    Notes: Summary Three doses (3 mg, 6 mg and 12 mg) of piretanide, a new high ceiling diuretic, and placebo were given to 8 volunteers to investigate the relationship between the pharmacodynamic parameters, the dose and its urinary excretion. Intake of food and fluid were standardized from 48 h before until 24 h after drug administration. Urinary output, excretion of unchanged drug, and the excretion and clearance of Na+ and K+ were measured hourly for 7 h after treatment. A clear dose-response relationship was found for cumulative urinary output, cumulative excretion of Na+ and K+, clearance of Na+ and K+ and the urinary sodium/potassium ratio. A significant correlation was found between the net urine volume and the excretion of piretanide per time interval. The clearances of Na+ and K+ were significantly correlated with the excretion of piretanide. Clearance values correlated well with corresponding urine volumes.

    Notes: Summary The influence of experimental rhinitis on the absorption of buserelin, measured as the serum luteinizing hormone (LH) response, has been investigated. A single dose of 200 µg buserelin was given to 24 healthy male volunteers after induction of experimental rhinitis with histamine and after use of a saline spray (placebo control). Except on one occasion, when the pump-spray apparently was incorrectly operated, serum LH concentration rose after buserelin. There was no difference in the LH response between histamine-induced rhinitis and saline controls. It was concluded that intranasal application of buserelin represents a reliable mode of application and that modification of the administration route or a change in the dosage schedule during naturally-occurring nasal inflammations, such as the common cold and allergic rhinitis, is unnecessary in patients undergoing chronic treatment with intranasal buserelin, e.g. for prostatic cancer, endometriosis, precocious puberty, and contraception.
