BACKGROUND There are 3 new topical treatments for herpes labialis that have either been approved by the US Food and Drug Administration (penciclovir cream [Denavir] and n-docosanol cream [Abreva]) or recently undergone extensive clinical evaluation (acyclovir cream). The relative efficacy of these products is unknown. OBJECTIVE To compare the efficacy of penciclovir cream, acyclovir cream, n-...

OBJECTIVES The aim of the present study was to elucidate the mechanism of cutaneous vasodilation following acupuncture stimulation by investigating the roles of nitric oxide (NO) and axon reflex vasodilation. METHODS The subjects were 17 healthy male volunteers. The role of NO was investigated by administering N(G)-nitro-l-arginine methyl ester hydrochloride (L-NAME, 20 mM), an NO synthase in...

BACKGROUND Tumescent lidocaine anesthesia consists of subcutaneous injection of relatively large volumes (up to 4 L or more) of dilute lidocaine (≤1 g/L) and epinephrine (≤1 mg/L). Although tumescent lidocaine anesthesia is used for an increasing variety of surgical procedures, the maximum safe dosage is unknown. Our primary aim in this study was to measure serum lidocaine concentrations after ...

Objective- To compare the lidocaine-MgSO4 combination with lidocaine-Distilled water inthe epidural of indigenous awake dogs.Design- Prospective experimental study.Animals- Five young (12±2 months) female indigenous dogs weighting (10.74 ± 0.44 kg).Procedures- Epidural anesthesia was produced in all dogs with 2% lidocaine (1ml/4.5 kgbody weight) with 1 ml distilled water and two weeks later rep...

The roles of cytochrome P-450 (CYP) enzymes in the N-deethylation, i.e., formation of monoethylglycinexylidide (MEGX), and 3-hydroxylation of lidocaine were studied with human liver microsomes and recombinant human CYP isoforms. Both CYP1A2 and CYP3A4 were found to be capable of catalyzing the formation of MEGX and 3-OH-lidocaine. Lidocaine N-deethylation by liver microsomes was strongly inhibi...
