Effectiveness

How Terazosin Hydrochloride Affects Patients

Terazosin is a type of drug that helps block the actions of certain hormones in the body (alpha-1 adrenergic hormones) to help treat certain conditions.

How Terazosin Hydrochloride works in the body

Terazosin targets certain receptors found in the blood vessels and prostate. When those receptors are blocked, the smooth muscles in those areas relax, reducing blood pressure and improving urine flow. Terazosin has also been shown to stop cell growth and cause some prostate cells to die, a process called apoptosis. This is done by increasing the expression of certain factors like TGF-beta1, p27kip1, and caspase.

When to interrupt dosage

The proposed dosage of Terazosin Hydrochloride is contingent upon the ascertained condition, for example Ureteral Calculus, Hypertensive disease and Enlarged Prostate. The measure of dosage relies upon the technique of administration (e.g. Capsule, liquid filled or Capsule - Oral) as indicated in the table below.

Terazosin Hydrochloride Toxicity & Overdose Risk

If someone takes too much terazosin, they may have low blood pressure. To help control their heart rate and blood pressure, they should lie down and may need extra fluids or medicine to increase their blood pressure. It is important to monitor their kidney function. Since terazosin is strongly bound to proteins, dialysis is not likely to be very effective in removing the drug from the body. The lowest toxic dose of terazosin in mice is 5500mg/kg.

Terazosin Hydrochloride for Enlarged Prostate with Urination Problems

I began with a low dose of 1mg, and have since increased to 5mg in the morning and 5mg at night. I haven't experienced any negative side effects, save for feeling lightheaded if I stand up too quickly. The medication has been effective in controlling my urination symptoms, which is something I'm grateful for. Although I would prefer not to be taking medication at all, this treatment seems to be working well for me.

Terazosin Hydrochloride for Enlarged Prostate with Urination Problems

I find that this treatment is effective when I avoid bladder irritants. If I stick to one cup of green tea in the morning and no Diet Coke during the day, I can usually make it through the night without having to urinate. Without terasozin, I would get up 2-3 times a night to urinate.

Terazosin Hydrochloride for Enlarged Prostate with Urination Problems

I found the sexual side effects quite distressing. I lost the ability to ejaculate, and as a result, also lost the orgasm associated with it. I stopped taking it for that reason - then all the old urinary problems returned. So I'm back on it and have had to accept that lack of sexual fulfillment is now a part of my life.

The doctor prescribed this for me to help with high blood pressure caused by pain. Unfortunately, it made it difficult to concentrate and my vision got worse. I stopped taking it once the pain subsided, but my eyes are still blurry. Make sure you stay hydrated if you go on this medication.

Flomax gave me some really unpleasant side effects, so I had to switch to Terazosin. So far it's been working well for my BPH with only minor headaches. It's also a lot cheaper than Flomax, so that's a bonus.

Honestly, this was the worst headache I have ever experienced. I couldn't sleep at all, and felt nauseous and dizzy the entire time. My teeth even started hurting really badly. This drug is absolutely intolerable, and I still feel its effects 11 days later. So scary.

BPCARE Intervention for High Blood Pressure

18+
All Sexes
San Diego, CA

The goal of this randomized clinical trial is to determine whether a community health worker-delivered, multi-component behavioral intervention can improve antihypertensive medication adherence and blood pressure control among adult refugees with hypertension who are prescribed antihypertensive medications. The main questions it aims to answer are: 1. Does participation in the BPCARE intervention improve antihypertensive medication adherence compared to enhanced usual care? 2. Does participation in the BPCARE intervention improve blood pressure control and persistence over time compared to enhanced usual care? Researchers will compare participants randomized to the BPCARE intervention to those receiving enhanced usual care (hypertension information and a home blood pressure monitor) to determine the effects on medication adherence, blood pressure control, and persistence. Participants will: * Be randomly assigned to either the BPCARE intervention or enhanced usual care * Receive hypertension education and a home blood pressure monitor * Participate in community health worker-delivered sessions that include hypertension and medication education, motivational interviewing, problem-solving, and action planning (intervention arm only) * Complete questionnaires assessing medication adherence and related psychosocial factors * Have blood pressure monitored using connected home blood pressure devices * Complete pill counts to assess medication adherence over a nine-month follow-up period

