Oral: As usual for tablets and capsules, just put them in your mouth and take them with water; 2. Sublingual: Small pills are contained under the tongue to release the effect as soon as possible. In the first aid nitroglycerin is sublingual, this way of taking the drug has the advantage of allowing the drug to take effect quickly. Therefore, when choosing to take it, it is more convenient to take it orally if you are taking compound salvia drops for a long time. For acute attacks of chest congestion or angina pectoris, it is recommended to take the drug sublingually to achieve a rapid onset of action.
