Generic Name: Aspirin; Dipyridamole
Product Name: Asasantin SR
Asasantin SR is used to reduce the risk of strokes and transient ischaemic attacks (TIAs) in at-risk patients. Ischaemic stroke refers to the disruption of blood supply to the brain secondary to blood clots within the vessels. This can lead to serious disabilities including paralysis and speech and language difficulties. TIA is sometimes called a mini-stroke as these symptoms last less than 24 hours however patients are at increased risk of stroke in the future.
Asasantin SR contains a combination of aspirin and dipyridamole. These drugs work on the platelets circulating in the blood, and help prevent them from clumping and sticking together. This reduces the risk of the formation of blood clots that can lead to a stroke. The effects of the drugs are additive.
- Asasantin comes as one type of formulation which is a red and ivory coloured capsule that contains two drugs- 200mg of dipyridamole and 25mg of aspirin. Each pack contains 60 capsules.
- The recommended dose is one capsule twice a day, usually one in the morning and one in the evening with meals.
- The capsules should be swallowed whole without being chewed.
Common side effects
Like all medications, Asasantin can cause side effects including:
- Headache which can be severe
- Nausea and vomiting
- Myalgia (muscle aches)
- Hypotension (low blood pressure)
- Hot flushes
- Tachycardia (fast heart beat).
Uncommon side effects
- Allergic reactions causing swelling of the face, lips and tongue, difficulty breathing and skin changes.
- Worsening of symptoms of coronary heart disease.
- Haemolysis (breakdown of red blood cells) may be caused by aspirin in patients with glucose-6-phosphate dehydrogenase deficiency.
- Thrombocytopenia (low blood platelets which are normally important in stopping bleeding from cuts and other trauma).
The above lists are not necessarily exhaustive and if you experience any worrying symptoms do not hesitate to see your doctor. In most patients however, Asasantin will be well tolerated and side effects will be mild and gradually disappear as you continue to take your medication.
