Description

Terazosin hydrochloride is a selective alpha-1 adrenoreceptor competitive blocking agent with a longer duration of action. Terazosin is a quinazoline derivative. It is very rapidly absorbed and performed activity within 15 minutes after oral ingestion.

Pharmacology

Terazosin 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

Do not take any medication without a doctor's prescription. Self-medication can be dangerous.

Benign Prostatic Hyperplasia-

Side Effects

Postural hypotension is more commonly reported side effect. Dizziness, lack of energy, peripheral oedema; urinary frequency and priapism reported.

Pregnancy & Lactation

It is not known whether Terazosin is excreted in breast milk. As many drugs are excreted in breast milk, caution should be exercised when Terazosin is administered to a nursing mother.

Precautions & Warnings

First dose may cause hypotension (within 30-90 minutes). Therefore should be taken on retiring to bed.
Caution should be observed when Terazosin is administered with other antihypertensive agents, avoid the possibility of significant hypotension. When adding Terazosin 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 Terazosin therapy.

Overdose Effects

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 noradrenergic vasopressor may also be needed.

Storage Conditions

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.
