What is Phentermine?

Phentermine is an appetite suppressant of a pharmacological group of amphetamines and phenethylamines. This medication was approved to help reduce weight in obese patients for short-term use and combination with exercise, diet and behavior changes. It usually prescribed to individuals who have health risks due to their weight. This active ingredient phentermine (or fentermina in spanish, phenterminum in latin name) is manufactured and distributed in various countries under different trade brand and generic names, for example: Adipex-P (Teva), Ionamin (Celltech), Acxion (Investigacion Farmaceutica), Fastin (GlaxoSmithKline), Duromine (iNova, Douglas Pharmaceuticals), Panbesy (Eurodrug Laboratories), Phentermine (KVK-TECH), Phentermine (Eon Labs), etc. In several countries (such as the USA, Canada, Australia) this drug is a controlled substance because it can cause addiction.

Pharmacological action

Phentermine acts on the brain neurotransmitters. This medication is a central stimulant and an isomer of methamphetamine. It stimulates neurons to release a particular group of neurotransmitters known as catecholamines among which are dopamine, epinephrine (also called adrenaline) and norepinephrine. The appetite suppression activity of these compounds is due to its action on the central nervous system. This mechanism of action is similar to other stimulant appetite suppressants such as diethylpropion and phendimetrazine. The neurotransmitters signal the alert response which also stops the hunger.

Why is Phentermine by Amide Pharmaceutical prescribed?

This medication is used to reduce body weight in obese or overweight patients. Often it prescribed in a regimen of weight reduction based on exercise, behavioral modification, and caloric restriction in the management of exogenous obesity for obese or overweight patients with the presence of other risk factors (e.g., hypertension, diabetes, hyperlipidemia). Phentermine works by directly affecting the area of the brain that controls your appetite making you feel less hungry.

Dosage and administration

It is recommended to use phentermine only in the short term (usually about 12 weeks) and then other non-pharmacological strategies for weight loss and healthy dieting and exercise. However, recommendations limiting its use for short-term treatment are controversial. One reason for the restriction to 12 weeks is drug tolerance, as phentermine loses its appetite-suppressing effects after the body adjusts. On the contrary, it has been shown that this drug did not lose its effect in a trial of 36 weeks. Due to the risk of insomnia, it is recommended taking phentermine before breakfast or 1-2 hours later.
