Prednisolone is a synthetic pregnane corticosteroid closely related to its cognate prednisone, having identical structure save for two fewer hydrogens near C 11. It is also known as δ 1-cortisol, δ 1-hydrocortisone, 1,2-dehydrocortisol, or 1,2-dehydrohydrocortisone, as well as 11β,17α,21-trihydroxypregna-1,4-diene-3,20-dione. [50] [51]
Kindling refers to the phenomenon of increasingly severe withdrawal symptoms, including an increased risk of seizures, that occurs as a result of repeated withdrawal from alcohol or other sedative–hypnotics with related modes of action. Ethanol (alcohol) has a very similar mechanism of tolerance and withdrawal to benzodiazepines, involving ...
Thus, there remains lingering doubt about the mechanisms of ethanol listed here, even for the GABA A receptor, the most-studied mechanism. [24] In the past, alcohol was believed to be a non-specific pharmacological agent affecting many neurotransmitter systems in the brain, [25] but progress has been made over the last few decades.
However, homeostatis does not explain how tolerance influences alcohol addiction in many cases. Epigenetic alterations, including phosphorylation, methylation, acetylation, miRNA, and chromatin remodeling, may help explain the cases not explained by homeostatic mechanisms. These epigenetic mechanisms have been studied in rodents.
Lower rates were reported for opioid– (12% (8 – 18%)), alcohol– (9% (6 – 15%)) and sedative– (10% (7 – 15%)) induced psychoses. Transition rates were slightly lower in older cohorts but were not affected by sex, country of the study, hospital or community location, urban or rural setting, diagnostic methods, or duration of follow-up.
Alcohol dependence refers to an entity in which only alcohol is the involved addictive agent. Alcoholism refers to an entity in which alcohol or any cross-tolerant addictive agent is involved. In alcohol dependence, reduction of alcohol, as defined within DSM-IV, can be attained by learning to control the use of alcohol.
Prednisone is a glucocorticoid medication mostly used to suppress the immune system and decrease inflammation in conditions such as asthma, COPD, and rheumatologic diseases. [3] It is also used to treat high blood calcium due to cancer and adrenal insufficiency along with other steroids . [ 3 ]
Alcohol (from Arabic al-kuḥl 'the kohl'), [11] sometimes referred to by the chemical name ethanol, is the second most consumed psychoactive drug globally behind caffeine. [12] Alcohol is a central nervous system (CNS) depressant, decreasing electrical activity of neurons in the brain. [13]
