Summary
Laser-assisted drug delivery (LADD) enhances topical treatment by creating skin microchannels for improved drug penetration. While promising for skin conditions, further research is needed to optimize techniques and address challenges.
Area of Science:
- Dermatology
- Biomedical Engineering
- Pharmaceutical Sciences
Background:
- Topical drug delivery is preferred for skin diseases but limited by the skin's barrier function.
- Drug penetration into deeper skin layers remains a significant challenge for conventional topical treatments.
- Laser-assisted drug delivery (LADD) offers a novel approach to overcome these limitations.
Purpose of the Study:
- To evaluate the potential of laser-assisted drug delivery (LADD) as an enhanced method for topical treatment of skin conditions.
- To explore how LADD can improve drug penetration through the skin's natural barrier.
- To identify challenges and future research directions for LADD implementation in dermatology.
Main Methods:
- Utilizing lasers, such as fractional CO2, to create transient microchannels in the skin.
- Facilitating the deposition and enhanced penetration of therapeutic agents into the dermal and epidermal layers.
- Conducting preclinical and clinical studies to assess LADD efficacy and safety.
Main Results:
- LADD demonstrates promising outcomes in preclinical and clinical studies for improved drug delivery.
- Microchannel creation by lasers significantly enhances drug penetration compared to conventional topical methods.
- Studies indicate potential for LADD in treating various dermatological disorders, including skin cancers and scars.
Conclusions:
- Laser-assisted drug delivery (LADD) presents a viable strategy to overcome topical treatment limitations in dermatology.
- Optimization of laser parameters, drug formulations, and addressing safety concerns are critical for widespread LADD adoption.
- Continued advancements in LADD technology hold the potential to revolutionize dermatological treatments and patient care.

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

01:16Drug Delivery: Overview
285
The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...

212
Non-oral extravascular routes, which encompass sublingual, buccal, topical, intramuscular, and inhalation methods, primarily utilize passive diffusion to transport drugs into the systemic circulation. The absorption rates and effectiveness of these routes depend on the drug's physicochemical properties, as well as the patient's anatomical and pathophysiological state.

01:29Drug Delivery: Parenteral Route

The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.

The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.
