Product information

Adalat is a soft capsule treatment used for circulatory conditions such as Raynaud’s phenomenon. It contains an agent called nifedipine, which provides relief from symptoms by allowing blood vessels to relax and facilitating better blood flow. Bayer are the manufacturers of Adalat, which is only available to buy in the UK with a prescription.

  3. Helps blood flow

Raynaud’s phenomenon is a condition whereby blood flow to the fingers and toes becomes inhibited. This leads to temporary discolouration in the extremities, turning them white and then blue, and sometimes other symptoms such as pain, pins and needles and loss of sensation. These will usually pass after a few minutes or hours. It isn’t a serious condition but can be frustrating, due to its effect on the function of the hands.

The condition is divided into two categories: primary and secondary. Primary Raynaud’s is where the condition occurs without an underlying condition, and accounts for the majority of cases. Secondary Raynaud’s may come about as a result of autoimmune illnesses such as rheumatoid arthritis, where the immune system attacks otherwise healthy tissue.

Symptoms of primary Raynaud’s are often triggered by stress or cold weather. In the UK, the NHS estimates that there are around 10 million people living with Raynaud’s, making it an incredibly common illness. Cases where the conditions develops after the age of 30 may require further testing, to determine whether or not an underlying condition is present.

Many cases of Raynaud’s will not necessitate medication. Self-help techniques, such as keeping the body warm, quitting smoking to improve circulation, taking measures to prevent stress and regular exercise can limit the effects. But in those cases where symptoms show no signs of improvement, treatment may be recommended.

In Adalat, the functioning constituent is a drug called nifedipine. This is a calcium-channel blocker, which means that it prevents calcium from acting on muscle walls in blood vessels; a process which can cause them to tense up and constrict. In doing so, nifedipine helps the blood vessels to relax, allowing for better blood flow to the areas of the body being deprived; in the case of Raynaud’s, the fingers and toes.
