DELFLEX

The DELFLEX® peritoneal dialysis solutions (low magnesium/low calcium) are sterile, non-pyrogenic formulations of dextrose and electrolytes in water for injection, USP, for use in peritoneal dialysis. These solutions do not contain antimicrobial agents or additional buffers. The stay•safe exchange set utilizes an easy to use dial designed to eliminate the use of clamps and to prevent touch contamination of internal connection components. Composition, calculated osmolarity, pH, and ionic concentrations are shown in Table 2 . Table 2. Composition, calculated osmolarity, pH and ionic concentration Composition/100mL Total Osmolarity (mOsmoL/L) (calc) pH (5.0 - 6.0) Ionic Concentration (mEq/L) Dextrose Hydrous, USP (C 6 H 12 O 6 •H 2 O) Sodium Chloride, USP (NaCl) Sodium Lactate (C 3 H 5 NaO 3 ) Calcium Chloride, USP (CaCl 2 •2H 2 O) Magnesium Chloride, USP (MgCl 2 •6H 2 O) Sodium Calcium Magnesium Chloride Lactate DELFLEX Low Magnesium, Low Calcium with 1.5% Dextrose 1.5 g 538 mg 448 mg 18.4 mg 5.08 mg 344 5.5 132 2.5 0.5 95 40 DELFLEX Low Magnesium, Low Calcium with 2.5% Dextrose 2.5 g 538 mg 448 mg 18.4 mg 5.08 mg 394 5.5 132 2.5 0.5 95 40 DELFLEX Low Magnesium, Low Calcium with 4.25% Dextrose 4.25g 538 mg 448 mg 18.4 mg 5.08 mg 483 5.5 132 2.5 0.5 95 40 Dextrose, USP, is chemically designated D-glucose monohydrate (C 6 H 12 O 6 •H 2 O) a hexose sugar freely soluble in water. The structural formula is shown here: Calcium chloride, USP, is chemically designated calcium chloride dihydrate (CaCl 2 •2H 2 O) white fragments or granules freely soluble in water. Magnesium chloride, USP, is chemically designated magnesium chloride hexahydrate (MgCl 2 •6H 2 O) colorless flakes or crystals very soluble in water. Sodium lactate solution, USP, is chemically designated (CH 3 CH(OH)COONa), a 60% aqueous solution miscible in water. Sodium chloride, USP, is chemically designated (NaCl), a white, crystalline compound freely soluble in water. Water for injection, USP, is chemically designated (H 2 O). Hydrochloric Acid or Sodium Hydroxide may be added for pH adjustment. pH is 5.5 ± 0.5. Exposure to temperatures above 25°C (77°F) during transport and storage will lead to minor losses in moisture content. Higher temperatures lead to greater losses. It is unlikely that these minor losses will lead to clinically significant changes within the expiration period. Since the inner bag is compounded from a specific polyvinyl chloride, water may permeate from the inner bag into the overwrap in quantities insufficient to affect the solution significantly. Solutions in contact with the plastic inner bag can cause certain chemical components of the bag to leach out in very small amounts; however, the safety of the plastic formulation is supported by biological tests for plastic containers. Structural Formula

DELFLEX® is indicated in the treatment of chronic kidney failure in patients being maintained on peritoneal dialysis. For treatment of chronic kidney failure. ( 1 )

