Propranolol HCL (propranolol hydrochloride) is a non-selective beta-adrenergic receptor blocker that helps the body manage excessive stress and cardiac activity. It is used to treat hypertension (high blood pressure), angina pectoris (chest pain), arrhythmias, essential tremor, and migraine prevention. Additionally, it’s often prescribed off-label for performance anxiety and social anxiety because it reduces the physical symptoms of nervousness. The “HCL” refers to the hydrochloride salt form of propranolol, which improves the medication’s stability and absorption. The active ingredient remains the same as in other propranolol formulations such as Inderal or APO-Propranolol. Propranolol HCL is available in tablets of 10 mg, 20 mg, 40 mg, 80 mg, and 120 mg. Extended-release formulations (Inderal LA) provide longer-lasting effects for patients needing 24-hour symptom control.
