Localized neuropathic pain (LNP) is a type of neuropathic pain characterized by consistent and circumscribed area(s) of maximum pain, which are associated with negative or positive sensory signs and/or spontaneous symptoms typical of neuropathic pain. This description outlines the clinical features of a group of pathologies, in which a LNP can be diagnosed and for whom topical targeted treatment with 5% Lidocaine medicated plaster can be suggested. Indeed both American as well as European guidelines already suggest 5% Lidocaine medicated plaster as a first line treatment in post herpetic neuralgia and in general in the treatment of conditions such as diabetic painful polyneuropathy and post surgical pain where a LNP can be ascertain...

The capsaicin 8% patch can effectively treat neuropathic pain, but application can cause discomfort or a burning sensation. Until March 2013, it was recommended that patients be pretreated with a topical anesthetic, for example lidocaine, before capsaicin patch application. However, speculation existed over the need for pretreatment and its effectiveness in alleviating treatment-associated discomfort. This article compares tolerability to and efficacy of the capsaicin patch in pretreated and non-pretreated patients...

BACKGROUND: Osteoarthritis is a relatively common musculoskeletal disorder that increases in prevalence with age. Worldwide, knee osteoarthritis is one of the leading causes of disability, particularly in the elderly. In numerous trials of agents for long-term pain therapy, no well-established and replicable results have been achieved. Complementary and alternative medical approaches have been employed for thousands of years to relieve knee osteoarthritis pain. Among herbal medicines, the golden plaster is the preferred and most commonlyused method in China to reduce pain in patients with knee osteoarthritis, as it causes few adverse effects...

AIM: Muscle injuries and extensive exercise are associated with cyclo-oxygenase dependent formation of inflammatory prostaglandins. Since the effect of topical administration of non-steroidal anti-inflammatory drugs (NSAIDs) on local cyclo-oxygenase is unknown, the present exploratory, open label, non-randomized study set out to measure exercise induced release of prostaglandins before and after epicutaneous administration of diclofenac. METHODS: Microdialysis was used to determine the local interstitial concentration of PGE2 and 8-iso-PGF2α as well as diclofenac concentrations in the vastus lateralis under rest, dynamic exercise and during recovery in 12 healthy subjects at baseline and after a treatment phase applying a total of seven plasters medicated with 180 mg of diclofenac epolamine over 4 days...

To improve the poor compatibility among different components of Drug-in-adhesive type patch, two novel plasters (Drug-in-fiber and Drug-in-adhesive/fiber) were developed based on ibuprofen (IBU)-loaded fiber mats. These fibrous mats were fabricated via electrospinning of cellulose acetate/poly(vinylpyrrolidone) composites in a binary solvent of N,N-dimethyl acetamide/acetone. Physical status studies suggested that Drug-in-fiber could inhibit IBU re-crystallization, but the active ingredients were released at a relatively slow rate due to the dual-resistance of fiber mat and adhesive matrix...

INTRODUCTION: Transdermal patches and medicated plasters (patch) represent well-established prolonged release dosage forms. Even if satisfactory adhesion to the skin is strictly linked to the efficacy and safety of the therapeutic treatment, nowadays numerous reports of in vivo 'adhesion lacking' are still addressed to regulatory agencies. The adhesive properties of a patch should be characterized considering i) the ability to form a bond with the surface of another material on brief contact and under light pressure (tack); ii) the resistance of the adhesive to flow (shear adhesion); and iii) the force required to peel away a patch from a surface (peel adhesion)...

Opioids have been used for thousands of years for pain relief. Transdermal fentanyl (TDF) is a synthetic opioid that is prescribed for the treatment of chronic pain. This clinical lesson demonstrates that TDF may be easy to start but sometimes difficult to stop. Like any other opioid there is a substantial risk of physical dependence and subsequent withdrawal symptoms after discontinuation of the drug. Here, we present a case of a hospice patient who developed withdrawal symptoms after a first TDF tapering attempt according to the manufacturer's instructions...

BACKGROUND: In general sports, ankle sprain is the most frequently reported ankle injury and can cause chronic lateral ankle pain and tenderness. Treatment with NSAIDs is preferred, and several topical NSAID formulations are now available, helping to avoid the systemic adverse events typically associated with oral preparations. OBJECTIVE: To compare the efficacy and tolerability of a newly developed fixed-dose diclofenac epolamine (diclofenac hydroxyethylpyrrolidine, DHEP)/heparin plaster (Flectoparin® Tissugel) with that of a DHEP (Flector EP Tissugel®) or placebo plaster in the treatment of mild to moderate ankle sprain in adults...

A transdermal therapeutic system for scopolamine (TTS-S) was developed to counter the adverse effects and short duration of action that has restricted the usefulness of scopolamine when administered orally or parenterally. The plaster contains a reservoir of 1.5 mg of scopolamine programmed to deliver 0.5 mg over a 3-day period. A priming dose (140 microg) is incorporated into the adhesive layer to saturate certain binding sites within the skin and to accelerate the achievement of steady-state blood levels...

The alkaloid L-(-)-scopolamine [L-(-)-hyoscine] competitively inhibits muscarinic receptors for acetylcholine and acts as a nonselective muscarinic antagonist, producing both peripheral antimuscarinic properties and central sedative, antiemetic, and amnestic effects. The parasympatholytic scopolamine, structurally very similar to atropine (racemate of hyoscyamine), is used in conditions requiring decreased parasympathetic activity, primarily for its effect on the eye, gastrointestinal tract, heart, and salivary and bronchial secretion glands, and in special circumstances for a CNS action...

Transdermal patches were developed and evaluated for two synthetic derivatives of capsaicin, nonivamide (NVA) and sodium nonivamide acetate (SNA), by in vitro and in vivo skin permeation. The designed system was essentially based on natural rubber or polymeric Gelva dispersion. The characterization of physicochemical properties of the patches showed adequate adhesive force and low thickness which suggested these patch formulations possessed good quality. In the study of in vitro percutaneous experiment, the predicted therapeutic activities of patches were all higher than that of a commercially available plaster after the calculation of antinociceptive index...

Flector plaster is a new transdermal delivery system medicated with diclofenac hydroxyethylpyrrolidine salt, an NSAID which seems to possess suitable physiochemical properties for easy release by the plaster matrix for percutaneous absorption. The paper deals with local tolerability and pharmacokinetic (percutaneous absorption) studies carried out both on animals and on volunteers. The results obtained in the safety studies demonstrate the absence of local skin reactions and of sensitization phenomena. The kinetic evidence, obtained at the steady-state, reveals a profile typical of a sustained-release formulation, able to maintain constant plasma levels of the drug up to the next application (12 h)...
