Adalat Chrono (Nifedipine) is from a group of drugs called calcium channel blockers and is used to treat hypertension (commonly known as high blood pressure) and angina (chest pain). This is an oral tablet medication that is usually round and red/pink in color. This medication is not available in generic form but is available as Adalat CC in 30MG and 60MG strengths. It is also available in extended release, the XL (extended release) will typically last longer due to the formation of the pill.

This medication works because the nifedipine in the tablet relaxes the muscles of your heart and your blood vessels. It does this by blocking the calcium from going into the muscles. In order for muscles to contract, they need calcium. With no calcium, they cannot contract which results in relaxed muscles.
