Drug Recall Classes

PTCB

Definition

FDA: Class I (serious/death), Class II (temporary adverse), Class III (unlikely adverse).

Differential Diagnosis

Distinguishing between related concepts for drug recall classes:

Benzodiazepines: Examples: lorazepam, diazepam, alprazolam, midazolam. Mechanism: Enhance GABA-A receptor, increased chloride conductance, CNS depression. Key side effects: Sedation; Respiratory depression.

Beta blockers: Examples: metoprolol, atenolol, propranolol, carvedilol. Mechanism: Block beta-adrenergic receptors, decrease heart rate and contractility. Key side effects: Bradycardia; Fatigue.

Step-by-Step Procedure

FDA: Class I (serious/death), Class II (temporary adverse), Class III (unlikely adverse). Recall classes and technician responsibilities tested on PTCB exam.

Related drug class: ACE inhibitors includes lisinopril, enalapril, ramipril. Mechanism: Block angiotensin-converting enzyme, decrease angiotensin II, cause vasodilation and decreased aldosterone.

Practical Example

Pharmacy Calculation Example: percentage strength

Formula: w/v: g/100mL, w/w: g/100g, v/v: mL/100mL

Worked example: 2% hydrocortisone cream = 2g HC per 100g cream

Assessment Techniques

FDA: Class I (serious/death), Class II (temporary adverse), Class III (unlikely adverse). Recall classes and technician responsibilities tested on PTCB exam.

Related drug class: SSRIs includes sertraline, fluoxetine, escitalopram, paroxetine. Mechanism: Selectively inhibit serotonin reuptake in synaptic cleft, increase 5-HT activity.

Key Values & Ranges
