Bisonol 2.5 mg contains Bisoprolol fumarate, a beta-1 selective adrenergic blocker used to manage cardiovascular conditions such as high blood pressure, angina pectoris, and chronic heart failure. It helps reduce the workload on the heart and improves its efficiency.

Mechanism of Action
Bisoprolol works by selectively blocking beta-1 adrenergic receptors in the heart. These receptors normally respond to stress hormones like adrenaline, which increase heart rate and force of contraction. By blocking them, Bisoprolol:

• Lowers heart rate

• Reduces cardiac output

• Decreases blood pressure

• Lowers the oxygen demand of the heart muscle
  This makes it beneficial in treating heart conditions that involve strain on the heart.

  Uses
  Bisonol 2.5 mg is used for:

  • Hypertension (high blood pressure)

  • Stable angina (chest pain due to reduced blood flow to the heart)

  • Chronic heart failure, often in combination with other heart medications

  • Post-myocardial infarction care to improve heart function and reduce future risk

    Adverse Effects
    While generally safe and effective, Bisoprolol may cause side effects in some individuals:

    • Fatigue, weakness, or drowsiness

    • Dizziness or light-headedness, especially when standing up

    • Slow heart rate (bradycardia) or low blood pressure

    • Cold hands and feet due to reduced peripheral circulation

    • Shortness of breath, especially in people with pre-existing lung conditions

    • Rarely, sleep disturbances or mild depression
