4.2
Posology and method of administration
Dosage:
Dosages are determined in accordance with the respective indication.
Peripheral arterial thrombosis
Systemic lysis:
For the treatment of arterial occlusion, the recommended initial dose of urokinase is
250,000 ‑ 600,000 IU given intravenously over 10 ‑ 20 minutes, with 80,000 ‑ 150,000
IU urokinase/h as a maintenance dose.
Simultaneous administration of heparin is generally required to ensure adequate
protection against recurrent thrombosis. The start time and duration of the heparin
infusion will depend on the aPTT, which should be extended to 1.5 to 2.5 times the
normal aPTT. A dose of 500 ‑ 1,000 IU of unfractionated heparin/h i.v. is generally
sufficient.
Local lysis:
The thrombus is first infiltrated with urokinase solution. The dose should not exceed
100,000 ‑ 120,000 IU/hour for a patient weighing 70 kg. Local lysis is performed until
a successful outcome has been achieved (up to a maximum of 48 hours).
Deep vein thrombosis
The initial dose of urokinase is 250,000 ‑ 600,000 IU urokinase given intravenously
over 10 ‑ 20 minutes. The maintenance dose is 40,000 ‑ 100,000 IU/h.
Simultaneous administration of heparin is generally required to ensure adequate
protection against recurrent thrombosis. The start time and duration of the heparin
infusion will depend on the aPTT, which should be extended to 1.5 to 2.5 times the
normal aPTT. A dose of 500 ‑ 1,000 IU of unfractionated heparin/h i.v. is generally
sufficient.
Pulmonary embolism
The initial dose is 2,000 or 4,400 IU of urokinase/kg body weight given intravenously
over 10 ‑ 20 minutes. The maintenance dose is 2,000 IU of urokinase/kg body
weight/h over 24 hours with simultaneous administration of heparin, or 4,400 IU of
urokinase/kg of body weight/h over 12 hours without heparin. The start time and
duration of the heparin infusion will depend on the aPTT.
Subsequent administration of heparin is generally required to ensure adequate
protection against recurrent thrombosis. The start and duration of the heparin infusion
will depend on the aPTT, which should be extended to 1.5 to 2.5 times the normal
aPTT. A dose of 500 ‑ 1,000 IU of unfractionated heparin/h i.v. is generally sufficient.
Thrombosed arteriovenous shunt
Urokinase solution with a concentration of 5,000 ‑ 25,000 IU/ml is instilled into both
tube sets in the shunt.
Method of administration
For injection, infusion and local instillation after dissolution as instructed.
The contents of one vial of Urokinase medac 10,000 I.U. are dissolved in 2 ml of
water for injections.
The contents of one vial of Urokinase medac 50,000 I.U. are dissolved in 2 ml of
water for injections.
The contents of one vial of Urokinase medac 100,000 I.U. are dissolved in 2 ml of
water for injections.
The contents of one vial of Urokinase medac 250,000 I.U. are dissolved in 5 ml of
water for injections.
The contents of one vial of Urokinase medac 500,000 I.U. are dissolved in 10 ml of
water for injections.
For drip infusions, the contents of one vial can be dissolved in water for injections
and then diluted to a final volume of 50 ml in e.g. a 5% or 10% glucose solution or
physiological saline.
Duration of administration:
The duration of administration depends on the respective indication.
Peripheral arterial thrombosis
The duration of treatment with urokinase depends on the clinical findings and on the
results of diagnostic procedures. The average duration of treatment is 4 ‑ 5 days.
Deep vein thrombosis
The duration of treatment, which depends on an objectively confirmed successful
therapeutic outcome, is generally 7 ‑ 14 days.
Pulmonary embolism
The treatment duration is 24 hours when following the low‑dose urokinase/heparin
dosing regimen and 12 hours when following the high‑dose urokinase regimen.
Thrombosed arteriovenous shunt
The application of urokinase can if necessary be repeated every 30 minutes.
However, the duration of treatment should not exceed 2 hours.
4.3

