 Ischemic stroke 

  • Thombolysis- clot bursting medication 
  • Antiplatelets- this makes blood cells less sticky ( reducing chances of clots forming again)
  • Anticoagulants - also helps prevent the forming of clots in the future
  • ACE Inhibitors 
  • Calcium channel blockers 
  • Beta blockers 
  • Alpha Blockers


these are used to treat hight blood pressure (Antihypersentitves )

  • Statins -to lower blood cholestorl levels 

Haemorrhagic strokes 

Surgery- Crainiotomy
