How does Phentermine work in the body?
Phentermine works by stimulating the central nervous system, which increases heart rate and blood pressure, and decreases appetite. It is thought to work by increasing the levels of neurotransmitters in the brain, such as norepinephrine, which helps to reduce hunger and control appetite. This mechanism of action is similar to that of amphetamines, although phentermine is less potent and is considered safer for short-term use.
In what forms is Phentermine available?
Phentermine is available in several dosage forms to accommodate different patient needs. It is commonly prescribed in tablet form, with dosages typically ranging from 8 mg to 37.5 mg. Capsules are also available, providing an alternative for those who may have difficulty swallowing tablets. Some formulations are designed for extended release, allowing for once-daily dosing. It is important to follow your healthcare provider's instructions regarding the specific form and dosage that is right for you.
