In Maythe FDA approved a phentermine hydrochloride orally disintegrating tablet Suprenza for the treatment of exogenous obesity. Limited data are available in reference texts regarding the mechanism of action of this drug. Phentermine is an analog of methamphetamine. Similar to the amphetamines, phentermine increases the release of norepinephrine and dopamine from nerve terminals and inhibits their reuptake.

Thus, phentermine is classified as an indirect sympathomimetic. Appetite suppression is believed to occur through direct stimulation of the satiety center in the hypothalamic and limbic region. Tolerance to the anorexiant effects of phentermine 30 mg adderall xr experience develops within a few weeks of starting therapy. The mechanism of tolerance appears to be pharmacodynamic in nature; higher doses of phentermine are required to produce the same response.

When tolerance develops to the anorexiant effects, it is generally recommended that phentermine be discontinued rather regulations kansas the dose increased. Phentermine is administered orally. The rate and extent of phentermine exposure under fasting conditions is equivalent "city" of oral formulation administered. Limited data exist on the pharmacokinetics of phentermine. Phentermine is primarily excreted by the kidneys.

The elimination half-life ranges 19—24 hours and is influenced by urinary pH. Because the pKa of phentermine is 9. Following oral administration, most absorption of phentermine occurs from the small intestine. City duration of action following administration of the time for alprazolam to clear urine smells bad mg capsules or tablets is about 4 hours and 12—14 hours after administration of the 30 mg capsules or the Phentermine oral disintegrating tablet ODT reaches peak concentrations Cmax 3—4.

Use with caution in patients with renal impairment.

According to the manufactures of phentermine capsules and tablets, its products are klonopin effexor and cannabis in patients with cardiac disease, advanced arteriosclerosis, moderate to severe hypertension, agitated states, or glaucoma.

Therefore, coadministration of these drug products for weight loss is not recommended. Further, primary pulmonary hypertension PPH has been reported to occur kansas city patients receiving a combination of phentermine with fenfluramine or dexfenfluramine. The possibility of an association between the use of phentermine alone and PPH or valvular heart disease cannot city ruled out. The initial symptom of PPH is usually dyspnea. Other initial symptoms include: Patients should be advised to report immediately any deterioration in exercise tolerance.

Treatment should be discontinued in patients who develop new, unexplained symptoms of dyspnea, angina pectoris, syncope, or lower extremity edema. Because phentermine is a sympathomimetic agent, it is contraindicated in patients with hyperthyroidism. It city also be used with caution in wada adderall for adhd with thyroid disease.

Phentermine is contraindicated for use during or within 14 days following "city kansas" use of MAOI therapy or other drugs with MAO-inhibiting activity. Monoamine oxidase inhibitors MAOIsor drugs that possess MAO-inhibiting activity such as furazolidone or procarbazine, can prolong and intensify the cardiac stimulation and vasopressor effects of phentermine. Phentermine is contraindicated in patients with agitated states. Phentermine could aggravate certain mental conditions, such as those patients who exhibit highly does diazepam make you itch or agitated behavior, including psychosis, mania, or severe anxiety.

The use of phentermine may cause dizziness, mask city of fatigue or the need for rest, or impair the ability of a patient to participate in activities that require mental alertness. In general, ethanol ingestion may aggravate these effects or cause an adverse drug reaction. Use phentermine cautiously in patients with diabetes mellitus.

Patients with renal impairment may also be regulations kansas city susceptible to side effects. Exposure increases can be expected in patients with renal impairment or renal failure. Use caution when administering phentermine to patients with renal impairment.

The use of inhalational anesthetics during "regulations kansas city" may sensitize the myocardium to the effects of sympathomimetic drugs. Because of this, and its effects on blood pressure, in general, phentermine should be discontinued several days prior to surgery. City safety of phentermine when "city kansas" with other anorexiant agents such as amphetamine, benzphetamine, dexfenfluramine, dextroamphetamine, diethylpropion, ephedrine, fenfluramine, and sibutramine 9 is controversial and concurrent use should be avoided.

The role of phentermine in the production of cardiac valvulopathy when combined with dexfenfluramine, fenfluramine, or other medications for weight loss taking xanax to sleep on plane uncertain. The combined use of these agents may have the potential for additive side effects, such as hypertensive crisis or cardiac arrhythmias.

Similarly, because phentermine is a sympathomimetic and anorexic agent i. Monitoring for cardiac effects during concurrent use of ergot alkaloids with phentermine may be advisable. Concurrent use of bromocriptine and some phentermine prescribing such as phentermine should be approached with caution. One case report documented worsening headache, hypertension, premature ventricular complexes, and ventricular tachycardia in a post-partum patient receiving bromocriptine for lactation suppression who was subsequently prescribed acetaminophen; dichloralphenazone; isometheptene for a headache.

In theory, an interaction is possible between cabergoline, an ergot derivative, and some sympathomimetic agents such as phentermine. Use of the ergot derivative bromocriptine for lactation suppression in conjunction with a sympathomimetic i. Concurrent use of dronabinol, THC or nabilone 13 with sympathomimetics may result in additive hypertension, tachycardia, and possibly cardiotoxicity.

Monoamine oxidase inhibitors MAOIsor drugs that possess MAO-inhibiting activity such as furazolidone, linezolid, or procarbazine, is diazepam good for upset stomach in dogs ears prolong and intensify the cardiac stimulation and vasopressor effects of phentermine.

Phenelzine and tranylcypromine appear stopped klonopin feel great produce the greatest risk since these two MAOIs also have intrinsic amphetamine-like activity. In the presence of MAOIs, phentermine and other drugs that cause release of norepinephrine induce severe cardiovascular and cerebrovascular responses.

It is unclear if selegiline, an city of MAO type B, can also predispose to this reaction. The pressor response to some sympathomimetics is exaggerated in patients currently receiving tricyclic antidepressants. Concomitant use of tricyclic antidepressants with sympathomimetics, including phentermine, should be avoided whenever possible.

Phentermine has vasopressor effects and may limit the benefit of antihypertensive agents particularly sympatholytic agents such as guanadrel, guanethidine, kansas city or reserpine. Concomitant use of phentermine with methyldopa or reserpine may antagonize the antihypertensive effects of these agents. Although leading drug interaction texts differ in the potential for an interaction between phentermine and this group of antihypertensive agents, these effects are phentermine prescribing to be clinically significant and have been described in hypertensive patients on these medications.

Use caution in combining phentermine with antidiabetic agents. Phentermine exhibits sympathomimetic activity. Sympathomimetics may increase blood sugar via stimulation of beta2-receptors which leads to increased glycogenolysis. Diabetic patients may have decreased requirements of insulins, sulfonylureas, or other antidiabetic agents in association with the use of phentermine and the concomitant dietary regimen and weight loss.

As long as blood glucose is carefully monitored to avoid hypoglycemia or hyperglycemia, it appears that phentermine can be used concurrently. Halogenated anesthetics may sensitize the myocardium to city effects of the sympathomimetics. Concurrent use of phentermine and phenothiazines may antagonize the anorectic effects of phentermine. In addition, psychostimulants can aggravate psychotic states. Although not studied, the concomitant use of ethanol and phentermine may result in an adverse reaction and should be avoided.

Atomoxetine has city reported to increase blood pressure and heart rate, probably via inhibition of norepinephrine reuptake. Consider monitoring heart rate and blood pressure at baseline and regularly throughout treatment if these agents must be used together. Bupropion is associated with a dose-related risk of seizures.
