Introduction to Midodrine Hydrochloride
Midodrine hydrochloride, marketed under the brand name ProAmatine, is a medication primarily used to treat symptomatic orthostatic hypotension (SOH), a condition characterized by a sudden drop in blood pressure upon standing, leading to dizziness or fainting. Here, we will delve into the recent clinical trials, market analysis, and future projections for this drug.
Clinical Trials and Regulatory Status
Initial Approval and Post-Approval Commitments
Midodrine hydrochloride was approved in 1996 under the FDA’s accelerated approval process (Subpart H) for the treatment of SOH. This approval was contingent on the completion of post-approval clinical trials to confirm the drug's clinical benefit[1][3][4].
Controversy and Additional Trials
Despite completing the required post-marketing trials and submitting the results to the FDA in 2005, the FDA deemed these trials inadequate and requested additional studies. Shire, the original NDA holder, disagreed with the FDA's assessment but agreed to conduct further clinical trials to resolve the issue. In 2011, Shire and the FDA agreed on a joint clinical trials proposal to confirm the clinical benefit of midodrine, with trials expected to be completed by the end of 2014[1][3].
Current Clinical Trial Status
The necessity for these additional trials was driven by the FDA's concern that the initial post-approval studies did not adequately demonstrate the clinical benefits of midodrine, such as improved ability to carry out daily activities. The ongoing and completed trials aim to provide conclusive evidence of midodrine's efficacy in treating SOH[1][3][4].

Safety and Contraindications
Important Safety Information
Midodrine hydrochloride is contraindicated in patients with severe organic heart disease, acute renal disease, urinary retention, pheochromocytoma, or thyrotoxicosis. It should not be used in patients with persistent and excessive supine hypertension. The drug can cause marked elevation of supine blood pressure, and its use should be carefully monitored[1][3].
Clinical Benefits and Limitations
While midodrine hydrochloride has been shown to significantly raise blood pressure in patients with SOH, the clinical benefits, such as improved ability to carry out daily activities, have not been fully verified. This has been a point of contention between the FDA and the drug's manufacturers[1][3][4].
