We specialize in formulating films for transdermal delivery. Transdermal patches are medicated adhesive patches that provide a specific dose of medication through the skin directly into the bloodstream. This method of drug delivery is beneficial as it bypasses the gastrointestinal tract, reducing potential side effects and improving therapeutic outcomes.
- Small Molecules: Insoluble compounds, new chemical entities.
- Controlled Substances: Schedule I-V.
Using our deep knowledge of excipients, including emulsifiers, stabilizers, penetration enhancers, and emollients, we create advanced systems that optimize drug properties and ensure effective tissue penetration by manipulating the physical and chemical properties of drug products.
How It Works?
- Mechanism of Action: Transdermal patches work by housing medication within a thin adhesive layer that adheres to the skin. The drug release is meticulously controlled by a backing membrane, ensuring a steady diffusion of medication through the skin over time.
- Advantages: The use of transdermal patches offers several advantages over traditional oral medications, including avoiding first-pass metabolism, providing consistent plasma levels, and improving patient compliance due to their ease of use.
- Drug Formulation: The formulation of drugs for transdermal patches is a critical aspect. It often includes permeation enhancers that aid in the absorption of the medication through the skin barrier.
- Application Sites: Transdermal patches should be applied to clean, dry, and hairless skin areas with little movement, such as the upper arm, chest, or back, to ensure optimal drug absorption and patch adhesion.
- Duration of Use: Depending on the medication, transdermal patches can be designed for short-term or long-term use, ranging from a few hours to several days, providing controlled and sustained delivery of medication.
- Patient Education: It is essential to educate patients on the correct use of transdermal patches, including application techniques, rotation of sites, and disposal methods to maximize efficacy and minimize side effects.
- Potential Side Effects: While transdermal patches reduce gastrointestinal side effects, they may cause local skin reactions such as redness, itching, or irritation at the application site.
- Types of Transdermal Patches: There are various types of transdermal patches, including single-layer drug-in-adhesive, multi-layer drug-in-adhesive, reservoir, and matrix patches. Each type is designed to cater to different drug properties and therapeutic needs.

FAQs
Here are some frequently asked questions about Transdermal Patches
What are transdermal patches and how do they work?
Transdermal patches are medicated adhesive patches designed to deliver a specific dose of medication through the skin and into the bloodstream. They work by providing a controlled release of drugs over an extended period, ensuring a consistent therapeutic level in the body. This is achieved through a combination of the patch's adhesive properties, the permeability of the skin, and the drug's formulation, which together facilitate the drug's absorption into the systemic circulation.
What types of drugs can be delivered through transdermal patches?
A wide variety of drugs can be delivered through transdermal patches, including but not limited to hormones (such as estrogen and testosterone), pain relievers (such as fentanyl), nicotine (for smoking cessation), and cardiovascular drugs (such as nitroglycerin). The suitability of a drug for transdermal delivery depends on its molecular weight, solubility, potency, and the drug's ability to penetrate the skin barrier.
What are the advantages of using transdermal patches over traditional dosage forms?
Transdermal patches offer several advantages, including:
Improved Compliance: Easy to use and requiring less frequent dosing than oral medications or injections.
Steady Medication Levels: Provides a controlled release of medication, which helps maintain consistent drug levels in the bloodstream.
Reduced Side Effects: Minimizes the risk of gastrointestinal side effects and avoids the first-pass metabolism in the liver, potentially reducing the overall side effect profile.
Non-Invasive: Offers a needle-free alternative to injections, improving patient comfort.
What Are the Key Considerations in Formulating Oral Suspensions and Solutions?
Formulating oral suspensions and solutions involves several key considerations, including solubility enhancement, taste masking, viscosity adjustment, and preservative efficacy. The formulation must ensure physical and chemical stability, acceptable palatability, and compliance with regulatory requirements. The choice of excipients and the manufacturing process must also be optimized to ensure product quality and consistency.
How do you ensure the quality and safety of transdermal patches?
Quality and safety of transdermal patches are ensured through rigorous testing and quality control measures, including:
Raw Material Testing: Screening all materials used in the patch for purity and safety.
Process Validation: Validating manufacturing processes to ensure consistent product quality.
Release Testing: Testing each batch for drug content, adhesion properties, and drug release rate.
Stability Testing: Assessing the product's stability under various environmental conditions to determine shelf life.
Clinical Trials: Conducting clinical trials to evaluate the patch's safety and efficacy in humans.
What regulatory considerations are involved in the manufacture of transdermal patches?
Manufacturing transdermal patches involves compliance with regulatory requirements set by health authorities such as the FDA (U.S. Food and Drug Administration) and EMA
(European Medicines Agency). Key considerations include:
Good Manufacturing Practices (GMP): Adhering to GMP guidelines to ensure product quality and safety.
Submission of Regulatory Dossiers: Preparing and submitting detailed information on the patch's formulation, manufacturing process, quality control, and clinical data.
Post-Market Surveillance: Monitoring the product's performance and safety after market approval.
Can transdermal patches be customized for different release profiles?
Yes, transdermal patches can be engineered to provide various release profiles, including immediate release, delayed release, or sustained release, depending on the therapeutic needs. This is achieved through adjustments in the formulation, the design of the drug reservoir, and the selection of the rate-controlling membrane or adhesive.
What are the challenges in formulating transdermal patches?
Formulating transdermal patches presents several challenges, such as:
Skin Barrier Penetration: Enhancing the drug's ability to penetrate the skin barrier without causing irritation or damage.
Drug Stability: Ensuring the stability of the drug within the patch environment over its intended shelf life.
Adhesive Selection: Choosing an adhesive that ensures the patch remains securely attached to the skin while not causing irritation or allergic reactions.
Controlled Release: Achieving a consistent and controlled release rate of the drug over the patch's active life.
How are transdermal patches tested for efficacy and safety?
Transdermal patches are tested for efficacy and safety through a combination of in vitro studies, animal studies, and clinical trials in humans. These tests evaluate the patch's pharmacokinetics, pharmacodynamics, adhesion properties, skin irritation potential, and overall therapeutic effectiveness. Regulatory authorities require comprehensive data from these tests before granting approval for market release.
What support services do CDMOs offer for transdermal patch development?
