Capromorelin is a potent ghrelin receptor agonist. Capromorelin is indicated for appetite stimulation in dogs. Plasma insulin-like growth factor-I (IGF-I) was elevated progressively over a 5-d course of daily oral dosing in dogs. In healthy older adults at risk for functional decline, administration of the capromorelin may improve body composition and physical function. Adverse events included fatigue, insomnia, and small increases in fasting glucose, glycosylated hemoglobin, and indices of insulin resistance.

L-methylephedrine is an isomer of DL form, which possesses beta 1-adrenoceptor agonist activity, while d-isomer is suggested to have only low or no affinity for beta 1-adrenoceptors.

Clenbuterol is agonist of beta2 adrenergic receptor. In some countries it is used as bronchodilator for treatment of asthma, but is not approved in USA. The drug is abused by bodybuilders and athletes for its ability to increase lean muscle mass and to reduce body fat. In 1998 FDA approved the clenbuterol-based Ventipulmin Syrup as a prescription-only drug for treatment of airway obstruction in horses.

Stearalkonium chloride, a safe surfactant with antimicrobial properties, which is used in cosmetic products at concentrations of ≤0.1 to 5%.

Sodium isobutoxide is an alkoxide of isobutanol. It is used in organic chemistry for the synthesis of isobutyl ethers.

Ractopamine is a feed additive to promote leanness in animals raised for their meat. Pharmacologically, it is a TAAR1 agonist and β adrenoreceptor agonist that stimulates β1 and β2 adrenergic receptors. Ractopamine is known to increase the rate of weight gain, improve feed efficiency, and increase carcass leanness in finishing swine. Its use in finishing swine yields about three kilograms of additional lean pork and improves feed efficiency by 10%. Ractopamine is the active ingredient in products known as Paylean for swine and Optaflexx for cattle, developed by Elanco Animal Health, a division of Eli Lilly and Company, for use in food animals for growth promotion. Ractopamine use has been banned in most countries, including the European Union, mainland China and Russia while 27 other countries, such as Japan, the United States, Canada, and South Korea, have deemed meat from livestock fed ractopamine safe for human consumption. Ractopamine is safe for finishing pigs heavier than 240 lb (110 kg) when administered in the diet at concentrations up to 10 ppm and fed for up to 35 days.
