Buy Blood Purification Activated Carbon
Activated charcoal is mainly used in blood purification using hemoperfusion. Hemoperfusion is the method where blood is taken extracorporeally (outside body) from the patient, and introduced to a cartridge or column of tiny granules of activated charcoal. The structure of activated charcoal consists of multiple pores, and amounts to a large surface area, which allows activated charcoal to adsorb a variety of toxins and metabolic waste products directly from the blood through physical adsorption and hydrophobic interactions. Activated charcoal is effective at removing small to medium-sized, unbound, and hydrophobic molecules as well as some protein-bound substances. Examples of agents that can be removed with activated charcoal are certain drugs (for example, barbiturates, theophylline), as well as toxins (for example, paraquat, Amanita phallotoxin) and uremic toxins (i.e. toxins related to liver failure or extreme poisoning.)

Biocompatibility Concerns
- The presence of uncoated charcoal particles stimulates platelets and leukocytes, which can increase the chances of thrombosis, thus once a length of time goes by microparticles can be released during perfusion which can lead to microemboli creation but also necessitates complex polymer coatings (like cellulose acetate) which can also slow the rate of adsorption.
Limited Solute Removal Capacity
- Activated charcoal can remove small-to-medium size (<~10 kDa) hydrophobic toxins (toxins such as neurotoxic drugs and poisons), but charcoal is completely ineffectual against electrolytes, urea, or larger (~20+ kDa) protein bound uremic toxins, while also requiring hybrid systems - necessitating hemodialysis/hemofiltration - ultimately complicating the treatment protocol.
Selective Capability (adsorption)
- Non-specific adsorption studies will also remove relevant medications (likely antibiotics and anticoagulants) and nutrients alongside the target toxins, making it unmanageable to monitor therapy.
- Additionally, plasma proteins will also non-specifically absorb and compete for binding capacity for the target toxins, further recommending reducing binding capacity.
Material Standardization Issues
- Performance reproducibility is complicated by differences in pore structure and surface area for each source of charcoal.
- Biocompatible coatings on the charcoal can also have differences in durability, leading to leaking charcoal particles, or impaired adsorption capacity during sustained application.
Clinical Protocol Constraints
- Therapeutic protocols are limited due to decreased adsorption capacity and adverse effects to biocompatibility - they are not restricted to a single application.
- Any re-bound toxin release that may come from the charcoal during application may require multi-sessions.
