PROMETHAZINE HCL

Promethazine HCl is a phenothiazine antihistamine that blocks H1 receptors and has strong sedative and antiemetic properties. It is used for allergy symptoms, motion sickness, nausea, and preoperative sedation. Side effects include drowsiness, dry mouth, blurred vision, constipation, hypotension, and rare neuroleptic reactions or respiratory depression, especially in children. Only GMP materials will be supplied, logistics all according to GDP.

Product Description


Mechanism of Action

PROMETHAZINE HCL demonstrates a highcomplexity biochemical interaction profile characterised by multilayer signalling integration, modular enzymatic pathway penetration, mitochondrial network modulation, ionflux recalibration, redoxstate equilibrium restructuring and transcriptionfactor axis reprogramming. Its molecular geometry enables conformational docking to catalytic pockets, allosteric domains, transmembrane receptor helices and cytoskeletal scaffolds, creating broad regulatory influence across metabolic, structural and genomic systems.

At the signalling level, PROMETHAZINE HCL may modulate phosphorylation gradients, kinome cascade propagation (including MAPK, JNK, ERK, PI3KAKT, and AMPK axes), Gprotein subunit turnover, calcium wave propagation, secondary messenger amplification and stressadaptation thresholds. Mitochondrially, the compound can alter electrontransportchain efficiency, ATPADP cycling, mitochondrial ROS leakage, membrane potential polarity and respiratorycomplex activation ratios.

Advanced Research Value

PROMETHAZINE HCL is particularly suited for:

  • Crosspathway interference mapping and kinome interaction grids
  • Ultrahigh resolution receptorligand docking and conformational prediction
  • Organellestress modelling (ER stress, mitochondrial folding stress, autophagic flux modulation)
  • Networklevel transcriptome rewiring using multiomics clustering
  • Precision cytoskeletalmechanics analysis including actin polymerisation and tubulin turnover
  • Apoptotic vs. survivalpathway bias quantification
  • Advanced SAR, QSAR and machinelearning molecularperformance modelling

Risks, Toxicodynamics & Cellular Hazard Spectrum

At elevated exposure levels, PROMETHAZINE HCL may induce:

  • ROS surge and oxidative collapse
  • Mitochondrial hyperfragmentation or respiratorycomplex shutdown
  • Severe ionchannel destabilisation
  • Cytoskeletal disassembly and membrane-integrity breach
  • Aberrant transcriptionfactor activation, inflammatory bursts (NF-κB, STAT, IRF pathways)
  • Highgrade apoptosis, necroptosis or ferroptosis initiation
  • Epigenetic instability affecting methylation/acetylation balance

Storage Condition

Promethazine hydrochloride preparations should be protected from light. Promethazine hydrochloride oral solution and tablets should be stored in tight, light-resistant containers at 15-30 and 20-25 °C, respectively, while the rectal suppositories should be stored in well-closed containers at 2-8 °C. Freezing of the oral solution should be avoided. Following the date of manufacture, commercially available promethazine preparations have expiration dates of 2-5 years depending on the dosage form and manufacturer.
