Describe TWO advantages and TWO disadvantages of topical drug delivery for skin conditions.

Advantages of Topical Drug Delivery for Skin Conditions:

1. Targeted Treatment: One of the main advantages of topical drug delivery is that it allows for targeted treatment. This means that the medication is applied directly to the affected area, which can lead to more effective treatment and faster relief from symptoms.

2. Fewer Systemic Side Effects: Another advantage is that topical medications typically have fewer systemic side effects compared to oral medications. This is because the drug is not being absorbed and distributed throughout the entire body, but rather is being applied to a specific area.

Disadvantages of Topical Drug Delivery for Skin Conditions:

1. Skin Irritation: One of the main disadvantages of topical drug delivery is that it can cause skin irritation. Some people may experience redness, itching, or other types of irritation after applying the medication.

2. Inconsistent Absorption: Another disadvantage is that the absorption of the drug can be inconsistent. This is because the thickness and condition of the skin can vary, which can affect how much of the drug is absorbed. This can make it more difficult to determine the appropriate dosage and can potentially lead to less effective treatment.
