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.
Drugs are researched for their physiochemical properties, physical side effects, and psychological side effects. Researchers in psychopharmacology study a variety of different psychoactive substances, including alcohol, cannabinoids, club drugs , psychedelics, opiates, nicotine , caffeine , psychomotor stimulants , inhalants , and anabolic ...
These side effects are serious and some of them are permanent, and many remain a crucial concern for companies and healthcare professionals and substantial efforts are being encouraged to reduce the potential risks for future antipsychotics through more clinical trials and drug development.
Certain drugs, most famously the pesticide and metabolite MPP+ (1-methyl-4-phenylpyridin-1-ium) can induce Parkinson's disease by destroying dopaminergic neurons in the substantia nigra. [11] MPP+ interacts with the electron transport chain in the mitochondria to generate reactive oxygen species which cause generalized oxidative damage and ...
There are many types of drugs, legal and illegal, that affect dopamine and its interactions in the brain. With Parkinson's disease, a disease that decreases the amount of dopamine in the brain, the dopamine precursor Levodopa is given to the patient due to the fact that dopamine cannot cross the blood–brain barrier and L-dopa can. Some ...
Medications are used to reverse the symptoms of extrapyramidal side effects caused by antipsychotics or other drugs, by either directly or indirectly increasing dopaminergic neurotransmission. The treatment varies by the type of the EPS, but may involve anticholinergic agents such as procyclidine, benztropine, diphenhydramine, and trihexyphenidyl.
GLP-1 drugs used for weight loss involve all kinds of side effects—good and not-so-good—that may or may not strike the average user. (Reminder that there are many of these meds now.
Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
