PABA derivatives reportedly have weak sensitization potential, but the incidence of allergic and photoallergic contact dermatitis associated with their use is increasing. Contamination of PABA derivatives with benzocaine which may cause allergic reactions has been reported. In patients allergic to compounds that are structurally similar to PABA (e.g., ester-type anesthetics, aniline dyes, thiazides, sulfonylurea and paraphenylenediamine drugs), cross-sensitivity to PABA derivatives has been reported occasionally; therefore, sunscreens containing PABA derivatives may be contraindicated in patients with a history of hypersensitivity to these chemicals.

Because the absorptive characteristics of skin of children younger than 6 months of age may differ from those of adults and because the immaturity of metabolic and excretory pathways of these children may limit their ability to eliminate any percutaneously absorbed sunscreen agent, sunscreen products should be used in children younger than 6 months of age only as directed by a clinician. It is possible that the characteristics of geriatric skin also differ from those of skin in younger adults, but these characteristics and the need for special considerations regarding use of sunscreen preparations in this age group are poorly understood. /Sunscreens/

Little information is available regarding the safety of chronic sunscreen usage, but commercially available physical and chemical sunscreens appear to have a low incidence of adverse effects. Derivatives of PABA, benzophenone, cinnamic acid, and salicylate and 2-phenylbenzimidazole-5-sulfonic acid have caused skin irritation including burning, stinging, pruritus, and erythema on rare occasions. /Sunscreens/

For more Drug Warnings (Complete) data for PADIMATE O (12 total), please visit the HSDB record page.
Indicated as an active UV-B filter to prevent photodamage.
Padimate O absorbs UV-B rays, which can in turn induce DNA damage in human keratinocytes. While treatment of padimate O suppresses the formation of UV-endonuclease-sensitive sites, there is also an increase in direct strand breaks of DNA in cells.
Sunscreening Agents
Chemical or physical agents that protect the skin from sunburn and erythema by absorbing or blocking ultraviolet radiation. (See all compounds classified as Sunscreening Agents.)
Absorption
Padimate O is capable of human skin penetration.
Route of Elimination
No pharmacokinetic data available.
Volume of Distribution

... None of the subjects tested showed any sign of skin irritation at the application site. ... In four postmenopausal women (age 54-63 years, weight 67-93 kg) the mean estradiol level 24 hr postapplication over the 9 day study period was 53 pg/mL. This result was significantly greater (p < 0.001) than the baseline value of 13 pg/mL. The mean estradiol/estrone ratio also rose significantly (p < 0.04) from a baseline value of 0.2 up to 0.8.

It appears that sunscreen agents are absorbed by the intact epidermis to varying degrees. /Sunscreens/

Sunscreen skin penetration and safety assessment should be considered together in order to ensure that in vitro cytotoxicity studies examine relevant doses of these organic chemical UV filters to which viable epidermal cells are realistically exposed. In this study, /investigators/ sought to determine whether sufficient topically applied sunscreens penetrated into human viable epidermis to put the local keratinocyte cell populations at risk of toxicity. The penetration and retention of five commonly used sunscreen agents (avobenzone, octinoxate, octocrylene, oxybenzone and padimate O) in human skin was evaluated after application in mineral oil to isolated human epidermal membranes. Sunscreen concentration-human keratinocyte culture response curves were then defined using changes in cell morphology and proliferation (DNA synthesis using radiolabelled thymidine uptake studies) as evidence of sunscreens causing toxicity. Following 24 hr of human epidermal exposure to sunscreens, detectable amounts of all sunscreens were present in the stratum corneum and viable epidermis, with epidermal penetration most evident with oxybenzone. The concentrations of each sunscreen found in human viable epidermis after topical application, adjusting for skin partitioning and binding effects, were at least 5-fold lower, based on levels detected in viable epidermal cells, than those appearing to cause toxicity in cultured human keratinocytes. It is concluded that the human viable epidermal levels of sunscreens are too low to cause any significant toxicity to the underlying human keratinocytes.

