Alcohol: when combined with Divascol, it will cause accumulation of acetaldehyde in the liver leading to liver toxicity and creating a feeling of fear of alcohol. Epinephrine, norepinephrine: when combined with Divascol leads to a severe paradoxical drop in blood pressure and especially when used in high doses causes a very strong rebound in blood pressure. Dopamine: When combined with Divascol, blood pressure drops dramatically. Ranitidine: When combined with Divascol, the effect of reducing pulmonary vascular resistance and general circulation is ineffective, leading to treatment failure. In summary, Divascol is a drug containing the active ingredient Tolazoline used to reduce pulmonary vascular resistance in persistent pulmonary hypertension in neonates and patients with peripheral vasospasm disorders.
