There are both external causes of damage, including infection, and ototoxic drugs, as well as intrinsic causes, including genetic mutations. A common cause or exacerbating factor in SNHL is prolonged exposure to environmental noise, or noise-induced hearing loss. Exposure to a single very loud noise such as a gun shot or bomb blast can cause ...
In this article, we’re taking a closer look at sensorineural hearing loss (SNHL) is, its causes, and potential treatments.
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
Most drugs and procedures have a multitude of reported adverse side effects; the information leaflets provided with virtually all drugs list possible side effects. Beneficial side effects are less common; some examples, in many cases of side-effects that ultimately gained regulatory approval as intended effects, are:
Side effects attributed to propafenone include hypersensitivity reactions, lupus-like syndrome, agranulocytosis, CNS disturbances such as dizziness, lightheadedness, gastrointestinal upset, a metallic taste and bronchospasm. About 20% of patients discontinued the drug due to side effects.
Many of these symptoms may be side effects of the drug or drug interaction causing excessive levels of serotonin rather than an effect of elevated serotonin itself. Tremor is a common side effect of MDMA's action on dopamine, whereas hyperreflexia is symptomatic of exposure to serotonin agonists.
A number of non-SSRI drugs are not associated with sexual side effects (such as bupropion, mirtazapine, tianeptine, agomelatine, tranylcypromine, and moclobemide [57] [58] [59]). Several studies have suggested that SSRIs may adversely affect semen quality. [60] [61]
For example, clinical trial data shows that the newer-generation ED medication avanafil (sold as Stendra) is less likely to cause headaches, flushing and other side effects than older ED drugs ...
