Vasodilation peripheral, with alcohol

Nicotinyl alcohol (3-pyridinylcarbinol, 3-pyridinemethanol) (27) has use as an antilipemic and peripheral vasodilator. It is available from either the reductions of nicotinic acid esters or preferably, the reduction of the nitrile to the amine followed by dia2otation and nucleophilic displacement. It is frequently adininistered in the form of the tartrate (Eig. 7). Nicotinic acid is frequently used as a salt in conjunction with basic dmgs such as the peripheral vasodilator xanthinol niacinate (28). Nicotinic acid and its derivatives have widespread use as antihyperlipidemic agents and peripheral vasodilators (1). 

Studies in subjects given alcohol 0.6 or 0.7 g/kg found that the effect of alcohol on blood pressure was unchanged by tadalafil 20 mg, although some subjects experienced dizziness and postural hypotension. In addition, the effects of alcohol on cognitive function were unchanged by tadalafil 10 mg. The pharmacokinetics of tadalafil 10 or 20 mg and alcohol were also unaffected by concurrent use. However, the manufacturers say that because both alcohol and tadalafil can cause peripheral vasodilation, additive blood pressure lowering effects are possible, especially with substantial amounts of alcohol (5 units) and the US manufacturer states that this may result in postural hypotension, increased heart rate, dizziness and headaehe. Aleohol may also affect the ability to have an erection. ...
