Spironolactone has been identified as an inhibitor of NRG1‐ERBB4 signaling. [142] Spironolactone has been found to act as a potent inhibitor of the pannexin 1 channel, and this action appears to be involved in its antihypertensive effects independently of MR antagonism. [143] Spironolactone has been found to block hERG channels. [144]
[107] [109] [134] Spironolactone is a prodrug, so most of its actions are actually mediated by its various active metabolites. [107] The major active forms of spironolactone are 7α-thiomethylspironolactone (7α-TMS) and canrenone (7α-desthioacetyl-δ 6 -spironolactone).
A box of Lorazepam Orion (Lorazepam) tablets. Lorazepam, sold under the brand name Ativan among others, is a benzodiazepine medication. [14] It is used to treat anxiety (including anxiety disorders), trouble sleeping, severe agitation, active seizures including status epilepticus, alcohol withdrawal, and chemotherapy-induced nausea and vomiting.

Midazolam is the most commonly prescribed for this use because of its strong sedative actions and fast recovery time, as well as its water solubility, which reduces pain upon injection. Diazepam and lorazepam are sometimes used. Lorazepam has particularly marked amnesic properties that may make it more effective when amnesia is the desired effect.
[113] [114] Long-term use of benzodiazepines in the elderly can lead to a pharmacological syndrome with symptoms including drowsiness, ataxia, fatigue, confusion, weakness, dizziness, vertigo, syncope, reversible dementia, depression, impairment of intellect, psychomotor and sexual dysfunction, agitation, auditory and visual hallucinations ...
Spironolactone is a prodrug with a short terminal half-life of 1.4 hours. [5] [6] [7] The active metabolites of spironolactone have extended terminal half-lives of 13.8 hours for 7α-TMS, 15.0 hours for 6β-OH-7α-TMS, and 16.5 hours for canrenone, and accordingly, these metabolites are responsible for the therapeutic effects of the drug.

The action of drugs on the human body (or any other organism's body) is called pharmacodynamics, and the body's response to drugs is called pharmacokinetics. The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way.
