Contraindication ::

Patients predisposed to active bleeding including thrombocytopenia, peptic ulcer disease, cerebrovascular disorders, haemorrhagic blood disorders, bacterial endocarditis, severe hypertension, oesophageal varices. Recent surgery at sites where haemorrhage would be an especial risk. Severe renal and hepatic impairment. Cerebral or subarachnoid haemorrhage, abdominal or thoracic bleeding into closed space, severe traumatic bleed, hepatic, renal, splenic or arterial injury, severe haemostatic defect, arterial thrombosis with heparin-associated thrombocytopenia. IM admin.

Drug Precautions ::

Monitor platelet counts. Discontinue treatment if thrombocytopenia occurs. Hypersensitivity, elderly, pregnancy.

Drug Side Effects ::

Slight fever, headache, chills, nausea, vomiting, constipation, epistaxis, bruising, slight haematuria, skin necrosis (SC inj), osteoporosis, alopecia. Hypersensitivity reactions include urticaria, conjunctivitis, rhinitis, asthma, angioedema and anaphylactic shock. Priapism. Potentially Fatal: Heparin-induced thrombocytopenia with or without thrombosis; bleeding.

Pregnancy category ::

3

Drug Mode of Action ::  

Heparin increases the inhibitory action of antithrombin III (AT III) on clotting factors XIIa, XIa, IXa, Xa and thrombin. This inhibits the conversion of prothrombin to thrombin and fibrinogen to fibrin. It also inhibits platelet function. It may reduce the activity of ATIII at very high doses.

Drug Interactions ::

Enhanced anticoagulant effect w/ other drugs affecting platelet function or the coagulation system (e.g. platelet aggregation inhibitors, thrombolytic agents, salicylates, NSAIDs, vit K antagonists, dextrans, activated protein C). Decreased anticoagulant effect w/ gyceryl trinitrate infusion. Increased risk of hyperkalaemia w/ ACE inhibitors or angiotensin II antagonists.
