There is no good evidence, experimental or clinical, to justify the simultaneous administration in fixed proportion of two vasodilators like sodium nitrite and glyceryl trinitrate (nitroglycerin).
There is probably, however, no better nitrite or nitrate than nitroglycerin.
The only value of the nitrites is when the blood pressure is high and the nitrite action is desired on that account.

The amyl nitrite should be in the emergency case of the physician in the form of ampules, or may be carried by the patient after he has had one or more attacks.
If amyl nitrite is not at hand, or has been found previously to cause considerable disturbance of the head or a feeling of prolonged faintness, nitroglycerin is the next most rapidly acting drug.
In diseases of the heart the sudden vasodilation caused by amyl nitrite inhalations is indicated only in angina pectoris.
Whether nitroglycerin or other nitrite is advisable depends on the peripheral blood pressure.
Amyl nitrite may be inhaled with the same object in view, but the action is very intense, the prostration often severe, and unless there is angina pectoris, nitroglycerin is much better.
These two kinds are known as the nitrite bacteria and the nitrate bacteria.
Müntz held that the conversion of nitrite into nitrate is brought about by the joint action of carbonic acid and oxygen.
By one (nitrosomonas) ammonia is converted into nitrite; by the other (nitrobacter) the nitrite is converted into nitrate.
To purify the salt completely, the nitrite should be changed into nitrate by nitric acid; but then sulphate of soda would remain as an impurity formed from sulphuret in the ore, and no attempt to separate this has as yet succeeded.
Water then dissolves out seleniate nitrate and nitrite of soda, no selenium remaining in the residue.
In such cases it is necessary to gain time until digitalis and alcoholics can unfold their action, and here nitrite of amyl stands pre-eminent.
