OBJECTIVES To characterize the uptake, washout, and metabolism of lidocaine hydrochloride in the iris/ciliary body and cornea. METHODS Iris/ciliary body uptake of lidocaine hydrochloride was measured by incubating human and rabbit irides in radiolabeled carbon 14-1% lidocaine hydrochloride for 2 to 60 minutes. Washout was determined by incubating the iris in 14C-1% lidocaine hydrochloride for...

BACKGROUND The efficacy of many preparations for topical use in herpes infections have remained rather disappointing. The development of new antiviral drugs, especially herbal preparations, thus remains desirable. In a screening study with plant extracts, a rhubarb root extract and a sage extract showed a promising activity. OBJECTIVE The efficacy of a combined topical preparation with rhubar...

In order to reveal some cytotoxic features of lidocaine, the effects of lidocaine at sublethal concentrations (10 mM or less) on rat thymocytes were examined by the use of flow-cytometric technique with fluorescent probes. Treatment with lidocaine at 3-10 mM for 1-3 hr significantly increased intracellular Ca and Zn concentrations under normal condition. After the removal of external Ca and Zn,...

BACKGROUND Topical anesthetics are commonly applied for a variety of indications. Several lidocaine-containing topical anesthetics are available for purchase over the counter (OTC). Recently, the authors' group has shown that there is great interindividual discrepancy in the manner in which lidocaine is absorbed and metabolized for even a single OTC product. OBJECTIVES The authors compare fiv...

This study assessed the effect of low (10 mg ⋅ kg-1 ⋅ h-1) and very high (18 mg ⋅ kg-1 ⋅ h-1) doses of lidocaine on defibrillation energy requirements (DER) to relate changes in indexes of sodium-channel blockade with changes in DER values using a dose-response study design. In group 1 (control; n = 6 pigs), DER values were determined at baseline and during treatment with 5% dextrose in water (...

OBJECTIVE To evaluate intravenous lidocaine's safety and efficacy as an analgesic agent in the treatment of a variety of painful conditions presenting to the emergency department. METHODS This case series identified seventeen patients who received lidocaine over a six month period and recorded demographic data, amount of lidocaine administered, the amount of opioid medication administered bef...

BACKGROUND Pain on injection of rocuronium is a common clinical problem. We compared the efficacy of lidocaine, ketorolac, and the 2 in combination as pretreatment for the prevention of rocuronium-induced withdrawal movement. METHODS For this prospective, randomized, placebo-controlled, double-blind study a total of 140 patients were randomly allocated to one of 4 treatment groups to receive ...

Mometasone furoate, a potent glucocorticoid (class III) with a favorable benefit/risk ratio, has emerged as a standard medication for the treatment of inflammatory skin disorders. The purpose of the investigation presented here was to determine the noninferiority of a topical mometasone formulation, a light cream (O/W 60/40 emulsion) with mometasone furoate 0.1% (water content of 33%) versus ma...

Sir, Urticarias unresponsive to antihistamines are frustrating for both physicians and patients. In severe cases, steroids or cyclosporine may be needed.[1] This retrospective observation highlights the potential of warfarin in managing chronic idiopathic urticaria (CIU). halobetasol ointment (P = 0.005), clobetasol ointment and halobetasol ointment (P = 0.015) and halobetasol cream and halobet...

Objective- This study was performed to investigate the analgesic effects of lidocaine and lidocaine/tramadol combination in epidural anaesthesia in dromedary camels. Design- Experimental Study Animals- Eight healthy immature dromedary camels Methods - The camels were randomly designed in 2 equal groups. In group L: lidocaine 2% (0.22 mg/kg) and in group LT: a combination of lidocaine 2% (0.22 m...
