Hexestrol diacetate (brand name Retalon-Lingual among others) is an ester of hexestrol. It is a synthetic estrogen that was used for the treatment of menstruation disorder. It is an estrogen receptor agonist. A single therapeutic dose of hexestrol diacetate administered in impuber sheep has been shown to induce massive follicular atresia. So the incorrect utilisation of some hormonal formulations and the consumption of forages that contain estrogen like compounds, can represent major causes of infertility in sheep.

Bisdequalinium (also known as R-199, trade name Solvidont) is an antibacterial agent for endodontic use. Bisdequalinium was available in three dispensing forms: an irrigation solution, a working solution, and a medication paste. They contained 0.125 %, 0.5 %, and 0.48 % Bisdequalinium respectively. The low cytotoxicity and high antimicrobial effects, detergent, and lubricating and chelating properties, all claimed in the manufacturer's brochure, make this material an appropriate candidate for clinical endodontic use.
