Treat severe muscle rigidity: 1 mg/kg rapid IV push, may repeat q1-3 minutes until muscle relaxation or total dose of 10 mg/kg. When patient can tolerate po may substitute 1-2 mg/kg orally 4 times daily. If refractory (NMS) consider adding bromocriptine 5 mg tid initially-if response is inadequate, increase dose rapidly to max of 10-20 mg orally every 6 hours.

Usual Diluents
NS
Standard Dilutions   [Amount of drug]  [Infusion volume]  [Infusion rate]
[(4 mg/kg) /50 ml] [30 min]
Stability/Misc.

DOSAGE AND ADMINISTRATION
Complicated Skin and Skin Structure Infections: CUBICIN 4 mg/kg should be administered over a 30-minute period by IV infusion in 0.9% NACL q 24 hours x 7-14 days. Doses of CUBICIN higher than 4 mg/kg/day have not been studied in Phase 3 controlled clinical trials. In Phase 1 and 2 clinical studies, CPK elevations appeared to be more frequent when daptomycin was dosed more frequently than once daily. Therefore, CUBICIN should not be dosed more frequently than once a day.

Renal Dosing:
CrCl >= 30 ml/min:  4 mg/kg q24h
CrCl < 30 ml/min: 4 mg/kg q48h (Including patients receiving hemodialysis or CAPD.)

PREPARATION: CUBICIN 250 mg vial:  reconstitute with 5 mL of 0.9% NACL injection.  500 mg vial should be reconstituted with 10 mL of 0.9% NACL injection. Reconstituted CUBICIN should be further diluted with 0.9% sodium chloride injection (50ml) and infused over a period of 30 minutes.

SUPPLIED: CUBICIN is supplied in single-use vials containing either 250 or 500 mg daptomycin as a sterile, lyophilized powder.  

STABILITY: Stability studies have shown that the reconstituted solution is stable in the vial for 12 hours at
room temperature or up to 48 hours if stored under refrigeration at 2 to 8°C (36 to 46°F). The diluted solution is stable in
the infusion bag for 12 hours at room temperature or 48 hours if stored under refrigeration. The combined time (vial and
infusion bag) at room temperature should not exceed 12 hours; the combined time (vial and infusion bag) under refrigeration
should not exceed 48 hours.

Compatible Intravenous Solutions: CUBICIN is compatible with 0.9% sodium chloride injection and lactated Ringer’s injection. CUBICIN is not compatible with dextrose-containing diluents.

STORAGE: Store original packages at refrigerated temperatures 2 to 8°C (36 to 46°F); avoid excessive heat.

DIGOXIN (LANOXIN) All doses/ 50 ml 15 min NS / D5W
Stability/Misc.







Immediate use is recommended. Minimum of a 4-fold dilution. 
Loading dose:
CHF: 8-12 mcg/kg in divided doses (q4-8h) over 12 to 24 hours. [Normally, give 50% of the total digitalizing dose in the initial dose, then give 25% of the total dose in each of the two subsequent doses at 8 to 12 hr intervals--Obtain EKG 6 hours after each dose to assess potential toxicity (AV block, sinus bradycardia, atrial or nodal ectopic beats, ventricular arrhythmias); Other: vision changes, confusion.]   
If pt has renal insufficiency give 6 to 10 mcg/kg IBW. 
A-fib:
10 to 15 mcg/kg IBW given as above. (If given IVPush - administer over at least 5 minutes).
  Maintenance dose: Digoxin clearance= [CRCL + 40] x 1.44 (add 20 instead of 40 if pt has CHF).    Predicted Css= (Dose) (0.65 to 0.8)/ Digoxin clearance. Alternatively, maintenance dose= Loading dose x [0.14 x crcl / 500 ]    Avoid IM injections-can lead to severe pain (If it must be given by this route, give deep IM followed by massage).
  Monitoring: Obtain blood samples at least 4 hours after IV dose and 6-8hours after oral dose. Serum levels: 0.5 to 2.5 ng/ml    Onset/peak: IV: 5-30min/ 1-4hours         Oral: 1-2hours/ 2-8 hours. Time to steady state: 5-7 days (average) ESRD: 15-20 days. Half-life: 38-48 hours. (anephric: 4-6 days). Conversion from oral to IV: Decrease IV dose by 20 to 25%. When the maintenance dose is given IV, the onset and peak will occur earlier, however the duration of action is the same. Patients' on the "floors" may receive once daily IV maintenance doses, however, IV loading regimens (multiple doses) are restricted to patients on a monitor- ICU's. [Oral bioavailability (tablets): 70 to 80%].

