Hi! I read carefully your query. I can give you some information for each one of this drugs. Treating patients diagnosed as CVA is very complex and explain the number of drugs given to the patient. Nootropil (Piracetam) is useful as a long-term treatment for clotting, coagulation, and vasospastic disorders such as Raynaud s phenomenon and deep-vein thrombosis. It is an extremely safe anti-thrombotic agent that operates through the novel mechanism of inhibiting platelet aggregation and enhancing blood-cell deformability. Midazolam belongs to a class of medications called benzodiazepines, which produce a calming effect on the brain and nerves (central nervous system). It is thought to work by increasing the effect of a certain natural chemical (GABA) in the brain. Ecosprin belongs to a class of drugs which is known as nonsteroidal anti-inflammatory drugs (NSAIDs). Ecosprin is used long-term, at low doses, to help prevent heart attacks, strokes, and blood clot formation in people at high risk for developing blood clots All NSAIDs work by reducing the levels of prostaglandins, chemicals that are released when there is inflammation and that cause pain and fever. Ecosprin inhibits the function of platelets in a manner that is different from other NSAIDs, and its antithrombotic effects last longer than other NSAIDs. This is why Ecosprinis is used for preventing heart attacks and strokes. Mannitol is an osmotic diuretic that can be used to treat cerebral edema.Because when a cerebrovascular accident, also known as a stroke,has happened the damaged zone in the brain is surrounded by an edematous zone.Mannitol acts by reducing this zone. Amlodipine is in a class of medications called calcium channel blockers. It is used alone or in combination with other medications to treat high blood pressure and chest pain (angina).In this case the cause of CVA might have been high blood pressure and for this reason is given Amlodipine,to keep BP under control. Hope it answered your query. Take care. Dr.Rovena
