Dissolving polymeric microneedle arrays for enhanced site-specific acyclovir delivery.

Acyclovir is widely indicated for the treatment of herpes labialis (cold sores), typically caused by the herpes simplex virus type 1 (HSV-1). However, topical acyclovir has poor efficacy, due to its low skin permeability. The purpose of this study was, therefore, to evaluate the ability of dissolving polymeric microneedle (MN) arrays to improve the local delivery of acyclovir. Acyclovir-loaded dissolving MN arrays (0.49 cm) were formulated from aqueous blends of Gantrez S-97 with 361 needles per array (58...

Crystal structure of Escherichia coli purine nucleoside phosphorylase complexed with acyclovir.

Escherichia coli purine nucleoside phosphorylase (PNP), which catalyzes the reversible phosphorolysis of purine ribonucleosides, belongs to the family I hexameric PNPs. Owing to their key role in the purine salvage pathway, PNPs are attractive targets for drug design against some pathogens. Acyclovir (ACV) is an acyclic derivative of the PNP substrate guanosine and is used as an antiviral drug for the treatment of some human viral infections. The crystalline complex of E. coli PNP with acyclovir was prepare...

Successful Therapy of Severe Oro-Labial Herpes Simplex With Muco-Adhesive Acyclovir.

Although muco-adhesive acyclovir 50mg tablets are only approved for the management of recurrent oro-labial HSV-1 infections, their ability to achieve extremely high concentrations in saliva and oral tissues suggests the potential for other uses. In this case, the agent was successfully utilized as a single tablet monotherapy leading to rapid clinical resolution of severe post-operative oro-labial infection. J Drugs Dermatol. 2018;17(4):479-480..

Acyclovir inhibits Cyprinid herpesvirus 3 multiplication in vitro.

Cyprinid herpesvirus 3 (CyHV-3), also known as koi herpesvirus (KHV), is an aetiological agent of a virulent and lethal disease in common and koi carp. In this study, we examined in vitro the anti-CyHV-3 activity of acyclovir (ACV), nucleoside analogue commonly used against human herpesviruses, as well as acyclovir monophospate (ACV-MP). The cytotoxicity of the ACV and the ACV-MP for two common carp cell lines, CCB (Common carp brain) and KF1 (Koi carp fin 1), was determined by means of MTT and crystal vio...

The effect of rate of injection on injection pressure profiles measured using in-line and needle-tip sensors: an in-vitro study.

Alongside ultrasonic visualisation, measurement of injection pressure is an effective tool for reducing the risk of intraneural injection during peripheral nerve block. The aim of this study was to compare injection pressure profiles when measured along the injection line with the pressure measured directly at the needle tip using different rates of injection. A syringe pump delivered a 5-ml injection of saline into silicone gel at three different speeds (5 ml.min , 10 ml.min and 15 ml.min ). Fibreoptic ...

Effect of Biphenyl Hydrolase-Like (BPHL) Gene Disruption on the Intestinal Stability, Permeability and Absorption of Valacyclovir in Wildtype and Bphl Knockout Mice.

Biphenyl hydrolase-like protein (BPHL) is a novel human serine hydrolase that was originally cloned from a breast carcinoma cDNA library and shown to convert valacyclovir to acyclovir and valganciclovir to ganciclovir. However, the exclusivity of this process has not been determined and, indeed, it is possible that a number of esterases/proteases may mediate the hydrolysis of valacyclovir and similar prodrugs. The objectives of the present study were to evaluate the in situ intestinal permeability and stabi...

Identification of a Syndemic of Blood-Borne Disease Transmission and Injection drug Use Initiation at the US-Mexico Border.

Efforts to prevent injection drug use (IDU) are increasingly focused on the role that people who inject drugs (PWID) play in the assistance with injection initiation. We studied the association between recent (i.e., past 6 months) injection-related HIV risk behaviors and injection initiation assistance into IDU among PWID in the U.S.-Mexico border region.

Frequency and factors associated with providing injection initiation assistance in Tallinn, Estonia.

Injection drug use is expanding in numerous regions in the world. Persons who inject drugs (PWID) play an important role encouraging new persons into injecting, by providing injection initiation assistance ("assisting" behaviors) and stimulating interest in injection ("promoting" behaviors).

