C. Long questions: 

1. What is the Transdermal Drug Delivery System? Write its advantages.

Ans: The Transdermal Drug Delivery System (TDDS) is a novel method of administering drugs through the skin into systemic circulation at a predetermined rate. This technique helps in maintaining a steady concentration of medicine in the blood over a prolonged period. It is especially useful for drugs that are destroyed by stomach acids or extensively metabolized by the liver. Transdermal patches are an example of this system.

Advantages include:

(i) It is a painless and non-invasive method of drug administration.

(ii) Provides controlled and steady delivery of medicine for a long duration.

(iii) Useful for patients who cannot take drugs orally.

(iv) Helps to avoid gastrointestinal irritation and first-pass metabolism.

(v) Increases patient compliance and comfort.

(vi) Easy to use and self-administered.

(vii) Reduces fluctuations in drug concentration in blood.

(viii) Helps in delivering small and consistent doses.

(ix) Improves therapeutic efficiency.

(x) Beneficial for chronic disease treatment like pain therapy and addiction control.

2. What are the Seven Rights of Drug Administration? Explain.

Ans: The Seven Rights of Drug Administration are safety principles followed by healthcare workers to avoid medication errors and ensure effective treatment. These include:

(i) Right Medicine: Ensure the medicine label matches the doctor’s order.

(ii) Right Patient: Confirm patient’s identity using at least two identifiers (e.g., name, DOB).

(iii) Right Time: Medicine should be given 30 minutes before or after the prescribed time.

(iv) Right Dose: Double-check the correct dosage as prescribed.

(v) Right Route: Medicine should be given by the correct route (oral, IV, IM, etc.).

(vi) Right Form: Ensure correct form is administered (tablet, capsule, syrup, injection).

(vii) Right Documentation: Record every detail accurately in a patient’s medical record.

These rights protect both patients and healthcare providers from errors. They also ensure that the therapeutic effect of medicine is achieved while minimizing risks. Failure to follow any of these rights may lead to harmful consequences for the patient.
