What does GTN mean in LABORATORY

Glyceryl TriNitrate (GTN) is a nitrate drug used to treat chest pain caused by angina. It works by relaxing the blood vessels and improving blood flow in the heart, so it can more easily pump oxygen-rich blood throughout the body. GTN can also be used to treat other types of heart problems and some forms of pulmonary hypertension.

GTN works by increasing levels of cyclic guanosine monophosphate (cGMP). cGMP is a compound that helps relax muscle cells in the walls of your arteries, allowing blood vessels to widen and improve circulation throughout your body. GTN also blocks an enzyme called phosphodiesterase 5 (PDE5), which can further help relax muscles and improve circulation.

Common side effects associated with taking GTN include headache, dizziness, hypotension, flushing, nausea, vomiting, abdominal discomfort, rash or itching. Less serious side effects may include fatigue or drowsiness. In rare cases, more severe side effects such as difficulty breathing or swelling can occur.

You should take GTN exactly as prescribed by your doctor. Most often, you will take it one to two minutes before engaging in activity or exercise that would normally cause chest pain from angina. If you are using it for another type of heart problem or pulmonary hypertension, follow your doctor’s instructions carefully about when and how much to take.

Avoid drinking alcohol while taking GTN since it could increase the chance of low blood pressure and dizziness associated with taking this medication. Other than that, there are no dietary restrictions for taking GTN; however you should always talk to your doctor about any dietary concerns you may have related to this medication or other medications you may be taking at the same time.

Certain medicines could interact with each other if taken together so it is important to make sure your doctor knows all medications you are currently taking before starting on a course of therapy with classed nitrates like GTK You should not take certain drugs such as sildenafil (Viagra®), tadalafil (Cialis®) or vardenafil (Levitra®) while taking classed nitrates like GTK since they could lower your blood pressure too much.

No; if you are prescribed glyceryl trinitrate for a chronic condition such as angina then it is important that you continue to take this medication as prescribed by your doctor even if symptoms improve over time as suddenly stopping treatment without consulting them first could cause serious health problems including worsening chest pains due to blocked arteries and increased risk of stroke and heart attack due to narrowed arteries resulting in decreased oxygen supply to vital organs such as brain and heart muscles respectively.

Yes; Before starting on any new medications make sure tell your doctor about any medical conditions you have especially those related to narrow angle glaucoma; diabetes; asthma; emphysema; hyperthyroidism; peptic ulcer disease; high cholesterol levels etc., Also inform him/her about any allergies or reactions especially towards other nitrates like amylnitrite and pentaerythritoltetranitrate before beginning therapy.

The duration of action depends upon factors such as formulation type i.e., slow release tablets tend act slower but last longer compared immediate release tablets followed closely by sublingual sprays whereas transdermal patches last longest 12-18 hours . Generally it starts working within minutes after administration & its effect is usually felt over next 10-15 minutes thereafter so seek medical attention immediately if symptoms persist or increase.
