2.5 Preparation of the
Oral Suspension Prepare the suspension at time of dispensing as follows: Tap bottle until all powder flows freely. Measure the total amount of water (see Table 2) to be added in two parts. Add approximately 2/3 of the total amount of water for reconstitution, replace cap and shake vigorously to suspend powder. Add remainder of the water (that had been measured), replace cap and again shake vigorously.
Table 2: Volume of Water for Reconstituting Amoxicillin and Clavulanate Potassium for Oral Suspension, 600 mg/42.9 mg per 5 mL Bottle Size Amount of Water Required for Reconstitution 75 mL 68 mL 125 mL 108 mL 200 mL 170 mL Each 5 mL will contain 600 mg of amoxicillin as the trihydrate, and 42.9 mg of clavulanic acid as the potassium salt. Shake oral suspension well before each use. Suspension must be refrigerated. Discard after 10 days. Suspension is off-white at time of reconstitution; some color change is normal during the dosing period.
Flavoring Information: For patients who wish to alter the taste of amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL, immediately after reconstitution, 1 drop of FLAVORx ® (apple, banana cream, bubble gum, cherry, or watermelon flavor) may be added for every 5 mL of amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL. The resulting suspension is stable for 10 days under refrigeration. Stability of amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL when mixed with other flavors other than the 5 flavors listed above has not been evaluated.
2.6 Switching between
Dosage Forms and between Strengths Amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL does not contain the same amount of clavulanic acid (as the potassium salt) as any of the other suspensions of amoxicillin and clavulanate potassium. Amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL contains 42.9 mg of clavulanic acid per 5 mL, whereas the amoxicillin and clavulanate potassium, 200 mg/28.5 mg per 5 mL suspension contains 28.5 mg of clavulanic acid per 5 mL and the 400 mg/57 mg per 5 mL suspension contains 57 mg of clavulanic acid per 5 mL. Therefore, the amoxicillin and clavulanate potassium 200 mg/28.5 mg per 5 mL and 400 mg/57 mg per 5 mL suspensions should not be substituted for amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL as they are not interchangeable.
