The antihistaminic effect of loratadine (160 mg) was compared in twenty-four normal male volunteers to chlorpheniramine maleate (4 mg) and placebo in a double blinded 3-way cross-over study of latin square design. After receiving single oral doses of each medication, the wheal response to serial 0.1 ml intradermal histamine (2 micrograms) and saline(More)
The influence of diurnal variation and morbid obesity on the morphine requirements of patients using patient-controlled analgesia (PCA) was studied. Forty-six patients undergoing either elective (Group I) or gastric bypass (Group II) surgery composed the study group. Patients were allowed to use the PCA machine for 36 to 72 hours postoperatively to deliver(More)
Patient-controlled analgesia is a relatively new method of administering intravenous narcotics for postoperative pain relief. The technique involves the self-administration of a given analgesic in a bolus dose with the aid of a timed infusion and sequencing device. Ten morbidity obese patients undergoing elective gastric bypass surgery were treated in a(More)
In postoperative patients using patient-controlled analgesia (PCA) to administer i.v. doses of morphine sulfate, respiratory rates and subjective rankings of pain, sedation, and liking for the drug were correlated with plasma morphine concentrations. In 12 patients selected before surgery, the initial morphine sulfate dose of 0.6 mg/sq m was increased or(More)
Nifedipine kinetics have not been described in clinically relevant detail because of difficulties in formulating a stable preparation for intravenous use and lack of a specific and sensitive assay for plasma nifedipine. We recently developed a gas-chromatographic method and determined conditions in which nifedipine could be protected from photodegradation.(More)
This report concerns evaluation of patient-controlled analgesia (PCA) in the form of two preliminary investigations. In the first study, the patient-controlled analgesia device, which consists of a pump linked to a timer so that patients can activate intravenous administration of morphine sulfate to themselves during the postoperative period, was used in(More)
The influence of a standard meal on the extent and rate of absorption of pseudoephedrine from a controlled-release (CR) capsule formulation (Pennkinetic System) was studied in 16 normal male volunteers. Equivalent single doses of an immediate-release (IR) pseudoephedrine reference syrup and the CR capsules were each studied under both fasted and(More)
