Theophylline
The dosage of the other diabetes drug may have to be reduced.
After you begin taking aminophylline, oxtriphylline, or theophylline, it is very important that your doctor check the level of medicine in your blood at regular intervals to find out if your dose needs to be changed.
6. Discontinuation The most common reason women discontinue DMPA is a change in the menstrual cycle. 7. Special issues Breastfeeding. Although non-hormonal methods are generally preferable during breastfeeding, progestin-only hormonal methods may be appropriate if initiated after breastfeeding is well established usually after 6 weeks ; . POPs, in conjunction with full breastfeeding usually first 6 months ; , provide excellent contraceptive coverage at less cost than injectables. Young women. Low pregnancy rate, reversibility, and privacy make DMPA an attractive option for.

The trial design was parallel, prospective, randomized, placebo controlled, and single blinded. It was performed after the approval of the local institutional ethic committee review board of the Eberhard-Karls University of Tubingen. Written informed consent was given by each patient before study inclusion. The study followed the Declaration of Helsinki and good clinical practice guidelines. Patients who had various types of cancer and were allocated to cisplatin-based combination chemotherapy and had normal renal function measured by creatinine clearance 60 ml min ; were eligible for the trial. Other eligibility criteria included age 18 yr, predicted life expectancy 2 mo, Karnofsky status 60%, and adequate baseline organ functions. Patients were excluded when they had received previous treatment with aminophylline derivatives immediately before study entry; had an uncontrolled coronary heart disease, angina pectoris, arrhythmia, hyperthyroidism, acute infection, bilateral loss of hearing II according to World Health Organization criteria, sensory peripheral neuropathy, known adverse events in association with theophylline; or were pregnant and lactating or noncompliant.

Children in particular are vulnerable to serious drug interactions where the prescriber forgets to enquire about current medication. The influence of hypericum on the pharmacokinetics of digoxin A single-blind, placebo controlled study investigated the influence of single and multiple dose co-medication of Hypericum extract LI160 900mg ; on the steady state pharmacokinetics of digoxin in 25 healthy volunteers.44 The study reported that after 10 days of treatment with Hypericum extract, a 25% decrease in digoxin blood levels was observed. A 9% decrease in digoxin levels in the placebo group was also seen, it was suggested this may reflect known variability in digoxin distribution or systemic availability. The study reported that although preliminary in vitro studies have suggested that the hypericins may induce CYP enzymes, oxidative hepatic metabolism only plays a minor role in the elimination of digoxin. Degradation of digoxin is determined partly by gastric acid secretions and other factors are involved. Intestinal absorption, brain distribution and renal tubular secretion of digoxin are mediated by the multiple drug resistant gene product P-glycoprotein. The study suggests that the reduction in digoxin observed might be due to an affect of Hypericum on the P-glycoprotein as opposed to an affect on CYP enzymes. Drug interactions with digoxin do occur because it has a narrow therapeutic window and monitoring of elderly patients by GPs can be inconsistent. Tbeophylline Theophylline is metabolized by CYP1A2. A recent case study discussed a woman of 42 who had had to take increasing doses of th3ophylline to achieve the desired therapeutic plasma levels. She noted that, two months previously, she had started taking Hypericum 300mg 0.3% hypericin ; daily. The case is hard to evaluate as she was taking eleven other prescribed drugs, with varying effects on CYP, and smoked half a pack of 34 . Canadian Journal of Herbalism cigarettes daily. However, on stopping Hypericum her 5heophylline plasma levels rose markedly within seven days and her dosage was reduced.45 The authors suggest that induction of CYP1A2 by hypericin may have been responsible. Selective serotonin re-uptake inhibitiors E Ernst published an article in The Lancet, December 99, stating that "the mode of action for Hypericum extracts is thought to be similar to that of conventional serotonin re-uptake inhibitors".46 He goes on to say that results demonstrated Hypericum to exhibit "strong" SSRI activity. However the study to which Ernst refers, states that Hypericum shows affinity to three different neurotransmitter transporter systems, serotonin, dopamine and norepinephrine, and points to a unique and as yet unknown mechanism of action, unlike conventional antidepressant drugs.47 The study discusses current findings indicating that Hypericum extract, in contrast to tricyclic antidepressants TCAs ; or specific serotonin re-uptake inhibitors SSRIs ; , does not show the same affinity for the 5-HT2-receptor of the serotonin transporter system in vitro.48 Other in vitro studies have reported Hypericum extracts to exhibit activity on several neurotransmitters, however, the activities found are thought to be too weak to fully account for the antidepressant action of Hypericum.49, 50, 51 Experiments have used crude homogenates of frontal brain cortex of rats for synaptosomal uptake assays. One should, in any case, question whether results of such experiments can be directly extrapolated to humans taking oral doses of Hypericum. A recently published report from a New York hospital reported 5 cases of elderly patients possibly having adverse reactions from taking sertraline SSRI ; and one taking nefazodone for depressive symptoms in conjunction with standardised Hypericum extracts.52 The adverse reactions documented included nausea, epigastric pain, restlessness, irritability and anxiety. The report suggested that these symptoms are indicative of serotonin syndrome. After stopping all medication the symptoms subsided in all subjects within a few days. Two patients received cyproheptadinen to treat serotonin syndrome. There needs to be consideration of possible. Butter, cream, margarine or milk, where they have been adulterated or impoverished.
