Topical delivery of local anaesthetic drugs such as Lidocaine HCl using carriers and novel nanotechnology can enhance effective drug permeation through the skin into deeper layers and exhibit desirable duration of action. The present study was aimed to formulate and evaluate Lidocaine HCl loaded cubosomes (LHLCs) for sustained therapeutic topical action. Cubosomes emanated as favourable means for the delivery of the drug. LHLCs were prepared by top-down technique using lipid and polymer. Eight formulations of LHLCs were prepared using different concentrations of glyceryl monooleate (GMO) and Poloxamer 407 (P-407). Local anaesthetics create loss of sensation in particular region of the body by inhibiting impulse generation and propagation. Lidocaine HCl is most commonly used amino amide local anaesthetic. It is used as local, topical, intravenous, epidural, peripheral and spinal anaesthesia. The prepared cubosomal dispersions were evaluated to determine surface morphology, particle size, poly dispersibility index (PDI), zeta potential, entrapment ability, tissue distribution studies, and in vitro drug release studies. Scanning Electron Microscopic analysis confirmed that drug was encapsulated in bicontinuous structure. The maximum entrapment efficiency was found to be 89.85±1.1% with vesicle size as 228±2.1nm, charge as -5.68±2.7, PDI as 0.295 and 98.83%± 0.12 in vitro drug release at the end of 12 hr for F7 formulation, which was confirmed as optimized cubosomal dispersion.

Abstract Background Tonsillectomy is one of the most common procedures in otorhinolaryngology practice where analgesics are required for pain-relief especially in children. To compare the efficacy of using peritonsillar infiltration of lidocaine Hcl versus intravenous preincisional lornoxicam in reducing post tonsillectomy pain. Results Prospective, randomized, double-blinded, placebo-controlled study. Ninety-nine patients from age 12 to 18 years old, prepared for tonsillectomy. Patients were randomly subdivided into three groups as 33 patient in each group to receive either lidocaine (group 1), lornoxicam (group 2), or saline as a placebo (group 3). Anesthesia was induced using intravenous fentanyl and propofol, while endotracheal intubation was facilitated with rocuronium and maintenance by halothan. Intraoperative bleeding, pain scores, interval until first order for analgesic. The postoperative complications including bleeding, hypoxia, nausea, and vomiting also were observed. Pain scores at rest were significantly lower in group 2 than groups 1 and 3 at all observation times. Similarly, pain scores were lower in group 2 during the first 5 postoperative hours. The mean time for rescue analgesic was 276 min in group 2, 91 min in group 1, and about 60 min in group 3. No significant differences were noted for intraoperative bleeding. Conclusion The use of lornoxicam 16 mg at preoperative phase gave good control of immediate post tonsillectomy pain. Level of evidence 3b

Fibromyalgia (FM) patients usually are resistant to conventional single mode therapy. Therefore, the efficacy of combined pharmacological and nonpharmacological treatments for the management of FM symptoms in a clinical population was assessed. Participants were injected with 4x5 mL 1% lidocaine HCl solution and given education materials and support on increasing their daily steps walked and to engage in mindfulness techniques to reduce their overall pain and accompanying symptoms of their condition. Participants self-reported pain intensity, unpleasantness, anxiety, fatigue, and depression three days prior to and after each injection. Overall ratings of pain intensity and unpleasantness showed statistically significant reductions of 34.7 and 47.2 percent respectively with the combined use of treatments. Additionally, fatigue levels had a significant decrease but depression and anxiety ratings were not significantly modified by this treatment modality. Patients who had a greater adherence to their protocol had an improved pain relief when compared to others. These results suggest that the use of a combination treatment method for FM in a clinical setting and when used in combination is effective. This pilot study can be used as a model for future randomized controlled studies on comprehensive treatments for FM.

Aim: Anxiety and intolerance to dental local anesthetic injections are common in patients undergoing dental procedures. This work was designed to study cytotoxicity of selected flavors in primary gingival keratinocytes (PGK), to acquire information on their suitability for use in dental lidocaine hydrochloride (LID) injection. We also evaluated the bio-mimetic taste of LID dental injection in the presence of selected flavors and sweetener using an Astree electronic tongue (ETongue). Methods: The cytotoxicity of chocolate natural and artificial flavor (CTE), raspberry flavor artificial (RAS), cherry flavor (CHR), bitterness suppressor flavor (BSF) and lemon flavor extract (LFE) at various dilutions (0.16–10% v/v) was carried out in PGK using the live cell morphological analysis and MTT cell cytotoxicity assay. Based on the cytotoxicity data, CTE and RAS were added to Xylocaine® (2%) along with 0.09% sodium saccharin and taste was assessed using an ETongue. Results: After three hours of treatment, a dose-dependent cell death was induced by all flavors compared to the untreated control. BSF was found to be more toxic when compared to other flavors. CTE was found to be less toxic. The mean IC50 values of CTE, RAS, CHR, BSF and LFE in PGK were found to be 9.54, 8.43, 2.21, 0.38 and 4.01 mg/mL. Taste analysis with the ETongue showed a clear taste difference between the control and test formulations containing CTE and RAS flavors along with sodium saccharin. Conclusion: CTE and RAS flavors in combination with 0.09% sodium saccharin can achieve a significant taste-masking effect in the dental LID injection.

Microneedles are emerging drug delivery methods for painless treatment. The current study tested dissolving microneedles containing lidocaine (Li-DMN) for use in local anesthesia. An Li-DMN patch was fabricated by centrifugal lithography with carboxymethyl cellulose as a structural polymer and assessed for physical properties by optical microscopy and a fracture force analyzer. The biocompatibility was evaluated by a histology section in vitro and by ear thickness in vivo. The efficacy of the Li-DMN patch was assessed by electrophysiological recordings in primary cultured sensory neurons in vitro and a von Frey test on rats’ hind paws in vivo. The physical properties of the microneedle showed enough rigidity for transdermal penetration. The maximal capacity of lidocaine-HCl in the Li-DMN patch was 331.20 ± 6.30 µg. The cytotoxicity of the dissolving microneedle to neuronal cells was negligible under an effective dose of lidocaine for 18 h. Electrophysiological recordings verified the inhibitory effect of the voltage-gated sodium channel current by the Li-DMN patch in vitro. A skin reaction to the edema test and histologic analysis of the rats’ ears after application of the Li-DMN patch were negligible. Also, the application of the Li-DMN patch reduced the nocifensive behavior of the rats almost immediately. In conclusion, the dissolving microneedle patch with carboxymethyl cellulose is a promising candidate method for the painless delivery of lidocaine-HCl.
