Pacrinolol

From WikiMD's Wellness Encyclopedia

Pacrinolol is a non-selective beta blocker medication that is primarily used to treat high blood pressure (hypertension) and certain heart conditions. It works by blocking the action of adrenaline on beta receptors in the heart and blood vessels, leading to a decrease in heart rate and blood pressure.

Mechanism of Action[edit | edit source]

Pacrinolol acts by competitively blocking beta-1 and beta-2 adrenergic receptors. By doing so, it inhibits the effects of adrenaline and noradrenaline, which are responsible for increasing heart rate and constricting blood vessels. This results in a reduction in heart rate, cardiac output, and blood pressure.

Indications[edit | edit source]

Pacrinolol is indicated for the treatment of:

  • Hypertension
  • Angina pectoris
  • Arrhythmias
  • Myocardial infarction
  • Heart failure

Dosage and Administration[edit | edit source]

The dosage of pacrinolol may vary depending on the condition being treated and the individual patient's response. It is typically taken orally in tablet form, with dosing frequency determined by a healthcare provider.

Side Effects[edit | edit source]

Common side effects of pacrinolol may include:

  • Fatigue
  • Dizziness
  • Bradycardia (slow heart rate)
  • Hypotension (low blood pressure)
  • Cold extremities

Serious side effects that may require immediate medical attention include:

  • Bronchospasm
  • Heart block
  • Worsening heart failure
  • Allergic reactions

Contraindications[edit | edit source]

Pacrinolol is contraindicated in patients with:

  • Asthma or chronic obstructive pulmonary disease (COPD)
  • Severe bradycardia
  • Heart block
  • Cardiogenic shock

Precautions[edit | edit source]

Patients with a history of bronchospasm, heart failure, or diabetes should use pacrinolol with caution. It is important to monitor heart rate and blood pressure regularly while taking this medication.

Interactions[edit | edit source]

Pacrinolol may interact with other medications, such as:

  • Calcium channel blockers
  • Digoxin
  • Insulin
  • Nonsteroidal anti-inflammatory drugs (NSAIDs)