Researchers in Europe analyzed samples of human milk for the presence of sunscreens and other chemicals with possible endocrine activity. Mothers were asked about their use of sunscreens and cosmetics that contained sunscreen ingredients (benzophenone 2, benzophenone 3, 3-benzylidene camphor, 4-MBC, OMC, homosalate, octocrylene, and octyl-dimethyl PABA). Responding to questionnaires, 78.8% of the women reported using products that contained sunscreens; 76.5% of human milk samples contained these chemicals. There was a high correlation reported between mothers' use of these chemicals and their concentrations in human milk. The authors concluded that except for lipsticks (the ingestion of which is probably important), their results agree with studies in animals and humans showing dermal absorption of sunscreens. Given that some of these chemicals have endocrine activity in animals, the authors suggested that exposure could be lessened if mothers abstained from using these products during their children's sensitive life stages.

Information on the cutaneous absorption, distribution, and elimination of most topically applied sunscreen agents is limited. Solvents used in sunscreen products affect the stability and binding of the drug to the skin; in general, alcoholic solvents allow for the most rapid and deepest epidermal penetration of sunscreens. It appears that sunscreen agents are absorbed by the intact epidermis to varying degrees. PABA reportedly diffuses into the stratum corneum, reaching maximum concentrations there 2 hours following application, but apparently does not penetrate deeper layers of the skin to a substantial extent. Homosalate's penetration also appears to be limited to the stratum corneum. One study in animals indicated that PABA may penetrate the skin to a greater extent than does padimate A. Although some studies have shown that substantive concentrations of PABA remain on the skin after washing, other studies have failed to confirm this. One study showed that PABA esters were removed from the skin less readily than was PABA or other chemical sunscreens. /PABA/

It is proposed that simultaneous contact of padimate O with keratinocytes can stimulate the diffusion through human epidermis. Upon photoexcitation, padimate O generates singlet oxygen and forms carbon-centred free radicals. While padimate O attenuates simple and repairable, UV-induced cellular damage, it may also increase complex chemical damage that is more difficult to repair by normal cells.
Radiation is absorbed by chemical sunscreens when the electron energy level of the drug is raised from its ground state to a higher energy level or excited state. Chromophore groups (C=C, C=O, O-N=O) with loosely held electrons are easily excited by radiation. Compounds which have several chromophore groups in optimal positions have high absorbance over a broad range of wavelengths. Chemical sunscreens are usually agents that absorb not less than 85% of UVB radiation (thus preventing burning) but may permit transmission of UVA radiation (thus allowing tanning). Some sunscreens may absorb wavelengths over a range that is slightly wider or narrower than that of UVB. All PABA derivatives absorb wavelengths of approximately 290-320 nm, benzophenone derivatives absorb wavelengths of approximately 250-360 nm, cinnamic acid derivatives absorb wavelengths of 280-320 nm, and salicylate derivatives and other miscellaneous chemical sunscreens absorb wavelengths of about 270-320 nm.
American Society of Health-System Pharmacists 2013; Drug Information 2013. Bethesda, MD. 2013
The wavelength to which the skin is maximally sensitive had been accepted for many years to be 296.7 nm; however, recent evidence suggests that the most erythemogenic UVB wavelength may be slightly lower (e.g., somewhere in the range of 292-295 nm). In addition, of the stronger burning wavelengths that reach the earth's surface, most are approximately 310 nm. Therefore, sunscreens that maximally absorb UVB radiation near either of these wavelengths are particularly effective at preventing sunburn. Maximum absorbance occurs at about 290 nm for PABA, at about 295 nm for glyceryl-p-aminobenzoate, and at about 310 nm for the remaining PABA derivatives. Maximum absorbance occurs at 280-290 nm for benzophenone derivatives, at 310 nm for cinnamic acid derivatives with the exception of diethanolamine-p-methoxycinnamate which has its maximum absorbance at 290 nm, and at 300-305 nm for salicylate derivatives and other miscellaneous sunscreens. /Sunscreens/

... The photomutagenic sunscreen Padimate-O attacks DNA on illumination with simulated sunlight, producing strand breaks and lesions that are labile to N,N'-dimethylethylenediamine but few, if any, cyclobutane dimers or other direct photoproducts. The damage can be completely suppressed by the free radical quenchers Tris, ethanol, mannitol and dimethylsulfoxide, which is commonly used as a solvent in conventional photomutagenicity assays.
