It is also important to check incompatibilities of the last years to spare the patient unneces- sary side effects and dangerous re-exposure erectafil 20mg overnight delivery erectile dysfunction pump manufacturers. Some pilot studies reported success when only new drugs are used erectafil 20mg with amex erectile dysfunction exam what to expect. In the French TRIO study, 103 extensively pretreated patients with TCF were treated with RAL+ETV+MVC, out of which 86% achieved plasma viremia below 50 copies/ml at 48 weeks (Yazdanpanah 2009). In a smaller Italian study with 28 patients on the same combination RAL+ETV+MVC, this got to 96% after 4 years (Nozza 2014). Before switching, physicians should go over the classes, one by one, depending on the individual resistance profile, even the old ones. Consider AZT and TDF simultaneously, due to diverging resistance pathways NNRTIs At <3 NNRTI mutations, consider etravirine (approved only with a boosted PI/r), otherwise discontinue NNRTIs PIs Darunavir/r (good data with etravirine) or tipranavir/r Maraviroc Tropism test? Due to non-detected dual-tropic viruses, use 2 definitively active agents such as raltegravir and T-20 (if nothing else works), remember dose adaptions when boosting with PIs INSTIs At least 1–2 active agents additionally needed, be aware of rapid resistance development, dolutegravir most potent T-20 Consider when uncertain that at least one other agent beyond dolutegravir or maraviroc is active NRTIs: Even if 3TC or FTC are no longer effective according to the resistance test, it might make sense in many cases to continue treatment with them. In this way, HIV is forced to conserve the M184V mutation, which reduces the replication fitness (Eron 2004, Campbell 2005, Castagna 2006). Due to diverging resistance pathways, another consideration may be to use AZT and TDF. This also applies when patients have already been treated with these agents. By adding AZT, viral load can be decreased to below detection in the presence of resensitizing K65R (Stephan 2010). However, recent studies evaluating if partially active or inactive NRTIs contribute to treatment response have yielded conflicting results (Imaz 2011, Scherrer 2011). NNRTIs: In the case of NNRTIs, with less than three NNRTI resistance mutations, etravirine seems to be a good option in combination with a boosted PI (most effec- tive with darunavir/r). In other cases it is recommended to discontinue NNRTIs. There is little doubt that once generated, resistance remains. However, with preg- nant women who have received nevirapine once for transmission prophylaxis there was no elevated rate of treatment failure on nevirapine-containing regimens if ART was initiated more than 6 months after delivery – at least theoretically, it seems pos- sible for NNRTI resistances to disappear provided one waits a long enough time (Lockman 2007). However, there is no other data on recycling NNRTIs besides those for transmission prophylaxis. PIs: In the case of PIs, the boosted PIs darunavir and tipranavir are strongly recom- mended. These PIs probably have distinct resistance profiles. When resistance find- ings are unclear, they should be discussed with the virologist. If darunavir/r and tipranavir/r are not available or if they are not tolerated, one can try lopinavir/r; other PIs are probably not suitable. INSTIs: in patients naïve to INSTIs, all three agents, namely raltegravir, elvitegravir and dolutegravir can be considered. If INSTI RAMs are already present, sequencing of raltegravir and elvitegravir makes no sense (DeJesus 2007, Garrido 2012). The VIKING trials have shown that higher doses of dolutegravir (50 mg BID instead of 50 mg QD) may help to overcome raltegravir resistance. In VIKING III, a single-arm, open-label phase III study in which therapy-experienced patients with INSTI-resistant virus received DTG 50 mg BID while continuing their failing regimen (without raltegravir or elvitegravir), viral load 228 ART declined by 1. In total, 69% of the patients achieved <50 copies/ml at week 24 (Castagna 2014), an exceptional results in this patient population. There is no doubt that dolutegravir should be considered in any patient with multiple RAMs. Maraviroc, T-20: If at least one other agent is still active, it seems sufficient to treat with only one of the new agents, either maraviroc or an INSTI, to reduce the viral load to below the limit of detection. That way, one could keep the option with the other drug that could be then combined with T-20 in the future. In the case of maraviroc, a recent tropism test should be available. If maraviroc and INSTIs are the only active agents according to the resistance test, they could and should be admin- istered together.

A pilot study of oral sumatriptan as intermittent prophylaxis of menstruation-related migraine. Triptans Page 54 of 80 Final Report Update 4 Drug Effectiveness Review Project Appendix A. Glossary This glossary defines terms as they are used in reports produced by the Drug Effectiveness Review Project. Some definitions may vary slightly from other published definitions. Absolute risk: The probability or chance that a person will have a medical event. It is the ratio of the number of people who have a medical event divided by all of the people who could have the event because of their medical condition. Add-on therapy: An additional treatment used in conjunction with the primary or initial treatment. Adherence: Following the course of treatment proscribed by a study protocol. Adverse drug reaction: An adverse effect specifically associated with a drug. Adverse event: A harmful or undesirable outcome that occurs during or after the use of a drug or intervention but is not necessarily caused by it. Adverse effect: An adverse event for which the causal relation between the intervention and the event is at least a reasonable possibility. Active-control trial: A trial comparing a drug in a particular class or group with a drug outside of that class or group. Allocation concealment: The process by which the person determining randomization is blinded to a study participant’s group allocation. Applicability: see External Validity Before-after study: A type nonrandomized study where data are collected before and after patients receive an intervention. Before-after studies can have a single arm or can include a control group. Bias: A systematic error or deviation in results or inferences from the truth. Several types of bias can appear in published trials, including selection bias, performance bias, detection bias, and reporting bias. Bioequivalence: Drug products that contain the same compound in the same amount that meet current official standards, that, when administered to the same person in the same dosage regimen result in equivalent concentrations of drug in blood and tissue. Black box warning: A type of warning that appears on the package insert for prescription drugs that may cause serious adverse effects. It is so named for the black border that usually surrounds the text of the warning. A black box warning means that medical studies indicate that the drug carries a significant risk of serious or even life-threatening adverse effects. The US Food and Drug Administration (FDA) can require a pharmaceutical company to place a black box warning on the labeling of a prescription drug, or in literature describing it. A way of making sure that the people involved in a research study — participants, clinicians, or researchers —do not know which participants are assigned to each study group. Blinding usually is used in research studies that compare two or more types of treatment for an illness. Case series: A study reporting observations on a series of patients receiving the same intervention with no control group. Case study: A study reporting observations on a single patient. Case-control study: A study that compares people with a specific disease or outcome of interest (cases) to people from the same population without that disease or outcome (controls). Clinical diversity: Differences between studies in key characteristics of the participants, interventions or outcome measures. Clinically significant: A result that is large enough to affect a patient’s disease state in a manner that is noticeable to the patient and/or a caregiver. Cohort study: An observational study in which a defined group of people (the cohort) is followed over time and compared with a group of people who were exposed or not exposed to a particular intervention or other factor of interest.
