WASHINGTON (Reuters) – Researchers looking for the next generation of erectile dysfunction drugs said on Wednesday they found a precise mechanism that stimulates erections in rats without dangerous side effects.
Their target is a single molecular doorway into nerve cells called a receptor — in this case one used by the message-carrying chemical or neurotransmitter dopamine.
Drugs that stimulate such a specific mechanism could be expected to have their intended effect — an erection — without the dangerous side effects that make Viagra too risky for some heart patients.