A physiologically based pharmacokinetic model for valacyclovir established based on absolute expression quantity of hPEPT1 and its application.

In this study, a physiologically based pharmacokinetic (PBPK) model was established for valacyclovir based on absolute expression quantity of hPEPT1 along the entire length of the human intestine and other reliable in vitro, in vivo observed data. The PBPK model-3 defined acyclovir as metabolite of valacyclovir and simulated the plasma concentration-time profiles of valacyclovir and acyclovir simultaneously. It was validated strictly by a series of observed plasma concentration-time profiles. The average fo...

The Feasibility Determination of Risky Severe Complications of Arterial Vasculature Regarding to the Filler Injection Sites at the Tear Trough.

The tear trough is a significant sign of the eye and periorbital aging and has been usually corrected with filler injection. However, the arterial supply surrounding the tear trough could be inadvertently injured during injection; therefore, this study aimed to evaluate the nearest arterial locations related to the tear trough and investigate the possibility of severe complications following filler injection.

Acute neural hearing loss after cervical spine injection treatment.

This article presents the case of a 39-year-old woman receiving injection therapy for cervicalgia. Due to accidental injection into the cervical spinal cord, the patient suffered from syncope, sensomotoric deficit, and bilateral neural hearing loss. Injection therapies for spinal disorders are routinely carried out in clinical practice, despite a low level of evidence and potentially severe complications. In the event of neuro-otologic complications, prompt evaluation by an otologist should be sought and ...

Would intravitreal bevacizumab injection increase risk of cerebral infarction?

Although studies have evaluated the relationship between intravitreal bevacizumab (IVB) injection and cerebral infarction(CI), the effects of IVB on CI are still not clear. The aim of this study was therefore to investigate the effects of IVB injection on CI patients with age-related macular degeneration (AMD).

Intramuscular injection CLIMAT pathway: a clinical practice guideline.

The intramuscular (IM) injection has been part of nursing practice since the 1960s. Over the past 60 years, the practice of aspiration during IM injection has been controversial and understudied. In 2016, a study by Thomas et al identified that blood aspiration does occur during injection. This article introduces a clinical practice guideline for safe and effective aspiration during IM injection, as a follow-up to the findings of that study. The proposed guideline acknowledges the correct practice of aspira...

Detection of Intravascular Injection During Cervical Transforaminal Epidural Injection: A Comparison of Digital Subtraction Angiography and Real Time Fluoroscopy.

Transforaminal epidural injection (TFEI) with local anesthetics and steroids are effective in treating spinal radicular pain. However, inadvertent intravascular injection can lead to severe neurologic complications. To reduce complications of intravascular injection, use of imaging modality, such as real-time fluoroscopy (RTF) or digital subtraction angiography (DSA), has been recommended. DSA is an imaging technique that can clearly visualize the blood vessels from surrounding bones or dense soft tissues b...

Assessment of safe injection practices in health facilities in Oman.

Unsafe injection practices put patients and providers at risk of infectious and noninfectious adverse events. A 2001 Ministry of Health survey on injection practices in Oman indicated that, while overall standards were good, in some areas there was a need for improvement.

Randomized Controlled Trial of Belladonna and Opiate Suppository during Intravesical Onabotulinum Toxin A Injection.

Intravesical injection with onabotulinum toxin A (BTX-A) injection can be performed in-office under local anesthesia. Rectally administered pain medication presents a potentially feasible and previously uninvestigated adjunct to office-based anesthesia protocols.

Idiosyncratic reaction after injection of polyacrylate - polyalcohol copolymer.

Polyacrylate-polyalcohol copolymer is a synthetic product, non-biodegradable, with low rate of therapeutic failure and lower incidence of reactions at the site of injection, when compared to biodegradable agents. We report an unprecedent, exuberant and persistent inflammatory reaction following injection of that substance.

Exploring what shapes injection and non-injection among a sample of marginalized people who use drugs.

Few studies have specifically explored what influences people who use drugs to consume them in certain ways (i.e., smoking, injecting). While a great deal of research has examined the transition from non-injection to injection routes of drug administration, less is known about people who use drugs (PWUD) but have never injected or have stopped injecting. This paper draws on actor-network theory to explore what moves people to inject or not, among both people who currently smoke/sniff drugs (PWSD) and people...