( 1 ) For intraperitoneal dialysis only. ( 2 ) 2.1 Basic Dosing Information DELFLEX® is intended for intraperitoneal administration only. Not for intravenous or intra-arterial administration. The mode of therapy, frequency of treatment, formulation, exchange volume, duration of dwell, and length of dialysis should be selected by the physician responsible for the treatment of the individual patient. Utilize the peritoneal dialysis solution with lowest level of osmolarity consistent with the fluid removal requirements for that exchange. Do not store solutions containing additives. 2.2 Administration Instructions Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Do not heat in a microwave oven. Get Ready Clean work surface and gather supplies: Masks (enough for everyone in the room). Warmed DELFLEX peritoneal dialysis solution bag with attached stay•safe exchange set. stay•safe organizer, a stand-alone item provided separately. Povidone iodine prefilled stay•safe cap, a stand-alone item provided separately. IV Pole (optional). Prescribed medication(s), if ordered by your healthcare provider. After removing the overwrap, check your DELFLEX solution bag(s) for strength, clarity, amount, leaks, and expiration date. Do not use DELFLEX solution if leaks are found, the solution bag is damaged, the solution is cloudy or discolored, and/or the product is expired. Color may vary from clear to slightly yellow but does not affect efficacy and may be used. Prepare supplies: Retrieve stay•safe catheter extension set and ensure clamp is closed. Tear the overwrap from the slit edge down the length of the inner bag to open. Wipe away any moisture from the solution bags. Some opacity may be observed in the plastic of the bag and/ or tubing and is due to moisture absorption during the sterilization process. This is normal and does not affect the solution quality or safety. The opacity will diminish gradually. Visually check that the solution bag tubing is free from kinks. If kinks are present, straighten tubing to allow the solution to flow freely. Note: Retain DELFLEX peritoneal dialysis bag sample for manufacturer evaluation and notify your healthcare provider if any of the above defects are found. Put on mask. Wash your hands per facility protocol. Position the stay•safe organizer at the edge of your clean work surface or with the stay•safe holder on the IV pole. Remove color-coded cover: Turn the blue dial as directed by the arrow in the color—coded cover. Remove the colored—coded cover from the stay•safe DISC. The blue dial will be in Position 1 ( ) DRAIN. Prepare organizer and solution bag: Place the stay•safe DISC and tubing into the organizer and tubing channels on the organizer. If you will be adding medication(s): Clean hands (as per facility's protocol). Clean the medication port as instructed by your healthcare provider. Add the medicine(s). Turn the bag upside down several times to mix the medicine(s). Hang the DELFLEX peritoneal dialysis solution bag on the IV pole and place the drain bag with the clear side up on the floor. Break cone of the administration port. Remove new stay•safe cap from its package and place stay•safe cap into the left notch of the organizer. Place stay•safe catheter extension set into organizer. Clean hands (as per facility's protocol). Place stay•safe catheter extension set into the right notch of the organizer. Ensure clamp of stay•safe catheter extension set is closed. Remove protective cap from stay•safe DISC and set aside. Connect stay•safe catheter extension set to the stay•safe DISC. Unscrew stay•safe catheter extension set from its cap. Immediately connect the stay•safe catheter extension set to the stay•safe DISC. Open the white clamp of stay•safe catheter extension set and start DRAIN. Place discarded protective cap from stay•safe DISC onto the used stay•safe cap in the stay•safe organizer and discard. When DRAIN is complete: Turn blue dial to Position 2( ), FLUSH for about 5 seconds. Make sure the line between solution bag and stay•safe DISC is fully primed. When FLUSH is complete: Turn blue dial to Position 3( ), FILL to begin the fill of solution to your abdomen. Flow rate can be adjusted from slow( ) to moderate ( ) to fast ( ). When FILL is complete: Turn blue dial as far as possible in Position 4 ( ), PIN/CLOSE until you feel and/or hear a “click”. The stay•safe PIN located in the stay•safe DISC will automatically be released into the end of the stay•safe catheter extension set. When PIN/CLOSE is complete: Close the clamp of the stay•safe catheter extension set. Using aseptic technique, mask then wash hands as instructed by your healcare provider. Unscrew protective cover from the new stay•safe cap and set aside. Disconnect from stay•safe DISC: Unscrew the stay•safe catheter extension set from the stay•safe DISC. Immediately attach the stay•safe catheter extension set with a PIN to the new stay•safe cap. Remove capped catheter extension set from organizer and secure to your abdomen. Complete treatment: Place protective cover from the new stay•safe cap on the stay•safe DISC connector to prevent drips. Weigh drain bag (as per facility's protocol). Record exchange results on treatment log. If an effluent sample is required: Use aseptic technique and facility protocols throughout collection. Scrub the drain bag's sample port hub with friction and an Isopropyl Alcohol 70% swab/prep pad for 15 seconds, and allow to dry for 30 seconds more. Withdraw the effluent sample directly from the sample port hub with a needle and syringe. Discard the used tubing and solution (as per facility's protocol). Throw away the fluid and used exchange set as instructed by your healthcare provider. In case of cloudiness, save the fluid and the used exchange set and immediately contact your healthcare provider.
