Doxycyline is a tetracycline derivative that is often used for ocular skin disorders when penicillin is contraindicated. It is often the drug of choice for ocular rosacea, as well as chronic lid infections. Doxycyclin ist ein Antibiotikum aus der Klasse der Tetracycline. Es besitzt ein breites Wirkspektrum und zeigt eine bakteriostatische Wirksamkeit auf grampositive, gramnegative und zellwandlose Keime. Der Wirkungsmechanismus von Doxycyclin beruht auf einer Hemmung der Proteinbiosynthese. Durch eine reversible Blockade der Bindungsstelle der Aminoacyl-t-RNS an der 30S-Untereinheit des Ribosoms wird die Elongation der Peptidkette unterbrochen. Entsprechend seinem Wirkspektrum wird Doxycyclin zur Behandlung von Atemwegserkrankungen, Infektionen des Urogenitaltrakts, Infektionen des Magen-Darm-Trakts, Gallenwegsinfektionen, Akne, Rosazea, Chlamydien-Infektionen, Borreliose sowie bei zahlreichen seltenen Infektionen, wie zum Beispiel Pest und Milzbrand, eingesetzt. allerdings gibt es in Deutschland für diese Indikation keine zugelassenen Fertigarzneimittel. Während der Einnahme von Tetracyclinen, einschließlich Doxycyclin, wurde bei einigen Patienten eine Photosensibilisierung beobachtet. Es entsteht nach Sonnen- oder UV-Strahlung ein ausgeprägter Sonnenbrand.

Doxycycline hyclate is a semisynthetic tetracycline functioning as a broad spectrum antibiotic and bacteriostatic agent effective against Gram-positive and. According to a recent meta-analysis, there is only one small study that has shown that a combination of dextromethorphan and quinidine alleviates symptoms of easy laughing and crying (pseudobulbar affect) in patients with amyotrophic lateral sclerosis and multiple sclerosis. Although intravenous quinidine is sometimes used to treat Plasmodium falciparum malaria, its US manufacturer, Eli Lilly, no longer manufactures quinidine and the future availability of this agent in the US and other countries is uncertain. Quinidine is also an inhibitor of the cytochrome P450 enzyme 2D6, and can lead to increased blood levels of lidocaine, beta blockers, opioids, and some antidepressants. Quinidine also inhibits the transport protein P-glycoprotein and so can cause some peripherally acting drugs such as loperamide to have central nervous system side effects, such as respiratory depression, if the two drugs are coadministered. Quinidine can cause thrombocytopenia, granulomatous hepatitis, myasthenia gravis, and torsades de pointes, so is not used much today. Quinidine-induced thrombocytopenia (low platelet count) is mediated by the immune system, and may lead to thrombocytic purpura. Quinidine intoxication can lead to a collection of symptoms collectively known as cinchonism, with tinnitus (ringing in the ears) being among the most characteristic and common symptoms of this toxicity syndrome. Quinidine toxicity can also invoke episodes of Torsades de Pointes - a rapid and dangerous ventricular rhythm. This means at higher heart rates, the block increases, while at lower heart rates, the block decreases.

Diabetic foot ulcers account for five percent of these ulcers and 50 to 80 percent of all lower-extremity amputations. Optimal conventional treatments for chronic wounds are based on the concepts of wound bed preparation, which include eliminating necrotic tissue and fibrinous exudate, controlling infection, establishing moisture balance, and optimizing the epidermal margin. However, despite applying the principles of wound bed preparation, some chronic wounds fail to heal in a timely fashion and are candidates for advanced interventions, including topical growth factors,[3,4] bioengineered skin substitutes, or surgical intervention for closure. Although advanced technologies have been proven to be effective in controlled clinical studies, they are expensive and are not universally available to all patients. Thus, there is a need for an inexpensive, readily available, simple therapy that can be added to the concept of wound bed preparation. Multiple studies have established that the molecular and cellular environments of chronic skin wounds differ dramatically from the acute wound environment. In general, chronic wounds typically contain increased levels of pro-inflammatory cytokines and increased levels of proteases that are able to degrade essential mitogenic factors.[6–9] These observations led to the hypothesis that correcting these molecular abnormalities would promote healing of chronic wounds. Studies from Trengove and colleagues support this hypothesis by demonstrating that elevated levels of pro-inflammatory cytokines and proteases decreased in chronic venous stasis ulcers as healing progressed. These results suggest that an inexpensive, simple-to-administer, topical agent that reduced inflammation and protease activities might be an effective adjunctive therapy for wound bed preparation.
