Active Ingredients Absorption Through the Skin: Transdermal Patches

Transdermal patches are an innovative drug delivery form that allows the release of active substances through the skin. By placing these patches on the skin, the active ingredient is continuously and gradually introduced into the bloodstream, ensuring a systemic effect that impacts the entire body. The advantage of this method is that medication administration becomes simpler, and the active substances maintain a steady blood level, which is particularly important during long-term treatments.

The operation of transdermal patches originates from a reservoir of active substances that release the active ingredient through various types of membranes or matrices. The patches used during therapy have different advantages and disadvantages, which are important for users, whether for pain relief or the treatment of other health issues. It is worthwhile to thoroughly understand how to use the patches to achieve maximum effectiveness.

Advantages of Transdermal Patches

Transdermal patches come with numerous advantages that are becoming increasingly popular in modern medicine. One of the most significant benefits is the possibility of long-term and continuous medication delivery. These patches can remain on the skin for up to 7 days, making treatment easier for patients, as multiple daily doses are not required. This is particularly important for chronic patients, for whom regular dosing is essential.

The absorption of active substances is independent of meals and does not irritate the gastrointestinal tract, allowing patients to feel more comfortable during treatment. The patches help avoid first-pass metabolism by the liver, thus maintaining the effectiveness of the active substances. This can be particularly advantageous for rapidly metabolizing drugs, such as heart medications. Furthermore, patches can be used for pain relief, especially for oncology patients who need sustained analgesic effects.

Patches can be quickly removed, so if any side effects occur, the patient can immediately stop the treatment. The dosing is precise and even, which reduces the risk of overdose, ensuring the safety of treatments.

Disadvantages of Transdermal Patches

Although transdermal patches have numerous advantages, they are not without drawbacks. One significant limitation is the relatively low amount of active substance that can be absorbed through the skin. The absorption surface of the patches is small, so they can only deliver a limited amount of active substance. Additionally, users may experience skin irritation with prolonged use.

The effects of the patches are not immediate, making them unsuitable for treating acute conditions. Moreover, the patches may contain metallic layers that can heat up in a magnetic field, so these materials must be removed from the skin during use. The manufacturing of transdermal drug forms is also costly, which can affect accessibility.

During application, it is important for the patient to follow precise usage instructions to avoid potential side effects and complications. Skin irritation, rapid release of the active substance, or the patch falling off are all issues that require attention.

Application of Transdermal Patches

To ensure the effective application of transdermal patches, it is crucial to adhere to the proper guidelines. First, the area of skin where the patch will be applied must be cleaned with water and dried. The skin should be intact, irritation-free, and hairless to ensure good adhesion of the patch. It is advisable to avoid easily wrinkled body parts, such as around joints.

Before applying the patch, check that it is intact, then remove the protective film without touching the surface that contains the active ingredient. Secure the patch to the skin with gentle pressure, and then wash your hands. When changing the patch, it is important to always choose a new skin area to avoid skin irritation.

When applying the patches, be careful not to use a pen on the surface of the patch and avoid exposing the patch to water, as this may alter the release of the active substance. If the patch falls off, a new patch should be placed on another clean surface, and treatment should continue as usual. Unused parts of the patches should always be stored in a closed place and returned to the pharmacy.

These guidelines help ensure that transdermal patches effectively exert their effects while minimizing potential risks. It is important for patients to regularly consult with their doctors regarding the use of patches to ensure proper dosing and application.