In this study, the investigators are testing the effectiveness and implementation of the Community Health Workers (CHW)-delivered PILI Pasifika Program (PPP) Standard Facilitation or Enhanced Facilitation across 3 regions, the U.S. Affiliated Pacific Islands (USAPI), the continental U.S., and Hawai'i, among 600 Native Hawaiian and Pacific Islander (NHPI) participants in two settings, (clinical and non-clinical) over a 3-year period. The PPP is a 3-month lifestyle intervention that includes a Social Determinants of Health (SDOH) component and was NHPI-adapted from the Diabetes Prevention Program's Lifestyle Program, renamed to the PILI Lifestyle Program (PLP), which demonstrated effectiveness in improving weight, blood pressure, physical activity, and diet among NHPIs. The PPP consists of 8 lifestyle lessons and 4 SDOH activities delivered over a 3-month period. The investigators will conduct an effectiveness-implementation hybrid type 2 trial using a 3 (Region) x 2 (Setting) x 2 (Delivery Mode) factorial design. The long-term objective of this study is threefold: 1. To conduct an effectiveness-implementation hybrid 2 trial to test the effects of the PPP implementation strategies across different settings and modes of delivery among 600 NHPIs at risk for cardiometabolic-related conditions using an NHPI-approved and adapted evaluation framework. The investigators will also assess and compare the cost-effectiveness of the CHW-delivered PPP-Standard Facilitation and PPP-Enhanced Facilitation to support long-term sustainability. 2. To conduct a longitudinal Social Determinants of Health (SDOH) survey embedded within the trial to examine the reliability and validity of indices from 5 adapted SDOH instruments and to assess the associations between SDOH variables and chronic disease risk among NHPIs. 3. To implement and evaluate the contextually-based CHW training program on PPP delivery.

Dietary Interventions for Hypertension

18+
All Sexes
Birmingham, AL

Natriuretic peptides (NPs) are hormones produced by the heart and play an important role in maintaining cardiovascular health and have favorable metabolic benefits. Low NP levels are associated with an increased likelihood of the development of cardiometabolic diseases like diabetes and hypertension. NP levels are known to be highly heritable, with up to half of the differences in NP levels being explained by genetics. The investigators aim to describe the genetic architecture of NPs by examining the genetic variants associated with NPs, and generate and validate a polygenic score (PGS) for NPs. The investigators will use this NP PGS to examine the association of genetically determined NP levels with cardiometabolic and cardiovascular outcomes. The investigators will conduct a genotype-guided physiological clinical trial that aims to assess the genetic factors affecting NP levels and their impact on blood pressure and NP response to saline infusion, high-salt diet, and low-salt diet. These findings will help support personal medicine approaches to lower the increasing burden of hypertension in the United States.

Optilume vs Rezum for Enlarged Prostate

18+
Male
Montréal, Canada

Lower urinary symptoms (LUTS) affect older men and their frequency and severity increase with age. According to Berry et al., the histological diagnosis of benign prostatic hyperplasia (BPH) increases from 25% in the group age between 40 to 49 years to 80% in the group age between 70 to 79 years (1). However, this hyperplasia can lead to a bladder outlet obstruction (BOO) secondary to benign prostatic enlargement (BPE), causing storage and voiding symptoms, associated with a considerable impairment of the quality of life (2). Surgical therapy of BPH has continuously evolved in recent years. The current gold standard for the endoscopic treatment of BPH is the transurethral resection of the prostate (TURP). Other innovative techniques were developed including Urolift, transurethral laser enucleation (holmium, thulium) and Aquablation therapy. One of the latest technologies for the management of BPH are Optilume BPH Catheter System (Optilume®, Urotronic Inc, Minneapolis, USA) and Rezum Water Vapor Therapy (Rezum System, Bostocn Scientific, Marlborough, MA). The purpose of the present study is to compare between patient experience, symptom relief and functional improvement when using the Optilume BPH Catheter System (Optilume®, Urotronic Inc, Minneapolis, USA) and Rezum Water Vapor Therapy (Rezum System, Boston Scientific, Marlborough, MA).
