1. Qual a diferença do Oseltamivir em relação aos antivirais usados para tratamento de Herpes e HIV? Qual o mecanismo de ação de cada um deles?
O Oseltamivir, classificado como inibidor da liberação da desmontagem viral, é um antiviral que inibe de forma seletiva a enzima neuroaminidase específica do vírus influenza, que é essencial para a entrada e liberação desse vírus nas células humanas. Desta forma, o oseltamivir, administrado por via oral, inibe a replicação dos vírus influenza

3. Vegetative chronic genital herpes with satisfactory response to imiquimod
Abstract Vegetative chronic genital herpes is an atypical presentation of herpes simplex 2 that it is usually seen in patients coinfected with human immunodeficiency virus. Clinically, it is characterized by extensive ulcers that evolve to chronification and hypertrophic pseudotumor forms. Antiviral drugs are recommended for the treatment, and acyclovir is t

4. Determination of Elemental Impurities in Acyclovir Ointment and Raw Materials Using Microwave Acid Digestion (MW-AD) and ICP-MS
Inorganic elements present in pharmaceutical products were determined by inductively coupled plasma-mass spectrometer (ICP-MS), employing microwave acid digestion as a sample preparation method. The most abundant isotopes, 75As+, 65Cu+, 52Cr+, 58Ni+, 208Pb+, and 51V+, were determined in acyclovir ointment and its constituents. Elemental impurities in the pha

5. Improvement of physicochemical parameters of acyclovir using cocrystallization approach
ABSTRACT Acyclovir is an antiviral drug having potent activity against the virus of herpes family and varicella zoster. Unfortunately, drug suffers very poor oral bioavailability (15-30%). The main objective of present study was to develop acyclovir cocrystals with improved solubility which may result in improvement of bioavailability. Hansen solubility appr

6. Herpes zoster after autologous hematopoietic stem cell transplantation
ABSTRACT Background: The autologous hematopoietic stem cell transplantation procedure involves immunosuppression of the patient. Thus, the patient has an elevated risk for several diseases, such as infections with the varicella-zoster virus. Prevention protocols have been proposed based on the use of acyclovir from the first day of conditioning, and maintai

8. In vitro evaluation of cutaneous penetration of acyclovir from semisolid commercial formulations and relation with its effective antiviral concentration
ABSTRACT The evaluation of drug permeation/penetration of semisolid formulations into animal skin can be useful to supplement the pharmaceutical equivalence. This paper describes the in vitro assessment of acyclovir (ACV) into porcine skin from commercial formulations with etermination of drug concentration in different layers of cutaneous tissue to correlat

9. Cutaneous neonatal herpes simplex virus infection type 2: a case report
Abstract Neonatal herpes is a serious condition. Newborns can be contaminated in utero via transplacental hematogenic transmission, upon delivery (the most frequent route), or during the postnatal period (indirect transmission). Optimal management requires prompt and accurate recognition, particularly in newborns, in order to prevent complications. Acyclovir

11. Herpes simplex virus: isolation, cytopathological characterization and antiviral sensitivity
BACKGROUND:Herpes simplex virus (HSV) infection is an endemic disease and it is estimated that 6095% of the adult population are infected with symptoms that are usually self-limiting, though they can be serious, extensive and prolonged in immunocompromised individuals, highlighted by the emergence of drug-resistant strains. The study of the wild-type HSV str

12. Chloroquine diphosphate: a risk factor for herpes zoster in patients with dermatomyositis/polymyositis
OBJECTIVES: Herpes zoster has been widely described in the context of different systemic autoimmune diseases but not dermatomyositis/polymyositis. Therefore, we analyzed the prevalence, risk factors and herpes zoster outcomes in this population. METHOD: A retrospective cohort study of herpes zoster infections in dermatomyositis/polymyositis patients was p
