2. Hands-on Administration Protocols for Specialized Dosage Forms
💡 Core Concept & Clinical Context:
Improper administration technique of specialized devices (Metered Dose Inhalers - MDIs, Insulin Pens, Eye Drops) is the leading cause of treatment failure in respiratory, endocrine, and ophthalmic conditions. Pharmacists must provide step-by-step physical demonstrations using placebo training devices.
Clinical Scenarios & Pharmacopoeial Examples:
1Step-by-Step Patient Protocols for Inhalers, Insulin & Eye Drops
Precise clinical instructional sequences.
Step-by-Step Breakdown:
•A. Pressurized Metered Dose Inhaler (pMDI) Protocol:
•1. Remove cap and shake inhaler vigorously for 5 seconds.
•2. Breathe out gently and completely away from device.
•3. Place mouthpiece between teeth and seal lips tightly around it.
•4. Start breathing in slowly and deeply through mouth; simultaneously press canister down ONCE.
•5. Continue inhaling slowly for 3-5 seconds.
•6. Remove inhaler and hold breath for 10 seconds (or as long as comfortable) to allow drug settling.
•7. Breathe out gently. If corticosteroid inhaler, rinse mouth with water and spit out to prevent oral candidiasis.
•B. Subcutaneous Insulin Pen Protocol:
•1. Wash hands; wipe rubber seal with alcohol swab; attach new sterile needle.
•2. Prime device with 2 units (air shot) to clear air bubbles; check for droplet at needle tip.
•3. Dial prescribed dose units.
•4. Pinch a fold of clean skin on abdomen (at least 2 inches away from navel).
•5. Insert needle at 90-degree angle; press push-button completely.
•6. Hold needle in place for 10 full seconds before withdrawing to prevent drug backflow.
•7. Safely discard needle in puncture-resistant sharps container.
•C. Ophthalmic Eye Drop Protocol:
•1. Wash hands thoroughly. Tilt head back and look upward.
•2. Gently pull lower eyelid down with index finger to form a small pocket (conjunctival sac).
•3. Hold dropper tip close without touching eye, eyelashes, or skin (preserves sterility).
•4. Squeeze one single drop into pocket.
•5. Close eyes gently for 2 minutes; apply gentle pressure to nasolacrimal duct (inner corner of eye) to prevent systemic absorption.
📋Key Takeaways & Exam Highlights
- MDI Inhaler: Holding breath for 10 seconds ensures aerodynamic sedimentation of aerosol droplets into peripheral bronchioles.
- Corticosteroid Inhalers: Mandatory post-inhalation oral rinsing prevents local oral candidiasis (thrush) and dysphonia.
- Insulin Rotation: Rotate injection sites across abdominal quadrants to prevent lipohypertrophy.
- Nasolacrimal Occlusion: Applying finger pressure to the inner eye corner for 1-2 minutes minimizes systemic cardiovascular absorption of beta-blocker eye drops (e.g. Timolol).

इनहेलर लेने के बाद 10 सेकंड सांस रोकना जरूरी है, और स्टेरॉयड इनहेलर के बाद कुल्ला करना चाहिए। आई ड्रॉप डालते समय आंख के भीतरी कोने को 1 मिनट दबाने से दवा पूरे शरीर में नहीं फैलती।
