How do agonists cause tolerance
WebIn clinical practice, the most common side effects of GLP-1RAs are gastrointestinal (GI), typically including upper-GI effects (e.g. nausea or vomiting) and/or lower-GI effects (diarrhea or constipation). These GI adverse effects appear to be dose-dependent and are likely a class effect [ 1, 9 ]. WebShort-acting β-agonist (SABA) drugs have been mainstays of asthma therapy for many decades and are recommended treatment at all levels of asthma severity, as they provide prompt relief of asthma symptoms through smooth muscle relaxation and, thereby, bronchodilatation. At all levels of asthma severity more severe than mild intermittent, …

WebNov 7, 2008 · Pharmacodynamic tolerance occurs when the intrinsic responsivity of the receptor system diminishes over time. Acute tolerance is mediated predominantly by pharmacodynamic mechanisms, manifested as a decreased response following a single administration of the agent or during repeat-dosing but over a short time frame. WebIt has been demonstrated that the degree of agonist-induced desensitization of the β 2-adrenoceptor is related to agonist efficacy (strength of signalling), whereby high-efficacy agonists (e.g. formoterol) cause more phosphorylation and internalization of the receptor than low-efficacy agonists (e.g. salmeterol).These early studies, however, used a protocol …
