BACKGROUND There are 3 new topical treatments for herpes labialis that have either been approved by the US Food and Drug Administration (penciclovir cream [Denavir] and n-docosanol cream [Abreva]) or recently undergone extensive clinical evaluation (acyclovir cream). The relative efficacy of these products is unknown. OBJECTIVE To compare the efficacy of penciclovir cream, acyclovir cream, n-...

Acyclovir is effective in the prevention and treatment of herpes simplex virus (HSV) and varicella-zoster virus (VZV) infections. The aim of this study was to characterize the population pharmacokinetics of acyclovir observed following treatment with intravenous acyclovir and oral valacyclovir (valaciclovir) in young people with malignancy. Plasma acyclovir concentration-time data were collecte...

Ganciclovir is a nucleoside guanosine analogue that exhibits therapeutic activity against human cytomegalovirus infection, and is primarily excreted via glomerular filtration and active tubular secretion. The adverse effects induced by ganciclovir therapy are generally of a hematological nature and include thrombocytopenia and leukopenia. Low marrow cellularity and elevated serum creatinine hav...

BACKGROUND Wide distribution and low half-life of acyclovir has led to a high dose consumption of the drug. Recent studies have shown that encapsulation of acyclovir in nano-carriers can increase effectiveness and decrease its side effects. We investigated the inhibitory effect of acyclovir loaded nano-niosomes against herpes simplex virus type-1 (HSV-1) in cell culture. METHODS In-vitro cyto...

Sixty patients with simple dendritic corneal ulceration were randomly assigned to double blind treatment with either acyclovir tablets (400 mg) or acyclovir ophthalmic ointment administered five times daily. There was no significant difference in the proportions of patients healed in either treatment group (88.9% on oral acyclovir and 96.6% on acyclovir ointment). The median healing time was fi...

Cytomegalovirus (CMV) infection complicates the post-operative course of patients receiving solid organ transplants. While ganciclovir has significantly reduced the direct effects of CMV infection, some patients cannot tolerate the optimal therapeutic exposure required for CMV prevention and treatment. Few reports directly address the incidence, consequences, and risk factors for hematologic to...

The resistance of cytomegalovirus (CMV) to ganciclovir is a factor in therapeutic failure and disease progression. The clinical significance of such resistance in solid-organ transplantation has not been completely established. Six patients who developed persistent infection due to ganciclovir-resistant CMV were treated with a combination of ganciclovir (50% of the therapeutic dose) and a daily...

Sixteen patients with the Acquired Immunodeficiency Syndrome (AIDS) and cytomegalovirus retinitis were treated with ganciclovir alone (9 patients) or ganciclovir and zidovudine (6 patients). The duration of effective treatment, that is the number of weeks during which there was no deterioration in visual symptoms or retinal appearance, was comparable in both groups. However, six of the seven pa...

Mục tiêu: Nhận xét kết quả điều trị người bệnh Cytomegalovirus bằng thuốc kháng vi rút ganciclovir tại Bệnh viện nhiệt đới trung ương. Đối tượng và phương pháp nghiên cứu: Nghiên cứu mô tả trên 58 (NB) mắc do CMV được Nhiệt Trung ương từ tháng 1/2020 đến 6/2022. Kết quả: - Thời gian thời nằm bình lần lượt là 17,88 ± 7,29 31,76 16 (ngày). Sau có 80,29% đáp ứng về lâm sàng, tỷ lệ không 22,41%. Tỷ...

BACKGROUND Herpes simplex virus resistance to acyclovir is well described in immune-compromised patients. Management of prolonged infection and recurrences in such patients may be problematic. METHODS A patient with neuroblastoma developed likely primary herpes gingivostomatitis shortly after starting a course of chemotherapy, with spread to the eye during treatment with acyclovir. Viral isol...
