Tiadylt ER is a medication used to treat high blood pressure and chronic stable angina, which is chest pain caused by reduced blood flow to the heart. It works by relaxing the blood vessels, making it easier for the heart to pump blood and reducing the heart's workload. You typically take it as a capsule once a day, starting with a dose of 120 to 240 mg, which can be increased up to a maximum of 540 mg based on your needs. It's important to know that this medication should not be taken if you have certain heart conditions, such as sick sinus syndrome or severe low blood pressure. Additionally, if you're taking beta-blockers, you may need to adjust the doses of both medications to avoid potential heart rhythm issues.
