Minoxidil experience in Australia 1974-1980

Area of Science:

• Cardiology
• Pharmacology

Background:

• Severe refractory hypertension poses significant challenges in patient management.
• Multiple therapeutic strategies are often required for resistant cases.

Purpose of the Study:

• To evaluate the efficacy and tolerability of minoxidil in patients with severe refractory hypertension.
• To assess blood pressure control and common side effects associated with minoxidil treatment.

Main Methods:

• A study involving 27 investigators assessed minoxidil in 101 patients with severe refractory hypertension.
• Patients had previously failed to respond to extensive multiple therapies.

Main Results:

• Minoxidil successfully controlled blood pressure in 71 out of 101 patients (70.3%).
• The most frequent side effects reported were fluid retention and hypertrichosis.
• A significant proportion of patients (71%) discontinued minoxidil due to intolerance.

Conclusions:

• Minoxidil demonstrates efficacy in controlling severe refractory hypertension.
• Intolerance and significant side effects limit its widespread use in this patient population.
