Sutif
Sutif Uses, Dosage, Side Effects, Food Interaction and all others data.
Sutif is an α1-adrenoceptor antagonist which blocks peripheral postsynaptic receptors resulting to decreased arterial tone. It relaxes smooth muscle of the bladder neck causing a reduction of bladder outlet obstruction.
In general, α1-adrenergic receptors mediate contraction and hypertrophic growth of smooth muscle cells. α1-Receptors are 7-transmembrane domain receptors coupled to G proteins, Gq/11. Three α1-receptor subtypes, which share approximately 75% homology in their transmembrane domains, have been identified: α1A (chromosome 8), α1B (chromosome 5), and α1D (chromosome 20). Sutif is the first α1-receptor antagonist to demonstrate selectivity for the α1A-receptor. All three receptor subtypes appear to be involved in maintaining vascular tone. The α1A-receptor maintains basal vascular tone while the α1B-receptor mediates the vasocontrictory effects of exogenous α1-agonists. Activation of α1-receptors activates Gq-proteins, which results in intracellular stimulation of phospholipases C, A2, and D. This results in mobilization of Ca2+ from intracellular stores, activation of mitogen-activated kinase and PI3 kinase pathways and subsequent vasoconstriction. Terozosin produces its pharmacological effects by inhibiting α1A-receptor activation. Inhibition of these receptors in the vasculature and prostate results in muscle relaxation, decreased blood pressure and improved urinary outflow in symptomatic benign prostatic hyperplasia.
Sutif is a quinazoline derivative alpha-1-selective adrenergic blocker.

Uses
Sutif Hydrochloride single therapy is used to relieve for signs and symptoms of benign prostatic hyperplasia (BPH), for the treatment of hypertension
Sutif is also used to associated treatment for these conditions: Benign Prostatic Hyperplasia (BPH), High Blood Pressure (Hypertension), Ureteral Calculus
How Sutif works
Sutif is selective for alpha-1-adrenoceptors but not their individual subtypes. Inhibition of these alpha-1-adrenoceptors results in relaxation of smooth muscle in blood vessels and the prostate, lowering blood pressure and improving urinary flow. Smooth muscle cells accounts for roughly 40% of the volume of the prostate and so their relaxation reduces pressure on the urethra.
It has also been shown that catecholamines induce factors responsible for mitogenesis and alpha-1-adrenergic receptor blockers inhibit this effect.
A final long term mechanism of terazosin and other alpha-1-adrenergic receptor blockers is the induction of apoptosis of prostate cells. Treatment with terazosin enhances the expression of transforming growth factor beta-1 (TGF-beta1), which upregulates p27kip1, and the caspase cascade.
Dosage
Sutif dosage
Benign Prostatic Hyperplasia:
- Initial dose: 1 mg at bedtime is starting dose of all patients and this dose should not be exceeded.
- Subsequent dose: The dose slowly increases to achieve the desired response. The usual recommended dose range is 5-10 mg administered once a day.
Hypertension:
- Initial dose: 1 mg at bedtime is starting dose of all patients and this dose should not be exceeded.
- Subsequent dose: The dose slowly increases to achieve the desired response. The usual recommended dose range is 2-10 mg administered once a day.
Side Effects
Postural hypertension is more commonly reported side effect. Dizziness, lack of energy, peripheral oedema; urinary frequency and priapism reported.
Toxicity
In the event of an overdose, patients may experience hypotension. Blood pressure and heart rate should be controlled by having the patient lie down or by treating with volume expanders or if necessary vasopressors. Patients should be monitored for renal function. Because terazosin is highly protein bound, dialysis is unlikely to provide benefit to overdosing patients.
The oral LD50 in mice is 5500mg/kg.
Precaution
First dose may cause hypotension (within 30-90 minutes). Therefore should be taken on retiring to bed. Caution should be observed when Sutif is administered with other antihypertensive agents; avoid the possibility of significant hypotension. When adding Sutif to a diuretic or other antihypertensive agent, dosage reduction and retitration may be necessary. The patients should be cautioned to avoid situation such as driving and hazardous tasks where injury could result due to syncope after initiation of Sutif therapy.
Interaction
In patients receiving Sutif plus ACE inhibitors or diuretics the proportion reporting dizziness or related side effects was greater than in the total population of Sutif treated patients from clinical trials. Sutif has been given without interaction with analgesics/ anti-inflammatory, cardiac glycosides, hypoglycemic, antiarrhythmic, anxiolytics/ sedatives, antibacterial, hormones/ steroids and drugs used for gout.
Food Interaction
- Take with or without food. A meal does not significantly affect the extent of absorption but delays Tmax by 40 minutes.
Sutif Alcohol interaction
[Moderate] GENERALLY AVOID:
The concurrent use of ethanol and alpha-1 adrenergic blockers may cause increased hypotensive effects.
Patients with aldehyde dehydrogenase deficiencies (primarily Asians) may be at a higher risk of this interaction.
The mechanism has not been determined.
Data exist for prazosin and other alpha adrenergic blockers are expected to interact also.
In addition, any patients taking alpha adrenergic blockers may experience excessive orthostatic hypotension with ethanol ingestion, due to ethanol's unopposed vasodilatory effects in the presence of alpha adrenergic blockade.
Patients who develop
a flushing reaction after ethanol ingestion (indicates a possible aldehyde dehydrogenase deficiency) should be advised to avoid ethanol or limit their intake.
All patients should be warned about the possibility of orthostatic hypotension with concurrent ethanol use.

Sutif Disease Interaction
Volume of Distribution
25L to 30L.
Elimination Route
Approximately 90%.
Half Life
Sutif has a mean half life 12 hours though this can be as high as 14 hours in patients over 70 years and as low as 11.4 hours in patients 20 to 39 years old.
Clearance
Plasma clearance is 80mL/min and renal clearance is 10mL/min.
Elimination Route
Approximately 10% of the oral dose is excreted unchanged in the urine and approximately 20% is excreted in the feces. 40% of the total dose is eliminated in urine and 60% of the total dose is eliminated in the feces.
Pregnancy & Breastfeeding use
The safety of Sutif during pregnancy has not been established so Sutif is not recommended during pregnancy unless the potential benefit justifies the potential risk to moher and fetus. It is not known whether Sutif is excreted in breast milk. Because many drugs are excreted in breast milk, caution should be exercised when Terazosn is administered to a nursing mother.
Contraindication
Sutif is contraindicated in patients known to be hypersensitive to Sutif or its analogues.
Acute Overdose
Acute overdose may lead to acute hypotension, cardiovascular support is of first importance. Restoration of blood pressure and normalization of heart rate may be accomplished by keeping the patient in a supine position. At the same time expansion of plasma volume and nor-adrenergic vasopressor may also be needed.
Storage Condition
Store between 20-25° C. Protect from light and moisture.
