Medicines Doxycycline

Tetracyclines are produced by various Streptomyces strains and are extensively applied in human and veterinary medicine. They display a broad spectrum of antimicrobial activity in combination with low toxicity and can be applied orally. The most commonly prescribed tetracycline drugs are tetracycline itself and oxytetracycline, an oxygenated derivative, which are directly isolated from fermentation liquors, and doxycycline whose partial synthesis from oxy-... 

Any side effect that forces you not to take your medicine is serious enough that you should consult or see your doctor. Serious side effects of ciprofloxacin include seizures, mental confusion, rash that does not go away, or excessive diarrhea. If you have any of these effects, call your doctor.

An active substance, although initially released from its dosage form (and dissolved), may become unavailable for absorption due to reactimis with other medicines or food components [4]. An example is the formation of insoluble complexes of tetracycline with calcium or aluminium ions from antacids or milk products. Interaction (chelation or binding) with iron ions leads to a reduced absorption for a variety of active substances such as doxycycline, penicillamine, methyldopa and ciprofloxacin. The absorption of active substances showing pH-dependent dissolution behaviour may be influenced by medicines that influence the gastric pH, such as H2-antagonists, proton pump inhibitors and antacids. Antimycotic active substances such as ketoconazole or itraconazole dissolve better in acidic fluids. Therefore their bioavailability may be increased by the concomitant use of an acidic drink like cola, whereas the concomitant use of antacids or proton pump inhibitors is likely to reduce the bioavailability. Concomitant use of milk may increase the dissolution of acidic active substances, whereas fats from food may increase the bioavailability of lipophilic active substances like albendazole and griseofulvin. 

The oesophagus has only a transport function for active substances. It is important, however, that corroding and irritating active substances, like doxycycline and bisphosphonates, do not stick in the oesophagus as they can damage the tissue and cause ulcerations. Ample water should be taken when swallowing such medicinal products. 

PGDs are documents which make it legal for medicines to be given to groups of patients, for example in a mass casualty situation, without an individual prescription having to be written for each patient. They can also be used to empower staff other than doctors (for example paramedics and nurses) to give the medicine in question legally. Examples include ciprofloxacin, doxycycline and potassium iodate.
