A new doxycycline formulation consisting of enteric-coated doxycycline hyclate pellets in capsules is aimed at reducing gastrointestinal adverse reactions related to doxycycline therapy. In this randomised, double-blind, 3-way crossover study, adverse reactions caused by short term treatment with enteric-coated doxycycline hyclate pellets in capsules were compared with placebo and doxycycline monohydrate tablets. The latter are generally considered to be better tolerated than older formulations of doxycycline hyclate. They were given 150mg of doxycycline once daily over 3 consecutive days with a washout of 4 to 10 days between the study periods. The medication was administered after an overnight fast (10 hours) with 200ml of tap water. An upright position was maintained for 1 hour and no food was allowed for 2 hours after drug administration. Adverse reactions were reported by 66% of the subjects during treatment with doxycycline monohydrate, while 43% reported adverse reactions during treatment with enteric-coated doxycycline hyclate and 30% during placebo. Compared with the 2 other groups, doxycycline monohydrate caused significantly more adverse reactions in general, and abdominal pain, nausea and vomiting in particular. It is concluded that enteric-coated doxycycline hyclate pellets in capsules have significantly better gastrointestinal tolerability compared with doxycycline monohydrate. Are there any major differences between doxycycline monohydrate and doxy hyclate? Many patients wind up with GI side effects and call in stating they can’t tolerate the medicine. Which form of doxy is more appropriate for skin conditions like cystic acne/etc? This question is fitting for a student pharmacist to answer. This week I’ll turn over Clinicians Corner to Zethan Koch who is doing the Rural Pharmacy Rotation at Thompson Pharmacy on Broad Avenue. Zethan is a Pharm D candidate from D’Youville College School of Pharmacy in Buffalo, New York. Background: Let’s begin with a history lesson and then explain how the drug works. Doxycline is a semisynthetic tetracycline that was synthesized in the early 1960s by Charles Stephens, a researcher for Pfizer.
If these effects are mild, they may go away within a few days or a couple of weeks. If they’re more severe or don’t go away, talk to your doctor or pharmacist. Call your doctor right away if you have serious side effects. Call 911 if your symptoms feel life-threatening or if you think you’re having a medical emergency. Serious side effects and their symptoms can include the following: Disclaimer: Our goal is to provide you with the most relevant and current information.
