What is Calan Sr?
Calan Sr is a prescription medication containing the active ingredient Verapamil (120mg or 240mg), classified as a calcium channel blocker primarily used for blood pressure management. This extended-release formulation provides 24-hour coverage with once-daily dosing.
Calan Sr is specifically formulated for sustained release, allowing for consistent blood levels of Verapamil throughout the day. This controlled delivery system helps maintain stable blood pressure control and reduces the frequency of dosing compared to immediate-release formulations.
How Calan Sr Works
Calan Sr functions by blocking calcium channels in vascular smooth muscle and cardiac cells. This mechanism results in relaxation of blood vessels and reduced cardiac workload, ultimately leading to lowered blood pressure.
The medication’s extended-release properties ensure a gradual and consistent effect, minimizing peak-to-trough fluctuations in drug concentration. This steady-state delivery is particularly beneficial for maintaining stable blood pressure control throughout the 24-hour dosing interval.

Pharmacy Verification Requirements
Legitimate online pharmacies will always require a valid prescription and provide contact information for registered pharmacists. The Therapeutic Goods Administration (TGA) regulates all medications in Australia.

Potential Side Effects
Like all medications, Calan Sr may cause side effects. Common ones include:

Serious side effects requiring immediate medical attention include slow heartbeat, swelling, or difficulty breathing.
Most side effects are dose-dependent and may diminish as your body adjusts to the medication. However, persistent or severe side effects should be reported to your healthcare provider promptly.
Important Precautions
Before taking Calan Sr, inform your doctor about:
- All medical conditions, especially heart or liver problems
- Other medications you’re taking

Regular monitoring of blood pressure, heart rate, and potential drug interactions is essential during treatment with Calan Sr. Your doctor may recommend periodic blood tests to assess kidney and liver function.

Several alternative blood pressure medications exist, including:

Your doctor will determine the most appropriate treatment based on your individual health profile.
The choice between Calan Sr and alternative medications depends on various factors including comorbidities, potential drug interactions, and individual response to treatment. Combination therapy may sometimes be necessary for optimal blood pressure control.
Cost Considerations
Calan Sr is available through the Pharmaceutical Benefits Scheme (PBS) in Australia for eligible patients. The cost may vary depending on your concession status and the pharmacy you choose.
