A randomized, double-blind, placebo-controlled trial of cidofovir gel for the treatment of acyclovir-unresponsive mucocutaneous herpes

This study was designed to determine the antiviral activity in cervicovaginal lavage (CVL) samples collected after intravaginal application of 0.5% PRO 2000 gel (Indevus). BACKGROUND Globally, herpes simplex virus type 2 (HSV-2) infection is the most common cause of genital ulcer disease. Ten of 20 cidofovir-treated and none of 10 placebo-treated patients had complete healing or >50% decreased area (P = .008); 30% of cidofovir-treated patients versus 0 placebo recipients had complete healing (P = .031). B6-CXCR2 KO mice (n = 19) were compared with wild-type B6 mice (n = 18) for corneal opacity (A) and corneal neovascularization (B). A leading candidate, VivaGel (SPL7013 Gel) is the product of nanotechnology. Caffeine inhibited plaque formation of HSV-2 and acyclovir-resistant HSV-1 strains and their EC50 values ranged from 0.42 to 1.11 mg/ml. This study compared the biological activity and concentration of PRO 2000 in cervicovaginal lavage (CVL) collected in the absence or following coitus.

Edition, September 10, 2010 A new topical antiviral treatment for acute herpetic keratitis and corneal scarring associated will soon be Widely available to patients in the U. Our studies demonstrated the maximal HB-13 concentration was 2.51 µg/mL, which was more than the half maximal inhibitory concentration (IC50) as we previously reported. In this double-blind, randomized, placebo-controlled trial, 40 patients were randomized to a polyethylene glycol (PEG) formulation containing 20% 2-HPβCD or to a vehicle control arm. A leading candidate, VivaGel (SPL7013 Gel) is the product of nanotechnology. So having oral to oral, vaginal, active ingredient springs dose, skip the resides in the in men (almost resides in the. This virus is classified according to different host species, replication cycle time, and its capacity to decompose the cell it infects. However, above pH 3.8, there was an exponential increase in viscosity which is consistent with what is known about Carbopol-based gels alone in aqueous vehicles.

VivaGel®, a topical gel containing 3% w/w SPL7013, has been shown to be safe and well-tolerated in human clinical studies. Notably, their approach offers the first viable way for women to actively protect themselves from HIV infection without having to persuade a partner to use a condom. I have always used Red marine Algae and Other Seaweeds as the foundation of my Antiviral gels and I know also inlcude these seaweeds in my men’s and women’s immune formulas. Using a plaque reduction assay, the polysaccharide at 100 microg/ml was active against the herpes simplex virus types 1 and 2 (HSV-1 and HSV-2), but was inactive against cytomegalovirus, the human influenza virus types A and B, the poliovirus type 1 or the vesicular stomatitis virus. The modalities evaluated include topical agents such as immune response modifiers (imiquimod, resiquimod, and interferon), antivirals (penciclovir, cidofovir, and foscarnet), sinecatechins, microbiocidals (SPL7013 gel, and PRO 2000 gel), along with experimental (oligodeoxynucleotides), immunoprophylactic, and immunotherapeutic vaccines. Digestion of sucrose gradient purified virions for 4 h with neuraminidases that remove both alpha2,3 and alpha2,6 linked sialic acids reduced titers by 1,000-fold. Cidofovir was put into the form of a vaginal gel, using mucoadhesive and thermosensitive polymers such as chitosan, Carbopol 974P, HPMC, and poloxamer 407.

The first 10 residues of the N-terminal amino acid sequence are DNILFSDSTL. This was a multicenter, randomized, investigator-masked, parallel group study. We demonstrate that the concentration achieved intravaginally with a 1% tenofovir topical gel has direct antiherpetic activity. The antiretroviral-based microbicide gel contains  MIV-150, an enzyme inhibitor that prevents HIV-infected cells from producing new virus; zinc acetate, an antiviral agent with activity against HIV and herpes simplex virus (HSV); and carrageenan, a natural product derived from seaweed that has been shown to have potent activity against human papillomavirus (HPV). While male and female condoms are effective when used correctly, they are not practical for men and women who cannot negotiate condom use and for women and couples who want to have children. These lignin-carbohydrate complexes (LCs) showed antiviral activities against herpes simplex virus types 1 and 2 (HSV-1 and -2), human cytomegalovirus (HCMV) and measles virus. – La peroxydation de ces huiles est un procédé spécifique, impliquant l’injection d’oxygène dans des conditions de haute pression et de haute température.

Our objective is to develop a drug formulation that protects against both HSV-2 and HIV infection and adheres to the vaginal surface with extended residence time. In mice intravaginal infection with HSV-2 and the associated mortality was prevented completely when the infection was carried out in the presence of a 20 mM monocaprin containing gel formulation. Food and Drug Administration in September 2009, is a topical ophthalmic antiviral indicated for the treatment of acute herpetic keratitis (dendritic ulcers). Dr. However, I often find that people with STIs are much more concerned with protecting others than they are in protecting themselves. Before beginning any type of natural, integrative or conventional treatment regimen, it is advisable to seek the advice of a licensed healthcare professional.
