How Alka-Seltzer works in the body?
As described above, there are many Alka-Seltzer products with different formulation and combination of active ingredients. Active ingredients that can be found in Alka-Seltzer products are following: aspirin, chlorpheniramine, phenylephrine, acetaminophen, citric acid, sodium-bicarbonate, dextromethorphan, diphenhydramine and doxylamine.
Aspirin works as an irreversible inhibitor of both prostaglandin synthesis and platelet aggregation and it is stronger than other salicylic acid derivatives. This makes acetylsalicylic acid different from other NSAIDS (such as diclofenac and ibuprofen) which are reversible inhibitors. As a result of prostaglandin synthesis inhibition analgesic, antipyretic, and anti-inflammatory effects are caused.
Chlorpheniramine works by blocking the muscle responses to histamine and acts as an antagonism of the constrictor effects of histamine on respiratory smooth muscle. It acts as histamine H1 antagonist and is used for relieving allergic reactions such as: rhinitis, hay fever, urticaria, and asthma.
Phenylephrine is a vasoconstrictor substance with decongestant properties that relieves symptoms resulting from upper respiratory tract irritation. It shrinks inflamed mucous membranes, decreases nasal congestion and tissue hyperemia. Phenylephrine is a sympathomimetic amine that works predominantly as agonist of α1 -adrenergic receptors. It also has some effects on beta adrenergic receptors.
Acetaminophen works by inhibiting pain impulse generation peripherally and may inhibit the production of prostaglandin in the CNS. It also reduces fever by inhibiting hypothalamic heat-regulating center.
Doxylamine is antihistamine drug that competitively blocks histamine from binding to H1 receptors. It has significant antimuscarinic activity and penetrates CNS, which may induce sedation.
Citric acid and sodium bicarbonate are antacids which neutralizes stomach acid
Dextromethorphan works as a cough suppressant with central effects on cough center in medulla.

Can patients with liver disease use Alka-Seltzer safely?
Some Alka-Seltzer products contain acetaminophen which is primarily metabolized in the liver to inactive forms. However, small amounts of the medicine are converted by minor pathways to metabolites that can cause hepatotoxicity or methemoglobinemia. Patients with hepatic impairment may be at increased risk of toxicity due to increased minor metabolic pathway activity. Severe liver injury, including cases of acute liver failure resulting in liver transplant and death, has been reported in patients using acetaminophen. Therapy with acetaminophen should be administered cautiously in patients with hepatic insufficiency.
