Contemporary therapeutic uses for resorcinol primarily revolve around the use of the phenol derivative as an active ingredient in topical antiseptics or as topical antibacterial skin treatment products for conditions like acne, seborrheic dermatitis, eczema, and others.
In vitro and in vivo studies have demonstrated that resorcinol can inhibit peroxidases in the thyroid and subsequently block the synthesis of thyroid hormones and cause goiter. Resorcinol interferes with the iodination of tyrosine and the oxidation of iodide. In an in vitro study involving lactoperoxidase (LPO) and thyroid peroxidase (TPO), it was shown that the mechanism of these two enzymes can become irreversibly inhibited by way of a suicide inactivation by resorcinol. It is believed that the Fe3+ of the porphyrin residue of the peroxidase to is oxidised to Fe4+ by hydrogen peroxide with the transfer of an oxygen radical. In LPO and TPO, the resulting -cation radical of the porphyrin can isomerize to a radical cation with the radical in an aromatic side chain of the enzyme. The latter radical can bind, in a pH-dependent reaction, covalently and irreversibly to the resorcinol radical formed during regular oxidation of resorcinol and this reduces the activity of the enzyme greatly. While the inactivation of the enzyme and the binding of resorcinol to the enzyme may be largely increased by the presence of 0.1 nM iodide, increasing the iodide concentration to 5 mM reduced the resorcinol binding to the enzyme by one quarter but increased the enzyme activity, determined as the rate of iodination of tyrosine, more than proportionally from 6.2% to 44.7%. Nevertheless, the role played by iodide ions in the irreversible inactivation of the enzymes is not yet fully elucidated. Ultimately, such in vitro and in vivo data propose that the anti-thyroidal activity of resorcinol is caused by inhibition of thyroid peroxidase enzymes, resulting in decreased thyroid hormone production and increased proliferation due to an increase in the secretion of TSH (thyroid stimulating hormone). The iodination process is catalyzed by a haem-containing enzyme, and resorcinol is known to form covalent bonds with haem. Despite the legitimacy of this pharmacodynamic profile in resorcinol, the therapeutic uses for which it may be formally indicated for at this time do not actually rely upon any of these mechanisms or dynamics, which are primarily elicited only upon systemic exposure to resorcinol or particularly high overdosage of the agent. This is especially true, considering resorcinol is most commonly available as topical applications to the public.

Absorption
The dermal absorption of resorcinol seems to be low (< 1%) when applied on healthy and intact skin. The agent absorbed very slightly under normal conditions & the absorption was lower when applied to the scalp than to clean shaven skin due to a strong fixation by the hair.
Route of Elimination
Specific data regarding the route of elimination of resorcinol is not readily available, although the major metabolite of resorcinol found in the urine was its glucuronide.
Volume of Distribution
Specific data regarding the volume of distribution of resorcinol is not readily available, although it is believed that the compound's volume of distribution is considered large, owing to resorcinol's profile as a lipid-soluble compound.
Clearance
Specific data regarding the clearance of resorcinol is not readily available, although it is generally believed that the relatively low topical absorption or resorcinol does not result in an extensive systemic presence and clearance.
A dose of 112 mg/kg of (14)C resorcinol was orally administered to 3 male and 3 female Fischer 344 rats. After one day, the animals were sacrificed, and major tissues and excretory products were analyzed to determine the fate of the resorcinol. Only trace amounts of the compound were found in any tissue and there was no evidence of specific organ accumulation. More than 90% of the total administered dose was recovered from the excreta in 24 hr. The primary route of excretion was in the urine. Only 1 to 2% of the dose was eliminated in the feces and less than 0.1% was eliminated as CO2. Cannulation of the common bile duct followed by iv injection of 11.2 mg/kg resorcinol indicated that excretion in bile was rapid and underwent enterohepatic circulation to be excreted in the urine. Less than 50% of the parent compound was excreted in the urine, most was in the form of four metabolites. The major metabolite of resorcinol was a glucuronide conjugate (approximately 70%). One metabolite was identified as a sulfate conjugate (10-20%), one was identified as a diconjugate with glucuronide and sulfate (5-10%), and one, present in small quantities (less than 2%), was suggested to be a diglucuronide conjugate. Repeated exposure of both sexes to daily doses of 225 mg/kg for 5 days did not alter the rate or relative metabolite ratio of resorcinol excretion.

Resorcinol absorbed very slightly under normal conditions & the absorption was lower when applied to the scalp than to clean shaven skin due to a strong fixation by the hair. The results were somewhat similar in humans, rhesus monkeys & guinea pigs.

Pharmacokinetic data on resorcinol were obtained from studies in the rat. The drug, administered in an aqueous solution, rapidly cleared plasma via urine and did not accumulate in tissues. In the urine, the major metabolite of resorcinol was its glucuronide. Repeated dosing for 30 days with maximum tolerated daily doses of 100 mg/kg did not alter pharmacokinetic parameters, nor did it cause overt toxic signs or adverse reactions. The animals' body weight, blood values, levels of serum T3 and T4, and the gross and microscopic appearance of the thyroid gland and spinal cord remained within normal limits throughout the study.

Specific data regarding the half-life of resorcinol is not readily available, although, in one case of dermal exposure, an adult male with a 90% phenol exposure had an elimination half-life of about 14 hours.
Data regarding the specific mechanisms of action of resorcinol does not appear to be readily accessible in the literature. Nevertheless, the effectiveness of the agent in treating various topical, dermatological conditions by eliciting antibacterial and keratolytic actions appears to stem from resorcinol's propensity for protein precipitation. In particular, it appears that resorcinol indicated for treating acne, dermatitis, or eczema in various skin care topical applications and peels revolves around the compound's ability to precipitate cutaneous proteins from the treated skin.
In animal studies resorcinol failed to induce thyroid gland (TG) toxicity, unless pharmacokinetic/toxicokinetic (PK/TK) conditions were manipulated (e.g., injection of resorcinol in oil or application in a slow release formulation). A recently completed two-generation reproductive toxicity study in rats did not detect any adverse effects on either reproductive or TG end points. Resorcinol intake via drinking water up to the palatability limit had resulted in average daily intakes (mg/kg) of 233 in F0 and F1 males and 304 (premating/gestation) or 660 (lactation) in females. Free resorcinol in blood plasma was barely detectable in a few parental animals, indicating rapid metabolism. This short review communication offers a perspective on compromised human skin barrier function as a likely cause of drastic increases in resorcinol absorption. In conjunction with multiple daily applications over many months to hyperemic, inflamed, and lesioned human skin much higher absorption was likely responsible for the reported human TG toxicity.