Stability/Misc.

 

 




Indications: Treatment of patients with acute coronary syndrome (unstable angina or Non-Q wave MI).  Administration: Bolus: withdraw dose from 10ml vial and give by ivpush over 1-2 minutes. Continuous infusion: administer calculated rate directly from 100ml vial. [Supplied: 0.75 mg/ml (100ml) vial; 20 mg/10 ml vial. (REF) ] Properties: Onset: within 1 hr. //     T1/2: 2.5 hours    // Platelet function restored in @ 4hours after discontinuation. 

Acute Coronary Syndrome: The recommended adult dosage of eptifibatide in patients with acute coronary syndrome and normal renal function is an intravenous bolus of 180 µg/kg (maximum: 22.6 mg) over 1-2 minutes as soon as possible following diagnosis, followed by a continuous infusion of 2.0 µg/kg/min (maximum: 15 mg/hour) until hospital discharge or initiation of CABG surgery, up to 72 hours. If a patient is to undergo a percutaneous coronary intervention (PCI) while receiving eptifibatide, the infusion should be continued up to hospital discharge, or for up to 18-24 hours after the procedure, whichever comes first, allowing for up to 96 hours of therapy. Concurrent aspirin (160-325 mg initially and daily thereafter) and heparin therapy (target aPTT 50-70 seconds) are recommended.

Dosing adjustment in renal impairment:  Patients with CRCL less than 50 ml/min:  The recommended adult dosage of eptifibatide in patients with acute coronary syndrome with an estimated CRCL <50 ml/min (using the Cockcroft-Gault equation)  is an IV bolus of 180 µg/kg (maximum: 22.6 mg) as soon as possible following diagnosis, immediately followed by a continuous infusion of 1.0 µg/kg/min (maximum: 7.5 mg/hour).

Percutaneous Coronary Intervention (PCI):  The recommended adult dosage of eptifibatide in patients with normal renal function is an intravenous bolus of 180 µg/kg (maximum: 22.6 mg) over 1-2 minutes administered immediately before the initiation of PCI followed by a continuous infusion of 2.0 µg/kg/min (maximum: 15 mg/hour) and a second 180 µg/kg bolus (maximum: 22.6 mg) 10 minutes after the first bolus. Infusion should be continued until hospital discharge, or for up to 18 to 24 hours, whichever comes first. A minimum of 12 hours of infusion is recommended. Concurrent aspirin (160-325 mg 1-24 hours before PCI and daily thereafter) and heparin therapy (ACT 200-300 seconds during PCI) are recommended. Heparin infusion after PCI is discouraged.

Dosing adjustment in renal impairment:   Patients with CRCL less  than 50 mL/min:  The recommended adult dose of eptifibatide in patients with an estimated CRCL < 50 ml/min (using the Cockcroft-Gault equation) is an IV bolus of 180 µg/kg (maximum: 22.6 mg) administered immediately before the initiation of the procedure, immediately followed by a continuous infusion of 1.0 µg/kg/min (maximum: 7.5 mg/hour) and a second 180 µg/kg bolus (maximum: 22.6 mg)  administered 10 minutes after the first.  In patients who undergo coronary artery bypass graft surgery, eptifibatide infusion should be discontinued prior to surgery.
