Propranolol ER 120 mg delivers a consistent level of the medication over an extended period, typically 12 hours. This contrasts with immediate-release formulations, which act quickly but wear off sooner.
Absorption and Elimination
The extended-release design ensures a slower absorption rate compared to standard propranolol. This leads to fewer peaks and valleys in blood propranolol levels, minimizing the risk of side effects associated with rapid fluctuations.
Elimination follows a similar pattern; the drug is released gradually, leading to a more stable plasma concentration. This extended profile offers benefits for managing conditions requiring consistent drug levels. Regular blood tests may be required to monitor the drug’s effect. Follow your doctor’s instructions carefully.
Managing Side Effects
Common side effects of propranolol include fatigue, dizziness, and nausea. The extended-release formulation aims to reduce the intensity of these by providing a steadier blood concentration. However, individual reactions vary. Report any persistent or worsening side effects to your physician immediately.
Important Considerations
Never crush, chew, or break extended-release capsules. Doing so compromises the controlled-release mechanism, leading to potentially harmful peaks in blood levels and increased side effects. Always swallow the capsule whole with a full glass of water.
Dosage Adjustments
Your doctor will determine the appropriate dosage based on your specific health condition and response to the medication. Dosage adjustments are made gradually to minimize side effects and optimize therapeutic benefit. Strictly adhere to the prescribed dosage and schedule; do not alter your medication without consulting your physician.
