This paper is being passed around the Lyme disease patient community that has everyone's attention. It's about the most effective timing and the use of one 200 mg capsule of doxycycline as prophylaxis to prevent Lyme disease after a tick bite. The bottom line from the authors of the study: One 200 mg capsule of doxycycline is totally ineffective in preventing Lyme disease if it is administered 48 hours after a tick bite. And even if administered in less than 48 hours, it is no guarantee of successfully preventing infection. Elizabeth Maloney: Since 2001 the IDSA has been recommending preventive treatment of a single dose of doxycyline for tickbites under certain narrow conditions. have just published a new article concluding that if the treatment is given as little as 24 hours after the bite, only 47% of the mice were cured. Piesman also concludes that "Prophylactic treatment was totally ineffective when delivered ≥2days (48hrs) after tick removal." The IDSA recommends treating if: "If the person meets ALL of the above criteria, the recommended dose of doxycycline is a single dose of 200 mg for adults and 4 mg/kg, up to a maximum dose of 200 mg, in children ≥ 8 years" In 2004 Zeidner et al.

Dolan MC, Zeidner NS, Gabitzsch E, Dietrich G, Borchert JN, Poché RM, Piesman J. Although this excellent clinical trial provided much needed information, the authors enrolled subjects if the tick bite occurred within 3days of their clinical visit, but did not analyze the data based on the exact time between tick removal and delivery of prophylaxis. Abstract The prophylactic and curative potential of doxycycline hyclate formulated in a rodent bait at concentrations of 250 and 500 mg/Kg was evaluated in a murine model of Lyme borreliosis. An animal model allows for controlled experiments designed to determine the point in time after tick bite when delivery of oral antibiotics would be too late to prevent infection with B. Accordingly, we developed a tick-bite prophylaxis model in mice that gave a level of prophylactic protection similar to what had been observed in clinical trials and then varied the time post tick bite of antibiotic delivery. doxycycline blood pressure This study was conducted to examine the pharmacokinetics of doxycycline in nine healthy volunteers who had fasted overnight. Simultaneous ingestion of milk diminished the peak plasma concentration by 24% and the absorption by 9–53% (mean 30%). The subjects swallowed the antibiotic capsules with 300 ml of water or 300 ml of fresh milk. It is concluded that, like the other tetracyclines, doxycycline should not be administered together with milk. In einem Cross-over-Versuch erhielten neun Probanden präprandial je 200 mg Doxycyclin oral in Gelatinekapseln appliziert. Als Einnahmegetränk dienten entweder 300 ml Wasser oder Milch. Bei der Applikation mit Milch wurden die Blutspiegelmaxima durchschnittlich um 24% gesenkt, und die Absorptionsquoten wurden um 9–53% (durchschnittlich um 30%) vermindert. Daraus muß der Schluß gezogen werden, auch Doxycyclin — wie alle anderen Tetracycline — nicht mit Milch einzunehmen.

In dieser Studie wurde untersucht, welchen Schutz eine Antibiotika-Einmaldosis bietet. Methoden Die Studie wurde im US-Bundesstaat New York durchgeführt, in einer Region, wo die Zecken stark borrelienbefallen sind. Personen, die einen Zeckenstich erlitten hatten, der höchstens drei Tage zurücklag und die keine Symptome einer Borreliose aufwiesen, wurden zwischen 19 in die Studie aufgenommen. Bei allen Personen wurde eine Borrelien-Serologie durchgeführt. Danach erhielten die Studienteilnehmerinnen und -teilnehmer doppelblind eine Einmaldosis von 200 mg Doxycyclin (Vibramycin® u.a.) oder Placebo. Ergebnisse 482 Personen wurden in die Auswertung miteinbezogen; 28 von ihnen waren von mehr als nur einer Zecke gestochen worden. In der Doxycyclin-Gruppe entwickelte sich während der 6wöchigen Beobachtungszeit bei nur 1 von 235 Personen im Bereich der Stichstelle ein Erythema migrans (0,4%), in der Placebo-Gruppe bei 8 von 247 (3,2%). Doxycycline is an antibacterial drug of semi-synthetic origin, which belongs to the tetracycline series of antibiotics.
