What’s Heparin?
Heparin is a direct anticoagulant. It belongs to thrombin inhibitors and is a significant software for the remedy of arterial and venous thromboses of various etiology.
Heparin is a combination of excessive molecular weight sulfated mucopolysaccharides.
It’s most frequently used subcutaneously or intravenously. After oral consumption, it’s inactive and shouldn’t be absorbed.
Due to its massive molecule, the heparin doesn’t cross the placental barrier and shouldn’t be excreted in breast milk. It’s efficient and protected to be used throughout being pregnant and lactation.
Heparin is biotransformed and disposed of within the liver and is eradicated from the physique by the kidneys.
Heparin is used for remedy and prophylaxis of:
- deep vein thrombosis,
- pulmonary thromboembolism,
- throughout surgical interventions in threat sufferers,
- acute myocardial infarction,
- upkeep remedy following fibrinolytic remedy with streptokinase, and so forth.
One of many critical side effects of heparin is the event of thrombocytopenia.
Throughout long-term heparin remedy, the next unwanted side effects might be anticipated:
- bleeding,
- hair loss and alopecia,
- osteoporosis and spontaneous fractures,
- hypersensitivity reactions occurring most frequently with urticaria, fever, redness.
Low doses pose a threat of activation of thrombosis processes, whereas overdose is prone to develop hemorrhages.
What’s Warfarin?
Warfarin (4-hydroxycoumarins) is an oblique anticoagulant. After oral consumption, warfarin is quickly and fully absorbed from the gastrointestinal tract.
Warfarin is used for remedy and prophylaxis of:
- deep vein thrombosis,
- pulmonary embolism,
- valvular heart disease,
- atrial fibrillation, and so forth.
Warfarin is metabolized within the liver and has a protracted plasma half-life, which predisposes to cumulation and improvement of poisonous reactions.
The principle impact of warfarin is inhibition in blood clotting.
It falls into Danger class X, which signifies that the danger of its use significantly exceeds the anticipated profit.
It ejects with the breast milk and passes by means of the placental barrier.
When utilizing this preparation throughout being pregnant a attribute dysmorphism develops. Quite a lot of organs and programs are affected, primarily the central nervous system, the locomotory system, the cardiovascular system, the eyes.
The medical impact happens after 12 to 72 hours.
The principle indications for using warfarin embody prophylaxis of venous thrombosis and pulmonary thromboembolism. Additionally it is used after a myocardial infarction, to stop a recurrence of the situation, and after heparin remedy.
Throughout remedy, periodic monitoring of sure parameters is required as a result of small distinction between the maximal therapeutic and minimal poisonous dose. There’s a vital threat of overdosage and improvement of intoxication.
The low dose may cause thrombosis, whereas overdose causes hemorrhages. A selected antidote and antagonist of warfarin is vitamin Ok.
Throughout long-term warfarin remedy, the next unwanted side effects might be anticipated:
- bleeding,
- hair loss and alopecia,
- nausea, stomach ache,
- fatigue, headache, dizziness,
- issues from the respiratory system, trachea or tracheal-bronchial calcification (very uncommon),
- pores and skin rash, pruritus, dermatitis, vasculitis.
With extended consumption, the preparation is hepatotoxic and results in impairment of liver operate.
The impact of warfarin is enhanced by cimetidine, chloramphenicol, metronidazole, some broad-spectrum antibiotics. A lower within the impact is brought on by barbiturates, estrogens, vitamin Ok, cholestyramine.
