Pharmacy Technician Guidelines for Handling Expired Medications:Analysis of Answer Choices:References for Pharmacy Technicians:

Pharmacy staff should always visually inspect nonsterile compounds for signs of incompatibility to ensure medication safety and efficacy. The presence ofprecipitationis a key indicator of an incompatibility issue in nonsterile compounded preparations. Precipitation occurs when a solute (drug) comes out of solution, forming visible solid particles. This can result from changes in pH, solvent composition, or chemical interactions between ingredients.

A. Photolysis:

Decomposition of a drug due to light exposure, leading to color changes or potency loss, but it is not a physical incompatibility visible as precipitation.

B. Hydrolysis:

Chemical breakdown of a drug due to water, common in ester and amide-containing drugs, but not a visual incompatibility like precipitation.

D. Oxidation-Reduction:

A chemical reaction that may change drug color or effectiveness but does not typically lead to visible precipitation in nonsterile compounds.

Remington: The Science and Practice of Pharmacy

To determine the correct volume of amoxicillin suspension per dose, use the given concentration and dose.

Prescription dose:150 mg per dose

Suspension concentration:250 mg per 5 mL

Formula to calculate volume needed:Volume (mL)=Prescribed dose (mg)Concentration (mg/mL)\text{Volume (mL)} = \frac{\text{Prescribed dose (mg)}}{\text{Concentration (mg/mL)}}Volume (mL)=Concentration (mg/mL)Prescribed dose (mg)​

Step 1: Identify Given InformationStep 2: Calculate150 mg250 mg/5 mL=150×5250=750250=3 mL\frac{150 \text{ mg}}{250 \text{ mg/5 mL}} = \frac{150 \times 5}{250} = \frac{750}{250} = 3 \text{ mL}250 mg/5 mL150 mg​=250150×5​=250750​=3 mL

Thus, the patient should take3 mL per dose.

B. 4 mL→ Incorrect; this would correspond to a different strength.

C. 5 mL→ Incorrect; this would deliver250 mg, which is incorrect.

D. 6 mL→ Incorrect; this would deliver300 mg, exceeding the prescribed dose.

USP <795> Guidelines for Nonsterile Compounding & Drug Dilution

Lexicomp Drug Monograph for Amoxicillin Suspension

AMaster Formulation Record (MFR)is adetailed document used in compounding pharmaciesto ensureconsistency, accuracy, and quality controlin preparing compounded medications.

An MFR includes:

Ingredients & amounts required.

Compounding procedures.

Stability and beyond-use dating (BUD).

Storage and labeling instructions.

This ensures that each compounded preparationmeets quality standardsand ismade correctly every time.

B. Prevent drug diversion❌→Incorrect

Drug diversion prevention involves security measures, inventory control, and trackingcontrolled substances, not MFRs.

C. Eliminate patient profiles❌→Incorrect

Patient profiles are essential for tracking medication history; MFRs are unrelated.

D. Guarantee drug availability❌→Incorrect

MFRs do not affect drug supply; they ensure accurate compounding.

USP <795> (Non-Sterile Compounding Guidelines)– RequiresMaster Formulation Records for all compounded preparations.

Look-alike/sound-alike (LASA) medications pose asignificant risk of medication errors. To reduce this risk, pharmacies should:

Use both brand and generic nameson labels to clarify drug identity.

Example:"Celexa (Citalopram)" vs. "Celebrex (Celecoxib)."

B. Place the drug next to another look-alike/sound-alike drug on the shelf if they are alphabetical.❌→Incorrect

LASA drugs shouldnotbe stored next to each other.

Example:Hydroxyzine and Hydralazine should be stored separatelyto avoid mix-ups.

C. Review the first five digits of the NDC to confirm the correct product.❌→Incorrect

The first five digits (manufacturer code) only identify the manufacturer, not the specific drug.

Instead, checking theentire NDC (all 10-11 digits) is necessary.

D. Take hazardous drug precautions.❌→Incorrect

LASA errors are a labeling issue, not a hazardous drug issue.

Institute for Safe Medication Practices (ISMP) LASA Guidelines– Recommends usingboth brand and generic names on labels.

FDA & Joint Commission LASA Drug Safety Recommendations– Emphasizes labeling improvements for LASA drugs.

ANarrow Therapeutic Index (NTI) drugis a medication in whichsmall differences in dose or blood concentrationcan lead to serioustoxicityorsubtherapeutic effects. These drugs requirecareful dosing and monitoringto avoid adverse effects or treatment failure.

Small Margin of Safety:The difference between theminimum effective concentration (MEC)and theminimum toxic concentration (MTC)is very narrow.

Requires Therapeutic Drug Monitoring (TDM):Blood levels of the drug must be regularly monitored to maintain efficacy while avoiding toxicity.

High Risk of Adverse Effects:Even minor dosage adjustments or variations in patient metabolism can cause toxicity.

Strict Pharmacokinetic and Pharmacodynamic Considerations:Factors likerenal and hepatic function, drug interactions, and patient weightsignificantly impact the drug’s effect.

Warfarin (Coumadin) → Risk of bleeding.

Digoxin → Risk of toxicity affecting the heart.

Phenytoin → Risk of severe neurological effects.

Levothyroxine → Risk of under- or over-treatment of thyroid disorders.

Theophylline → Risk of respiratory or cardiac toxicity.

Carbamazepine → Risk of serious neurological side effects.

A. Shorter window of guaranteed stability.→ Incorrect. NTI drugs do not necessarily have a shorter shelf-life or stability concerns compared to other drugs. Stability depends on formulation and storage conditions.

B. Incompatibility with therapeutic monitoring.→ Incorrect. NTI drugsrequiretherapeutic monitoring, not the opposite.

C. Synergistic effect on other medications.→ Incorrect. While NTI drugs can interact with other drugs, not all exhibit a synergistic effect (where combined drugs produce a greater effect than expected).

In the providedcompounded prescription, the antifungal agent isnystatin.

Nystatin is a polyene antifungalthat works by binding toergosterolin fungal cell membranes, causing leakage of cellular contents and fungal cell death.

It iscommonly used for fungal infections, particularlycutaneous or mucosal Candida infections(e.g., diaper rash, oral thrush).

A. Cholestyramine.→ Incorrect. Cholestyramine is abile acid sequestrantused to lowercholesteroland treatdiarrhea(often in combination with other ingredients for skin irritation or wounds).

B. Hydrocortisone.→ Incorrect. Hydrocortisone is acorticosteroidused to reduceinflammation and itching, but it does not kill fungi.

C. Zinc oxide.→ Incorrect. Zinc oxide is askin protectantused fordiaper rash and minor burns, but it is not an antifungal.

Lorazepam oral concentrate is a high-potency liquid formulation often dispensed in 2 mg/mL. Due to its strength and risk of dosing errors, it must be dispensed with a calibrated oral syringe for accurate dosing, especially in pediatric or geriatric patients.

From Pharmacy Technician Certification Exam Review:

“Concentrated oral liquids should always be dispensed with calibrated measuring devices to prevent overdose or underdose.”

Other options:

Enoxaparin – subcutaneous injection

Albuterol/ipratropium – inhalation

Polyethylene glycol 3350 – powder mixed with water (no syringe required)
