This comprehensive guide provides essential information on various medications, including their uses, mechanisms of action, contraindications, and health implications. Understanding these aspects is crucial for safe and effective medication management.

GTN Spray (Glyceryl Trinitrate)

GTN spray is commonly used to relieve chest pain (angina) by dilating blood vessels and improving blood flow to the heart.

Mechanism of Action

GTN works by releasing nitric oxide, which relaxes blood vessels, reducing the heart’s workload and relieving chest pain.

Contraindications

Severe hypotension (low blood pressure)
Recent head trauma or stroke
Use of erectile dysfunction medications (e.g., Viagra)
Severe anaemia

For further details, visit the GTN Spray page.

Statins

Statins are medications used to lower cholesterol levels and reduce the risk of cardiovascular disease.

Mechanism of Action

Statins work by inhibiting the enzyme HMG-CoA reductase, which is involved in cholesterol production in the liver.

Contraindications

Liver disease
Pregnancy and breastfeeding
Severe muscle disorders

For more information, visit the Statins page.

Adrenaline (Epinephrine)

Adrenaline is a life-saving medication used in severe allergic reactions (anaphylaxis) and cardiac arrest.

Mechanism of Action

Adrenaline works by stimulating the heart and constricting blood vessels, improving blood pressure and breathing.

Contraindications

None in life-threatening emergencies
Use with caution in heart disease
Monitor for severe hypertension
