Ranitidine, a histamine H2-receptor antagonist, is now well established as a potent inhibitor of gastric acid secretion effective in the treatment and prophylaxis of gastrointestinal lesions aggravated by gastric acid secretion.
Famotidine, a competitive histamine H2-receptor antagonist, is used to treat gastrointestinal disorders such as gastric or duodenal ulcer, gastroesophageal reflux disease, and pathological hypersecretory conditions. Famotidine inhibits many of the isoenzymes of the hepatic CYP450 enzyme system. Other actions of Famotidine include an increase in gastric bacterial flora such as nitrate-reducing organisms. Famotidine binds competitively to H2-receptors located on the basolateral membrane of the parietal cell, blocking histamine affects. This competitive inhibition results in reduced basal and nocturnal gastric acid secretion and a reduction in gastric volume, acidity, and amount of gastric acid released in response to stimuli including food, caffeine, insulin, betazole, or pentagastrin.

Potassium citrate is indicated for the management of renal tubular acidosis with calcium stones, hypocitraturic calcium oxalate nephrolithiasis of any etiology, uric acid lithiasis with or without calcium stones. WhenPotassium citrate is given orally, the metabolism of absorbed citrate produces an alkaline load. The induced alkaline load in turn increases urinary pH and raises urinary citrate by augmenting citrate clearance without measurably altering ultrafilterable serum citrate. Thus, potassium citrate therapy appears to increase urinary citrate principally by modifying the renal handling of citrate, rather than by increasing the filtered load of citrate. Potassium citrate is used as a food additive (E 332) to regulate acidity.

Bibrocathol (trade names Noviform and Posiformin) is a well-established topical antiseptic for the treatment of acute eyelid diseases like blepharitis. Eye ointments containing 2 or 5 % bibrocathol and the excipients liquid paraffin, white soft paraffin, and lanolin have been marketed since 1967 for the treatment of eye irritation, chronic blepharitis, and uninfected corneal injuries. Reports of clinical experience with bibrocathol for inflammation of the edge of the palpebra exist since the beginning of the 20th century. Until recently, no controlled, randomized clinical studies according to the guidelines for Good Clinical Practice for Trials on Medical Products for Human Use (GCP) as defined by the International Conference on Harmonisation (ICH) have been performed with bibrocathol 2 % ointment, as these were not required for marketing authorization in the 1960s. A first double-blind, prospective, controlled, GCP-compliant clinical study was recently performed to assess the efficacy of bibrocathol 5 % (Noviform®) in acute blepharitis. It demonstrated superior efficacy of bibrocathol 5 % ointment as compared to an ointment vehicle (placebo) after 2 weeks of treatment as assessed by a combined measure of slit-lamp examination results and patients’ subjective complaints.
