The interaction of Ro15-4513 (5 mg/kg) with ethanol (3 g/kg, 60%w/v bolus) in dogs was investigated. Ro15-4513 challenge 120 minutes after a single ethanol dose had no significant effect on blood ethanol concentration or heart rate. In the same experiment, (1) blood acetaldehyde concentration was elevated to more than double the control value (vehicle only, no Ro15-4513), and (2) systolic blood pressure decreased to less than 60% of control. Further investigation revealed: (1) after Ro15-4513, area under the blood acetaldehyde vs time curve was more than twofold greater (p = 0.0006) than control, and the area under the systolic blood pressure vs time curve was 76% (p = 0.0027) of control. Based on these results, we propose that an inter-relationship exists between Ro15-4513, blood acetaldehyde concentration, and systolic blood pressure in ethanol intoxicated dogs.

UI	MeSH Term	Description	Entries
D008658	Inactivation, Metabolic	Reduction of pharmacologic activity or toxicity of a drug or other foreign substance by a living system, usually by enzymatic action. It includes those metabolic transformations that make the substance more soluble for faster renal excretion.

D000079	Acetaldehyde	A colorless, flammable liquid used in the manufacture of acetic acid, perfumes, and flavors. It is also an intermediate in the metabolism of alcohol. It has a general narcotic action and also causes irritation of mucous membranes. Large doses may cause death from respiratory paralysis.	Ethanal
D000431	Ethanol	A clear, colorless liquid rapidly absorbed from the gastrointestinal tract and distributed throughout the body. It has bactericidal activity and is used often as a topical disinfectant. It is widely used as a solvent and preservative in pharmaceutical preparations as well as serving as the primary ingredient in ALCOHOLIC BEVERAGES.
