Aim:
Patient-reported outcomes associated with adverse events (AEs) reported with generics have not been evaluated. To map AEs associated with generics to the NIH Patient-reported Outcomes Measurement Information System.
Methods:
We mapped 381 AEs from 148 case reports of generic tamsulosin, levothyroxine and amphetamine/dextroamphetamine to the physical, mental and social domain of the NIH Patient-Reported Outcomes Measurement Information System after reviewing 1237 case reports in the US FDA's Adverse Event Reporting System (FAERS; 2011-2013).
Results:
75%, 76% and 71% reports were classified under the physical domain for tamsulosin, levothyroxine and amphetamine/dextroamphetamine, while 9%, 9% and 18% reports were classified under the mental domain, respectively.
Conclusion:
FAERS reveals several domains of patient-relevant concerns associated with generic drugs.

This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

01:28Adrenergic Agonists: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...

01:30Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Vasopressor or pressor agents: They increase blood pressure and function as cardiac stimulants. Examples include endogenous catecholamines (norepinephrine and dopamine) and synthetic agents (phenylephrine).
Bronchodilators: β2-agonists can relax bronchial muscles and widen airways. They are commonly used for treating obstructive pulmonary...
