Phentermine is a sympathomimetic amine, which is similar to an amphetamine. It is also known as an "anorectic" or "anorexigenic" drug. Phentermine
stimulates the central nervous system (nerves and brain), which increases your heart rate and blood pressure and decreases your appetite. Phentermine & Adipex are used as a short-term supplement to diet and exercise in the treatment of obesity. Cialis Levitra and Viagra work by a similar mechanism to cause erection. There are subtle differences in how long the drug works and how quickly it works. Levitra works a little longer than Viagra and takes effect a little faster than Viagra. They both take effect in about 30 minutes. With Levitra the effects last for about 5 hours. The effects with Viagra last 4 hours. According to some experts, Cialis
takes a bit longer to work, but the effects last for much longer two to three days. Officially, the manufacturer claims that Cialis is effective for 36 hours.
