Caustic paste disbudding is becoming more commonplace in North America. A large body of work has examined pain control for cautery disbudding and surgical dehorning, but fewer studies have evaluated pain control for caustic paste disbudding, and results conflict regarding benefits of local anesthesia. In humans, the pain associated with a caustic, chemical burn can differ in nature, duration, and intensity compared with a thermal burn. The objective of this clinical trial was to evaluate the effects of either a lidocaine cornual nerve block or a topical anesthetic incorporated into caustic paste on the acute pain of caustic paste disbudding...

BACKGROUND: Topical anesthesia is used to control pain associated with many procedures in medicine. Today, the product most commonly applied for topical anesthesia in Germany is EMLA(®) (lidocaine/prilocaine). However, since prilocaine is a methemoglobin-inducing agent, there are limitations to its use, especially in neonates and infants. The aim of this study was to evaluate the effect of prilocaine and lidocaine as well as propylene glycol, a penetration enhancer, and trometamol, a buffer substance, in anesthetic creams...

Tuning the bioavailability of lidocaine was explored by its incorporation into the ionic liquid lidocainium docusate ([Lid][Doc]) and the deep eutectic Lidocaine·Ibuprofen (Lid·Ibu) and comparing the transdermal absorption of these with the crystalline salt lidocainium chloride ([Lid]Cl). Each form of lidocaine was dissolved in a vehicle cream and topically applied to Sprague-Dawley rats. The concentrations of the active pharmaceutical ingredients (APIs) in blood plasma were monitored over time as an indication of systemic absorption...

BACKGROUND: Botulinum toxin-A (BTX) has numerous cosmetic and therapeutic applications. Our previous studies have found that BTX augments pedicled flap survival through both vasodilatory effects and attenuation of the inflammatory response to ischemia in the rat. This study examines the effect of chronic BTX on microcirculatory vascular tone and its response to acute topical vasodilators in muscle flaps. METHODS: The spinotrapezius muscle of Sprague-Dawley rats underwent a single 2-week pretreatment of 0...

(no author information available yet)
Although premature ejaculation is the most common ejaculation problem, it is poorly understood and currently has no standard definition.(1) Typically, it involves reduced time to ejaculation, inability to control or delay ejaculation and associated distress.(1-5) Treatments that have been assessed include psychosexual counselling, antidepressants (e.g. selective serotonin reuptake inhibitors), phosphodiesterase type-5 inhibitors, tramadol and topical anaesthetic agents (e.g. lidocaine/prilocaine cream). A new formulation (cutaneous spray) of lidocaine/prilocaine (Fortacin-Plethora Solutions Ltd...

Menthol is a naturally occurring terpene used as a penetration enhancer in topical and transdermal formulations. Literature shows a growing interest in menthol's interactions with the transient receptor potential melastatin 8. A decrease in extracellular Ca(2+) due to the activation of the transient receptor potential melastatin 8 receptor produces inhibition of E-cadherin expression that is responsible for cell-cell adhesion. Because calcium is present in the entire epidermis, the purpose of this study is to evaluate whether the aforementioned properties of menthol are also related to its penetration-enhancing effects...

Urethral catheterization is a predictor of agitation during the general anesthesia recovery period. The aim of this study was to determine the effect of intraurethral 5% lidocaine and 25 mg/g prilocaine cream in reducing catheter-related bladder discomfort (CRBD) in male patients during the general anesthesia recovery period. Adult male patients undergoing elective operations that required urinary catheterization under general anesthesia were enrolled and assigned randomly to 2 groups. In the lidocaine-prilocaine cream group (n = 72), approximately 5 g of topical cream was spread in the preputial sac, the glans, the meatus, and on the urinary catheter surface before urinary catheterization...

OBJECTIVES: Almost 20 years after Cartwright et al. (1996) demonstrated the feasibility and effectiveness of clinic meatotomy (CM) under topical lidocaine and prilocaine (EMLA) anesthesia, 50% of meatotomies are still performed under general anesthesia (GA) (Godley et al., 2015). The cost of a meatotomy under GA is approximately 10 times the cost of CM in the present practice. This study presented the outcomes for CM under topical anesthesia, in consecutive patients who presented with meatal stenosis secondary to circumcision...

Topical gels compounded by pharmacists are important clinical tools for the management of pain. Nevertheless, there is often a dearth of information about the chemical stability of drugs included in these topical formulations, complicating the assignment of beyond-use dating. The purpose of this study was to develop a high-performance liquid chromatography photodiode array-based stability-indicating assay that could simultaneously resolve six drugs (amitriptyline, baclofen, clonidine, gabapentin, ketoprofen, lidocaine) commonly included in topical gels for pain management and their potential degradation products...

The purpose of this study was to evaluate the skin permeation of tricyclic antidepressants (TCAs) with propamine moiety to select candidates for the development of topical analgesics to treat cutaneous pain. We sought to establish the structure-permeation relationship (SPR) of topical TCAs. The lipophilicity, melting point, and aqueous solubility were determined to develop the physicochemical characterization. The TCA permeation into pig and nude mouse skins was estimated using Franz diffusion cell. TCAs and lidocaine were comparatively examined for cutaneous analgesia by pinprick assay...

OBJECTIVE: The use of topical local anesthetics in the form of creams, gel or spray is the oldest method of retarding ejaculation. However, several studies have suggested that phosphodiesterase type 5 inhibitors (5-PDEiS) show a potential therapeutic use in the treatment of premature ejaculation (PE). The aim of this study was to compare the efficacy and tolerability of tadalafil-only, tadalafil plus local anesthetic spray (lidocaine), and topical lidocaine spray-only before intercourse on the intravaginal ejaculatory latency time (IELT) of patients with lifelong PE...

BACKGROUND: In unilateral neuropathic pain. e.g. after peripheral nerve injury, both positive and negative sensory signs occur often, accompanied by minor but equally directed contralateral sensory changes. To mimic this feature, we experimentally aimed to induce concomitant c-fibre sensitization and block in healthy subjects and analyzed the bilateral sensory changes by quantitative sensory testing (QST) using the protocol of the German Research Network on Neuropathic Pain. METHODS: Twenty eight healthy subjects were firstly randomized in 2 groups to receive either topical capsaicin (0...
