DB06711 - Naphazoline


Identification
Name Naphazoline
Accession Number DB06711
Type small molecule
Description Naphazoline is a rapid acting sympathomimetic vasoconstrictor of occular artierioles. It acts to decrease congestion of the conjunctiva and is found in many over-the-counter eye drops.

Pharmacology
Indication Naphazoline is primarily indicated in conditions like Corneal vascularity, Hyperaemia, Itching, Nasal congestion, and can also be given in adjunctive therapy as an alternative drug of choice in Sinusitis
Mechanism of action Naphazoline is a direct acting sympathomimetic drug, which acts on alpha-adrenergic receptors in the arterioles of the nasal mucosa. This activates the adrenal system to yield systemic vasoconstrction. In producing vasoconstriction, the result is a decrease in blood flow in the nasal passages and consequently decreased nasal congestion. The vasoconstriction means that there is less pressure in the capillaries and less water can filter out, thus less discharge is made.

Toxicity Extended usage of Naphazoline can result in decreased effectiveness or a build up of tolerance against the drug. The number of receptors decreases, and when the administration of the drug is ceased, chronic congestion can occur; this is called rhinitis medicamentosa, commonly referred to as rebound congestion. Moreover long-term overdosing can cause degenerative changes in nasal mucous membranes that pose another health problem.
