Preparation 2: Lactose capsules, hand filled

#00 Hand-Filled Capsules: Using techniques learned in previous laboratories, weigh out 8.4 g of lactose and 100 mg of dye. Place the powder on an ointment slab. Using two metal spatulas, blend the powder and dye using geometric dilution. Compact the powder into a block about one-third the height of a #00 capsule. Remove the caps from ten of the #00 gelatin capsules and set aside. Using your dominant hand, hold the body of one of the open capsules between your thumb, index, and middle finger. Make sure the open end of the capsule is pointing down. Repeatedly punch the open end of the capsule into the lactose powder until the body is full. Place a cap on the filled capsule and gently press down to completely lock the capsule. Use a gauze pad to polish the capsule and use your electronic balance to weigh the capsule. Record the weight in milligrams on the Quality Assessment Form (#9). Adjust your filling technique as needed by comparing the weight of the powder-filled capsule to the Theoretical Capsule Weight (#4). Repeat this procedure with the other nine #00 capsules until all the capsules are filled. The powder may need to be re-compacted into a smaller pile to allow the capsules to be filled effectively using the punch method. All powder should theoretically be used. Complete the Quality Assessment Form with these 10 filled capsules.

torsion balance leveling

*Except in the final step, lock your balance any time you are adjusting the legs. Keep the lid closed. STEP 1 Unlock the balance and observe where the red balance indicator rests. The red balance indicator will rest on the LOW side of the balance. STEP 2 Lock the balance and raise the LOW side of the balance by turning the leveling leg CLOCKWISE by 2-3 turns. STEP 3 If the red balance indicator is NOT within the division markings on the balance. Lock the balance and RAISE the low side of the balance by turning the leveling leg clockwise one or two turns, unlock the balance and observe the red balance indicator. STEP 4 If the red balance indicator is still not within the divisions on the balance lock and repeat the above step. STEP 5 Unlock the balance and observe the red indicator. If the indicator is within the division markings on the balance, leave the balance unlocked and SLOWLY RAISE (clockwise) the low side of the balance or SLOWLY LOWER (counterclockwise) the high side of the balance until the red indicator rests in the center. STEP 6 Lock the balance and have an instructor check.

drop dilution

- Put some water in a small beaker and put a drop of the emulsion on the surface of the water. If the drop mixes easily, the emulsion is an oil-in-water emulsion. Repeat for the second emulsion

determining least amount weighable (LAW)

Also referred to as Minimal Weighable Quantity (MWQ), Smallest Weighable Quantity (SWQ), and Least Weighable Quantity (LWQ). The accepted standard for error in pharmacy weighing and measurements is that they are to be within + or - 5% accuracy. If the sensitivity of your balance is x mg the least/smallest amount you can weigh on the balance with an accuracy of + or - 5% is determined as follows: Least Amount Weighable = Sensitivity (x)/ Accepted Error x 100%

Wet Gum Method (English)

In the wet gum method, the proportions of oil, water, and emulsifier can be the same (4:2:1), but the order of mixing is different. The 1 part emulsifier is triturated with 2 parts water to form a wetted mixture. The 4 parts oil is added slowly, in portions, while triturating. After all the oil is added, the mixture is triturated for several minutes to form the primary emulsion. Light, rapid trituration is also required to produce an emulsion by this method. Generally, the English method is more difficult to perform successfully, especially with more viscous oils, but it may result in a more stable emulsion.

weighing techniques using the electronic balance

Plug in the electronic balance. You should also calibrate the electronic balance each week before using. Your electronic balance will weigh up to 200 g. If you place anything weighing greater than 200 mg, an error message will display. The information on the next page will take you through the steps involved in operating and calibrating problems with your balance.

Dry gum (continental) method

The dry gum method is used to prepare the initial or primary emulsion from oil, water, and a vegetable derived hydrocolloid or "gum" type emulsifier (usually acacia). The primary emulsion, or emulsion nucleus, is formed from 4 parts oil, 2 parts water, and 1 part emulsifier. The 4 parts oil and 1 part emulsifier represent their total amounts in the final emulsion. In a dry mortar, the 1 part emulsifier is triturated with the 4 parts oil until the powder is wetted thoroughly. Then the 2 parts water are added all at once and the mixture is vigorously and continually triturated (usually 3 to 4 minutes) until the creamy-white primary emulsion is formed and produces a crackling sound as it is triturated (Fig. 15.3). Light, rapid trituration is the most effective way to produce an emulsion by this method.

medication measuring device exercise

This exercise is designed to demonstrate the accuracy/ inaccuracy of commonly used medication measuring devices: § Tableware teaspoon § 5 mL oral syringe § Pediatric "medication administration device" A commonly prescribed dose, particularly for pediatric antibiotic products, is 'one teaspoonful". The prescriber is actually directing that a 5 mL dose be given to the child. Unfortunately, some people use whatever "teaspoon" is most available. It might be a teaspoon from the silverware drawer in the kitchen or a plastic "teaspoon" from a fast food restaurant. DIRECTIONS: Using a 10mL cylindrical graduate, measure and record the volume of liquid delivered by each device when used to measure "a teaspoonful", or 5 mL. Fill the tableware teaspoon as full as possible without spilling. Use water provided as the pseudo-medication.Assuming that the desired amount to be administered was 5 mL, determine the percent error demonstrated by each device.

§ Use the smallest graduate that will hold the volume to be measured. § The graduate should be held at eye level § To avoid errors of parallax, the volume should always be read at the bottom of the meniscus § The viscosity of a liquid will influence how accurately you can measure a given volume

helpful hints with weighing

· Be sure to fold a crease in the middle of all your powder papers (fold into a triangle and open it back up before you put product on it); this helps keep product from falling off paper. · Do NOT let powder papers touch the torsion balance lid when weighing. · Do NOT touch torsion balance weights with hands; use powder paper to pick up. · Do NOT discard the powders and the ointment, put back into the containers.

dye-solubility

· Put some of the emulsion in a test tube and place ½ dropperful of dye solution on the emulsion and invert. If the dye solution diffuses (mixes) with the emulsion, the emulsion is an oil-in-water emulsion. Repeat the test with the second emulsion.

· Start with the balance OFF and a clear platform. · Press and hold on/zero/off button until it reads MENU. Release button. The balance should now read CAL. · Press on/zero/off button again now balance should read -C- (flashing). · Place 200g weight on balance. Press on/zero/off again. When it reads DONE, remove weight.

weighing on the VWR P-Series Balance

· Start with the balance ON. · Select the desired weighing unit by momentarily pressing Mode Off. · Place an empty container or weigh paper on the platform. · Re-zero the display (Press and hold on/zero/off for 1 sec). · Place sample on platform. · The stability indicator * appears when the reading is stable. *Note: Removing the container and material from the platform will cause the balance to display the container's weight as a negative number. The tared weight remains until on/zero/off button is pressed again, or the balance is turned off. *Electronic balances will weigh up to 200 grams INCLUDING the tared container. Be sure that your substance + container weigh less than 200 g or an error message will display.

filter paper test

·Put a drop of the emulsion on a piece of filter paper. If the drop spreads rapidly, it is an oil-in-water emulsion. Repeat for the second emulsion.
