Gastrointestinal (GI) toxicity is a major drawback of the chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs). The NSAIDs topical actions on the protective phospholipid layers of the GI mucosa seem to be a central toxicity mechanism of these pharmaceuticals. This work describes the interactions of acemetacin, a commercialized NSAID, with 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) bilayers at pH 3.0, 5.0, and 7.4. This pH range was chosen to mimic the pH gradient found in the gastric mucosa, and to ultimately gain insights into the mechanisms underlying the acemetacin-induced gastric toxicity...

Systemic contact dermatitis (SCD) traditionally refers to a skin condition where an individual who is cutaneously sensitized to an allergen will subsequently react to that same allergen or a cross reacting allergen via a different route. It occurs to allergens including metals, medications, and foods. The exact pathophysiology underlying this disease remains unknown, although it appears to be mediated by type 4 hypersensitivity reactions and possibly type 3 hypersensitivity reactions. The p-I concept (pharmacologic interaction with immunoreceptors) hypothesized that drugs are able to bind directly to a T cell receptor without first being presented by MHC (major histocompatibility complex) molecules and without prior metabolism, which would help explain why SCD can be seen on first exposure to medications...

INTRODUCTION: Little is known of the ocular distribution characteristics of currently branded non-steroidal anti-inflammatory drugs (NSAIDs) in the United States. This study was designed to predict the ocular bioavailability characteristics in humans using Dutch Belted rabbits as a surrogate. Commercially available, topically-applied NSAIDs containing bromfenac or nepafenac/amfenac were evaluated. METHODS: 126 healthy adult Dutch Belted rabbits were randomly assigned to three treatment cohorts (BromSite® twice daily [BID] in the right eye, BromSite® once daily [QD] in the right eye, Prolensa® QD in the right eye and Ilevro™ QD in the left eye) and 7 post-dosing time points (0...

Topical non-steroidal anti-inflammatory drugs (NSAIDs) patches are indispensable for the treatment of musculoskeletal diseases, while they are considered less effective than oral NSAIDs. LOQOA® tape is a tape-type patch containing esflurbiprofen (SFP) as a major active ingredient with potent cyclooxygenase inhibition and sufficient skin permeability. SFP patch (SFPP) showed higher percutaneous absorption rate, rapid pain relief, and potent anti-inflammatory efficacy comparing with existing NSAIDs patches in rat...

Topical corticosteroids are effective anti-inflammatory drugs in the treatment of anterior uveitis. The intraocular efficacy of topical corticosteroids mostly depends on their intraocular permeability through the cornea. Lipophile derivatives such as dexamethasone and prednisolone acetate penetrate better into the anterior chamber than hydrophilic derivatives. Prednisolone acetate 1% is the first choice in the therapy of patients with anterior uveitis. Loteprednole and fluorometholone have a slightly weaker anti-inflammatory effect, but they induce less elevation of intraocular pressure and might be helpful in the treatment of patients with steroid response...

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) and particularly selective cyclooxygenase-2 (COX-2) inhibitors such as celecoxib (Cxb) are considered promising cancer chemopreventive for colon, breast, prostate, lung, and skin cancers. However, the clinical application to the prevention is limited by concerns about safety, potential to serious toxicity (mainly for healthy individuals), efficacy and optimal treatment regimen. Cxb exhibits advantages as potent anti-inflammatory and gastrointestinal tolerance compared with conventional NSAID's...

Dry eye disease (DED), an inflammatory disease of the ocular surface, affects 15% of humans worldwide. No satisfactory treatment exists for DED partly because of the lack of informative animal models of this disease. We evaluated the anti-inflammatory phosphosulindac (PS) for the treatment of DED using a new rabbit model of chronic DED. In this model, based on the concanavalin A (Con A) acute DED model, we injected all lacrimal glands with Con A 3 times weekly under ultrasound guidance, which prolonged DED to >3 weeks, and used concurrently 4 parameters of efficacy: tear break-up time (TBUT), tear osmolarity, Schirmer test, and tear lactoferrin levels, making efficacy assessment robust...

AIM: To evaluate the efficacy of prophylactic administration of topical non-steroidal anti-inflammatory drugs (NSAIDs) on macular edema following cataract surgery in diabetic patients, and to compare between types of NSAIDs (ketorolac tromethamine 0.4% and nepafenac 0.1%). METHODS: Group 1 (control) received artificial tears substitute as a placebo group, group 2 (nepafenac) received topical nepafenac 0.1%, and group 3 (ketorolac) received topical ketorolac tromethamine 0...

Actinic keratoses (AKs) are atypical, precancerous proliferations of keratinocytes that develop because of chronic exposure to ultraviolet (UV) radiation. Treatment of AK can be lesion-directed or field-directed. Field cancerization theory postulates that the skin surrounding AK is also at increased risk for possible malignant transformation since it has been exposed to the same chronic UV light. Field-directed therapies thus have the potential to address subclinical damage, reduce AK recurrence rates, and potentially reduce the risk of squamous cell carcinoma (SCC) development...

The comprehensive treatment of pain is multidimodal, with pharmacotherapy playing a key role. An effective therapy for pain depends on the intensity and type of pain, the patients' age, comorbidities, and appropriate choice of analgesic, its dose and route of administration. This review is aimed at presenting current knowledge on analgesics administered by transdermal and topical routes for physicians, nurses, pharmacists, and other health care professionals dealing with patients suffering from pain. Analgesics administered transdermally or topically act through different mechanisms...

PURPOSE: Spontaneous osteonecrosis of the knee affects the medial femoral condyle in patients above 55 years of age. Many reports and studies are available from western countries. But there is a gross paucity of literature on spontaneous osteonecrosis of the knee (SPONK) in the Indian subcontinent, either it is under-reported or detected at a later stage. The aim of our study was to detect SPONK in Indian population and describe its characteristics, treatment, and outcome.

Photosensitization by drugs is a problem of increasing importance in modern life. This phenomenon occurs when a chemical substance in the skin is exposed to sunlight. Photosensitizing drugs are reported to cause severe skin dermatitis, and indeed, it is generally advised to avoid sunbathing and to apply sunscreen. In this context, the nonsteroidal anti-inflammatory drug (NSAID) diclofenac is a photosensitive drug, especially when administered in topical form. In this work, efforts have been made to design and study an innovative pro-drug/pro-filter system containing diclofenac and the UVA filter avobenzone in order to develop a safer use of this topical drug...

BACKGROUND: The optimal treatment of superficial thrombophlebitis (ST) of the legs remains poorly defined. While improving or relieving the local painful symptoms, treatment should aim at preventing venous thromboembolism (VTE), which might complicate the natural history of ST. This is the third update of a review first published in 2007. OBJECTIVES: To assess the efficacy and safety of topical, medical, and surgical treatments for ST of the leg in improving local symptoms and decreasing thromboembolic complications...

Episcleritis is the inflammation of the thin, loose, highly vascular connective tissue layer that lies between the conjunctiva and sclera. Incidence is less than 1/1000. It is more common in women and those between 40 and 50 years of age. Most cases are idiopathic. It is classified into simple and nodular. Most attacks resolve within 1-3 months. The nodular type tends to be more recurrent and painful. It presents with acute onset of redness, lacrimation, and photophobia. The diagnosis of is essentially clinical, and eye pain or tenderness should raise the concern for scleritis...
