Sinclair has experience with all conventional routes of compound administration, including transdermal and dermal applications. Sinclair has developed a white, hairless Yucatan miniature swine for dermal absorption, irritation, and photosensitivity studies. The Hanford miniature swine, having white skin, has also been extensively used for dermal studies. The Sinclair miniature swine is a very good candidate for subacute to chronic toxicology because of its slow growth rate, docile temperament, and various hair coat colors facilitating identification.
