers will appreciate the well-balanced coverage of disease and molecular processes, the clear prose, the concise summaries, and, finally, the comprehensive citation of ...

Neonatal Sepsis: An Update

Sepsis is the most common cause of neonatal mortality. As per National Neonatal-Perinatal Database (NNPD), 2002-2003, the incidence of neonatal sepsis in India was 30 per 1000 live births. Signs and symptoms of sepsis are nonspecific; therefore empirical antimicrobial therapy is promptly initiated after obtaining appropriate cultures. The early manifestations of neonatal sepsis are vague and il...
