Hi..we first select drug by its chemical components..we also check chemical’s solubility, pH etc…now we can’t give this drug direct to humans as we don’t know how toxic it is??so we need to run toxicology studies on small lab animals(like rats, mice, guinea pig, hamster etcc..) to check safety of drug…If it passes the safety the drug will test on little bit bigger animals (similar to humans in physiology like dogs, monkeys, pigs etc..)..Once the drug pass the testing in animals we check the safety and efficacy in small number of people first (may be one or two)..and the dose will be so much lower than animals. we required to have good safety margin between dose in animal and human….further we check effects on larger group on humans..and thus when it will be safe and ready it will go for registration in regulatory body like FDA (food and drug administration)…out of thousands of drugs one or two will go to market as medicine….this process will take 10-15 years in total…I hope i tried to answer your question in summary…but believe me it is one of the expensive business..comapnies spend lots of money on research for medicines…because human’s health is involved in this and we need to give better medicines to patients to do more, feel better and live longer…