4.4
Special warnings and special precautions for use
Urokinase may only be used with extreme caution:
in cerebrovascular diseases other than those mentioned in section 4.3 or
where there is a known history of cerebrovascular events in the more distant
past,
in arterial hypertension,
in the event of thrombi in the left heart (e.g. accompanying mitral valve stenosis
with atrial fibrillation),
in the event of septic thrombophlebitis or an infected arteriovenous fistula with
thrombotic occlusion,
in any circumstances in which a possible source of bleeding is difficult to
access,
in the event of a reduced platelet count and/or changes in laboratory parameters
indicative of impaired haemostasis (such as prolonged thrombin time, aPTT,
Quick etc.).
Intramuscular injections and the use of rigid catheters are to be avoided during
treatment with urokinase.
After cardiac massage administered during cardiopulmonary resuscitation there is an
increased risk of complications associated with bleeding.
If bleeding occurs, the procedures described in section 4.9 should be followed.
When using medicinal products made from human proteins, the transmission of
infectious diseases ‑ including those of a previously unknown nature ‑ cannot be
ruled out entirely. However, due to the required inactivation procedure (heating in
solution for 10 hours at + 60 °C), this risk is extremely small.
Patients on a high dosage are monitored, as under any fibrinolytic therapy, by
determining their fibrinogen and aPTT, and thrombin time if applicable.
By contrast, at dosages below 40,000 IU/hour, there is generally hardly any change
in laboratory parameters; fibrinolytic activity is shown in this case by a reduced
euglobulin lysis time and an increase in fibrin degradation products.
There is an increased risk of intracranial haemorrhage in elderly patients. Therefore,
the risk‑benefit ratio should be analysed with extreme care in these patients.
The experience in children is limited.
A dose reduction may be required in patients with impaired renal and/or hepatic
function. In these cases, the fibrinogen level should not fall below 100 mg/dl.
4.5
Interaction with other medicinal products and other forms of
interaction
There is an increased risk of bleeding from the prior or concomitant administration of
any of the following:
anticoagulants such as heparin or coumarin derivatives,
drugs that affect platelet formation or function, such as:
acetylsalicylic acid,
allopurinol,
clofibric acid derivatives,
clopidogrel,
indomethazine,
dipyridamole,
phenylbutazone,
ticlopidine,
tetracycline,
valproic acid,
thiouracils,
sulfonamides,
cytostatic agents,
dextrans,
non‑steroidal anti‑inflammatory drugs.
The following substances inhibit the fibrinolytic action of urokinase:
antifibrinolytics such as aprotinin, p‑aminobenzoic acid, epsilon aminocaproic
acid and tranexamic acid.
4.6
Pregnancy and lactation
Pregnancy:
To date, there are no adequate data for use of urokinase during pregnancy. Low‑
molecular urokinase fragments and active plasmin cross the placenta. Although
animal studies showed no evidence of reproductive toxicity, maternal exposure was
inadequate (see section 5.3). Throughout pregnancy, because of the risk to the foetus,
urokinase must only be administered if vitally indicated and following particularly
careful consideration of the risk. The occurrence of bleeding and premature labour, as
well as passive immunisation of the foetus by maternal antibodies against urokinase,
cannot be ruled out.
The use of urokinase is absolutely contraindicated in the first four weeks after
giving birth, in the event of abortion or imminent abortion, or if placenta praevia is
suspected.
Lactation:
There are no data available regarding the passage of urokinase into breast milk.
Urokinase should only be administered during lactation if it is absolutely necessary
for the health of the mother. In this case, breast feeding should be interrupted for the
duration of the therapy.
4.7

4.9
Overdose
In the event of bleeding that can be controlled by compression, the therapy can be
continued under close monitoring.
In the event of complications due to bleeding which cannot be controlled using the
above measures and which require treatment, the urokinase therapy must be stopped
and aprotinin or another antifibrinolytic drug must be administered if necessary. The
dose of aprotinin is initially 500,000 – 1,000,000 KIU/h i.v., then 50,000 – 100,000
KIU/h until haemostasis is achieved. (Be aware of the possibility of anaphylaxis!)
In the case of severe and life‑threatening haemorrhage due to severe hyperfibrinolysis,
the urokinase treatment must be discontinued immediately. Antifibrinolytic therapy
should
complemented
with
substitution
fibrinogen
concentrate
appropriate blood products. This treatment should be given in consultation with a
specialist in transfusion medicine experienced in haemostaseology.

Pharmacological properties
5.1
Pharmacodynamic properties
Pharmacotherapeutic group: fibrinolytic
ATC code: B01AD04
Urokinase is a serine protease that occurs in different molecular forms. A distinction is
made between a high‑molecular weight and a low‑molecular weight form.
The mean molecular weight of the high‑molecular weight form (HUK) is about 54,000
Daltons, that of the low molecular weight form (LUK) is given as approximately
33,000 Daltons.
The enzyme is formed primarily in the kidneys and secreted into the urine. Urokinase
can be isolated from human urine or from the supernatants of human kidney cell
cultures or produced in recombinant form.
The activity is determined in international units based on the standard preparations
established by the WHO.
These units are based on the fibrinolytic activity of urokinase.
Prourokinase (SCUPA) is the zymogen of urokinase. It is converted into urokinase
(HUK) by trypsin‑type serine proteases such as plasmin or thrombin.
Urokinase
specific
affinity
plasminogen
molecule
converts
plasminogen directly into plasmin by hydrolysis of the arginine‑valine bond.
Fibrinous thrombi can be broken up by the fibrinolytic effect of the protease plasmin.
The plasmin activity triggered by urokinase results in a dose‑dependent drop in the
level of plasminogen and fibrinogen and to the increased incidence of fibrin and
fibrinogen degradation products (FDP), which in addition to their direct anticoagulant
effect potentiate the effect of heparin. Urokinase remains active for up to 12 ‑ 24
hours after the end of the infusion.
The conversion by urokinase of plasminogen into plasmin can be competitively
inhibited by epsilon aminocaproic acid, tranexamic acid and p‑aminobenzoic acid.
However, these fibrinolysis inhibitors do not cancel out the anticoagulant effect of
circulating fibrinogen/fibrin degradation products.
Aprotinin (like α
antiplasmin in the plasma) has a direct inhibitory effect on plasmin.
Urokinase activity can be inhibited to varying degrees in individual cases by urokinase‑
inhibiting plasma proteins (e.g. in uraemia).
5.2
Pharmacokinetic properties
Urokinase must be administered parenterally.
Urokinase is removed rapidly from circulating blood after intravenous administration.
The elimination half life of urokinase is approximately 10 – 20 minutes.
Inactivation (enzymatic degradation) probably occurs primarily in the liver. The
inactive degradation products are excreted via the bile and primarily via the kidneys.
The clinical efficacy half life depends on the duration of efficacy of the activated
plasmin and is therefore longer.
5.3
Preclinical safety data
Chronic toxicity studies in various animal species and studies investigating mutagenic
potential do not indicate any particular risks for humans. There are no long‑term
studies investigating carcinogenic potential.
Embryotoxicity studies in rats, mice and rabbits at doses corresponding at most to 1.4
times the human dose (based on a therapeutic dose in humans of 105,600 IU/kg/day)
gave no indication of any teratogenic potential. Neither were the fertility of rats and
the perinatal and postnatal development of their offspring impaired at these doses.
