R-30490 is a medication that is commonly used to treat certain conditions. It belongs to a class of drugs known as beta-blockers. Beta-blockers work by blocking the effects of adrenaline, a hormone that increases heart rate and blood pressure.


R-30490 is primarily prescribed for the following indications:

1. Cardiovascular diseases: R-30490 is commonly used to treat high blood pressure (hypertension), angina pectoris (chest pain due to reduced blood flow to the heart), and heart failure.

2. Anxiety disorders: In some cases, R-30490 is prescribed for anxiety disorders, such as social anxiety and performance anxiety.

3. Tremor: R-30490 may also be prescribed to treat essential tremor, a neurological disorder that causes involuntary shaking.

Mechanism of Action

R-30490 works by selectively blocking specific beta-adrenergic receptors in the heart, blood vessels, and nervous system. By doing so, it reduces the workload on the heart, lowers blood pressure, and slows down the heart rate.

Dosage and Administration

The recommended dosage and administration of R-30490 may vary depending on the condition being treated and the individual’s response. It is usually taken orally, either once or twice a day. It is important to follow the prescribed dosage instructions provided by your healthcare provider.

Side Effects

While generally safe and effective, R-30490 may cause some side effects. These may include:

1- Fatigue: Feeling tired or weak is a common side effect of R-30490.

2- Low blood pressure: Some people may experience low blood pressure, especially during the first few doses.

3- Slow heart rate: R-30490 can slow down the heart rate, which may result in lightheadedness or dizziness.

4- Digestive issues: Stomach upset, nausea, and constipation may occur.

5- Sleep disturbances: R-30490 can interfere with sleep, leading to difficulty in falling asleep or staying asleep.

6- Sexual dysfunction: In rare cases, R-30490 may cause erectile dysfunction or loss of libido.

Precautions and Contraindications

It is important to inform your healthcare provider about any other medications you are taking, including over-the-counter medications, herbal remedies, and supplements. R-30490 may interact with certain drugs and alter their effectiveness.

Certain medical conditions and factors may contraindicate the use of R-30490, including:

1- Heart failure: R-30490 may not be suitable for individuals with severe heart failure.

2- Low blood pressure: People with hypotension (low blood pressure) should not take R-30490 without medical supervision.

3- Slow heart rate: Individuals with bradycardia (slow heart rate) or heart block should not use this medication.

4- Pregnancy and breastfeeding: R-30490 should be avoided during pregnancy and breastfeeding unless prescribed by a healthcare professional.


R-30490 is a medication commonly prescribed for various conditions. While its mechanisms of action and indications are well understood, it is important to consider potential side effects and consult with your healthcare provider before starting treatment.
