Pharmaceutical composition for the parenteral administration of ultrashort-effective β-adrenoreceptor antagonists
The present invention relates to a pharmaceutical composition in the form of a storage-stable solution for the parenteral administration of ultrashort-effective β-adrenoreceptor antagonists, comprising a) an ultrashort-effective β-adrenoreceptor antagonist and/or a pharmaceutically acceptable salt thereof, b) water, and c) a cyclodextrin and/or a functional cyclodextrin derivative. The composition according to the invention has high stability, even without the presence of additional adjuvants.
1. A pharmaceutical composition comprising:
a) landiolol or a pharmaceutically acceptable salt thereof at a concentration from 0.005 to 2% (w/v);
b) water; and
c) 2-hydroxypropyl-β-cyclodextrin at a concentration from 0.1 to 20% (w/v).
2. The pharmaceutical composition of claim 1 , wherein the pH value of the composition is 3 to 7.5.
3. The pharmaceutical composition of claim 2 , wherein the pH value of the composition is 5 to 7.
4. The pharmaceutical composition of claim 1 , wherein the concentration of 2-hydroxypropyl-β-cyclodextrin is 0.1% to 15% (w/v).
5. The pharmaceutical composition of claim 4 , wherein, the concentration of 2-hydroxypropyl-β-cyclodextrin is 0.25% to 7% (w/v).
6. The pharmaceutical composition of claim 5 , wherein the concentration of 2-hydroxypropyl-β-cyclodextrin is 0.5% to 4%.
7. The pharmaceutical composition of claim 1 , wherein the concentration of the landiolol or pharmaceutically acceptable salt thereof is 0.01% to 1.0% (w/v).
8. The pharmaceutical composition of claim 1 , wherein the composition has an osmolarity of 270 mosmol/l to 310 mosmol/l.
9. The pharmaceutical composition of claim 8 , wherein the composition has an osmolarity of 280 mosmol/l to 300 mosmol/l.
10. The pharmaceutical composition of claim 1 , wherein the composition is present in the form of a sales unit selected from the group consisting of:
1 ml solution containing 5-20 mg landiolol or a salt thereof,
2 ml solution containing 5-40 mg landiolol or a salt thereof.
11. A method of reducing heart beat frequency in a patient comprising administering a composition of claim 1 to a patient, whereby the heart beat frequency in the patient is reduced.
12. The method of claim 11 , wherein the patient has atrial fibrillation, atrial flutter, sinus tachycardia, atrioventricular tachycardia, AV node tachycardia, supraventricular tachycardia, ventricular arrhythmias, perioperative ischaemia, unstable angina pectoris, or acute myocardial infarction.
