Psychomotor skills during subacute treatment with thioridazine and bromazepam, and their combined effects with alcohol

Annals of Clinical Research

Twenty paid healthy students volunteered for a doubleblind cross-over trial on the effects of two weeks' treatment with placebo, thioridazine and bromazepam on psychomotor skills. The doses used were thioridazine 10 mg t.i.d. during the first week and 20 mg t.i.d. during the second week, or 6 mg of bromazepam t.i.d. during two weeks choice reaction test, two co-ordination tests, a divided attention test, flicker fusion, and proprioception tests were used. The psychomotor skills were measured in the afternoon of the 7th and 14th day of each treatment, 30, 90 and 150 minutes after the second daily administration of the drug in combination with either an alcoholic or a placebo drink. There were no significant differences between the test weeks. Thioridazine alone resembled placebo and had no major combined effect with alcohol. Bromazepam impaired reactive and co-ordinative skills and attention deteriorated. The combination of bromazepam and alcohol potentiated the deterious effects of the single agents, and this effect was most remarkable at 30 minutes. The subjects also gave exaggerated responses in the proprioceptive tests. No significant alterations were recorded in the flicker fusion frequency after any treatment.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
