More potent and less toxic formulations of epinephrine and methods of medical use
View Patent ↗The present invention provides pharmaceutical formulations of levorotatory-epinephrine, 1-epinephrine, more potent and less toxic than existing pharmaceutical formulations of epinephrine, along with methods of producing and using these pharmaceutical formulations of 1-epinephrine, including providing prefilled syringes of pharmaceutical formulations of 1-epinephrine and methods of using these prefilled syringes by treating patients with continuous intravenous infusion instead of bolus administration.
1. A method of treating a patient having, developing, or recovering from septic shock or anaphylactic shock with a continuous intravenous infusion of l-epinephrine delivered via an at least one intravenous fluid bag with an at least one intravenous line and or an at least one intravenous catheter, said at least one intravenous fluid bag containing up to 1,000 mL of a saline solution or a dextrose and sodium chloride-containing solution, said method comprising the step of injecting an at least one prefilled syringe of a 1 mg injectable liquid pharmaceutical formulation of l-epinephrine into each said at least one intravenous fluid bag or medication port thereof: said at least one prefilled syringe injectable liquid pharmaceutical formulation of l-epinephrine including a tonicity agent and having no more than 12.5% total impurities or no more than 12% d-epinephrine: said method further comprising the diluting of l-epinephrine to a concentration of about 1 microgram per mL in each said at least one said intravenous fluid bag during said continuous intravenous infusion of l-epinephrine; said method optionally comprising protecting said at least one said intravenous fluid bag from light or UV-radiation after said step of injecting said prefilled syringe into said at least one intravenous fluid bag or medication port thereof to prevent l-epinephrine degradation and impurities from forming.
2. A method of treating a patient having, developing, or recovering from septic shock or anaphylactic shock with a continuous intravenous infusion of l-epinephrine delivered via an at least one intravenous fluid bag with an at least one intravenous line and or an at least one intravenous catheter, said at least one intravenous fluid bag containing up to 1,000 mL of a saline solution or a dextrose and sodium chloride-containing solution, said method comprising the step of injecting an at least one prefilled syringe of an at least 1 mL injectable liquid pharmaceutical formulation of l-epinephrine into each said at least one intravenous fluid bag or medication port thereof; said at least one prefilled syringe injectable liquid pharmaceutical formulation of l-epinephrine including a tonicity agent and having no more than 12.5% total impurities or no more than 12% l-epinephrine; said method further comprising the diluting of l-epinephrine to a concentration of about 1 microgram per mL in each said at least one intravenous fluid bag during said continuous intravenous infusion of l-epinephrine; said method optionally comprising protecting said at least one said intravenous fluid bag from light or UV-radiation after said step of injecting said prefilled syringe into said at least one intravenous fluid bag or medication port thereof to prevent l-epinephrine degradation and impurities from forming so that said continuous intravenous infusion of l-epinephrine has a ratio of 1-epinehrine:d-epinephrine greater than 4:1.
3. A method of treating a patient having, developing, or recovering from septic shock or anaphylactic shock with a continuous intravenous infusion of l-epinephrine delivered via an at least one intravenous fluid bag with an at least one intravenous line and or an at least one intravenous catheter, said at least one intravenous fluid bag containing up to 1,000 mL of a saline solution or a dextrose and sodium chloride-containing solution, said method comprising the step of injecting an at least one prefilled syringe of a 1 mL injectable liquid pharmaceutical formulation of l-epinephrine into each said at least one intravenous fluid bag or medication port thereof; thereof: said at least one prefilled syringe injectable liquid pharmaceutical formulation of l-epinephrine including a tonicity agent and having no more than 12.5% total impurities or no more than 12% d-epinephrine; said method further comprising the diluting of l-epinephrine epinephrine to a concentration of about 1 microgram per mL in each said at least one intravenous fluid bag during said continuous intravenous infusion of l-epinephrine; said method optionally comprising protecting said at least one said intravenous fluid bag from light or UV-radiation after said step of injecting said prefilled syringe into said at least one intravenous fluid bag or medication port thereof to prevent 1-epinephrine degradation and impurities from forming so that said continuous intravenous infusion of l-epinephrine having has a ratio of l-epinephrine:d-epinephrine greater than 4:1.
