5 Small Drug Stocks to Buy as Tariff-Related Uncertainty Looms

By Kinjel Shah | April 23, 2025, 9:32 AM
The biotech industry has been under pressure due to the global uncertainty caused by the tariff war. Though pharmaceuticals have been exempted in the first round of reciprocal tariffs, they could well be Trump’s target in the next round. Though the Trump administration has implemented a 90-day pause on all trading partners, excluding China, when imposed, tariffs on pharmaceutical imports can lead to potential disruptions to global supply chains and increased production costs.

Biotech stocks have been under pressure ever since Trump appointed Robert F. Kennedy Jr., a well-known vaccine skeptic, as the new HHS secretary. The resignation of a key FDA regulator, Peter Marks, who supported faster FDA approval, reportedly ousted by RFK Jr,has also led to some concerns.

However, amid all the headwinds, the Zacks Medical-Drugs industry is showing promising trends due to positive pipeline news and regulatory successes. In Trump’s second innings, the biotech industry hopes to witness more innovation and mergers and acquisitions (M&A) activity. Innovation is at its peak for the industry, with key spaces like rare diseases, next-generation oncology treatments, obesity, immunology and neuroscience attracting investor attention. R&D innovation is likely to remain a major focus area in 2025 as well. These factors should continue to drive stocks like Aurinia Pharmaceuticals AUPH, Heron Therapeutics HRTX, Esperion Therapeutics ESPR, Pyxis Oncology PYXS and Plus Therapeutics PSTV.

Industry Description

The Zacks Medical-Drugs industry comprises small and some medium-sized drug companies that make medicines for both human and veterinary use. We have a separate industry outlook discussion on big drugmakers. Small drugmakers have a limited portfolio of marketed drugs or no commercial-stage drugs at all. Some drugmakers are dependent on just one marketed drug or pipeline candidate. For such companies, upfront or milestone payments from collaboration partners — in most cases, their larger counterparts — are the main sources of revenues. These companies need ample free cash flow to fund their R&D activities.

Factors Shaping the Future of the Medical-Drugs Industry

Pipeline Success: The success or failure of key pipeline candidates in clinical studies can significantly drive the stock price of industry players. Successful innovation and product line extensions in important therapeutic areas and strong clinical study results may act as important catalysts for the stocks.

Strong Collaboration Partners: These companies regularly seek external partners and collaborators for complementary strengths. A partnership deal with a popular drugmaker is a good sign about the potential of small pharma companies, especially when an equity investment is included in the deal. M&A deals are in full swing in the sector, signaling growth.

Investment in Technology for Innovation: For smaller companies, succeeding in a shifting global market and evolving healthcare landscape requires adopting innovative business models, investing in new technologies and increasing investments in personalized medicines. Over the past few years, scientific and technological advancements have made it possible to develop personalized therapies. Other than that, adoption and information exchange through the meaningful use of health IT, development of therapies that improve overall patient outcomes and investment in developing and emerging markets are some of the key priorities for drug companies. Artificial intelligence and machine learning techniques are being used for the rapid advancement of drug discovery and target identification processes.

Pipeline Setbacks: The smaller companies have their share of risk in the form of unstable cash flows. Also, the failure of key pipeline candidates in pivotal studies and regulatory and pipeline delays can be huge setbacks for these smaller companies and significantly hurt their share prices.

5 Drug Stocks to Bet On

Heron Therapeutics: Redwood City, CA-based Heron Therapeutics’ key marketed drug is Zynrelef, a non-opioid dual-acting local anesthetic for post-operative pain for a wide range of surgical procedures. Zynrelef sales rose 44.1 % in 2024. Heron is optimistic that the drug should record transformational growth in 2025, driven by its expanded label indications, which now cover an estimated 17 million procedures annually. In addition, the launch of Vial Access Needle or VAN, which simplifies the preparation and administration of Zynrelef, and the distributor partnership with CrossLink Life Sciences to expand promotional efforts for Zynrelef should also contribute to Zynrelef sales growth in 2025. Its other commercial products, Aponvie, Cinvanti and Sustol are also generating decent sales. Overall, the company’s revenues and margins are growing.

The stock of Heron Therapeutics has risen 40.5% so far this year. The consensus estimate for 2025 has narrowed from a loss of 5 cents per share to breakeven over the past 60 days. The company has a Zacks Rank #1 (Strong Buy). You can see the complete list of today’s Zacks #1 Rank stocks here. .

Price and Consensus: HRTX

Esperion Therapeutics: Ann Arbor, MI-based Esperion Therapeutics has two approved drugs — Nexletol (bempedoic acid) and Nexlizet (bempedoic acid/ezetimibe combination pill) — in its portfolio. Nexletol and Nexlizet have shown promising uptake and prescription trends since their launch in 2020. The drugs’ prescription trends have improved sequentially in recent quarters, with the trend expected to continue. The inclusion of the CLEAR Outcome study data has expanded the drugs’ label, allowing them to cater to a larger patient population. Esperion’s efforts to expand the label of Nexletol and Nexlizet also look promising. Esperion is developing two triple combination products with Nexletol/Nexlizet in combination with either atorvastatin or rosuvastatin.

Esperion Therapeutics’ stock has declined 57.7% in the year-to-date period. The consensus estimate for 2025 loss per share has narrowed from 13 cents to 9 cents over the past 60 days. The company has a Zacks Rank #2 (Buy).
